Abstract wireless communication eliminates obtrusive cables associated with wearable sensors and considerably increases patient comfort during measurement and collection of medical data. Wireless communication is very popular in recent years and plays a significant role in telemedicine and homecare applications. Bluetooth technology is one of the most commonly used wireless communication types in medicine. This paper describes the design of a universal wireless communication device with excellent price/performance ratio. The said device is based on the low-cost RN4020 Bluetooth module with Microchip Low-energy Data Profile (MLDP) and due to low-power consumption is especially suitable for the transmission of biological signals (ECG, EMG, PPG, etc.) from wearable medical/personal health devices. A unique USB dongle adaptor was developed for wireless communication via UART interface and power consumption was evaluated under various conditions.

With the rapid growth of Internet of Things (IoT) devices around the world, thousands of mobile users share many data with each other daily. IoT communication has been developed in the past few years to ensure direct connection among mobile users. However, wireless vulnerabilities exist that cause security concerns for IoT device-to-device (D2D) communication. This has become a serious debate, especially in smart environments where highly sensitive information is exchanged. In this paper, we study the security requirements in IoT D2D communication. In addition, we propose a novel authentication approach called Secure Key Exchange with QR Code (SeKeQ) to verify user identity by ensuring an automatic key comparison and providing a shared secret key using Diffie-Hellman key agreement with an SHA-256 hash. To evaluate the performance of SeKeQ, we ran a testbed using devices with a WiFi-Direct communication interface. The obtained results depict that our proposal can offer the required security functions including key exchange, data confidentiality, and integrity. In addition, our proposal can reach the same security performances as MANA (Manual Authentication) and UMAC (Universal-Hashing Message Authentication Code) but with 10 times fewer key computations and reduced memory occupancy.

In IoT-based smart healthcare services, the heterogeneity of connected wearable sensing devices open up a wide opportunity to develop various healthcare services. However, it also poses an interoperability challenge since each sensing device and application may have different communication mechanisms. Considering that challenge, web platform can be seen as a promising candidate for providing an interoperability layer as we can abstract various devices as single representation i.e. web resource. In this paper, we propose the design of middleware for enabling efficient web of things access over healthcare wearable devices. The proposed middleware consists of three components: gateway-to-cloud device, messaging service and data access interface. The gateway-to-cloud device has a role to perform low level sensor data collection from various wearable sensing device through bluetooth low energy (BLE) communication protocol. Collected data are then relayed to the cloud IoT platform using a lightweight MQTT messaging protocol. In order to provide device abstraction along with access to the stored data, the system offers two kind of interfaces: the Restful HTTP identified by unique universal resource locator (URL) for batch access and MQTT websocket interface identified by unique topic to accommodate access on sensing data in near real time stream manner.

The research project UP-Prosa, a German acronym for universal and unified platform for planning, programming, controlling and evaluating processes, of measuring, aims at realizing a platform to design and control processes of geometry measurements, which supports a broad variety of measuring devices via one user interface. Based on Windows Operating System (OS) a software was developed able to control inspection devices for different types of geometry measurements (coordinate measuring machine, form, roughness, gear) and manufacturers by one defined communication protocol. This uniform user interface contains the programming of measurement processes, evaluation algorithms with standardized methods, as well as abilities to generate record pages at the users expectations. At the level of geometric measuring devices a universal controlling software called Prosa InterCommunicator (Prosa-ICom) was designed. Prosa-ICom communicates via network with the user interface and translates the defined protocol into a measuring device specific form. The internal structure is extendable and so it seems to be appropriate for both new developments and upgrades (retrofit) for all kinds of geometric measuring devices.

The Universal Plug and Play (UPnP) technology offers pervasive communication across heterogeneous devices in a home or small office network. The UPnP specifications are available for devices only to be interoperable together in a home or small office network. This paper proposes an extension of the UPnP technology for application interoperability in a home or small office network. This paper provides an UPnP Application Architecture as an extension to the existing UPnP Device Architecture. This extension enhances the feature of UPnP from device interoperability to application interoperability which enables the applications to discover, control and share data with each other in a home or small office network despite of their device type and operating system. In addition to the UPnP Application Architecture, the UPnP Application Template and UPnP Application Service Template are defined towards the development of UPnP-enabled applications that run on heterogeneous devices in a home or small office network.

