Patent number: 10418802Abstract: A calibration circuit according to various aspects of the present invention comprises a battery pack, a protection IC, and a power source. The power source may have a predetermined voltage and may be selectively coupled to the protection IC. The power source may be capable of providing a current to the protection IC through one of a first current loop and a second current loop, wherein the current through the first current loop generates a first voltage across a first and second terminal of the protection IC, and the current through the second current loop generates a second voltage across the first and second terminals that is substantially equal to the voltage of the power source.Type: GrantFiled: April 4, 2017Date of Patent: September 17, 2019Assignee: SEMICONDUCTOR COMPONENTS INDUSTRIES, LLCInventors: Atsushi Kamei, Yasuaki Hayashi, Katsumi Yamamoto

Patent number: 4926332Abstract: A locking device for vehicles includes a card including a microprocessor and a transmitter for generating and transmitting commands for locking and unlocking the doors of a motor vehicle. A lock control device includes a microprocessor and a receiver for receiving the commands transmitted by the lock command device. The lock control device will only carry out a receive command if the command is applied to a specific motor vehicle and the motor vehicle is in the proper state to implement the command. Change data is generated by the lock control device and transmitted to the lock command device to change the value of the next subsequent lock command so that the lock command can be uniquely identified with the motor vehicle.Type: GrantFiled: November 15, 1988Date of Patent: May 15, 1990Assignee: Aisin Seiki Kabushiki KaishaInventors: Kenichi Komuro, Taneichi Kawai, Atsushi Kamei, Toru Asada, Nozomu Torii, Ryoichi Fukumoto

Patent number: 4723265Abstract: A microprocessor-based telephone set includes a telephone number memory, a number indicator, an abbreviated number selecting switch, an abbreviated number controller, and a selecting signal controller. The call is made when a selecting signal is sent to a base station. The selecting signal is issued when selecting signal controller retrieves a certain telephone number of a called party according to a displayed abbreviated number on the indicator on receiving a signal controlling the transmission start of the selecting signal. The signal which controls the transmission start of the selecting signal can be generated by means of the same switch that hook-signals. The telephone equipment can be installed on a steering wheel of an automobile.Type: GrantFiled: September 27, 1985Date of Patent: February 2, 1988Assignees: Aisin Seiki Kabushiki Kaisha, Toyoda Gosei Co., Ltd.Inventors: Atsushi Kamei, Chikahisa Hayashi, Makoto Kanai
