Development of information technologies, cryptocurrencies and technology of distributed networks has caused the appearance of smart con- tracts as new types of civil contract. They have been widely used in recent years in such areas as initial coins offering (ICO), financial sector, inter- national trade and public services. At the same time the legal status and legal regulation of smart contracts are uncertain. These uncertainties cause many legal risks of smart-contractsutilization. The purpose of this article is to find out the conception of smart contract as a form of civil contract, to research its legal status and legal regula- tion issues and to develop proposals for the improvement of legal regulation of smart contracts and cryptocurrencies in Ukraine. By its legal nature a smart contract is a digital form of a civil contract realized in programming code automatically executed in a distributed network. Like a civil contract, smart contract has such elements as parties, subject and essential terms of the contract. The legal force of a smart contract depends on whether it includes the fundamental features of a civil contact, such as evidence that parties have intention to create legal relations, understandabil- ity of contract conditions and possibility to perform the terms of the contract under duress. The main advantages of a smart contract are its ability to significantly accelerate and reduce costs of the transaction and guarantee the fulfillment of contract terms regardless of the contractual parties' and third parties' will. The main risks of a smart contract are uncertainty of legal status of a smart contract and cryptocurrencies as a means of payment, complexity of expressing the contact terms in a mathematical algorithm, risk of software bugs and hacking attack. To solve the problems of legal regulation of smart contracts in Ukraine it is necessary to change the legislation in order to settle the legal status of cryptocurrencies and recognize a smart contract as a form of a civil contract. It is necessary to identify parties of the smart contract, confirm their agreement on the terms of the smart contract by using digital electronic signature. A smart contract should be supplemented by text application containing the es- sential terms of the contract which will have legal force in trail. It is necessary to implement blockchain technology in the state registers and pro- vide legal ability to make adjustments in the registers automatically for the performance of smartcontracts.

The world is facing a dangerous pandemic and it is a transmissible virus that infects people who came in contact with the infected person and with the things used by them. Many industries see huge economic losses, and businesses are going ruined. Although, unlock process is started still many industries facing problems due to the increasing rate of Covid positive patients, it is not possible to close working after the detection of individual positive employees. Also, it is difficult to find contacted employees with Covid positive employees. .It became a challenging task to find out how many people came in contact with the infected people. So, to make this process somehow easy we have designed a small device. In this paper, we have described the smart pendent a small device that helps to detect how many people come in contact with the coronavirus infected person. It is a wearable RF device in the form factor of a Pendant, suitable for powering a smart Rf device. An experimental comparison between multistage Cockcroft-Walton and Dickson RF-DC converters shows that the Dickson topology offers higher efficiency at high input power, whereas the Cockcroft- Walton converter performs better for low input power. The pendant can produce up to 23.2 µW at 10.4 m from a commercial isotropic 3 W RF power transmitter.

In order to improve comfort of smart garment, rigid electronic boards can be replaced with textile circuits, which use conductive yarns. When one tries to improve wearing comfort, often the most problematic items turn to be connection points of the electronic circuitry. The aim of this research is to determine behaviour of conductive yarns after they have been sewn into textile material, as well as to determine their suitability for the intended applications. In order to determine the quality of a conductive connective seams resistance has been measured (in Ω) under the influence of various variable factors: type of yarn, length of stitch, number of layers, type of seam. Besides that seam durability tests were carried, which show resistance changes over time and after washing.

Recent advances in smart contact lenses are essential to the realization of medical applications and vision imaging for augmented reality through wireless communication systems. However, previous research on smart contact lenses has been driven by a wired system or wireless power transfer with temporal and spatial restrictions, which can limit their continuous use and require energy storage devices. Also, the rigidity, heat, and large sizes of conventional batteries are not suitable for the soft, smart contact lens. Here, we describe a human pilot trial of a soft, smart contact lens with a wirelessly rechargeable, solid-state supercapacitor for continuous operation. After printing the supercapacitor, all device components (antenna, rectifier, and light-emitting diode) are fully integrated with stretchable structures for this soft lens without obstructing vision. The good reliability against thermal and electromagnetic radiations and the results of the in vivo tests provide the substantial promise of future smart contact lenses.