Full textAbstract:
The widespread application of wireless communication technology brings great convenience to people, but security and privacy problems also arise. To assess and guarantee the security of wireless networks and user devices, discovering and identifying wireless devices become a foremost task. Currently, effective device identification is still a challenging issue, as device fingerprinting requires huge training datasets and is difficult to expand, and rule-based identification is not accurate and reliable enough. In this paper, we propose WND-Identifier, a universal and extensible framework for the identification of wireless devices, which can generate high-precision device labels (vendor, type, and product model) efficiently without user interaction. We first introduce the concept of device-info-related network protocols. WND-Identifier makes full use of the natural language features in such protocol messages and combines with the device description in the welcome page, thereby utilizing extraction rules to generate concrete device labels. Considering that the device information in the protocol messages may be incomplete or forged, we further take advantage of the application logic independence and stability of the device-info-related protocol, so as to build a multiprotocol text classification model, which maps the device to a known label. We conduct experiments in homes and public networks and present three application scenarios to verify the effectiveness of WND-Identifier.

Abstract This paper is aimed at the description of hardware design, software equipment and the functionality of the second evolution of the intelligent multipurpose input/output microcontroller converter and control unit designed and assembled by the authors. Preceding stages of the unit development are concisely overviewed first, the deficiencies of which give rise to the primary motivation of this contribution. Then separate hardware parts of the novel unit are described in detail including electronic schematic diagrams. The device firmware and software capabilities are introduced as well. The advantages of the unit are highlighted compared to older versions. Its functionality, performance and efficiency are then verified by a laboratory control-related dynamic responses measurement example. In the contrary to previous evolutions, a more compact hardware design, increased A/D and D/A converter resolutions, added USB communication capability, better and more accurate analog circuits with more advanced operation amplifiers, the use of OLED instead of LCD display, the pulse-width modulated signal generated by the microcontroller unit itself can be considered among the most important improvements. Moreover, the direct use of the serial link may reduce noise significantly and makes the device more universal.

The use of IoT devices such as wearable digital devices based on mobile devices is increasingly evident. In IoT-based environment, communication protocol of IoT category and lightweight special environment software are used instead of universal network configuration. Due to the operating structure of IoT, preparation of countermeasures to automatically analyze IoT software vulnerabilities based on artificial intelligence should be considered. Because of the rapid growth of IoT equipment and the expectation that there will be a sharp increase in the need to identify facts about vulnerabilities and improper use associated with IoT services naturally. It is necessary to apply artificial intelligence technology for classification and automatic collection and analysis of IoT vulnerabilities for wearable devices and smart home devices through artificial intelligence analysis technology. Sequentially, To acquire the data from the device, internal data and network data of the specified device after searching the protocol of the IoT device, it is possible to cope with IoT software vulnerability applying AI intelligence analysis method to related data. In this paper, we investigate software vulnerabilities in IoT environment and propose a technique to cope with ioT vulnerabilities through artificial intelligence.

Abstract Modern surgical departments are characterized by a high degree of automation supporting complex procedures. It recently became apparent that integrated operating rooms can improve the quality of care, simplify clinical workflows, and mitigate equipment-related incidents and human errors. Particularly using computer assistance based on data from integrated surgical devices is a promising opportunity. However, the lack of manufacturer-independent interoperability often prevents the deployment of collaborative assistive systems. The German flagship project OR.NET has therefore developed, implemented, validated, and standardized concepts for open medical device interoperability. This paper describes the universal OR.NET interoperability concept enabling a safe and dynamic manufacturer-independent interconnection of point-of-care (PoC) medical devices in the operating room and the whole clinic. It is based on a protocol specifically addressing the requirements of device-to-device communication, yet also provides solutions for connecting the clinical information technology (IT) infrastructure. We present the concept of a service-oriented medical device architecture (SOMDA) as well as an introduction to the technical specification implementing the SOMDA paradigm, currently being standardized within the IEEE 11073 service-oriented device connectivity (SDC) series. In addition, the Session concept is introduced as a key enabler for safe device interconnection in highly dynamic ensembles of networked medical devices; and finally, some security aspects of a SOMDA are discussed.

In order to incorporate different communication standards into a single device, a compact quad-band slot antenna is proposed in this paper. The proposed antenna is composed of a dielectric substrate, T-shaped microstrip patch with a circle slot and an inverted L-slot, and a comb-shaped ground on the back of the substrate. By adopting these structures, it can produce four different bands, while maintaining a small size and a simple structure. Furthermore, a prototype of the quad-band antenna is designed and fabricated. The simulated and measured results show that the proposed antenna can operate over the 1.79–2.63 GHz, 3.46–3.97 GHz, 4.92–5.85 GHz, and 7.87–8.40 GHz, which can cover entire PCS (Personal Communications Service, 1.85–1.99 GHz), UMTS (Universal Mobile Telecommunications System, 1.92–2.17 GHz), WCDMA (wideband code-division multiple access, 2.1 GHz), Bluetooth (2.4–2.48 GHz), WiBro (Wireless Broad band access service, 2.3–3.39 GHz), WLAN (Wireless Local Area Networks, 2.4/5.2/5.8 GHz), WiMAX (Worldwide Interoperability for Microwave Access, 2.5/3.5/5.5 GHz), and X-band SATcom applications (7.9~8.4 GHz).

