Latest Patents
Walden's most recent patents exemplify his innovative approach to charge transfer technology. The first patent, titled "Two-dimensional transfer in charge transfer device," outlines a device that allows movement of charge carriers in two noncollinear directions across its surface. This design utilizes a network of electrodes with dual levels of metallization, combined with specific doping of the storage medium, to define charge transfer paths. The direction of movement is controlled through various pulsing sequences, allowing for versatile applications in both charge coupled devices (CCDs) and bucket brigade devices.
His second patent, "Charge transfer binary counter," introduces a two-phase binary counter capable of measuring signal pulse counts within a defined time interval. The invention features a charge storage medium with Q-cells designed to convert each signal pulse into a charge packet. Accompanying one-bit shift registers enhance the counter's ability to accurately quantify signal inputs, utilizing controlled potential barriers to facilitate charge transfers. This innovative structure ensures that at the end of a time interval, the stored charge packets accurately represent the binary equivalent of the incoming signal pulses.
