Latest Patents

Matsushima's latest patents include a proximity detection device and a proximity detection method. The proximity detection device features transmitting and receiving electrodes along with a multiline driving unit that applies periodic alternating voltages to multiple transmitting electrodes simultaneously. A measurement unit is responsible for measuring currents or accumulated charge from the receiving electrodes in sync with the voltage application. The linear computing unit processes these measurements based on the electrostatic capacitances at the intersections of the electrodes. Additionally, a proximity computing unit determines the approach and position of an object relative to a detection area using the computed data stored in memory.

Another notable patent is the proximity detector and proximity detecting method, which detects the approach of an object based on stray capacitance. This device includes a differential electrode with an apparent stray capacitance that changes in response to an approaching object. An individual capacitance detector measures the stray capacitance of the differential electrode by charging and discharging it in both opposite and same phases. The proximity calculator then uses this data to detect the object's approach.