Full textAbstract:
By virtue of the rapid development of the Information and Communication Technology (ICT), people have owned various devices connected to the Internet to enjoy various emerging application services, such as multimedia related services. IP Multimedia Subsystem (IMS) is the integration platform for multimedia application services and provides a rich feature set of converged services in the Next Generation Network (NGN). IMS services are accessed by a user anytime and anywhere through his/her personal self IMS device, e.g., mobile device, equipped with a Universal Subscriber Identity Module (USIM) card. People have owned various devices connected to the Internet at homes or offices. However, some devices can not access IMS services without USIM cards embedded, which is called non-IMS devices. People wish that more devices without USIM cards embedded should be connected to the Internet on which IMS services are accessed in addition to the mobile devices equipped with USIM cards. Accordingly, we propose an Open Service Gateway Initiative (OSGi)-based IMS service gateway, in which OSGi technology is the dynamic module system for JAVA. The proposed gateway is authorized by a personal self IMS device such that IMS services are accessed by non-IMS devices, in this paper. Moreover, these non-IMS devices rely on different networks to access technologies and network protocols and the IMS service gateway proposed here adopts the OSGi framework for no problem of integration.

Full textAbstract:
Human motion detection and activity recognition are becoming vital for the applications in smart homes. Traditional Human Activity Recognition (HAR) mechanisms use special devices to track human motions, such as cameras (vision-based) and various types of sensors (sensor-based). These mechanisms are applied in different applications, such as home security, Human–Computer Interaction (HCI), gaming, and healthcare. However, traditional HAR methods require heavy installation, and can only work under strict conditions. Recently, wireless signals have been utilized to track human motion and HAR in indoor environments. The motion of an object in the test environment causes fluctuations and changes in the Wi-Fi signal reflections at the receiver, which result in variations in received signals. These fluctuations can be used to track object (i.e., a human) motion in indoor environments. This phenomenon can be improved and leveraged in the future to improve the internet of things (IoT) and smart home devices. The main Wi-Fi sensing methods can be broadly categorized as Received Signal Strength Indicator (RSSI), Wi-Fi radar (by using Software Defined Radio (SDR)) and Channel State Information (CSI). CSI and RSSI can be considered as device-free mechanisms because they do not require cumbersome installation, whereas the Wi-Fi radar mechanism requires special devices (i.e., Universal Software Radio Peripheral (USRP)). Recent studies demonstrate that CSI outperforms RSSI in sensing accuracy due to its stability and rich information. This paper presents a comprehensive survey of recent advances in the CSI-based sensing mechanism and illustrates the drawbacks, discusses challenges, and presents some suggestions for the future of device-free sensing technology.

Full textAbstract:
The article is devoted to the review of possibilities of creation of special technical means on the basis of SDR devices and principles of construction of transceiver devices which have a possibility of use at performance of various tasks and the purposes. The principles of construction of SDR devices and their features are considered in the article. When creating special hardware, the basic principle is a flexible architecture that can be changed with the help of software. This allows to organize communication between two or more different types of devices, for example, to switch between communication channels and change the type of modulation. When using SDR devices, it is possible to significantly simplify the technical part. The hardware platform can be quickly reprogrammed to support new communication and data exchange standards. Digital signal processing provides greater speed and it is easier to maintain than other analog systems. It is noted that the SDR receiver is a universal device that can combine the functions of various radio devices. Following the concept of SDR, the author concludes that the ideal SDR receiver should contain as few elements as possible, while an important factor in the use of SDR devices is the replacement of most analog components. It is emphasized that devices that are built on an analog element base have a much higher complexity of design than SDR devices and do not have the flexibility required in today’s conditions of rapid change in communication standards.

Full textAbstract:
Formation of scatternet using Bluetooth devices increases device tractability thereby inviting new networking applications to be designed on it. In this paper we propose Bluetooth Scatternet Formation and Routing Protocol (BSFRP). It is a distributed protocol that handles node mobility and enables multi-hop communication. BSFRP defines rules for topology discovery, scatternet formation and routing. The scatternet phase of the protocol works on the principle of leader election. For routing, AODV is modified to address the constraints of scatternets. It improves the AODV route discovery phase by considering hop count, residual node's power, and route lifetime for best route selection. Simulation results show that the scatternet formed by BSFRP has the following properties: the number of piconets formed is close to the universal lower bound, each device on an average does not assume more than 1.15 roles, and the scatternet does not contain any master-slave bridge.

