20100220857 | SYSTEM AND METHOD FOR REGISTERING SECRET KEY - A secret key registration system which registers a secret key in a portable key device and vehicle. A first transformation equation is stored in a writer and the vehicle. A second transformation equation is stored in the portable key device and the vehicle. The writer transmits a registration code to the portable key device and generates intermediate data with the first transformation equation of the writer. The intermediate data is transmitted to the portable key device, which generates the secret key from the intermediate data with the second transformation equation. The portable key device transmits the registration code to the vehicle. The vehicle generates intermediate data from the registration code with the first transformation equation of the vehicle, and then generates the secret key from the intermediate data with the second transformation equation. | 09-02-2010 |
20120111709 | Switch Device - A switch device includes a lid arranged between a tactile switch, which is arranged on a substrate, and an operation button, which is coupled to a retainer so that the operation button can be pushed. The lid includes an opening at a location corresponding to the tactile switch. A lower surface of the elastic member is coupled to a surface of the lid. The operation button, when pushed, activates the tactile switch with an elastic member. The operation body, when released from the pushed state, deactivates the tactile switch as a reaction force of the elastic member returns the operation button to an initial position. The switch device includes a projection that supports the operation button. The projection is formed on an upper surface of the elastic member at a location corresponding to the surface of the lid. | 05-10-2012 |
20130009763 | CONTROLLER FOR TIRE PRESSURE MONITORING SYSTEM - A controller for a tire pressure monitoring system includes a control unit that receives information signal related to tire air pressure and tire temperature from a sensor unit arranged in each tire. The control unit notifies a user when determining from the information signal received subsequent to pressure adjustment of the corresponding tire that the tire air pressure of the corresponding tire would be excluded from a recommended pressure range as the present tire temperature changes to a monitoring subject temperature. | 01-10-2013 |
20140145833 | REGISTRATION DEVICE - A registration device includes a processor that writes an ID code to an invalid ID code storage region in accordance with management data, updates the management data after the ID code is safely written, and validates the invalid ID code storage region storing the ID code. After the ID code is written, when an ID code is stored in every one of the ID code storage regions, the processor updates the management data to invalidate the ID code storage region excluding the invalid ID code storage region storing the ID code. | 05-29-2014 |
20140363716 | BATTERY HOLDER - A battery holder includes a terminal component electrically connected to one electrode of a battery and a battery restraining part that is separate from the terminal component. The terminal component includes: a fixed portion fixed to a mounting surface; an arm portion extending from the fixed portion to come into contact with said electrode; and a cutout portion opened toward the battery in said arm portion. The battery restraining part is located between the terminal component and the battery while being received by the cutout portion, in order to accept an impact load from the battery. | 12-11-2014 |
