Latest Patents

Sakane’s patent titled “Apparatus and Method for a Communication Device” concerns a communication device, its installation, manufacturing, and use. The invention is designed to reduce the attenuation of magnetic flux when the device is attached closely to a conductive member, such as metal, and thereby help extend its communication distance. It uses sheet-like amorphous magnetic material extending from the magnetic-flux-generating portion of an RFID tag’s concentric disk-shaped antenna coil to an area outside the coil.

His other listed patent concerns a keyhole insertion for manholes, a manhole-cover locking apparatus and system, an unlocking method, and a control system for opening and closing manhole covers. The design aims to prevent unauthorized external access to a cover’s keyhole while enabling electrical locking components to be added to conventional covers. A control chip receives an unlock signal from an external reader/writer terminal and sends a signal that retracts pins from engaging openings, allowing access to the keyhole.
