Patent number: 8138905Abstract: A tire pressure warning device having a detection circuit is mounted to an inflation valve on every tire of a car to implement tire pressure detection. First, a microprocessing controller in the detection circuit sends a tire location ID assigned to every tire to a signal receiving circuit provided in a dashboard of the car. Then, the microprocessing controller detects a tire pressure value of the corresponding tire and uses the detected tire pressure value as a standard pressure point for the tire. Thereafter, the microprocessing controller keeps detecting the tire pressure value of the tire. When a detected new tire pressure value is higher or lower than the standard pressure point by a preset percentage, a wireless RF is transmitted to the signal receiving circuit for the latter to identify the tire with high or low tire pressure and emit an alarm while displaying the tire pressure value.Type: GrantFiled: June 17, 2009Date of Patent: March 20, 2012Inventor: Teng-Wen Huang

Publication number: 20080106394Abstract: A multi-port tire pressure detecting system includes a plurality of pressure detection units and a pressure processing unit. Each of the pressure detection units is mounted to an inflation valve on a tire via a tire pressure inlet port, and includes an internal pressure detector and an outward projected pumping inlet port. The pressure processing unit includes a microprocessor, a transmitter, and a power supply connected to the microprocessor, the transmitter, and the pressure detectors for supplying power thereto. When the pressure detectors detect the pressure of tires, tire pressure data are generated. The generated tire pressure data are processed by the microprocessor and then transmitted by the transmitter to a receiving unit near a driver seat for display in real time. When a tire is indicated as having insufficient internal pressure, the tire may be conveniently inflated via the pumping inlet port of a corresponding pressure detection unit.Type: ApplicationFiled: March 5, 2007Publication date: May 8, 2008Inventor: Teng-Wen Huang
