Direct interfacing with brain tissues for neuroscience, neural prosthetics, and local treatment of brain diseases necessitates the implantation of arrays of electrodes to stimulate, record electrical activity, and deliver drugs to specific locations in the brain. Here, we present novel elongated multi-modal neural microprobe capable of simultaneously recording the electrical activity of the brain and delivering drugs to the diagnosed location through polymeric microchannel embedded on top of the electrode. The functionality of the electrical part of the microprobe was tested in rats and high frequency spikes were recorded.

Li-ion rechargeable batteries present an useful energy, low battery effect, and slow Self-discharge loss of charge when not in use. In this paper, we describe a VHDL-AMS model describing coupled electrical and thermal behaviors of a Li-Ion cell. This model relies on the experimental extraction of real characteristic parameters by using an efficient and low-cost test bench. Therefore, it allows to predict the realistic voltage variations by taking into account the state of charge and heating of the Li-ion cell, in order to design a battery system according the required capacity and electric power for the current electrical applications.

Compressed sensing (CS) is applied in wireless body sensor network (WBSN) to reduce the data rate and minimize the power consumption of the sensor nodes. However, as the CS encoder and decoder are tightly coupled, a model of the overall acquisition chain is required in the first stages of development and validation. To overcome this issue, we propose a virtual prototyping of WBSN based on CS with SystemC-AMS 1.0. The proposed model consists of three sensor nodes which capture electrocardiogram (ECG), electromyogram (EMG) and respiration (RESP) signals. The proposed virtual prototype had allowed a functional verification of WBSN at system level and a rapid exploration of the impact of compression ratio on the quality of reconstruction. Results show how to tailor the measurement matrix for a best tradeoff between the compression ratio, the quality of reconstruction, and the energy consumption.

Rare events can potentially occur in many applications, particularly in hyper spectral image analysis. When manifested as opportunities to be exploited, such events become of paramount significance. Due to their sporadic nature, the information-bearing spectral vectors associated with rare events often lie in a large set of irrelevant signals and are not easily accessible This paper provides a statistical frame of a local criterion to measure the rate of the conservation of these rare events during of the dimension reduction. The core component of this framework is a sampling procedure that adaptively and quickly focusses the information-gathering resources on the segments of the data set that bear the information pertinent to the rare events. A particular accent is put on the local vectors in every spectral band with the aim of measuring the rate of the conservation of the rare vectors.

Using measure/stress/measure (MSM) protocol, Negative bias temperature instability (NBTI) has been investigated on P-and N-substrate MOS capacitors through flat band shift evolution. The same protocol on p-MOSFET's transistors, with different channel lengths, has been also examined through threshold voltage shift evolution. The results have shown that P-substrate MOS capacitors are more affected than N-substrate MOS capacitors. We have suggested that the amphoteric nature of interface traps and the positive nature of the oxide traps could explain this result. In addition, the exponent n is higher in N-substrate than in P-substrate capacitors. Higher the degradation is, lower n is. On the other hand, we have shown that P-doped lightly doped drain (LDD) and source/drain regions of p-MOSFET transistors are more affected than the middle of the channel under NBTI stress conditions. These results point out the influence of the Boron doping on the NBTI degradation. Also, this behavior suggests that the generation mechanism in the edge region is different from that in the channel region.

This paper describes the development of an embedded system that automatically classifies microcalcifications detected on digital mammograms into one of the five types proposed by Mich`ele Le Gal, a classification scheme that allows radiologists to decide whether a breast cancer is malignant or not without the need for surgeries. The hardware part of the developed system is based on an Altera Nios II software processor and the embedded software is based on wavelets and artificial neural networks. We have used an Altera DE2-115 development kit in order to create a custom System-on-Chip (SoC) that has many advantages over common desktop computers. In our tests the system correctly classified 94.90% of test images, proving it can be used as a second opinion by radiologists in breast cancer early diagnosis.

In this paper, we present implementation of object tracking system targeting video sequence based on Particle Swarm Optimization (PSO) using Structural SIMilarity index (SSIM) as PSO's fitness function on field programmable gate array (FPGA). The proposed algorithm's performance has been tested and evaluated over different video sequences, showing its adaption for tracking in real-time. After presenting PSO algorithm and SSIM index, we show how the system's architecture has been simplified for FPGA implementation and achieved better results than its software implementation counterpart.

This paper proposes a new reliable router allowing accurate online error detections in dynamic Network on Chip (NoC). The proposed router has the capability to detect and localize accurately inner or outer data packet errors of the router while distinguish between temporary and permanently errors. The error detection mechanisms of the proposed switches and advantages with regards to the other main already proposed router approaches are detailed while proving the feasibility and efficiency through several simulations online detection cases. Performance evaluation and FPGA implementation results are also given.

This paper presents a compact and power efficient ultra-violet (UV) dosimeter design. The compact design is achieved by incorporating the principal dosimeter functions onto a CMOS integrated chip. Besides, the external components are arranged in order to minimize the global board BoM (Bill of Materials). On the power consumption side, the CMOS integration aims to reduce the maximum power consumption levels. In addition, a regular sleep/wake-up technique is employed to further decrease the global average power consumption. The high-power blocks are driven by a variable duty-cycle integrated oscillator and turned ON only during short time slots. The device is powered by a primary solar rechargeable battery and a secondary standard emergency battery. The emergency battery is only used when the rechargeable battery gets unable to supply the circuit. The proposed solution aims to prevent any battery replacement during the life-time of the product. An external tri-color LED indicates the skin exposure risk level to UV rays.

Ultra-wideband (UWB) technology for the localization of wireless sensor networks has received considerable attention last few years. This technology is dedicated for indoor localization using a fine delay of resolution and obstacle-penetration capabilities. A lot of challenges remain before implementation of UWB can be deployed on a large scale like non-line-of-sight (NLOS which is especially critical for most location-based applications because the NLOS propagation introduces positive bias in the estimation of distance, which can seriously affect the performance of localization.In this paper, we present a technique for identifying between both line-of-sight(LOS) and non-line-of-sight (NLOS) contexts based on stable distribution parameters using SVM (Support Vector Machine) methods for classification. This characterization was applied to UWB measurements collected from whyless.com project by the IMST group, over bandwidth of 10 GHz.