Full textAbstract:
With the help of edge computing, the Internet of Things (IoT) provides users with efficient data transmission and processing capabilities. As a main control device of the IoT and the communication portal of edge computing, user terminals represented by Android devices have potential security risks in IoT. Trusted computing is a universal method to construct trusted environment for computing platforms. However, due to the strict space, cost, and power limitations, commercial Android devices would not be applicable to implement a dedicated onboard chip or the software Trusted Platform Module (TPM) by modifying its firmware. We have designed a practical Trusted Software Base (TSB) for mobile devices to enhance their security. By using the secure TF card as the hardware to provide secure storage and cryptographic capabilities, we implement the trusted boot and trust extension for applications on a commercial device to verify the feasibility of the TSB to ensure a trusted environment for users. Our implementation does not require any modification to the firmware or any additional hardware other than the secure TF card. Experimental evaluation shows that our method can provide trusted computing capability for commercial Android devices with low performance overheads.

Full textAbstract:
AbstractHearing aids are often not sufficient for optimal communication between a listener and a talker. Therefore, numerous options for wireless connectivity between the listener and the talker designed to improve communication have become widely available. From the original wireless option of the induction loop system, most of the current solutions involve a digital signal with high quality and limited interference. Many are proprietary and only operate with a given manufacturer's devices, while others are more universal as long as the digital receiver can be connected to the listener's personal device. In addition, connectivity options to assist those with hearing loss are now readily available on the smartphone which can be used as a remote microphone. Therefore, it is paramount that the available wireless protocols be considered relative to the listener's experience with wireless technology so that solutions may be offered that are efficient, economical, and effective.

Full textAbstract:
Weighted spiking neural P systems with anti-spikes (AWSN P systems) are proposed by adding anti-spikes to spiking neural P systems with weighted synapses. Anti-spikes behave like spikes of inhibition of communication between neurons. Both spikes and anti-spikes are used in the rule expressions. An illustrative example is given to show the working process of the proposed AWSN P systems. The Turing universality of the proposed P systems as number generating and accepting devices is proved. Finally, a universal AWSN P system having 34 neurons is proved to work as a function computing device by using standard rules, and one having 30 neurons is proved to work as a number generator.

Full textAbstract:
This paper presents a new universal programmable portable measuring device (PMD) as a complete, accurate, and efficient solution for monitoring and technical diagnostics of industrial fluid power systems. PMD has programmable functions designed for recording, processing, and graphical visualization of measurement results at the test stand or the place of operation of fluid power systems. PMD has a built-in WiFi communication module for transferring measurement data via Industrial Internet of Things (IIoT) technology for online remote monitoring of fluid power systems. PMD can be programmed for a variety of measuring tasks in servicing, repairing, diagnosing, and monitoring fluid power systems. For this purpose, the fluid dynamic quantity, mechanical quantity, and electrical quantity can be measured. The adjustment of the PMD to the indirect measurement of leakage flow rate in a compressed air system (CAS) is presented in detail. Measuring instruments and PMDs were connected to a branch of the pipeline. The tests used the measurement system to estimate the leakage flow rate through air small nozzles, as well as other CAS indicators.

Follow-up for ongoing management and monitoring of patients is important in clinical practice and research. While common, telephone follow-up is resource intensive and, in our experience, yields low success rates. Electronic communication using mobile devices including smartphones and tablets can provide efficient alternatives — including SMS (text), online forms and mobile apps. To assess attitudes towards electronic follow-up, we surveyed 642 parents and carers at Perth Children’s Hospital, targeting demographics, device ownership and attitudes towards electronic follow-up. Mobile phone ownership was effectively universal. Almost all respondents were happy to communicate electronically with the hospital. Promisingly, 93.2% of respondents were happy to receive follow-up SMSs from the hospital and 80.3% were happy to reply to SMS questions. There was less enthusiasm regarding other modalities, with 59.9% happy to use a website and 69.0% happy to use a mobile app. The results support the introduction of electronic communication for follow-up in our paediatric population.

Full textAbstract:
Hydrocephalus is a medical condition characterized by the abnormal accumulation of cerebrospinal fluid (CSF) within the cavities of the brain called ventricles. It frequently follows pediatric and adult congenital malformations, stroke, meningitis, aneurysmal rupture, brain tumors, and traumatic brain injury. CSF diversion devices, or shunts, have become the primary therapy for hydrocephalus treatment for nearly 60 years. However, routine treatment complications associated with a shunt device are infection, obstruction, and over drainage. Although some (regrettably, the minority) patients with shunts can go for years without complications, even those lucky few may potentially experience one shunt malfunction; a shunt complication can require emergency intervention. Here, we present a soft, wireless device that monitors distal terminal fluid flow and transmits measurements to a smartphone via a low-power Bluetooth communication when requested. The proposed multimodal sensing device enabled by flow sensors, for measurements of flow rate and electrodes for measurements of resistance in a fluidic chamber, allows precision measurement of CSF flow rate over a long time and under any circumstances caused by unexpected or abnormal events. A universal design compatible with any modern commercial spinal fluid shunt system would enable the widespread use of this technology.

