Abstract: In a light sensor test unit, a test circuit is built in a display panel and connected to an output node of a light sensor which senses an intensity of an external light. When external light having a predetermined intensity is provided to the light sensor, the test circuit outputs a driving signal in response to a sensing signal output from the output node. A test pixel part includes pixels selected from a plurality of pixels arranged in the display panel and receives the driving signal from the test circuit to display a gray-scale corresponding to the driving signal. A brightness measurer measures a brightness corresponding to the gray-scale displayed in the test pixel part to compare the measured brightness with a predetermined brightness, thereby testing whether the light sensor built in the display panel is normally operated.

Abstract: Systems and methods for reducing erroneous weighing of items such as by detecting items extending beyond a periphery of a weigh platter whereby in one configuration, the system employs a light guide for routing a light beam to a detector operative to detect interruption of the beam due to an item encroaching upon or overhanging an edge of the platter. In another configuration, the scale includes a perimeter gap between the platter outer edge and scanner housing frame or checkout counter, a light beam directed angularly upward through the gap is partially obstructed by the frame and platter whereby light exits the gap forming a light plane, wherein an object placed on the platter extending across the gap intersects the light plane thus scattering light rays, some of which are sensed by a detector. Various indicators for alerting the operator of off-scale detection are also described.

Abstract: An image forming apparatus includes a sensor having a light emitting section for irradiating a detection area and a light receiving section for outputting a light sensitive signal indicative of the amount of the light received from the detection area. A sensor adjustment section adjusts the sensitivity of the sensor by varying the set value of an adjustable characteristic value associated with the sensitivity, based on explorative measurement of the adjustable characteristic value corresponding to a predetermined reference level of the light sensitive signal. If an estimation section estimates that the amount of a leakage current generated on the light receiving section is larger than a reference amount, a mitigation section mitigates the influence of the leakage current on the explorative measurement, by at least one of adjustment of the light receiving section for reduction of the leakage current and modification of the predetermined reference level.

Abstract: An apparatus using reconfigurable integrated sensor elements with an efficient energy harvesting capability is described. Each sensor element has sensing and energy harvesting mode. In the sensing mode, the sensor element measures an environmental characteristic by generating electrical charge and outputs a time-encoded signal indicative of the measurement. In the energy harvesting mode, the sensor element itself is used to harvest energy from ambient energy source and makes it available to other sensor elements or circuit components. The sensing element is switched from the sensing mode to the energy harvesting mode when the electrical charge reaches a predetermined threshold. An image sensor device using asynchronous readout for harvesting energy from incident light while generating images is also described.
