Background.Despite a proliferation of phlebotomy devices with engineered sharps injury protection (ESIP), the impact of various winged device designs on blood splatter occurring during venipuncture procedures has not been explored.Objectives.To evaluate the potential for blood splatter of 6 designs of winged phlebotomy devices.Design.A laboratory-based device evaluation without human subjects, using a simulated patient venous system.Methods.We evaluated 18 winged phlebotomy devices of 6 device designs by Terumo, BD Vacutainer (2 designs), Greiner, Smith Medical, and Kendall (designated A-F, respectively). Scientific filters were positioned around the devices and weighed before and after venipuncture was performed. Visible blood on filters, exam gloves, and devices and measurable blood splatter were the primary units of analysis.Results.The percentages of devices and gloves with visible blood on them and filters with measurable blood splatter ranged from 0% to 20%. There was a statistically significant association between device design and visible blood on devices (P< .0001) and between device design and filters with measurable blood splatter (P< .0001), but not between device design and visible blood on gloves. A wide range of associations were demonstrated between device design and visible blood on gloves or devices and incidence of blood splatter.Conclusions.The results of this evaluation suggest that winged phlebotomy devices with ESIP may produce blood splatter during venipuncture. Reinforcing the importance of eye protection and developing a methodology to assess ocular exposure to blood splatter are major implications for healthcare personnel who use these devices. Future studies should focus on evaluating different designs of intravascular devices (intravenous catheters, other phlebotomy devices) for blood splatter.

From PDAs to cell phones to MP3 players, handheld electronic devices are ubiquitous. Human factors engineers and designers have a need to remain informed about advances in research on user interface design for this class of devices. This review provides human factors research summaries and research-based guidelines for the design of handheld devices. The major topics include anthropometry (fitting the device to the hand), input (types of device control and methods for data entry), output (display design), interaction design (one-handed use, scrolling, menu design, image manipulation, and using the mobile Web), and data sharing (among users, devices, and networks). Thus, this review covers the key aspects of the design of handheld devices, from the design of the physical form of the device through its hardware and software, including its behavior in networks.

<abstract> <p>Camera devices are being deployed everywhere. Cities, enterprises, and more and more smart homes are using camera devices. Fine-grained identification of devices brings an in-depth understanding of the characteristics of these devices. Identifying the device type helps secure the device safe. But, existing device identification methods have difficulty in distinguishing fine-grained types of devices. To address this challenge, we propose a fine-grained identification method based on the camera deviceso inherent features. First, feature selection is based on the coverage and differences of the inherent features type. Second, the features are classified according to their representation. A design feature similarity calculation strategy (FSCS) for each type of feature is established. Then the feature weights are determined based on feature entropy. Finally, we present a device similarity model based on the FSCS and feature weights. And we use this model to identify the fine-grained type of a target device. We have evaluated our method on Dahua and Hikvision camera devices. The experimental results show that we can identify the deviceos fine-grained type when some inherent feature values are missing. Even when the inherent feature pmissing rateq is 50%, the average accuracy still exceeds 80%.</p> </abstract>

As designers of mobile/media-rich devices continue to incorporate more features/functionality, the evolution of interfaces will become more complex. Meanwhile, users cognitive models must be aligned with new device capabilities and corresponding physical affordances. In this paper, the authors argue that based on HCI design theory, users approach objects by building mental models starting with physical appearance. Findings suggest that users who embrace a device’s multifunctionality are prevented from taking full advantage of an array of features due to an apparent cognitive constraint caused by a lack of physical controls. The authors submit that this problem stems from established mental models and past associated behaviors of both mobile and non-mobile interactive devices. In conclusion, users expressed a preference for immediate access and use of certain physical device controls within a multi-tasking environment, suggesting that as mobile computing becomes more prevalent, physical affordances in multifunctional devices may remain or increase in importance.

