Abstract: An analog-to-digital converter (ADC) sampling system and method for imaging and non-imaging systems to conserve power consumption is provided. The ADC sampling system performs only two comparisons for each pixel based on a background value and a threshold value to determine whether the light detected by the pixel is different from a background image.

Abstract: An imaging system for low-power and low data-rate applications is provided. The imaging system comprises a pixel array having a plurality of photosensitive elements (pixels) divided into a plurality of groups of photosensitive elements (super pixels). An image processor is operably connected to the pixel array and configured to selectively operate each group of photosensitive elements in either (i) a high resolution mode in which the pixel array outputs readout voltages corresponding to all of the photosensitive elements in the respective group of photosensitive elements or (ii) a low resolution mode in which the pixel array outputs readout voltages corresponding to only a subset of the photosensitive elements in the respective group of photosensitive elements. Groups of photosensitive elements corresponding to detected motion in each image frame are operated in the high resolution mode, while the remaining groups of photosensitive elements are operated in the low resolution mode.

Abstract: A vision traffic marker network system comprises a plurality of vision traffic markers or traffic nodes configured to capture information such as an event, an environment, a profile, or a condition of an object such as vehicle, human, combination thereof, or the like, for example. The environment information may be time of day, day of week, weather, traffic condition, and the like. The nodes may be one of a traffic node, an ambient node, a repeater, a gateway, or a combination thereof. These nodes are arranged in network neighborhoods and configured to communicate with at least one of the communication networks with at least one of the vision traffic markers or nodes, a control system, the automotive, a server, a global navigation system, other non-vision devices, traffic lights, street lights, electronic devices, or combination thereof, via one more links, either wirelessly or wired communication.

Abstract: A transmitter for an optical device includes semi-conductor waveguides, each incorporating an electro-optic phase-shifter in the semi-conductor waveguide that is operable to change the refractive index of the waveguide to thereby introduce a phase shift in the light propagated through the waveguide. The electro-optic is connected to a phase shift controller and to a temperature measurement component, such as a PTAT circuit, that is integrated into the electronic or photonic chip carrying the waveguide. Temperature measurement by the measurement component can be multiplexed with the normal operation of the phase-shifter so that the temperature measurement function does not interfere with the phase shifting function.

Abstract: A sensor circuit enables detection of DC offset in a sensor output signal. The sensor circuit includes a sensor that generates a sensor output signal corresponding to a physical signal coupled to an input of the sensor, and a modulator that generates a modulation signal, the modulator being coupled to the sensor to modulate a physical parameter of the sensor and to enable a DC offset to be separated from the sensor output signal. To enable the circuit to measure the DC offset even though the sensor output signal is inversely proportional to the output signal, the circuit includes a feedback circuit configured to generate a feedback signal. The feedback signal is coupled to the input of the sensor to enable the physical parameter of the sensor to be modulated without modulating a portion of the sensor output signal attributable to the physical signal being converted to an electrical signal by the sensor.
