Title: The Innovative Contributions of Eiichi Ishii
Introduction
Eiichi Ishii is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of technology, particularly in tire condition detection systems and non-contact data transmission methods. With a total of 15 patents to his name, Ishii continues to push the boundaries of innovation.
Latest Patents
One of his latest patents is a tire condition detection system that utilizes an external solenoid positioned outside a tire and an internal solenoid located within a valve of the tire. This innovative design transmits and receives power through an alternating magnetic field in a predetermined high frequency band. This method generates an induced alternating current in the internal solenoid, serving as a new power source for tire pressure and temperature detection devices, eliminating the need for batteries. When the alternating magnetic field is well matched to the tire's physical and electrical structure, it creates a stable power reception as the tire rotates.
Another notable patent is the loop antenna device, which consists of multiple small loop antenna cells magnetically coupled to a non-contact type data carrier antenna coil. The design ensures that the directions of the magnetic moments of the signals transmitted are opposite to each other, resulting in a net magnetic moment of zero. This innovative approach allows for compensation of imbalances between the small loop antenna cells, enhancing the efficiency of data transmission.
