  • Publication number: 20130235505
    Abstract: A solenoid control device executes feedback control such that a drive current for a solenoid follows a target current, by driving, through PWM, a MOSFET provided on a power supply line to the solenoid. An overcurrent detection circuit that outputs an overcurrent detection signal when the drive current for the solenoid reaches an overcurrent determination current value is provided, and it is determined whether an overcurrent is generated. Whether a short-circuit occurs between both terminals of the solenoid is determined by monitoring whether the overcurrent detection circuit is repeating an output of the overcurrent detection signal and a stop of the output of the overcurrent detection signal.

  • Patent number: 7894808
    Abstract: A secret information storing unit stores a common key which is authenticated between the data storing apparatus and a telecommunications apparatus. A data communication unit receives data from the telecommunications apparatus. The data includes an update of a first data item which is downloaded by the telecommunications apparatus from an information provider via a wireless network and encrypted using the common key. A data storage stores the encrypted update of the first data item received at the data communication unit, and further detaches from the data storing apparatus and independently connects directly to the telecommunications apparatus. The data communication unit sends the encrypted update of the first data item stored in the data storage to the telecommunications apparatus in response to a request from the telecommunications apparatus.
