A portable equipment detecting system includes an antenna having a first element of which a longitudinal direction is defined as a running direction of the vehicle, a second element of which longitudinal direction is defined as a direction perpendicular to the running direction of the vehicle and the vertical direction of the vehicle, and a bypass wiring of which one end is connected to a connection point between the first and second elements; and detecting circuit adapted to switch between three power-supplied states of the antenna including a first supplied state, a second supplied state and a third supplied state, and to detect a location of the portable equipment based on an acknowledge signal from the portable equipment when the power-supplied state is switched.

The mobile communication terminal has a main body unit and an attachment. When the main body unit separates from the attachment, the attachment transmits a predetermined radio signal. The main body unit receives the radio signal and determines whether its distance from the attachment exceeds specified distance. When the main body unit is at a distance from the attachment exceeding the specified distance, predetermined operation of the main body unit, for example, entering operation using a keypad, memory read-out operation, data transmission and data reception, are disabled. In this manner, it is possible to prevent unauthorized use by third parties or information leaks to third parties when the main body unit has been lost.

According to one embodiment, a wireless control system having an electronic device with a wireless communication function and a remote control module for remotely operating the electronic device, wherein the remote control module includes a control module. A control module configured to transmit a authentication information to a other device via a proximity communication module and receive remote control command information for remotely operating the other device from the other device via the proximity communication module so as to store it in a storage module in order to allow the other device to start a process for establishing wireless connection with the electronic device based on the authentication information.

A vehicle-side unit transmits a first request signal WAKE periodically toward a portable unit, and transmits a second request signal CHLG at every predetermined transmission interval specific to the vehicle-side unit upon reception of a first response signal ACK from the portable unit in response to the transmitted WAKE. The portable unit is operable with power supplied from a battery. The portable unit transmits ACK upon reception of WAKE and becomes ready for reception of CHLG at a timing CHLG is transmitted in accordance with the transmission interval specific to the vehicle-side unit.

An on-board information system is provided, including a help facility, which is operable to provide information to a requester. The information comprises audio or audio-visual descriptions for operating various systems and control devices, using on-board or off-board devices. An information system is provided, comprising a requestor-initiated information inquiry device, an information storage system, and, an information communications center. The information storage system communicates information to the communications center based upon a request for information initiated by the requester to the information inquiry device. The request for information can be canceled during delivery. The system is applicable to vehicles and other systems wherein operators may have limited knowledge of functioning of all aspects of the system.

The invention relates to a television press key lock and release method which adopts the following method: 1) storing the press key lock and release order code in the television main control definite storage. 2) Setting a press key of the remote controller to trigger the circuit to send the lock order to the main control unit. 3) Comparing and ascertaining the lock order and the definite storage press key lock or release order code and sending the lock order and calling the release program to start running. 4) The release subprogram compares the keyboard order and other interfering signal, ifthey are different with the release code, it filters them. 5) It recovers the connecting channel between the order information receiving module and the order processing module and jumps out of the subprogram after comparing the signal form the combined key to ascertain the release code.
