Latest Patents

One of his latest patents is an imaging device with a pre-charged signal line. This invention aims to reduce banding in images caused by parasitic capacitance. The imaging device consists of an array of pixels arranged in rows and columns, with column signal lines that can be selectively coupled to the rows of pixels at predetermined times. Each pixel element features a photodetector connected to a reset switch, allowing it to receive a reset signal. The device includes a precharge circuit that places a voltage on the column signal lines. The method of operating this imaging device involves applying a precharge voltage, resetting the photodetectors, integrating the photodetector voltage, and sampling the integrated voltage on the signal lines. Additionally, when using a double sampling technique, the steps include resetting the photodetectors and sampling the reset voltages.

Another significant patent is for an electrical sensing apparatus and method utilizing an array of transducer elements.
