摘要:
A remote-controlled starter apparatus is used in a machine having a power supply system and a power mechanism interconnected via a power conducting line. The starter apparatus includes a starter control circuit, a current sensing circuit and a signal converting circuit. The starter control circuit starts the power mechanism upon receiving a start-initiate signal transmitted by a remote controller, and generates a signal to activate the current sensing circuit. The current sensing circuit generates a sensor output corresponding to electrical current flowing through the power conducting line. The signal converting circuit is connected to the current sensing circuit and the starter control circuit, and converts the sensor output into a corresponding voltage output to enable the starter control circuit to determine whether or not the starting operation was successful, and to restart the power mechanism upon determining that the starting operation was unsuccessful.

A method for correcting azimuth angle data of a navigational device, which is installed in a vehicle, includes the steps of enabling the navigational device to periodically receive a position information signal that is transmitted from a global positioning system (GPS) service provider and that contains an azimuth angle of the vehicle, obtaining velocity data of the vehicle, obtaining magnetic north data by means of an electronic compass, and enabling the navigational device to correct the azimuth angle contained in the position information based on the magnetic north data when the velocity data is lower than a reference value. A navigational device that implements the aforesaid method is also disclosed.

A wireless intercommunicating apparatus includes a wireless intercommunicating device capable of outputting an audio signal corresponding to an incoming radio frequency signal received thereby, and a driving signal generated upon detecting generation of the audio signal. An auxiliary device is coupled to the wireless intercommunicating device, and includes an earphone switch port switched so as to enable an earphone to reproduce the audio signal from the wireless intercommunicating device when the earphone is connected to the earphone switch port, and a signal indicating unit driven by the driving signal from the wireless intercommunicating device so as to indicate receipt of the incoming radio frequency signal by the wireless intercommunicating device.

A safety device for a remotely-activated power supplying system of a manual transmission vehicle includes a starting safety unit connected to a main controller for detecting the presence of a safety condition, and an ignition key detector connected to the main controller for detecting if an ignition key is uprooted from a key-operated power supplying system. Thus, the main controller can be configured to activate a power supplying device to supply electric power to an ignition system when a wirelessly transmitted start signal is received by the main controller, when the safety condition is detected by the starting safety unit, and when the ignition key detector detects that the ignition key is uprooted.

A vehicle security system includes a detector circuit cluster, an alarm circuit cluster and a host device, all connected to a common power supply line. The detector circuit cluster includes a detector circuit for detecting a current state of a respective component of the vehicle. The detector circuit can receive a status request signal and transmit a status response signal corresponding to the detected state of the respective component. The alarm circuit cluster is enabled upon receipt of an alarm enable signal for generating an alarm output. The host device can transmit the status request signal for the detector circuit, receive the status response signal from the detector circuit, and selectively transmit the alarm enable signal in accordance with the status response signal.