The objective of this systematic review is to analyze types of needle-free connectors and open systems and their effects on central line–associated bloodstream infection rates and other adverse outcomes through a research protocol consistent with the Preferred Reporting Items for Systematic Reviews’ recommendations. MEDLINE and Cochrane databases of systematic reviews were searched for relevant comparative studies published from January 2000 to September 2017. Eighteen studies compared central line–associated bloodstream infection (according to the Centers for Disease Control and Prevention/National Healthcare Safety Network definition), internal microbial contamination, occlusions, phlebitis, and other outcomes associated with needle-free connectors with a positive displacement device, negative displacement device, neutral displacement device, or three-way stopcock. Ten studies reported central line–associated bloodstream infection rates, which were lower with positive displacement devices versus negative displacement devices/neutral displacement devices (one study) and with negative displacement devices versus three-way stopcocks (three studies), but varied with different positive displacement device and negative displacement device/neutral displacement device designs (four studies). Seven studies reported internal microbial contamination rates, which were higher with three-way stopcocks versus negative displacement devices (two studies) and positive displacement devices (two studies), lower when positive displacement devices were used versus neutral displacement devices (one study), and varied with different types of negative displacement device (one study). Central line–associated bloodstream infection rates and most other outcomes analyzed were statistically significantly higher with three-way stopcocks (open devices) versus positive displacement device, negative displacement devices, and neutral displacement devices, but varied among closed device designs.

Abstract As the physical size of semiconductor devices continues to be aggressively scaled down, feedback field-effect transistors (FBFET) with a positive feedback mechanism among a few promising steep switching devices have received attention as next-generation switching devices. Conventional FBFETs have been studied to explore their device performance. However, this has been restricted to the case of single FBFET; basic circuit designs with FBFETs have not been investigated extensively. In this work, we propose an inverter circuit design with silicon-on-insulator (SOI) FBFETs; we verified this inverter design with mixed-mode technology computer-aided design simulation. The basic principles and mechanisms for designing FBFET inverter circuits are explained because their configuration is different from conventional inverters. In addition, the device parameters necessary to optimize circuit construction are introduced for logic device applications.

This paper proposes a method to ensure compatibility between physical devices for implementing a service design. The method supports the relaxation of strict implementation. It allows a set of compatible devices to be implemented instead of specifying specific devices in the service design. This paper’s main contribution is the formalization of device constraints using the device’s attributes and a method to check the compatibility between devices. The method’s characteristic is that a service designer can decide the level of strictness and abstractness of the design by adjusting the compatibility rate. We show the feasibility of the proposed method to achieve the goal of “Design Once, Provide Anywhere” with an application example. We also evaluated the quality of service of the implemented IoT service in a different environment using a platform called Elgar.

The performance of nanoelectronic and molecular electronic devices relies strongly on the employed functional units and their addressability, which is often a matter of appropriate interfaces and device design. Here, we compare two promising designs to build solid-state electronic devices utilizing the same functional unit. Optically addressable Ru-terpyridine complexes were incorporated in supramolecular wires or employed as ligands of gold nanoparticles and contacted by nanoelectrodes. The resulting small-area nanodevices were thoroughly electrically characterized as a function of temperature and light exposure. Differences in the resulting device conductance could be attributed to the device design and the respective transport mechanism, that is, thermally activated hopping conduction in the case of Ru-terpyridine wire devices or sequential tunneling in nanoparticle-based devices. Furthermore, the conductance switching of nanoparticle-based devices upon 530 nm irradiation was attributed to plasmon-induced metal-to-ligand charge transfer in the Ru-terpyridine complexes used as switching ligands. Finally, our results reveal a superior device performance of nanoparticle-based devices compared to molecular wire devices based on Ru-terpyridine complexes as functional units.

