The connector is connected coaxially on the valve stem and is conductive and has a connecting section. The connecting section has an adjusting slot and a domical end. The adjusting slot is formed through the connecting section. The tire pressure detector has at least one tab and at least one conducting washer, the at least one tab protrudes from the tire pressure detector, corresponds to and is adjustably mounted on the connecting section. The at least one tab has a tab slot being formed therethrough. A bolt assembly is mounted in the tab slot and the adjusting slot to hold the tire pressure detector on the connector.
Abstract:
A position data exchange system comprises first and second mobile communication devices. The first communication device retrieves current coordinates of itself from a Global Positioning System (GPS) receiver and transmits the coordinates through a wireless communication channel from which the second communication device receives the coordinates. The second communication device displays data concerning the current location of the first communication device according to the coordinates and further provides navigation.
Abstract:
A wireless tire pressure sensing device, a method for setting a standard tire pressure thereof and a wireless tire pressure sensing activation device adjust the tire pressure of each tire in a vehicle to a standard tire pressure according to a requirement of the vehicle after the wireless tire pressure sensing device is mounted in each tire, maintain each tire at the standard tire pressure for a preset time period or employ the wireless tire pressure sensing activation device to transmit a setup instruction to the wireless tire pressure sensing device to set a current tire pressure as the standard tire pressure. The wireless tire pressure sensing device can be set up with the standard tire pressure and conveniently modified. As no threshold value of tire pressure needs to be pre-stored, wireless tire pressure sensing devices with different threshold values are not necessarily prepared beforehand, thereby effectively lowering the stocking pressure on inventory management.
Abstract:
An anti-interference antenna of a wireless tire pressure receiver has an insulating cable having a main casing and a sub-casing connected side by side with the main casing. The main casing has a power cable longitudinally mounted through the main casing. The sub-casing has an antenna longitudinally mounted through the sub-casing. As the antenna is individually sleeved by the insulating sub-casing, the antenna and the power cables are isolated to prevent from interfering with each other. Besides, the insulating cable further has at least one air channel longitudinally formed through the corresponding cable and mounted with a metal layer on an inner wall of the air channel, around the power cable, around each of power wires in the power cable, or around the power cable and the air channel, and filled with an EMI-shielding matter to further isolate the antenna and the power cables.
Abstract:
A tire pressure detecting apparatus has a micro-controller, a detecting module and a transceiver. The detecting module is electronically connected to the micro-controller and has a tire pressure detecting unit being controlled by the micro-controller to detect a tire pressure inside a tire. The transceiver is electronically connected to the micro-controller, transmits a high frequency signal corresponding to detected characteristic tire parameters from the detecting module to a monitoring system inside a car and receives an external high frequency signal sent from external tire pressure detecting apparatus for the micro-controller, the micro-controller temporarily delaying sending of the high frequency signal until a waiting time has expired to prevent signal collision between the high frequency signal and the external high frequency signal.
Abstract:
A tire pressure detecting apparatus has an identification rewriteable tire pressure detector and a setting apparatus. The tire pressure detector is securely mounted on a valve stem inside a tire of a vehicle and has a micro-processing module, a sensing module, a transmitting module and a receiving interface, where the micro-processing module has a memory unit. The setting apparatus is capable of reading or inputting an identification from a failure tire pressure detector, transmits the identification to the identification rewriteable tire pressure detector and writes the identification into the memory unit.
