20100264940 | CAPACITANCE TOUCH SENSING DEVICE AND DOOR LOCKING DEVICE - A capacitance touch sensing device that detects the touch of a user against a surface of a door handle on the outside of a vehicle includes an upper sensor electrode provided in an upper portion of the door handle, a lower sensor electrode provided in a lower portion of the door handle, an upper detecting portion that detects when the user has touched an upper surface of the door handle based on output from the upper sensor electrode, and a lower detecting portion that detects when the user has touched a lower surface of the door handle based on output from the lower sensor electrode. The detection sensitivity of one of the upper detecting portion or the lower detecting portion is lower than the detection sensitivity of the other. | 10-21-2010 |
20120007724 | REMOTE CONTROL SYSTEM AND MOBILE DEVICE - A remote control system includes a mobile device and a receiver connected to a control target. The mobile device includes an input unit accepting user's input operation; an operation signal transmission unit wirelessly transmitting an operation signal corresponding to the input operation during the input operation; a frequency switching determination unit determining whether to switch the transmission frequency band from a first frequency band to a second frequency band based on at least any one of a manner of the input operation and a state of wireless communication; and a transmission frequency switching unit switching the transmission frequency band when the frequency switching determination unit determines to switch the transmission frequency band. The receiver includes an operation signal reception unit receiving the operation signal; and a control unit controlling the control target on the basis of the received operation signal. | 01-12-2012 |

20130029623 | RADIO COMMUNICATION SYSTEM, RECEIVER, AND COMMUNICATION METHOD - A radio communication system includes: a receiver that is configured to receive a first radio wave sent according to a remote keyless entry system and a second radio wave sent according to a tire pressure monitoring system; and a reception mode switching unit that sets a reception mode of the receiver to a first reception mode, in which the first radio wave is received, when an ignition switch of a vehicle is off, and sets the reception mode to a second reception mode, in which the second radio wave is received, when the ignition switch of the vehicle is on. If the reception mode switching unit receives a first request to set the reception mode to the first reception mode while the reception mode is set to the second reception mode, the reception mode switching unit sets the reception mode to the first reception mode. | 01-31-2013 |
20130089066 | WIRELESS COMMUNICATION SYSTEM AND COMMUNICATION METHOD FOR WIRELESS COMMUNICATION SYSTEM - A mobile device includes a transmitting unit that, each time an ON operation of a switch in a first mode is performed, transmits a wireless signal corresponding to the first mode ON operation by changing a frequency band among three or more frequency bands and that, when an ON operation of the switch in a second mode is performed, transmits a wireless signal, corresponding to the second mode ON operation, in the frequency band selected at that time. The transmitting unit includes a frequency band computing unit that selects one of the three or more frequency bands through a computation for changing a communication environment when the second mode ON operation of the switch is repeatedly performed. A receiver of the in-vehicle device receives a wireless signal transmitted from the transmitting unit and recognizes command information allocated in advance in correspondence with each ON operation mode of the switch. | 04-11-2013 |
20130181824 | VEHICLE RECEIVER SYSTEM, VEHICLE RECEIVER, AND OPERATING METHOD FOR VEHICLE RECEIVER - A vehicle receiver system includes: a receiver provided in a vehicle cabin, wherein an operating mode of the receiver includes a first mode for receiving a first wireless signal transmitted from a portable key, and a second mode for receiving a second wireless signal relating to a tire air pressure, transmitted from a transmitter provided on a tire; and a key verification device that performs key verification on the portable key in the vehicle cabin on the basis of the first wireless signal. In a predetermined situation, the receiver is configured such that the operating mode of the receiver is switched between the first mode and the second mode, and proportion of a second mode operation time in which the receiver operates in the second mode is set to be greater when a vehicle speed is relatively high than when the vehicle speed is relatively low. | 07-18-2013 |
20130225093 | WIRELESS COMMUNICATION METHOD AND WIRELESS COMMUNICATION APPARATUS - A wireless communication method is provided. This method includes: selecting one of a plurality of predetermined frequency bands each time a switch operation is manually performed in a transmitter, and then using the selected frequency band to transmit a radio signal corresponding to the switch operation for a predetermined specified transmission time; in a receiver apparatus, receiving the transmitted wireless signal, and then recognizing the content of a command that has already been assigned in accordance with the switch operation; and defining an intermittent reception standby period, which is repeated at a predetermined cycle for each of the frequency bands. | 08-29-2013 |
20140184398 | REMOTE CONTROL SYSTEM AND MOBILE DEVICE - A remote control system includes a mobile device and a receiver connected to a control target. The mobile device includes an input unit accepting user's input operation; an operation signal transmission unit wirelessly transmitting an operation signal corresponding to the input operation during the input operation; a frequency switching determination unit determining whether to switch the transmission frequency band from a first frequency band to a second frequency band based on at least any one of a manner of the input operation and a state of wireless communication; and a transmission frequency switching unit switching the transmission frequency band when the frequency switching determination unit determines to switch the transmission frequency band. The receiver includes an operation signal reception unit receiving the operation signal; and a control unit controlling the control target on the basis of the received operation signal. | 07-03-2014 |
