Lab-on-CMOS chips (LOCMOS) are sophisticated miniaturized analysis tools based on integrated circuit (IC) microchips performing various laboratory functions. We have developed a low temperature co-fired ceramic (LTCC) package for a LOCMOS application regarding cytotoxicity assessment of nanomaterials. The LTCC packaged capacitance sensor chip is designed for long-term cell viability monitoring during nanoparticle exposure. The introduced LTCC package utilizes the flip chip bonding technique, and it is biocompatible as well as able to withstand the environmental conditions required to maintain mammalian cell culture directly on the surface of a complementary metal oxide semiconductor (CMOS) integrated circuit.

Finite state machine (FSM) takes an important part in digital logic system. FSMs partition is one of the effective methods in regards to low power technique. Most of time only one of sub-FSMs need to be clocked, consequently power is saved. In this paper, we propose a high performance algorithm based on state transitions probability and low complexity control logic to implement the partitioned FSMs. The cost from one sub-FSM to other sub-FSMs could be minimum, and the transitions probability in one sub-FSM should be maximum. Based on the low complexity of control logic, we further give an optimized hardware architecture for the partitioned FSM model. Our proposed scheme has been implemented by using tsmc 45 nm technology library. Experimental results show that an average power reduction of 59% has been obtained for a set of standard FSM benchmark circuits.

This paper describes the design and implementation of three-dimensional (3-D) Haar with transpose-based computation and distributed arithmetic (DA). As a results of the separately property of the multi-dimensional Haar wavelet transform (HWT), the proposed architecture has been implemented using a cascade of three N-point one-dimensional (1-D) Haar and two transpose memories for a 3-D volume of N × N × N, suitable for 3-D medical image compression. The 3-D HWT architecture were implemented on SubRIO-9632 board National Instrument. Experimental result and analysis of area, power consumption and maximum frequency are discussed in this paper.

Medical surgeries in the space environment, including long term space travel (e.g., to Mars) and permanent presence on other planetary bodies (e.g., Moon and Mars), are posing an inherent logistical, and in the absence of appropriately trained personnel (i.e., surgeons), even a potentially life-threatening challenge. As a potential mitigation the use of an existing surgical trainer tool that would allow crewmembers to acquire basic surgical skills is proposed, and to train space station personnel both in space and on the Moon and Mars to hone these skills long-term. Furthermore, this tool would potentially allow for tele-conducted surgeries, akin to the da Vinci Surgical System, controlled from Earth but executed onboard, e.g., the International Space Station. On Earth the surgical trainer can be used to train surgeons and flight surgeons. The efficiency of any surgical training system plays a significant role in its reduction of operative risks and stress associated with insufficient experience of the trainee. The primary goal of such systems is to raise the trainee to a higher level of proficiency without putting patients at risk in the operating room. The prototype for the computer Assisted Surgical Trainer (CAST) being developed at the University of Arizona realizes an optimal motion-planning algorithm. The underlying system consists of mechanical fixtures equipped with encoders and DC motors. This hardware provides a means to accurately track the tip movements of laparoscopic instruments used in minimally invasive surgery. Furthermore it provides haptic and visual feedback to trainees by using a PID controller and augmented reality visualization. Examples of surgical guidance and the improvement of surgeon performance over time using CAST are presented.

A balanced-to-single-ended (BTSE) power divider is proposed in this paper. Its input is a differential pair while both the outputs are single-ended ports. It can replace the cascade of a balun and a conventional power divider. The characteristics requirements of a two-way BTSE power divider with equal power division are first derived, and then a prototype is designed for 2.0 GHz. In order to construct the component compactly, a short-ended four-wire coupled line and T-shaped sections are utilized to realize a -90° transmission line and a phase inverter, respectively. The developed prototype occupies an area of 0.077 λg2, where λg is the guided wavelength of central frequency. It provides all the desired performances within the operating bandwidth of 25%, with low insertion loss and good balance also achieved. © 2014 IEEE.

When newborns present with jaundice, various clinical assessment need to be executed including evaluation of the history, physical examination, and assessment of severity of jaundice. This project concerns with the quantification of neonatal jaundice level using Simulink model-based design. It is important to address that the proposed method is non-invasive, hence suitable for infants. In this project, the concentration level of bilirubin in dermis layer of skin has been detected using skin optic theory with light emitting diode (LED) and photodiode as a detector. To evaluate the proposed system, a mock skin soaking is used to replace the real infant's skin. At the system level, Arduino Uno has been used as a hardware platform, whilst MATLAB and Simulink have been fully utilised to implement the system's architecture. An evaluation of the proposed systems reveals its capability to detect, process and display real-time results with three (3) levels of jaundice, including normal, mild and critical.

A compact ultra-wideband (UWB) bandpass filter with an inherent notched band and steep slopes has been presented and implemented with the low temperature cofired ceramic technology. The filter is realized by a stepped-impedance T-shaped resonator (SITR) coupled to a pair of quarter-wavelength input/output feed-lines. The proposed SITR can facilitate not only a notched band, but also sharp roll-off characteristics. Measured results agree well with the HFSS simulated results. The whole size of the UWB filter is only 6.0×6.0×1.92 mm 3 .

With increasing usage of mobile devices to watch mobile video, the battery consumption of mobile devices will be dominated by video delivery and playback. In this paper, we develop battery efficient video delivery techniques that vary video transmission rate dynamically depending on battery and buffer levels of the mobile device, the channel conditions experienced, and video quality requirements while maximizing battery life and ensuring user experience. The proposed dynamic video rate adaptation techniques enable the base station to adapt the Multi Input Multi Output (MIMO) transceiver configurations to reduce battery current required by MIMO components on the mobile device. The proposed techniques also make the base station stop video transmission opportunistically, thereby eliminating the battery load imposed by the mobile MIMO components. Experiments conducted under various network conditions for various video download profiles show that more than 50% improvement in battery lifetime is possible in comparison to conventional video download techniques not aware of battery.