A smart contact lens can be used as an excellent interface between the human body and an electronic device for wearable healthcare applications. Despite wide investigations of smart contact lenses for diagnostic applications, there has been no report on electrically controlled drug delivery in combination with real-time biometric analysis. Here, we developed smart contact lenses for both continuous glucose monitoring and treatment of diabetic retinopathy. The smart contact lens device, built on a biocompatible polymer, contains ultrathin, flexible electrical circuits and a microcontroller chip for real-time electrochemical biosensing, on-demand controlled drug delivery, wireless power management, and data communication. In diabetic rabbit models, we could measure tear glucose levels to be validated by the conventional invasive blood glucose tests and trigger drugs to be released from reservoirs for treating diabetic retinopathy. Together, we successfully demonstrated the feasibility of smart contact lenses for noninvasive and continuous diabetic diagnosis and diabetic retinopathy therapy.

Vulnerabilities of smart contract are certainly one of the limiting factors for wider adoption of blockchain technology. Smart contracts written in Solidity language are considered due to common adoption of the Ethereum blockchain platform. Despite its popularity, the semantics of the language is not completely documented and relies on implicit mechanisms not publicly available and as such vulnerable to possible attacks. In addition, creating formal semantics for the higher-level language provides support to veriﬁcation mechanisms. In this paper, a novel approach to smart contact verification is presented that uses ontologies in order to leverage semantic annotations of the smart contract source code combined with semantic representation of domain-specific aspects. The following aspects of smart contracts, apart from source code are taken into consideration for verification: business logic, domain knowledge, run-time state changes and expert knowledge about vulnerabilities. Main advantages of the proposed verification approach are platform independence and extendability.

Abstract: In the aftermath of the coronavirus infection (COVID-19), contact with people has become an important risk factor. It is widely believed that the risk of spreading the virus increases with the number of people in contact with other objects or people. According to the World Health Organization (WHO), high fever and heart palpitations are the two most common symptoms of COVID-19. It is also recommended to wash your hands frequently and use an appropriate mask. That's why our project is trying to create a system that checks the body temperature, mask and heart rate of people entering the facility to make sure they are safe. Also, checks if the mask is worn correctly. Hence through our project we are trying to build a system that will make sure you are protected. Immediately after that, a non-contact disinfectant is provided which guarantees minimal contact between the person and the system. Keywords: COVID19, Open Source Computer Vision, TensorFlow, mask detection, temperature sensing, pulse detection, contactless hand sanitization.

In this paper, we demonstrate the first attempt of encapsulating a flexible micro battery into a contact lens to implement an eye-tracker. The paper discusses how to scale the battery to power various circuits embedded in the contact lens, such as ASIC, photodiodes, etc., as well as how to combine the battery with external harvested energy sources. The fabricated ring battery has a surface area of 0.75 cm2 yielding an areal capacity of 43 µAh·cm−2 at 20C. Based on simulated 0.35-µm CMOS ASIC power consumption, this value is large enough to allow powering the ASIC for 3 minutes. The functioning of the micro battery is demonstrated by powering an orange LED.

Rapid diagnosis and screening of diseases have become increasingly important in predictive and preventive medicine as they improve patient treatment strategies and reduce cost as well as burden on our healthcare system. In this regard, wearable devices are emerging as effective and reliable point-of-care diagnostics that can allow users to monitor their health at home. These wrist-worn, head-mounted, smart-textile, or smart-patches devices can offer valuable information on the conditions of patients as a non-invasive form of monitoring. However, they are significantly limited in monitoring physiological signals and biomechanics, and, mostly, rely on the physical attributes. Recently, developed wearable devices utilize body fluids, such as sweat, saliva, or skin interstitial fluid, and electrochemical interactions to allow continuous physiological condition and disease monitoring for users. Among them, tear fluid has been widely utilized in the investigation of ocular diseases, diabetes, and even cancers, because of its easy accessibility, lower complexity, and minimal invasiveness. By determining the concentration change of analytes within the tear fluid, it would be possible to identify disease progression and allow patient-oriented therapies. Considering the emerging trend of tear-based biosensing technology, this review article aims to focus on an overview of the tear fluid as a detection medium for certain diseases, such as ocular disorders, diabetes, and cancer. In addition, the rise and application of minimally invasive detection and monitoring via integrated contact lens biosensors will also be addressed, in regards to their practicality and current developmental progress.

