Latest Patents

One of his latest patents is for a matrix-array detector with controlled-impedance row conductors. This innovative detector features an array of pixels sensitive to physical effects, arranged in a matrix format. Each pixel generates a signal based on the physical effect, and the design includes row conductors that allow for the driving of pixels in a specific row. The driver modules deliver selection signals to these row conductors, enabling the selection of rows based on high and low signal levels. Additionally, impedance modules are integrated to maintain low impedance during the reading phase of the pixel array.

Another significant patent involves a method for controlling a photodetector by automatically detecting incident radiation. This method is applicable to digital X-ray detectors that consist of an array of light-sensitive points. Each point is connected to a column conductor and line conductors, with a light-sensitive element that converts photon flux into electrical charges. The method utilizes a capacitor for cross-coupling between the transistor's drain and source, allowing for potential variations upon photon reception. The process includes comparing these variations with a threshold to read the light-sensitive points