There have been some devices for rehabilitations of upper limb such as electronic device and mechanical device which is well-known as the passive one. These devices make the motion of upper limbs and stimulate the wrist, elbow, shoulder joints with muscles. This motion does by using the patient’s normal hand (left or right hand) and rotating the wounded hand’s wrist to be recovered by the clockwise or counterclockwise with some angles. Electronic devices for upper limb rehabilitation have the advantage that the electronic ones can supply various rehabilitation exercises to the patients. However these electronic devices include relatively expensive components such as various kinds of sensors, controllers, and display device. Therefore, the prices of implementation are too expensive. On the other hand, in conventional passive upper limb rehabilitation, the patients grasp the both handles without any mechanical links. It does not supply proper rehabilitation motion because the normal hand does not supply the rehabilitation motion to hand to be recovered. So to speak, this is not proper to patients with the one hands trouble such as hemiplegic patients, by himself without the aids of any other persons. In this paper, we describe the mechanical device for rehabilitations of wrist and the proposed handles to be attached in this mechanical device. This proposed handles can generate the three angle motion of wrist such as the roll, pitch and yaw. This proposed device has some features that this device can be implemented with lower costs than electronic devices and can be used whatever the wounded hand is right or left by selecting the lever. Further, when the patient has the rehabilitation exercise intent, the patients can easily use the proposed upper limb rehabilitation devices without the aid of the rehabilitation therapist the energy source is the normal hands of the patients.

In the last few years there has been an incredible rise in the amount of game applications available for the latest generation of mobile platforms. An increasing amount of developers and companies are starting to invest more heavily in producing for this growing market. This report investigates some of the challenges faced when developing these games, with the focus on the genre turn based strategy games. The main areas that are explored are the time of a session with the device, the touchscreen control, the hardware and graphics, and finally the user interface. To accomplish this, three methods were used: creating a survey, testing successful game titles within the genre, and investigating various sources on the internet. The findings suggest that rounds should be possible to complete in considerably less time than a minute. Also, people seems to have no preference in the way a game is controlled as long as the controls fits the game well. In regards to graphics and hardware, it was shown that people do not see 3D graphics as a requirement and developers should not prioritize it over other aspects of the game. As for the user interface, amongst other conclusions, developers should aim to keep clickable items the same size across screen sizes instead of downscaling them for smaller devices 1
De senaste åren har antalet spelapplikationer för den senaste generationen mobila platformar ökat dramatiskt. Ett växande antal utvecklare och företag har börjat satsa mer och mer på att producera material till denna uppåtgående marknad. Den här rapporten utforskar några av de utmaningar som man ställs inför när man utvecklar spel till den mobila marknaden, med fokus på genren turbaserade strategispel. De områden som utreds i detalj är tiden för en spelsession, kontroll med pekskärmen, hårdvara och grafik, samt användargränssnitt. Tre metoder användes för att genomföra detta: skapa en enkät, testa inom genren framgångsrika spel, samt undersöka diverse källor på internet. Resultaten pekar mot att rundor bör vara möjliga att avsluta inom en minut. Det verkar också som att användare inte har några preferenser när det gäller hur ett spel ska kontrolleras så länge som kontrollerna passar spelet. Angående grafik och hårdvara så svarade enkättagare att 3D grafik inte är ett krav, utvecklare bör därför inte prioritera 3D grafik över andra delar av spelet. Utvecklare av användargränsnitt bör, bland annat, se till att clickbara ting på skärmen inte nerskalas på mindre skärmar utan håller en konsekvent storlek mellan olika skärmstorlekar.

Designing touch screen devices includes many variables off how to address design issues in the best possible way. The design includes what type of touch interaction method is to be used, how the interface is to be designed and in which context it will be used. The problematic issue that has to be dealt with is how the designer must put together all these parameters into one final product. This paper presents the case of re-designing a touch screen bedside monitor, a device used in hospitals to observe the vital signs of patients. The design solution presented deals with the issues of how the device was designed to suit the users and environment of a hospital. A contextual inquiry showed the many constraints and standards that had to be met and how they shaped the design solution. Earlier work shows the different methods for touch interaction, interface design and feedback that can be applied for touch screen devices. The resulting design is discussed in relation to the different ways of creating touch screen interfaces, and an example of a work method is presented in the end of the paper on how to design for contextual touch screen devises.

