Latest Patents

One of his latest inventions is a phase-comparison bit synchronizing circuit. This circuit is designed to establish bit phase synchronization of signals transmitted via Time Division Multiple Access (TDMA). It can reproduce data accurately even in the presence of disturbances. The circuit employs multiple phase-shifting units to adjust the phase of a given burst signal within a received frame. A bit phase synchronizing unit then synchronizes the bit phases of the output signals from these phase-shifting units. Additionally, a determining unit identifies the optimal phase-shifting unit, while a selecting/outputting unit outputs the signal produced by this unit. A memory unit stores the identification code of the determined phase-shifting unit, allowing for effective synchronization in subsequent frames.

Another significant patent is a power supplying system for terminal equipment. This system is tailored for subscriber terminal equipment and is designed to supply power based on an external power supply. It includes an excess current limiting circuit that halts power supply when excess current is detected, ensuring the safety and reliability of the system.