Full textAbstract:
Causal clauses introduced by yīnwèi in Chinese can have either an initial position or a final position with regard to the main clause. While traditional grammars have treated the initial sequence as the default form, numerous discourse-based studies have shown just the opposite. However, few have attempted to explain why both sequence orders exist and why they have skewed distribution patterns across discourse registers. In this paper we use a telephone conversation corpus and a written Chinese corpus as data and provide a comprehensive analysis of the usage patterns. Our main findings are that final and initial causal clause sequences are ostensibly two different linguistic constructions, functioning as an interactional device and an information-sharing device, respectively. Quantitative distributional disparities are seen as a function of the discourse utilities of the linguistic devices in question and the communicative demands of different registers. From a cross-linguistic perspective, our findings raise questions about the ways in which universal and language-specific properties of clause sequencing can be better understood.

Full textAbstract:
The design of a robust communication among two different sensory disabilities (Deaf vs. Blind) remains an emerging field of research in disability healthcare communication system design. As an important part of modern technology, android and iPhone applications are frequently used in designing such communication systems. However, there is no 'one-size-fits-all' in case of different sensory disability health communication design. Hence, an in-depth understanding of their requirement, media preferences, similarity and difference and up-to-date technology usability are plausible towards universal and personalized communication system design. This research addresses such complex issues and performs a study involving two different types of disabilities (deaf and blind) communication. As a part of healthcare analytics, critical incidences are recorded and corresponding complexities are measured in order to evaluate communication protocol with social signal processing. Communication flow diagram, complexity analysis and critical incidence are quantified to improve communication protocols. Moreover, the uniqueness of disability can be personalized through this process which has valuable implications in rehabilitation and multi-purpose healthcare communication device development.

For a long time, a common opinion among policy-makers was that the digital divide problem would be solved when a country’s Internet connection rate reaches saturation. However, scholars of the second-level digital divide have concluded that the divides in Internet skills and type of use continue to expand even after physical access is universal. This study—based on an online survey among a representative sample of the Dutch population—indicates that the first-level digital divide remains a problem in one of the richest and most technologically advanced countries in the world. By extending basic physical access combined with material access, the study finds that a diversity in access to devices and peripherals, device-related opportunities, and the ongoing expenses required to maintain the hardware, software, and subscriptions affect existing inequalities related to Internet skills, uses, and outcomes.

The current researches in the development of portable cardiograph for primary preclinical diagnostics are focused on the choice of optimal design parameters of device and the incensement of noise immunity of medical equipment. Uninvestigated parts of general matters defining. This article focuses on the design development of the portable electrocardiograph with built-in GSM module for operation in telemedicine systems. The research objective is the design of the portable electrocardiograph for telemedicine that has a convenient interface for device control, is equipped with means of communication with cardiac care centers, has universal ports for information output to external drives and connection of additional devices, is as ergonomic as possible, meets safety, reliability and energy efficiency requirements. The statement of basic materials. The main design requirements to portable electrocardiographic equipment are formulated. The basic functional units of the device are chosen and its electronic block diagram is synthesized. The computer simulation of processes and parameters of the circuitry of the instrumentation amplifier functionality at given operating temperatures proves the validity of proposed circuit design. The constructive implementation of the schematic diagram is designed. The device constructive parameters that meet the requirements of telemedicine most closely are defined. Conclusions. The key features of the designed portable electrocardiograph with GSM module are: the embodiment in folding form-factor, the availability of GSM module, the constant connection of ECG electrodes via integrated ECG cable. The embodiment in folding form-factor optimizes ergonomic characteristics of the device. The replacement of non-integral ECG cable with integrated one reduces the intensity of internal noise and reduces time to prepare the device for work. Builtin GSM module provides affordable communication with specialized medical facilities, thus reducing the duration of the diagnostics and increasing the efficiency of the medical care in non-ambulatory out-hospital an outpatient setting.

