Latest Patents

Fujii's latest patents showcase his innovative approaches in these technologies. One of his recent inventions is a battery pack design, where the first cell string in a battery module has a larger allowable current value than the multiple cell strings in second and third battery modules. This design incorporates a current-limiting circuit that restricts the charge and discharge currents of the second cell string. Notably, when the current sensor detects a zero value, the switch is turned off. If there's a discrepancy in terminal voltage between the second and third cell strings, a switch is activated to adjust the connections, ensuring optimal performance.

Another significant patent is a method for correcting high-frequency characteristic errors in electronic components. This innovative method allows calibration work on two-terminal impedance components to be done using the same measuring system employed during actual measurements. Fujii's process involves measuring multiple correction data samples with differing high-frequency characteristics, determining an equation that relates the values measured across systems, and calculating an estimated high-frequency characteristic value for the electronic component in question.