NASA missions require innovative power electronics system and component solutions with long life capability, high radiation tolerance, low mass and volume, and high reliability in space environments. Presently vertical double-diffused MOSFETs (VDMOS) are the most widely used power switching device for space power systems. It is proposed that a new lateral double-diffused MOSFET (LDMOS) designed at UCF can offer improvements in total dose and single event radiation hardness, switching performance, development and manufacturing costs, and total mass of power electronics systems. Availability of a hardened fast-switching power MOSFET will allow space-borne power electronics to approach the current level of terrestrial technology, thereby facilitating the use of more modern digital electronic systems in space. It is believed that the use of a p+/p-epi starting material for the LDMOS will offer better hardness against single-event burnout (SEB) and single-event gate rupture (SEGR) when compared to vertical devices fabricated on an n+/n-epi material. By placing a source contact on the bottom-side of the p+ substrate, much of the hole current generated by a heavy ion strike will flow away from the dielectric gate, thereby reducing electrical stress on the gate and decreasing the likelihood of SEGR. Similarly, the device is hardened against SEB by the redirection of hole current away from the base of the device's parasitic bipolar transistor. Total dose hardness is achieved by the use of a standard complementary metal-oxide semiconductor (CMOS) process that has shown proven hardness against total dose radiation effects.

The lymphatic system has three primary roles: transporting lipids, transporting immune cells, and maintaining fluid balance. Each one of these roles are influenced by the presence of flow. Inflammation increases lymph flow, lipid uptake is enhanced by flow, cancer cell migration increases in the presence of flow, and lymphatic permeability and lymphatic contractility respond to changes in flow. Flow is very important to lymphatic function, and yet, there are no in vitro models that incorporate both luminal (flow along cell lumen) and transmural (flow through cell lumina) flow for lymphatics. To address this need, a microfluidic device has been developed that can incorporate both of these types of flow. This is achieved by driving flow through a channel which creates a pressure gradient that drives fluid through a porous membrane into an adjacent channel. Following several design iterations, the device can be easily fabricated, imaged, and cells can grow and survive in it. Permeability experiments have been performed in static and flow, 0.175 mL/min (0.5 dyne/cm²), cases. The effective permeability of dextran in the static and flow cases was calculated to be 0.0083 μm/s and 2.05 μm/s respectively. While the effective permeability of bodipy in the static and flow cases was calculated to be 0.0053 μm/s and 2.57 μm/s respectively. The static values are similar to values obtained in a transwell study by Dixon et al. As mentioned, lipid uptake is increased in the presence of flow and these numbers suggest the same. In addition to permeability studies, experiments were performed with cancer cells suspended in a collagen gel. Two image processing techniques were used to quantify cancer cell migration. The first technique was used to calculate the number of cells present at the beginning of the experiment and the number of cells that were ever present during the experiment in that particular z slice. The static case yielded a cell flux of 15 additional cells. While the two flow cases, within interstitial flow range, had a flux of 24 and 40 cells. This suggests that flow increases migration in cancer cells and is in agreement with the literature. The second technique was used to show that the cells in the static and flow cases are similarly motile, but the flow case is more directed in the z direction towards the membrane. The future work for this device is quite extensive, but a strong foundation centered around basic capabilities like inducing flow, seeding cells, and imaging has been formed.

Reinforcement Learning is an increasingly popular area of Artificial Intelligence. The applications of this learning paradigm are many, but its application in mobile computing is in its infancy. This study aims to provide an overview of current Reinforcement Learning applications on mobile devices, as well as to introduce a new framework for iOS devices: Swift-RL Lib. This new Swift package allows developers to easily support and integrate two of the most common RL algorithms, Q-Learning and Deep Q-Network, in a fully customizable environment. All processes are performed on the device, without any need for remote computation. The framework was tested in different settings and evaluated through several use cases. Through an in-depth performance analysis, we show that the platform provides effective and efficient support for Reinforcement Learning for mobile applications.