<p class="0abstract">In recent years, electronic money facilities are increasingly diverse. It may replace conventional payments. The use of physical money can be diminished by utilizing digital money, which is realized by smartphone apps, bar codes, smart cards, and so on. The types of smart cards used also vary, and it can be divided into two methods, i.e., with contacts and without contact. In this work, we develop electronic transaction devices using dual interfaces: contact and contactless smart cards. As computational processing, we employ the Raspberry Pi 3 Model 3. It has a high processing speed, large memory, and small size. Hence our system enables to compact in a portable box. The features offered on our transaction device are as follows: transaction menu, balance check menu, payment menu, and top up menu. Also, we provide a device transaction connection to the printer. Therefore, proof of transactions can be printed out easily. The device developed also provides a touch panel display to display the transaction menu.</p>

Street light failure has become a major problem in cities nowadays. As the failure reports are sent very rare to government, these failures are checked only if a higher involvement action takes place. Monitoring of street lights and controlling is of utmost importance in developing country like India. Moreover, in today’s world, power saving is very important and difficult. Though there are many power generation methods, it has become very difficult due to insufficient resources. Considering this as a problem, this project is developed to send accurate location of fuse blown street light to a contact number (if government number provided). When a Street light doesn’t glow even after it is powered ON, the light detector circuit detects which is immediately sent to an Intel® Edison processor which processes the information. A GSM Module is attached to it, which sends the location of the blown fuse street light to the respective contact number.

Despite various approaches to immunoassay and chromatography for monitoring cortisol concentrations, conventional methods require bulky external equipment, which limits their use as mobile health care systems. Here, we describe a human pilot trial of a soft, smart contact lens for real-time detection of the cortisol concentration in tears using a smartphone. A cortisol sensor formed using a graphene field-effect transistor can measure cortisol concentration with a detection limit of 10 pg/ml, which is low enough to detect the cortisol concentration in human tears. In addition, this soft contact lens only requires the integration of this cortisol sensor with transparent antennas and wireless communication circuits to make a smartphone the only device needed to operate the lens remotely without obstructing the wearer’s view. Furthermore, in vivo tests using live rabbits and the human pilot experiment confirmed the good biocompatibility and reliability of this lens as a noninvasive, mobile health care solution.

Background Low infection and case-fatality rates have been thus far observed in Taiwan. One of the reasons for this major success is better use of big data analytics in efficient contact tracing and management and surveillance of those who require quarantine and isolation. Objective We present here a unique application of big data analytics among Taiwanese people who had contact with more than 3000 passengers that disembarked at Keelung harbor in Taiwan for a 1-day tour on January 31, 2020, 5 days before the outbreak of coronavirus disease (COVID-19) on the Diamond Princess cruise ship on February 5, 2020, after an index case was identified on January 20, 2020. Methods The smart contact tracing–based mobile sensor data, cross-validated by other big sensor surveillance data, were analyzed by the mobile geopositioning method and rapid analysis to identify 627,386 potential contact-persons. Information on self-monitoring and self-quarantine was provided via SMS, and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) tests were offered for symptomatic contacts. National Health Insurance claims big data were linked, to follow-up on the outcome related to COVID-19 among those who were hospitalized due to pneumonia and advised to undergo screening for SARS-CoV-2. Results As of February 29, a total of 67 contacts who were tested by reverse transcription–polymerase chain reaction were all negative and no confirmed COVID-19 cases were found. Less cases of respiratory syndrome and pneumonia were found after the follow-up of the contact population compared with the general population until March 10, 2020. Conclusions Big data analytics with smart contact tracing, automated alert messaging for self-restriction, and follow-up of the outcome related to COVID-19 using health insurance data could curtail the resources required for conventional epidemiological contact tracing.

