For design of automotive airbag electronic control units (AB ECU), it is essential to have a validated and reliable finite element (FE) simulation model in place in order to allow already in an early design stage for the accurate prediction of the ECU’s structural vibration behavior. A “bottom-up” approach which described in the ASME guide for verification and validation (ASME V&V 10-2006) is applied for the validation of the AB ECU simulation model. The AB ECU is decomposed into different assembly level. Single printed circuit board (PCB) is the lowest elementary component level. In the PCB level simulation and validation, the influence of in-plane pre-stress on PCB’s transverse vibration characteristic has been encountered, but it has been found out that the source of the in-plane pre-stress can not be explained by classical beam/plate theory. Analysis and simulation for PCB fixation reveals that the fundamental source of the in-plane pre-stress is structure’s geometric nonlinearity.

Research Procedure

Public spaces such as malls and entertainment venues have been visited by many people. This opportunity is used by industries engaged in the service sector to make a profit. Not a few agencies have created jobs to recruit employees in the field of promotional services. Promotion services work in the informal sector with the skills required by agencies to recruit women as sales promotions. SPG is used as a shortcut for some women to get a job. Women have a gentle attitude and are good at seducing with their physical capital, beautiful faces and eloquence in offering products to customers. SPG is used as the main job for women to make it easier to earn money. Most of the women who only go to school until they finish Senior High School (SMA) or Vocational High School (SMK) choose to work as SPGs. This job does not require high skills, only with a beautiful physique and face. This gives the view that the body and face are working capital as an SPG. The company benefits more from the SPG because it is seen as being able to boost product sales. In this study, the type of research used is a qualitative approach, namely "a research procedure that produces descriptive data in the form of writing and behavior that can be observed from the subject itself. The results of this study are 1) The concept of the body as a commodity is a common symptom in Makassar City. The body is likened to a commodity that has a selling value. As a commodity, the body can be converted just as the concept of the body is physical capital which can be converted into economic, cultural and social capital; 2) Some people view the SPG profession as a negative profession. because seen from the symbols attached to the SPG, for example, from wearing sexy clothes, make-up, to more aggressive and coercive verbal language when offering products and also the profession of SPG is a profession that only relies on beauty; 3) Negative stereotypes have been embedded in some societies so that what the general public perceives about SPG is almost the same.

The monitoring of Na+ ions distributed in the body has been indirectly calculated by the detection of Na+ ions in urine. We fabricated a two–dimensional (2D) Na+ ion sensor using a graphene ion–sensitive field–effect transistor (G–ISFET) and used fluorinated graphene as a reference electrode (FG–RE). We integrated G–ISFET and FG on a printed circuit board (PCB) designed in the form of a secure digital (SD) card to fabricate a disposable Na+ ion sensor. The sensitivity of the PCB tip to Na+ ions was determined to be −55.4 mV/dec. The sensor exhibited good linearity despite the presence of interfering ions in the buffer solution. We expanded the evaluation of the PCB tip to real human patient urine samples. The PCB tip exhibited a sensitivity of −0.36 mV/mM and linearly detected Na+ ions in human patient urine without any dilution process. We expect that G–ISFET with FG–RE can be used to realize a disposable Na+ ion sensor by serving as an alternative to Ag/AgCl reference electrodes.