Efficient engineering design and development of high precision and reliable surgical simulators, like haptic devices for surgical training benefits from model-based and simulation driven design. The complexity of the design space, multi-domains, multicriteria requirements and multi-physics character of the behavior of such a product ask for a model based systematic approach for creating and validating compact and computationally efficient simulation models to be used for the design process.The research presented in this thesis describes a model-based design approach towards the design of haptic devices for simulation of surgical procedures, in case of hard tissues such as bone or teeth milling. The proposed approach is applied to a new haptic device based on TAU configuration.The main contributions of this thesis are: Development and verification of kinematic and dynamic models of the TAU haptic device. Multi-objective optimization (MOO) approach for optimum design of the TAU haptic device by optimizing kinematic performance indices, like workspace volume, kinematic isotropy and torque requirement of actuators.  A methodology for creating an analytical and compact model of the quasi-static stiffness of haptic devices, which considers the stiffness of; actuation system;flexible links and passive joints.

Microfluidics is a relatively new and, with an estimation of the market for these devices exceeding $3 billion in 2014, it is considered a profitable domain. Constant development of new technologies and growing demand for more versatile products cause increasing complexity in this area. To address this, the current trends for the domain include automation, standardisation and customisation. At the same time, the society is moving from product types offering to services. Due to the customisation trend this transition appears beneficial for microfluidics. Taking advantage of these opportunities, an investigation of microfluidic design has been undertaken to address the issues at their origins. The literature review showed a lack of a general design methodology applicable for all microfluidic devices, identified existing approaches as technology driven and the domain as unique in terms of design. Also, it highlighted a number of automation and standardisation attempts in the area. In addition, microfluidics shows limited customer and service-orientation. Meanwhile, an investigation of complexity and its implications in microfluidics narrowed the study to sub-section interactions, which allowed standardisation and automation without compromising customisation. In response to these gaps, an aim of the research is to develop a guideline for service- oriented design of microfluidic devices that can deal with sub-section interactions. This research reviews: existing methodologies for design in micro-scale, their applicability to the domain, microfluidic practitioners’ approach to design, state of service-thinking and services in the area and how sub-section interactions are dealt with for these devices. The developed guideline and design enablers present a proposal for a general process for the design of microfluidics. The solution attempts to tackle the issue of sub- section interactions and brings the domain one step towards an ‘experience economy’ by incorporating service-considerations into the design process. The usefulness of this contribution has been confirmed by a variety of methods and numerous sources including experts in the field.

Abstract Recently, many vision disorders such as myopia and hyperopia can be corrected via LASIK refractive surgery. Based on the photo-ablation effect of UV-laser pulses (at 193 nm for most commercial devices), the shape of the treated cornea is modified in order to regain the normal vision capability. In laser corneal reshaping process, the laser parameters must be adjusted to maintain the desired photo-ablation effect. Moreover, the design of the employed device plays an important role in performing successful surgeries with optimum results. However, the commercial devices are designed for specific operations with a limited access to their optical system and software. Besides, these devices are not available for research or training. Consequently, we provide a low-cost and easy-to-use ablation device that can be utilized as an educational, research, and training tool for the specialists in corneal reshaping and related procedures at universities, research institutes, or medical centers. The device has a special opening to enable entry of external laser source for any desired experimental investigations. Moreover, the binocular in commercial devices is replaced by live view screen to decrease the device’s cost. There are no access limitations to the software or the optical system of the proposed device.

The time required to get a device to market is critical to a successful design, development, and manufacturing process [1]. Achieving status of the first device to market is often a priority for manufacturers and developers. Upon market introduction, it is well known that device performance must meet at least minimum standards in order to provide consumer satisfaction and be a successful product to prevent competitive devices from taking over the market [1]. However, if a design only meets minimum expectations, it may struggle to maintain market control. This demonstrates the tradeoffs of speed-to-market and performance, for which optimization has not been clearly defined [2]. Product performance and usability can be designed in, evaluated and enhanced in order to avoid user errors and achieve optimal profitability. For medical devices, clinical trials are a key step in preparing to take a device to market. Clinical trials can allow for analyses of the effectiveness of the device in the patient care process. For wearable medical devices, patient usability is crucial to patient adherence and safety since the device will be operated by non-medically trained individuals [3,4]. Without adequate usability, adherence and continuity of care are greatly reduced which will reduce the overall effectiveness of the device [5,6]. Human factors principles can best be incorporated in the design process to improve the usability of medical devices and patient safety [5,6,7], specifically for those used in telemedicine [4] and cardiovascular treatment [3]. The objective of this project was to evaluate a telemedicine heart rate monitoring device for patient usability in order to improve the next device’s performance and lead to greater patient adherence for the current version via an improved user manual.

