Smart pixel architectures offer important new opportunities for low cost, portable image processing systems. They provide greater I/O bandwidth and computing performance than systems based on CCD and microprocessors. However, finding a balance between performance, flexibility, efficiency, and cost depends on an evaluation of target applications. This paper describes several promising architectu...

A communication system between two autonomous micro air vehicles is proposed. Laser communication offers advantages in range, power, and bandwidth when line of sight is available. Beamsteering is accomplished using gyro-stabilized MEMS micromirrors. A custom CMOS smart-pixel imager implements a 1Mbps receiver, including analog front-end and variable-gain amplifier at each pixel. Algorithms are ...

We present a CMOS image sensor dedicated to lightning detection and imaging. The detector has been designed to evaluate the potentiality of an on-chip lightning detection solution based on a smart sensor. This evaluation is performed in the frame of the predevelopment phase of the lightning detector that will be implemented in the Meteosat Third Generation Imager satellite for the European Spac...

A low power smart vision system based on a large format (currently 1KxlK) active pixel sensor (APS) integrated with a programmable neural processor for fast vision applications is presented. The concept of building a low power smart vision system is demonstrated by a system design, which is composed with an APS sensor, a smart image window handler, and a neural processor. The paper also shows t...

Present Embedded industry is emphasising more on Smart devices and they have gained much importance in daily life. The devices includes communication, Bio-Medical, image processing, Power, etc. While using smart devices (iButton Technology) data acquisition and user authentication has to be done.Various security concepts are developed to suite these requirement. One such security measure is usi...

A smart-pixel array is a two-dimensional array of optoelectronic devices that combine optical inputs and outputs with electronic processing circuitry. A field-programmable smart-pixel array (FP-SPA) is a smart-pixel array capable of having its electronic functionality dynamically programmed in the field. Such devices could be used in a diverse range of applications, including optical switching,...

We consider a problem domain consisting of a quadratic grid of n “smart pixels” which observe a black-andwhite image. Each of these smart pixels can communicate with its direct neighbors and perform simple computations. Contiguous groups of black pixels form objects on the grid. We present a deterministic algorithm to compute the convex hulls of all objects on the pixel grid simultaneously in t...

SMART-X is a mission concept for a 2.3 m2 e ective area, 0.5 ′′ angular resolution X-ray telescope, with 5 ′ FOV, 1 ′′ pixel size microcalorimeter, 22 ′ FOV imager, and high-throughput gratings.
