He has made significant contributions to the field of radio frequency identification technology, holding a total of four patents. His work focuses on enhancing the efficiency and effectiveness of item identification systems.
Latest Patents
One of Ishii's latest patents is a method and apparatus for identifying a set of multiple items on a conveyor system using multiread transponders. This innovative apparatus includes a conveyor designed to identify a plurality of items, each equipped with a radio frequency transponder. A three-dimensional (3D) radio frequency antenna is strategically positioned on one side of the conveyor. The conveyor features a movable part that transports the items into and out of the antenna, ensuring that the items are completely surrounded by the antenna during identification. The reader sends interrogation signals to the transponders via the antenna, effectively reading identification information from them. The 3D antenna is equipped with multiple coils arranged in a 3D configuration, creating a reading field that allows for the interrogation of all transponders within that field. Additionally, noise compensation coils are included at opposite ends of the reading field to minimize electromagnetic radiation and external noise interference. Another patent involves an air coil RF transponder, which consists of a rotatable carrier, such as a rigid reel, around which a coil is wound. This design ensures precise distances between windings, enhancing the performance of the transponder.