Abstract A switchable contact lens prototype was fabricated and tested with integrated off the shelf electronic components to drive a liquid crystal (LC) active lens element. This prototype was capable of changing its focal power by an average of +1.9D, but a maximum of +3.2 ± 0.2D was also measured. Switchable focus contact lenses are intended to help restore functional near and intermediate vision accommodation to those suffering from presbyopia, an inevitable age-related eye condition. The custom poly-methyl-methacrylate contact lens substrates used in this prototype are equivalent to commercially available scleral contact lenses. It was discovered that more careful design considerations are needed when at least one of the substrates is <100 µm thick (which is needed for a final device). Without these design considerations, the switchable focal power of the lens is susceptible to change as the LC insert layer is able to flex. The prototype has an on-board electronics platform which was self-powered with a battery. Illuminating the electronics package with a 600 Hz infrared signal switched the device on, which passed an AC voltage to the electrodes of the contact lens, reorientating the director of the LC with an electric field. To our knowledge, this is the first demonstration of a battery powered and wirelessly triggered smart contact lens for the treatment of presbyopia.

In this study, a strain gauge sensor based on a change of contact or network structure between conductive materials was implemented using the handle-machine embroidery technique, and the variables (embroidery shape, embroidery distance, embroidery size, and implementation location) affecting its performance were studied. As a result of Experiment I on the structure of embroidery suitable for joint motion monitoring, the embroidery distance, rather than the embroidery size, was found to have a significant effect on the electric resistance changes caused by elongation. Based on the results of Experiment I, two types of zigzag embroideries, four types of embroideries with few contact points, and two types of embroideries with more contact points (all with short distances (2.0)) were selected for Experiment II (the dummy motion experiment). As a result of the dummy motion experiment, it was found that the locations of the suitable embroidered sensors for joint motion monitoring was the HJP (Hinge Joint Position) in the ‘types without a contact point’ (zigzag) and the LHJP (Lower Hinge Joint Position) in the ‘types with more contact points’. On the other hand, although there was no consistency among the ‘types with few contact points’, the resistance changes measured by the 2CP and 7CP embroidered sensors showed similar figures and patterns, and the HJP location was most suitable. The resistance changes measured by the 4CP and 6CP embroidered sensors exhibited no consistent patterns, but the LHJP locations were more suitable. These results indicate that the location of the HJP is suitable for measuring joint motion in the ‘type without a contact point’, and the location of the LHJP is suitable for measuring joint motion when the number of contact points exceeds a certain limit. Among them, the average resistance change of the 9CP sensor located at the LHJP was 40 Ω with the smallest standard deviation of less than 1, and it is thus considered to have the best performance among all the sensors.

This article has been prepared for the research purpose of identifying, disclosing, and justifying certain trends in the development of civil law and procedures in the context of the spread of smart contract practices and the expansion of their spheres of application. At the moment, there is no uniform approach to choosing an optimal form for the legal regulation of smart contracts within the system of contract law in modern legal systems or international law; meanwhile, globalization and the digitalization of the economy imply the growth of cross-border transactions. The emergence of smart contracts is due to the development of e-commerce, in which the parties’ interactions are carried out electronically instead of in physical exchanges or direct physical contact. Smart contracts gaining popularity in circulation are based on two interrelated elements: firstly, they eliminate a person’s direct participation in some or all cases of executing the agreement using an automated code designed for execution without reference to the intentions of the contracting parties after publication; secondly, they make use of decentralized blockchain technology, and also provide automatic code execution without any party’s potential intervention, so as to eliminate or reduce the self-control and third-party control of the commitment.This study examines the content, conclusion, validity, protection of rights and legitimate interests of the parties, interpretation, and legal nature of smart contracts. The research materials used foreign experience in resolving disputes from smart contracts on digital platforms (Kleros, JUR, Aragon Network Justice, OpenCourt, OpenBazaar), as well as domestic and foreign literature on smart contracts. This research has been prepared based on general (deduction, dialectical analysis, intersectoral relations of objects) and specialized (comparative-legal, economic-legal) methods of scientific experimentation.The authors conclude that there are no grounds for considering a smart contract as a new classification element of the system of contractual regulation (type or kind of contract). In addition, the analysis shows that the resolution of smart contract disputes through digital platforms remains radically uncertain, and currently is not creating obvious advantages in comparison with traditional judicial proceedings.

