  • Patent number: 8175983
    Abstract: A communication system has: a portable communication device; and an in-vehicle communication device that communicates with the portable communication device through synchronous communication. The potable communication device transmits dummy signals simulating the vehicle information to the in-vehicle communication device in a first period. The in-vehicle communication device learns and records a first filter coefficient for filtering the dummy signals that are received in the first period and a second filter coefficient for filtering signals that are received from the sensors in a second period in which the portable communication device do not transmit the dummy signals, and the in-vehicle communication device calculates a third filter coefficient for removing noises on signals received from the sensors based on the first and second filter coefficients and then filters the received signals using the third filter coefficient.

  • Publication number: 20120064830
    Abstract: A frequency switching terminal is provided to input a signal for switching frequencies of a reception circuit. A smart ECU is connected to the frequency switching terminal via a connection cable. When the signal for switching the frequencies is inputted into an external input terminal of the reception circuit from the smart ECU via the frequency switching terminal, the reception circuit receives a first electric wave transmitted from a portable terminal for smart entry. In contrast, when the signal for switching the frequencies is not inputted into the external input terminal of the reception circuit from the smart ECU via the frequency switching terminal, the reception circuit receives a second electric wave transmitted from a tire sensor.

  • Patent number: 8132994
    Abstract: A punching processing unit punches holes in a paper bundle delivered from a preprocessing device. A bookbinding unit includes a cartridge for stocking a plurality of rings, and performs a ring binding by binding the paper bundle with the rings. A detecting unit detects an abnormality of a ring in the cartridge. A control unit exchanges a signal with the preprocessing unit each time when detection information obtained by the detecting unit changes. When any one of the rings is determined as abnormal and an execution of ring binding is set, the control unit inhibits the ring binding.

  • Publication number: 20120047294
    Abstract: A communication speed control application sets the initial communication mode of the USB controller to a full speed mode through a USB driver. If a data transfer start request is received from a USB device using application and if the requested communication speed is a high speed communication mode, the communication speed mode of the USB controller is changed to a high speed mode through the USB driver. The USB application estimates the transfer rate required for the data transfer to be executed and, if the estimated transfer rate is higher than the full speed mode or the transfer rate resulting from subtraction of a predetermined margin from the full speed, the requested communication speed is set to the high speed or is set to full speed otherwise.

  • Publication number: 20110298580
    Abstract: In an in-vehicle device control system, an in-vehicle device is controlled based on a checkup result of checkup operation, in which a checkup about a portable device is performed by mutual communication of transmitting a request signal from a vehicle-side unit mounted on a vehicle and transmitting in return a response signal from the portable device in response to the request signal. If the checkup is unsuccessful, the mutual communication is performed again by switching the communication frequency to perform the checkup again. When a user operates a door lock sensor, the vehicle-side unit performs an exterior checkup first. If the checkup is successful, a communication frequency, by which the checkup was performed successfully, is stored in a memory. The vehicle-side unit sets the communication frequency stored in the memory as a communication frequency, which is to be designated to the portable device, for performing an interior checkup next time.
