Title: The Innovations of Susumu Sumida
Introduction
Susumu Sumida is a notable inventor based in Gyoda, Japan. He has made significant contributions to the field of logical waveform generation and data comparison devices. With a total of 2 patents, his work has had a considerable impact on technology.
Latest Patents
One of his latest patents is the "Logical Waveform Generator." This invention involves a data dividing circuit that sequentially divides input logical data into n data trains, each with an n time slot length. A clock signal, which can be arbitrarily timed, is divided into n clock signals that are displaced one time slot apart in phase. These divided clock signals are controlled by the corresponding data trains and are time multiplexed to produce output data that is synchronized with the input logical data.
Another significant patent is the "High-Speed Data Logical Comparison Device." In this invention, reference logical data is spatially divided by a data dividing circuit for each time slot. The divided data is then converted into a continuous effective period. Comparators are used to compare the divided and converted reference data with input logical data to determine if they coincide. A clock signal for timing the comparison is also divided into n clock signals, which are used to extract outputs from the comparison circuit.
