Yoshihiro Shimizu is a notable inventor based in Itami, Japan. He holds 2 patents that showcase his contributions to the field of electronic engineering. His work primarily focuses on advancements in flow measurement and wireless communication technologies.

Latest Patents

One of his latest patents is an electronic flow meter. This innovative device includes a magnetic sensor, phase-A and phase-B drivers, a phase-A comparator, a phase-B comparator, a two-phase encoder, and a rotational speed timer. The two-phase encoder determines the normal or reverse direction of the impeller's rotation based on event signals sampled by the phase-A and phase-B comparators. This mechanism allows a counter to count up or down according to the determined direction, ultimately outputting an event count signal. The rotational speed timer calculates the impeller's rotational frequency from this event count signal and adjusts the sampling signals of the comparators accordingly.

Another significant patent involves a system debugging method and equipment. This invention utilizes a pulse transmission technique for wireless communication between a microcomputer and a debugger. The technique is based on magnetic field coupling between coils associated with both devices. During initialization, the microcomputer configures the communication conditions for wireless interaction. This innovation enables a contactless interface for system debugging without the need for large antennas or complex circuits.