Since its invention, the Internet has changed the world, but above all, it has connected people. With the advent of the Internet of Things, the Internet connects things today much more than people do. A large part of the Internet of Things consists of IoT controlled Smart Home devices. The Internet of Things and the Smart Home have become an increasingly important topic in recent years. The growing popularity of Smart Home devices such as Smart TVs, Smart Door Locks, Smart Light Bulbs, and others is causing a rapid increase in vulnerable areas. In the future, many IoT devices could be just as many targets. The many new and inexperienced manufacturers and the absence of established uniform standards also contribute to the precarious situation. Therefore, new methods are needed to sensitize and detect these threats. In this paper, different existing approaches like those of the National Institute of Standards and Technology (NIST) and the Open Web Application Security Project (OWASP) are combined with concepts of this work like the Smart Home Device Life Cycle. In the context of this paper, a universal 31-page question-based test procedure is developed that can be applied to any Smart Home device. Based on this new, innovative security checklist, the communication between device, app, and the manufacturer's servers, as well as the firmware of IoT devices, can be analyzed and documented in detail. In the course of this paper, also a handout in the abbreviated form will be created, which serves the same purpose.

It is convenient and the norm to have both data and power cables (battery charge) integrated as a single Universal Serial Bus (USB) cable for today’s mobile devices. While the data component of the cables serves as the channels for data communication, the power channel charges the mobile devices through an adapter connected to an Alternating Current (A/C) socket or directly to a USB port. This convenient and seemingly harmless design could also serve as a medium through which malicious hacks are carried out on the connected mobile devices as studies and recent experimentations has shown. This hacking variant called Juice Jacking now serve as a potential avenue for mobile device exploitation, especially in developing economies where poor power grid infrastructures has allowed for indiscretions in charging devices from any available. This paper formulates a simple architecture for Juice Jacking cyber-crime, review prove-of-concept experimentation for Juice Jacking from available literatures, identifies significant threats and levels of impact of this cyber-crime on the community. It also highlights strategies that could mitigate juice jacking in developing economies.

In the present scheme of the world, the problem of shortage of power is seen across the world which can be a vulnerability to various communication securities. The scope of proposed research is that it is a step towards completing green communication technology concepts. In order to improve energy efficiency in communication networks, we designed UART using different nanometers of FPGA, which consumes the least amount of energy. This shortage is happening because of expanding of industries across the world and the rapid growth of the population. Therefore, to save the power for our upcoming generation, the globe is moving towards the concept and ideas of green communication and power-/energy-efficient gadget. In this work, a power-efficient universal asynchronous receiver transmitter (UART) is implemented on 28 nm Artix-7 field-programmable gate array (FPGA). The objective of this work is to reduce the power utilization of UART with the FPGA device in industries. To do this, the same authors have used voltage scaling techniques and compared the results with the existing FPGA works.

Purpose – This study aims to examine the usability of three popular electronic reading devices (e-readers) to determine which device provides the best functionality for individuals with print disabilities. Adaptability and flexibility for use with assistive technology are also evaluated. Design/methodology/approach – This study reports the results of a usability test of e-readers and their potential for use by individuals with print disabilities. Students enrolled in a School of Library and Information Science evaluated and compared the devices through a series of tasks designed to measure functionality. Participants completed a series of questionnaires and engaged in small group discussion about the efficacy of the devices. Likert scales and open-ended evaluation were employed in the evaluation and analysis. Findings – Two of the three devices examined offered no accessibility features for individuals with low or no vision who require assistive technologies to use information and communication technologies. The third device, while offering greater universal access functionality for individuals with mild-to-moderate print disabilities, also had weaknesses for individuals with severe print disabilities. Originality/value – With the rapid deployment of e-readers, little research has been completed measuring the accessibility and functionality for individuals with print disabilities in library or educational environments. The paper provides data on the usability of e-readers for users with print disabilities and recommendations for adopting e-reader use in libraries and educational environments. It will inform and guide information professionals seeking to provide greater access to resources for patrons with specialized access needs.

In order for a Mobile Device (MD) to support the Licensed Shared Access (LSA), the MD should be reconfigurable, meaning that the configuration of a MD must be adaptively changed in accordance with the communication standard adopted in a given LSA system. Based on the standard architecture for reconfigurable MD defined in Working Group (WG) 2 of the Technical Committee (TC) Reconfigurable Radio System (RRS) of the European Telecommunications Standards Institute (ETSI), this paper presents a procedure to transfer control signals among the software entities of a reconfigurable MD required for implementing the LSA. This paper also presents an implementation of a reconfigurable MD prototype that realizes the proposed procedure. The modem and Radio Frequency (RF) part of the prototype MD are implemented with the NVIDIA GeForce GTX Titan Graphic Processing Unit (GPU) and the Universal Software Radio Peripheral (USRP) N210, respectively. With a preset scenario that consists of five time slots from different signal environments, we demonstrate superb performance of the reconfigurable MD in comparison to the conventional nonreconfigurable MD in terms of the data receiving rate available in the LSA band at 2.3–2.4 GHz.