The article shows the features of innovative technologies in the development of document management of international trade. Blockchain is defined as the most stable, transparent and secure system. It allows businesses to accelerate the workflow and business operations associated with signing a contract, making payments and transferring information about the supply of goods or services to logistics services. We suggest using a smart contract as the main technology that can improve the system of building contractual relations between the parties to international trade. The article identifies the main problems on the way to using technology, as well as the benefits of using smart contracts. The study shows the ways of implementing technology in a business. The smart contact technology allows you to simplify the process of using a letter of credit as the main method of payment in international trade, as well as monitor cash flow, the circulation of documents and goods.

Abstract Ultrasonic welding is a common and indispensable technology in the packaging of power electronics. Typical applications are terminals and power contacts, e.g. in motor drive or inverter modules, as well as busbar connections. The process control requirements for welding power electronics connectors or bus bars, e.g. on batteries, are increasingly overlapping with requirements typical for heavy wire bonding. Smart ultrasonic welding is a new technology combining the force and ultrasonic power of conventional ultrasonic welding equipment with the flexibility, precision, speed and advanced process control features of wire bonding machines. This contribution discusses the characteristics of smart welding equipment and presents process results for two different smart welding applications. On the low power end, smart welding and wire bonding are compared in the production of cylindrical cell battery packs, using a 100 W ultrasound system and aluminium connectors. Towards the high power end, 3 × 1.2 mm2 copper leads are welded to DBC with a contact area of 3 × 3 mm2, using a 1.5 kW ultrasound system. Both applications demonstrate advantages of smart welding over conventional ultrasonic welding.

Smart technologies such as smart phones, iPad and Tablets are ubiquitous in today’s society. They possess increasing computing and storage potentials. Thus, emerging as a dominant computing platform for different kinds of end-users. However, these technological possibilities have not been fully explored for emergency situations where close relatives must be contacted. This paper therefore presents an Emergency Contact Recommendation Model (ECRM) that was implemented into an emergency contact recommendation system. An architectural based approach was employed to highlight the contribution this paper made to extant knowledge. The leveraged of the Dust miner algorithmic technique, the direct discriminative pattern mining, and the Bayesian Inference Network technique were used to formulate the ECRM. The ECRM was implemented using the Java development and android tool kit. The model demonstrated commendable capabilities - considering the foregoing techniques when compared with what obtains in literature- to make useful recommendation in emergency situation(s) after implementation. http://dx.doi.org/10.4314/njt.v36i124

A smart mannequin with the dimension of a standard female body was used for measuring garment pressure. Compression garments made from five kinds of elastic knitted fabrics which are purchased commercially. Results showed that the pressure distributions exhibited obvious differences were varied, and the elongation caused pressure variations among the specimens. This smart mannequin system provides a novel tool for evaluating the pressure performance of compression garments, and give reliable data for functional product development.

Objective. To visually compare the Nitinol “smart” stapes prosthesis to conventional manual crimping stapes pistons in temporal bone cadaver specimens. Main Outcome Measures. 10 otolaryngologists were given a photograph of the randomly ordered stapes pistons and asked to use the pictures to answer questions about each stapes piston. The answers to the survey were then recorded for analysis. Results. 8 of 9 Nitinol pistons were described as circular, and 3 of 9 manual crimped pistons were described as circular (P< .05). 6 of 9 Nitinol pistons were considered to be in contact with >66% of the incus and 3 of 9 to be in contact with 34–66% of the incus. 3 of 9 manually crimped pistons were considered to be in contact with >66% of the incus, 3 with 34–66% contact and 3 with less than 34% contact. Conclusions. The Nitinol “smart” stapes pistons were considered to provide a more circular and circumferential crimping and to have greater contact with the long process of the incus than conventional stapes pistons.

Introduction In recent years, electromyography (EMG) has been increasingly studied for wearable applications. Conventional gel electrodes for electrophysiological recordings have limited use in everyday applications such as prosthetic control or muscular therapy at home. This study investigates the efficacy and feasibility of dry-contact electrode materials employed in smart textiles for EMG recordings. Methods Dry-contact electrode materials were selected and implemented on textile substrates. Using these electrodes, EMG was recorded from the forearm of able-bodied subjects. 25% and 50% isometric maximum voluntary contractions were captured. A comparative investigation was performed against gel electrodes, assessing the effect of material properties on signal fidelity and strength compared. Results When isolating for electrode surface area and pressure, 31 of the 40 materials demonstrated strong positive correlations in their mean PSD with gel electrodes (r > 95, p < 0.001). The inclusion of ionic liquids in the material composition, and using raised or flat electrodes, did not demonstrate a significant effect in signal quality. Conclusions For EMG dry-contact electrodes, comparing the performance against gel electrodes for the application with the selected material is important. Other factors recommended to be studied are electrodes’ durability and long-term stability.

