An ID code learning device includes a RF transceiving module, a received signal strength indication (RSSI) module, and a processing circuit. The RF transceiving module receives RF signals, and each of the RF signals contains an ID code. The RSSI module is electrically connected to the RF transceiving module to detect signal strengths of the RF signals received by the RF transceiving module. The processing circuit is electrically connected to the RF transceiving module and the received signal strength indication module respectively. The received signal strength indication module detects the RF signal with the highest signal strength, the processing circuit pairs the ID code thereof with a predetermined tire location code, and then the RF transceiving module transmits a pairing result out.

A method and device for monitoring video signal transmission includes a signal encoding and transmitting module and the signal receiving module. The signal encoding and transmitting module receives a composite video signal from a video signal source to cut off a horizontal video data series following a predetermined horizontal synchronization signal following a predetermined vertical synchronization signal and add an identification code. The signal receiving module receives the composite video signal carrying the identification code and compares the identification code to transmit the composite video signal out when the identification code is correct.

A packet processing method used in a wireless communication is disclosed to have the packet data not to contain the identification code of the transmitter and to let the receiver read out the correct identification code of the transmitter and verify the effectiveness of the data, assuring excellent confidentiality of the data, reducing packet size, maintaining packet data integrity, extending wireless communication distance and saving power consumption. Under the fix bit error rate, the invention effectively reduces the chance of erroneous data and lowers the current loading to the battery of each of the transmitter and the receiver.

Packet processing method for wireless communications

For installation in the chassis of a car to receive a tire pressure signal from a sensor and transmitter unit wirelessly and to transmit the signal to a display device in the driver's cab of the car through a cable, a receiving antenna for receiving tire pressure signal is disclosed to include a base, a circuit board mounted in the base and spaced the bottom side of the base at a distance over 1 cm, and a top cover covering the base. The circuit board has a metal signal receiving line arranged on the substrate thereof. The signal receiving line has a receiving segment arranged on the top wall of the substrate near one end and extending around a rectangular area of the top wall a number of turns from an inner side toward an outer side, a lead-out segment extending from the outer end of the receiving segment to a predetermined distance in direction toward the other end of the substrate, and a connection segment extended from the lead-out segment to a connection terminal at the second end of the substrate and having a width greater than the lead-out segment.

A tire pressure monitoring system includes receiving antennas installed in a vehicle corresponding to vehicle wheels, a monitoring main unit disposed near a driver's seat, tire pressure sensors respectively installed in the wheels of the vehicle to wirelessly transmit detected data in the form of a data packet for being received by one corresponding adjacent antenna, and a signal combining circuit formed of multiple combiners and having multiple input terminals electrically connected to the receiving antennas and an output terminal electrically connected to the monitoring main unit for combining data packets received from the receiving antennas and transmitting the combined data signal to the monitoring main unit by means of a wired transmission path.

Tire pressure monitoring system

The present invention is a tire pressure monitoring system (TPMS) with a capped tire valve. The system includes a baseplate, a signal transmitter, a cap, and an antenna. The antenna is assembled at the bottom of the baseplate, and also positioned outside the connecting end of the baseplate. Thus, the volume of TPMS is considerably reduced, providing resistance to collision and pollution with improved applicability.

A signal transmission device is used for connection between a first electrical connector at a truck-tractor of a towing vehicle and a second electrical connector at a trailer of the towing vehicle. The signal transmission device includes first and second magnetic holders, third and fourth electrical connectors mounted to the first and second magnetic holders respectively, a stretchable coil tube, and a cable. The first magnetic holder is adapted to be attached to the truck-tractor and the second magnetic holder is adapted to be attached to the trailer. The third electrical connector is adapted for connecting the first electrical connector at the truck-tractor and the fourth electrical connector is adapted for connecting the second electrical connector at the trailer. The cable is spirally inserted through the stretchable coil tube and provided with two ends electrically connected with the third and fourth electrical connectors.

The present invention provides a wireless tire pressure and tire temperature detecting system, using a wireless monitoring and transmission device with a centrifugal switch. When the tire rotational speed of the car reaches a certain speed, it turns on the centrifugal switch. The centrifugal switch is used to turn on the entire wireless monitoring and transmission device to detect, process signal, and transmit. The wireless monitoring and transmission device is not working, until the tire rotational speed of the car reaches a certain speed before it is initiated and causes power consumption. The present invention saves more power consumption than the conventional structure, which extends the shelf life of the wireless tire pressure and temperature detecting system as well as time involved to change the battery, which is practical and convenient.