Uric acid, as the terminal product of purine metabolism in the body, is an important marker of many diseases. Uric acid is abundant in saliva, offering the possibility of its non-invasive detection. However, it is sensitive to interference in saliva by a variety of factors. A reliable method of processing saliva is centrifugation (CF), but the cost and size of equipment limit its use in everyday life. In this study, a novel portable salivary-sensing system (PSSS) with integrated suction filtration (SF) and temperature insulation was proposed to obtain more accurate salivary uric acid levels through a simple procedure. The PSSS includes a saliva container, a high-sensitive uric acid sensor (UAS), an accompanying printed circuit board (PCB), and a mobile application. The responses produced by the UAS presents excellent linearity (4.6 μA/mM with R2 = 0.9964), selectivity, reproducibility, and stability for the detection of low levels of uric acid. The difference in detection values between the UAS and the commercial sensor is only ~4%. The primary feature of the saliva container is the processing of saliva by SF instead of CF. Samples from CF and SF showed no significant differences regarding uric acid levels, and both exhibited approximately 50% deviation from the untreated samples, while the difference in uric acid levels between the samples after SF and after applying both treatments was ~10%. Besides, insulation of the saliva container can partially eliminate sources of error induced by the environment during uric acid level testing. The PSSS provides a novel strategy for the immediate detection of specific markers in saliva. We believe that the PSSS has promising potential for future application in the rapid saliva testing.

In this work, the communication of a channel in the human body has a characteristic (time-domain) which can be measured at various distances in transmission and various frequencies of a signal by the printed circuit board-an analog frontend board (PCB-AFE) support. Besides, for the wideband signal of Body Channel Communication (BCC), a human body skin acts within a range of 1 Mb/s to 40 Mb/s as the transmission medium. This communication is more stable and attenuating low power while comparing with all another transmission medium in wireless. Moreover, due to the motion of a human body, this communication doesn't get affected. Though, the body antenna gives effects in the communication of a channel of the human body by occurs some interference. The Manchester data acts as encoder and decoder in transmitter and receiver parts respectively, in an AFE-PCB the Manchester encoder data is amplified after receiving the data from end to end channel of a human body. The data quality is improved by 7X sampler in clock data recovery (CDR) circuit. Therefore, the proposed design of reliable BCC Transceiver with SSCG and PNR Generator is processed in XilinxISE14.5, ModelSim Simulator 6.5a (Quartus II 8.1), and Micro wind software tools. It is also implemented in a XilinxXC9572XL kit. The power consumption and delay is reduced up to 90%, speed is increased up to 50% and leakage current is reduced up to 80% in the transmitter part.

Abstract Press-fit technology has been expected as a mounting technique instead of soldering in power electronics. To apply press-fit technology to power modules, the basic behavior of the contact resistance and an interface reaction of the press-fit contact are studied. Further, maintaining a stable contact force is important to maintain a low contact resistance. Factors that reduce the contact force include the displacement by the geometric tolerance of the pin and through-hole of the printed circuit board, and the thermal cycle load. We solved the problem by designing a new press-fit pin structure that provides the constricted portion for the body part of the press-fit pin, and clarified by thermal cycle test on power modules.

Recent advances in medical robotics have initiated a transition from rigid serial manipulators to flexible or continuum robots capable of navigating to confined anatomy within the body. A desire for further procedure minimization is a key accelerator for the development of these flexible systems where the end goal is to provide access to the previously inaccessible anatomical workspaces and enable new minimally invasive surgical (MIS) procedures. While sophisticated navigation and control capabilities have been demonstrated for such systems, existing manufacturing approaches have limited the capabilities of millimeter-scale end-effectors for these flexible systems to date and, to achieve next generation highly functional end-effectors for surgical robots, advanced manufacturing approaches are required. We address this challenge by utilizing a disruptive 2D layer-by-layer precision fabrication process (inspired by printed circuit board manufacturing) that can create functional 3D mechanisms by folding 2D layers of materials which may be structural, flexible, adhesive, or conductive. Such an approach enables actuation, sensing, and circuitry to be directly integrated with the articulating features by selecting the appropriate materials during the layer-by-layer manufacturing process. To demonstrate the efficacy of this technology, we use it to fabricate three modular robotic components at the millimeter-scale: (1) sensors, (2) mechanisms, and (3) actuators. These modules could potentially be implemented into transendoscopic systems, enabling bilateral grasping, retraction and cutting, and could potentially mitigate challenging MIS interventions performed via endoscopy or flexible means. This research lays the ground work for new mechanism, sensor and actuation technologies that can be readily integrated via new millimeter-scale layer-by-layer manufacturing approaches.
