As field programmable gate array (FPGA) technology has steadily improved, FPGAs have become viable alternatives to other technology implementations for high-speed classes of digital signal processing (DSP) applications. In particular, radar front-end signal processing, an application formerly dominated by custom very large scale integration (VLSI) chips, may now be a prime candidate for migrati...

There is great demand today for real-time computer vision systems, with applications including image enhancement, target detection and surveillance, autonomous navigation, and scene reconstruction. These operations generally require extensive computing power; when multiple conventional processors and custom gate arrays are inappropriate, due to either excessive cost or risk, a class of devices ...

In this paper, an electromagnetic transient model of Fixed Capacitor/ Thyristor Controlled Reactor (FC-TCR) is developed and applied to the study of transients due to load variations. The work is then extended to custom power equipment, namely Distribution Static Compensator (DSTATCOM) and Dynamic Voltage Restorer (DVR) aimed at enhancing the reliability and quality of power flows in low voltag...

OVERVIEW Mirrorcle Technologies Gimbal-less Two-Axis Scanning MEMS Mirror Devices are based on proprietary ARI-MEMS fabrication technology initially developed through research projects at the Adriatic Research Institute (“ARI”) in Berkeley, CA. They provide very fast optical beam steering across two axes, while requiring ultra-low power. The mirrors deflect laser beams or images to optical scan...

The paper presents project of reprogrammable chip – FPGA, designed with current-mode gates novel digital gates operating with constant, continuous power supply current. Such continuous supply is a perfect one for analog-digital circuits, which are located on the same single die. Switching of digital part of the chip don’t disturb analog part. Based on the proposed approaches to minimizing logic...

The paper deals with the problem of designing mixed programmable analogue-digital circuits on a single die, and in particularly, with the problem of designing FPGA cells with current-mode gates novel digital gates operating with constant, continuous power supply current. Based on the proposed approaches to minimizing logic functions and designing digital current – mode circuits, the current-mod...

In the past few years, there have been huge research efforts into ubiquitous and context aware platforms that offer a user a custom level of service based on some known local parameters. The utility of such systems is greatly enhanced if a physical locational area can be determined. Recently, hybrid devices have been developed combining low power microcontrollers with short range FM radio trans...

In this thesis we investigate the feasibility of using information overheard by wireless devices to reduce their overall energy consumption for communications. Specifically we investigate the hypothesis “It is more efficient in terms of energy consumption to constrain the transmission power based upon a combination of received signal strength with a minimally extended MAC, than to utilise an un...