Control and measuring equipment is one of the first places in terms of breadth and efficiency of MP-tools. The microprocessor device (MPP) built into the measuring device expands its possibilities, adds new qualities for vibrating machines. Such a device is called programmable (PrVP); WFP can perform the following functions: - control (issuance of control information to all components of the device, reconfiguration of the structure of the device in case of failures of individual units, the formation of control signals to display information, switching different control algorithms); - control of efficiency, reliability of results, diagnostics and localization of malfunctions; - digital information processing (calibration of the device, calculation of errors, determination of minimum and maximum values of parameters, enumeration of parameters, calculation of instantaneous power and signal energy, linearization, information compression, approximation, scaling, normalization, correction, calculation of tolerances, average values, logs , exponentiation, root extraction, transformation of a form from a fixed comma into a floating form and back); - organization of communication with the human operator (exemption from routine operations, such as adjustment, calculation of deviations, etc.; presentation of information in a convenient and accessible for human view form; software support for a functional keyboard that replaces individual control knobs; ensuring the choice of conflict-free position of switches in devices with difficult control); - connection with the system and other devices (implementation of various interface functions, conversion of data formats, adaptation to various input signals). To perform these functions requires the development of an appropriate structure and software MPU. You can implement the following structures for vibrating machines: - universal micro-computer with standard or special programming system; the units of the measuring instrument are connected as external devices - using the address space allocated for external devices; - micro-computers with limited capabilities (for example, limited address space - part of the address bus is given to the addresses of the units of the measuring instrument, while the capacity of RAM is reduced); - special purpose - on the basis of programmable LSI or sectional MP-sets with special software or firmware. The structure of the first type is expedient at development of difficult multipurpose measuring means. The second has fewer features, but requires less hardware, it is useful when building measuring instruments with a small number of blocks and measuring functions. The structure of the third type is aimed at the optimal solution of the measurement problem, requires software development (command systems, microcommands).

Full textAbstract:
Low-Power Wide-Area Network (LPWAN) is an enabling Internet-of-Things technology that supports long-range, low-power, and low-cost connectivity to numerous devices. To avoid the crowd in the limited ISM band (where most LPWANs operate) and cost of licensed band, the recently proposed Sensor Network over White Spaces (SNOW) is a promising LPWAN platform that operates over the TV white spaces. As it is a very recent technology and is still in its infancy, the current SNOW implementation uses the Universal Software Radio Peripheral devices as LPWAN nodes, which has high costs (≈$750 USD per device) and large form-factors, hindering its applicability in practical deployment. In this article, we implement SNOW using low-cost, low form-factor, low-power, and widely available commercial off-the-shelf (COTS) devices to enable its practical and large-scale deployment. Our choice of the COTS device (TI CC13x0: CC1310 or CC1350) consequently brings down the cost and form-factor of a SNOW node by 25× and 10×, respectively. Such implementation of SNOW on the CC13x0 devices, however, faces a number of challenges to enable link reliability and communication range. Our implementation addresses these challenges by handling peak-to-average power ratio problem, channel state information estimation, carrier frequency offset estimation, and near-far power problem. Our deployment in the city of Detroit, Michigan, demonstrates that CC13x0-based SNOW can achieve uplink and downlink throughputs of 11.2 and 4.8 kbps per node, respectively, over a distance of 1 km. Also, the overall throughput in the uplink increases linearly with the increase in the number of SNOW nodes.

Full textAbstract:
One possibility to provide mobile multimedia in domestic multimedia systems is the use of Universal Plug and Play Audio Visual (UPnP-AV) devices. In a standard UPnP-AV scenario, multimedia content provided by a Media Server device is streamed to Media Renderer devices by the initiation of a Control Point. However, there is no provisioning of context-aware multimedia content customization. This paper presents an enhancement of standard UPnP-AV services for home multimedia environments regarding context awareness. It comes up with context profile definitions, shows how this context information can be queried from the Media Renderers, and illustrates how a Control Point can use this information to tailor a media stream from the Media Server to one or more Media Renderers. Moreover, since a standard Control Point implementation only queries one Media Server at a time, there is no global view on the content of all Media Servers in the UPnP-AV network. This paper also presents an approach of multimedia content integration on the Media Server side that provides fast search for content on the network. Finally, a number of performance measurements show the overhead costs of our enhancements to UPnP-AV in order to achieve the benefits.