Lower limb length discrepancy (LLD), defined by unequal length of paired lower limbs, contributes to lower back pain, osteoarthritis of the hip, and stress fractures [1–3]. The Center for Disease Control and Prevention estimated that there were approximately 700 children born with LLD each year in US [4]. Patients may receive distraction osteogenesis treatment, in which an osteotomy is performed on the shorter limb, and mechanical force is applied to gradually distract the two halves of the bone during the healing process. This stretches the bone callus during healing to achieve desired limb length upon callus consolidation [5]. The current correction devices are external fixators that leave unsightly scars and are prone to infection [6]. While recently developed intramedullary devices address many of the persistent issues with external lengthening devices, size limitations and potential damage to the bone growth plates make them impractical for use in children [7, 8]. The proposed research addresses an unmet need by developing a novel implantable extramedullary device for LLD correction that is targeted for pediatric use. The device will be implantable, submuscular, and fixed to the outside surface of the bone (extramedullary), thus allowing for use in children without concern for injury to the growth plates. The device’s function will be similar to an external fixator; however, it will not require exposed hardware, which increases risk of infection, or muscle penetration from the pins, which causes pain. Additionally, the device incorporates real-time control of the distraction rate, reducing the risk of complications arising from fixed rate distraction such as premature consolidation and non-union of the callus. [9–11]. The investigators of this study have previously designed and constructed a distraction mechanism prototype and test frame [10]. The current study aims to validate the real-time controller of the prototype.

Abstract There are few medical devices currently utilized that have not had, at the very least, a second iteration. Medical device companies continually strive to improve their product to make it the best on the market. Medical devices are often optimized by defining the size of the device, making it more efficient and/or improving the device to tissue interface. Using the capabilities of the Visible Heart® Laboratories various cardiac devices can be implanted in reanimated swine and human hearts for the assessment of the various aforementioned parameters. After the implantation of these devices and assessment in functional anatomies, specimens were perfusion-fixed and then a micro-CT scanner was utilized to take high-resolution scans of the resultant device and tissue interfaces. These scans are used to generate high-resolution (∼20 microns) 3D models of the numerous implanted devices, measurement analyses, device simulations, and the creation of virtual reality scenes. All can then be used for detailed visual analyses. These abilities to render high-resolution models will allow medical device designers to closely evaluate their designs, in order to optimize their next iterations.

The increasing complexity of the medical regulatory environment and the inherent complexity of medical devices, especially due to the increased use of connected devices and embedded control software, impose adoption of new methods and tools for the system design, safety and security analyses. In this paper, we propose a method and an associated toolchain to couple model-based system engineering and safety/security analyses at the design phase of medical devices. The method is compliant with ANSI/AAMI/ISO TIR57 safety and security guidance, and compatible with INCOSE Biomedical-Healthcare Model-Based Systems Engineering works. The toolchain is based on a system architecture modelling tool and supports medical device domain specific reference architecture, as well as tools for safety and security risk analyses. The proposed method and toolchain are illustrated by considering a RGB’s TOF-CUFF monitor device analyzed in the scope of the AQUAS project as a medical device use case.

Patients are frequently prescribed a medication that must be administered either by a nasal spray, an inhaler, or a self-injection device. These devices are classified as combination devices by the Food and Drug Administration (FDA) and the Medical Device Regulations (MDR). However, there has been an issue of who and how do these patients get trained. It has long been the stance of the pharmaceutical companies they will not provide training because they provide an Information for Use (IFU) and/or a demo on their website. The issues with either of these means is that neither the FDA, nor the MDR permit them as mitigation for use errors. And, in human factors testing there are considerable numbers of use errors when patients attempt to use the devices.
