Latest Patents

One of his latest patents is the High Speed Shift Register Circuit. This innovative circuit is designed for converting a form of a datum with N bits and comprises a shift register with a bit capacity of at least N+1 bits. Each bit of the shift register is set to achieve a predetermined logic condition by a setting means. The supply of shift pulses to the shift register is initiated, allowing the data to be shifted and predetermined data to be input in sequence. A detecting means monitors whether the shift register has completed the shift operations a predetermined number of times based on the logical condition of specific bits. Once the detecting means confirms the completion of the shift operations, the supply of shift pulses is halted. This shift register circuit can be utilized for both parallel to serial and serial to parallel conversions.