Abstract Timely identification of collision damage, especially in aging bridges, is critical for the safety of commuters. However, there is no efficient, cost-effective, in-situ technique to serve this purpose. Wave propagation-based structural health monitoring (SHM) using piezoelectric material is a promising alternative for remote sensing. To that end, this study aims to develop a wave propagation-based monitoring technique using surface-bonded smart piezoelectric modules (SPM) to determine the impact force, location, and projectile properties of low-velocity impacts on concrete panels. An impact source localization algorithm used in composite structures is adapted and simplified for concrete structures. This technique is validated using a combined experimental and numerical investigation, which shows good agreement with the actual impact source location. The impact force, projectile mass, and velocity are determined using a semi-theoretical-experimental technique based on Reed contact model. A special contact-SPM is fabricated and calibrated to determine the contact force at the impact location. The relationship between contact-SPM response and distributed-SPM response is determined using a drop-weight test with steel sphere. The peak contact force and contact duration are in good agreement with Reed contact model, although the latter overpredicts the given parameters. A simplified formula based on Reed contact model is used to inversely estimate the projectile velocity of a known mass and vice versa. Then, using the pre-calibrated data, the impact force, projectile properties, and impact force-time distribution are determined using the response of distributed-SPM system. The technique is validated using an arbitrary steel sphere mass. As demonstrated in the combined experimental, theoretical, and numerical study, the proposed surface-bonded SPM system is capable of effectively identifying low-velocity impact incidents on concrete structures, which could potentially facilitate inexpensive, in-situ, real-time condition assessment.

PurposePhysical gatherings at social events have been found as one of the main causes of COVID-19 transmission all over the world. Smartphone has been used for contact tracing by exchanging messages through Bluetooth signals. However, recent confirmed cases found in venues indicated that indirect transmission of the causative virus occurred, resulting from virus contamination of common objects, virus aerosolization in a confined space or spread from inadequate ventilation environment with no indication of human direct or close contact observed.Design/methodology/approachThis paper presents a novel cyber-physical architecture for spatial temporal analytics (iGather for short). Locations with time windows are modeled as digital chromosomes in cyberspace to represent human activity instances in the physical world.FindingsResults show that the high spatial temporal correlated but indirect tracing can be realized through the deployment of physical hardware and spatial temporal analytics including mobility and traceability analytics. iGather is tested and verified in different spatial temporal correlated cases. From a management perspective of mobilizing social capacity, the venue plays not only a promotion role in boosting the utilization rates but also a supervision-assisted role for keeping the venue in a safe and healthy situation.Social implicationsThis research is of particular significance when physical distancing measures are being relaxed with situations gradually become contained. iGather is able to help the general public to ease open questions: Is a venue safe enough? Is there anyone at a gathering at risk? What should one do when someone gets infected without raising privacy issues?Originality/valueThis study contributes to the existing literature by cyber-physical spatial temporal analytics to trace COVID-19 indirect contacts through digital chromosome, a representation of digital twin technology. Also, the authors have proposed a venue-oriented management perspective to resolve privacy-preserving and unitization rate concerns.

This paper describes the development of a new generation of magnetic contact. The development of this new generation of the magnetic contact is a part of the research activity of the security engineering laboratory. The new generation of magnetic contact is based on the Hall-Effect Sensor and microcontroller unit. Older magnetic contacts use a simple reed relay with only two states â€“ normally closed or normally opened. The combination of the Hall-Effect Sensor and microcontroller unit provides advanced possibilities such as a programmable level of magnetic field sensitivity, adding different communication modules, programmable inputs/outputs etc. The results of this paper explain proposal of the new generation of magnetic contact, which can be used not only as a part of intruder alarm systems but also as a part of smart homes and other autonomous systems. The content of the paper can be used for even deeper research and by security systems developers as well.
