An omnidirectional sensor array system, for example a panoptic camera, comprising a plurality of sensors arranged on a support of predetermined shape to acquire data, wherein said sensors are directional and wherein each sensor is attached to a processing node which comprises integrated electronics that carries out at least a portion of the signal processing algorithms locally in order to reduce the computational load of a central hardware unit.

Omnidirectional sensor array system

Disclosed are low power electronic devices configured to exploit the sub-threshold swing, unidirectional tunneling, and low-voltage operation of steep slope-tunnel tunnel field-effect transistors (TFET) to improve power-conversion efficiency and power-efficiency of electrical systems incorporating the TFET as an electrical component to perform energy harvesting, signal processing, and related operations. The devices include a HTFET-based rectifier having various topologies, a HTFET-based DC-DC charge pump converter, a HTFET-based amplifier having an amplifier circuit including a telescopic operational transconductance amplifier, and a HTFET-based SAR A/D converter having a HTFET-based transmission gate DFF. Any one of the devices may be used to generate a RF-powered system with improved power conversion efficiencies of power harvesters and power efficiencies of processing components within the system.

Low power nanoelectronics

A real-time stereo camera disparity estimation device comprises input means arranged to input measured data corresponding to rows of left and right images; a plurality of on-chip memories arranged to buffer the input measured data; a vertical rotator hardware module configured to align the rows of left and right images in a same column; a reconfigurable data allocation hardware module; a reconfigurable computation of metrics hardware module; and an adaptive disparity selection hardware module configured to select disparity values with the minimum matching costs.

Hardware-oriented dynamically adaptive disparity estimation algorithm and its real-time hardware

An event-driven tracking analog to digital converter (ADC) architecture is proposed. The proposed architecture has less sensitivity to amplifier and DAC non-linearity, reduces the swing and dynamic common-mode range requirement of the operational transconductance amplifier (OTA) and comparators, respectively.
