  • Publication number: 20230216542
    Abstract: A polling processing unit executes a polling process for detecting a device that performs NFC communication. An NFC communication processing unit executes a communication process of performing NFC communication with a mobile device detected by the polling process. Power consumption associated with execution of the communication process is larger than power consumption associated with execution of the polling process. When authentication of the mobile device by an authentication processing unit is completed, or when the execution of the communication process continues for a prescribed time period, the NFC communication processing unit executes a stop process of stopping the communication process until the execution of the communication process is permitted.

  • Publication number: 20230054306
    Abstract: A communication system includes a mobile device and an apparatus. The apparatus obtains unique data from the mobile device by using a common key while the common key is stored in the mobile device, generates a unique key by using the obtained unique data, stores the generated unique key as a service key in the apparatus, and transmits the generated unique key to the mobile device. When the mobile device receives the unique key from the apparatus while the common key is stored in the mobile device, the mobile device rewrites a service key stored in the mobile device from the common key to the unique key.

  • Patent number: 6917169
    Abstract: A field effect transistor is provided between the ground and an H bridge circuit for rotating a motor in forward and reverse directions in a manner that the drain of the transistor is grounded and the gate thereof is coupled to a DC power source such as a battery serving as a bias source which supplies electric power to the H bridge circuit. Thus, when the DC power source such as a battery is reversely connected, the field effect transistor normally in an on state is turned off. A controller monitors the source voltage of the field effect transistor, and when the controller detects an excess current, the controller outputs a control signal to the high-side driver to prevent the supply of electric power to the motor.