Full textAbstract:
This article draws on the findings of in-depth interviews with consumers of portable storage devices in Melbourne, Australia, to explore the enduring significance of Universal Serial Bus (USB) portable flash drives. In the article, we develop the concept of ‘liminoid media’ as a way of coming to terms with continued use, and complications of use. Our understanding of this term is inspired by the seminal anthropological writings of Victor Turner ( pace Arnold van Gennep), more recent scholarship applying liminality to media studies and debates within media theory concerning the status of old and new media (where it has been argued, among other things, that media are always in transition rather than part of a strict old–new binary). Against this backdrop, we employ ‘liminoid media’ as a way of making critical sense of the ‘betwixt and between’ status of USB portable flash drives – their ongoing ‘suspendedness’ – and the complicated tensions that characterise participant use of these devices. For our participants, USBs are understood as fulfilling a compromise between emergent practices of cloud computing and more established forms of centralised data storage; they are understood as temporary data storage devices that are often used in semi-permanent ways to protect against data loss; they are seen as ephemeral devices that are rarely disposed of. USBs are also ‘ritualised’ insofar as they frequently become intimate, aestheticised everyday objects; yet, accompanying this ritualised ‘suspendedness’ are certain forms of risk and danger – of obsolescence, of data loss, of device failure, and so on. USBs, in short, occupy an essential if complicated position in people’s contemporary data storage practices. Examining USBs, and the practices of use that surround them, we argue, provides insight into current (and always ongoing) changes in the media environment, and demonstrates the extent to which liminoid media are contemporary in use.

This research is conducted to build portable spectroscopy optic with Android and desktop applications. Portable spectroscopy optic consists of Arduino Micro, Nextion Liquid Crystal Display (LCD), 2 pieces Light Emitting Diodes (LED), servo motor, diffraction grating (600 lines/mm), 2 pieces photodiodes, Bluetooth HC-05, and SD Card Reader Writer. Android and desktop applications realized by using Qt IDE. Spectroscopy testing is done using polymers with color red, green, and blue. The result of polymers sample testing shows that the spectrum with same wavelength range as the sample color will be passed, while other wavelengths will be absorbed. The device has been able to measure absorption of sample. On testing restore the test results to the SD card produces file with size about 2 kB. Device uses battery with capacity 3000 mAh and can be actively sustainable during 3 hours 31 minutes. Testing of communication Android and desktop applications with spectroscopy is done using bluetooth and Universal Serial Bus (USB) cable. The result of application testing are already able to send and receive data from spectroscopy.

Full textAbstract:
This paper describes the development of Phollower—an autonomous mobile robot intended to perform various logistical tasks in both industrial and civil environments. Phollower is equipped with the latest types of industrial components and sensors. It also employs advanced embedded navigation and localization software to create its own virtual maps and thereby to navigate autonomously within the mapped area. The whole development process has been focused on building a device that meets European safety standards. Phollower is a universal mobile platform that can be quickly expanded with specialized add-ons. A germicidal add-on for disinfection of indoor areas using UV-C light is described as a technology that helps to battle with the ongoing COVID-19 pandemic crisis. The hardware topology combined with the proposed open Programmable Logic Controller (PLC) code and open-Powerlink communication bus creates a unique and easily extendable robot platform.

Full textAbstract:
This paper demonstrates a route selection mechanism on a testbed with heterogeneous device-to-device (D2D) wireless communication for a 5G network scenario. The source node receives information about the primary users’ (PUs’) (or licensed users’) activities and available routes from the macrocell base station (or a central controller) and makes a decision to select a multihop route to the destination node. The source node from small cells can either choose: (a) a route with direct communication with the macrocell base station to improve the route performance; or (b) a route with D2D communication among nodes in the small cells to offload traffic from the macrocell to improve spectrum efficiency. The selected D2D route has the least PUs’ activities. The route selection mechanism is investigated on our testbed that helps to improve the accuracy of network performance measurement. In traditional testbeds, each node (e.g., Universal Software Radio Peripheral (USRP) that serves as the front-end communication block) is connected to a single processing unit (e.g., a personal computer) via a switch using cables. In our testbed, each USRP node is connected to a separate processing unit, i.e., raspberry Pi3 B+ (or RP3), which offers three main advantages: (a) control messages and data packets are exchanged via the wireless medium; (b) separate processing units make decisions in a distributed and heterogeneous manner; and (c) the nodes are placed further apart from one another. Therefore, in the investigation of our route selection scheme, the response delay of control message exchange and the packet loss caused by the operating environment (e.g., ambient noise) are implied in our end-to-end delay and packet delivery ratio measurement. Our results show an increase of end-to-end delay and a decrease of packet delivery ratio due to the transmission of control messages and data packets in the wireless medium in the presence of the dynamic PUs’ activities. Furthermore, D2D communication can offload 25% to 75% traffic from macrocell base station to small cells.
