Denso Assigned Patent

Denso Corporation, Kariya, Aichi-pref., Japan, has been assigned a patent (9,633,699) developed by Hasegawa, Takaomi, Watanabe, Satoshi, Hayashi, Hiroki, and Nawa, Hiroki, Kariya, Japan, for a “data storage control device.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A data storage control device controls a memory card which, including a non-volatile rewritable memory, operates using an external power supply. A DC/DC converter generates, by having a power supply of a +B voltage, a card operating voltage for operating the memory card. When delayed ACC is completed after an accessory power supply of a vehicle is turned off, a main microcomputer, a shutdown signal control unit, and a transistor set a shutdown terminal of the DC/DC converter to a low level by setting a main control signal input terminal to a high level and, thereby, stops operation of the DC/DC converter. This inhibits the occurrence of a case in which, after the accessory power supply of the vehicle is turned off, the circuit supplying power to the memory card affects other devices mounted in the vehicle.”
