  • Publication number: 20130162421
    Abstract: An information communication system has a vehicle portable device that conducts wireless communication with a vehicle, and a mobile terminal that includes a display part and conducts near-field wireless communication with the vehicle portable device. The vehicle portable device includes a vehicle information acquisition part that acquires vehicle information on the vehicle, wherein the vehicle information is transmitted from the vehicle by wireless communication, and a transmission controller that controls the transmission of the vehicle information to the mobile terminal by near-field wireless communication. The mobile terminal includes an execution controller that acquires the vehicle information transmitted from the vehicle portable device and controls execution of a predetermined program for displaying the vehicle information on the display part.

  • Patent number: 4998177
    Abstract: An electromagnetic solenoid drive apparatus for use in a vehicle for turning on an electromagnetic solenoid from a battery every time when a command switch is turned on comprises first and second resistors connected in series to each other on an electric line for flowing an electric current through the electromagnetic solenoid; a first switching element turned on in a state in which an output voltage of the battery is lower than a predetermined threshold voltage and short-circuiting both ends of the first resistor; a timer circuit operated for only a constant time in association with the turning-on operation of the command switch; and a second switching element turned on during only the operating period of the timer circuit and short-circuiting both ends of the second resistor.

  • Patent number: 4788474
    Abstract: An improved dimmer apparatus which can protect an output power transistor for a lamp of a load when the lamp is short-circuited and which can eliminate manual operation for restarting the apparatus after recovery of the short-circuiting of the lamp. The apparatus comprises a detecting circuit which detects short-circuiting of the lamp to turn the transistor off. After lapse of a predetermined interval of time given by a timer circuit, the transistor is turned on to detect whether or not the lamp is still short-circuited. If the lamp is still short-circuited, the transistor is again turned off and then a same sequence of operations will be repeated until it is detected that the short-circuiting of the lamp has been recovered and thus a normal operation of the apparatus is restarted.
