Title: Kevin Hadfield: Innovator in Photoelectric Sensor Technology
Introduction
Kevin Hadfield is a notable inventor based in Chelmsford, GB. He has made significant contributions to the field of photoelectric sensor technology, holding a total of 2 patents. His work focuses on innovative methods for identifying and analyzing sensor arrays, which have applications in various technological domains.
Latest Patents
One of Kevin Hadfield's latest patents is the "Identification of a photoelectric sensor array." This invention involves a photoelectric sensor array that is labeled by accumulating charge, preferably from a dark current, in at least a portion of the sensor array. The accumulated charge is read out to form an image that determines the locations of atypical pixels within the sensor array. A signature of the sensor array is generated from these locations and stored for future identification. The array can be identified by re-accumulating charge to form a signature based on atypical pixels for comparison with the stored signature.
Another significant patent is the "System for identifying a photoelectric sensor array size having a detector for determining discontinuity in the readout charge from a readout register." In this system, the number of pixels in a dimension of a sensor array of photoelectric devices is determined. A readout register receives charge accumulated in the dimension of the sensor array. A clock applies clock cycle pulses to read out the charge for a predetermined number of clock cycles, which exceeds the supposed maximum number of pixels. A discontinuity detector identifies the last active pixel, while a counter counts clock cycles to determine the number of active pixels in the dimension of the sensor array.
