Patent number: 7940163Abstract: A wireless tire pressure monitoring system includes a monitoring main unit installed in the truck-tractor of a towing vehicle, a receiving antenna electrically connected to the monitoring main unit, and a register set in a location within the wireless communication transmission range of the receiving antenna and stored with an ID code and location code of each sensor at each wheel of the platform of the towing vehicle. When the register receives a triggering signal containing an identification code of the monitoring main unit, the register compares and matches the identification code and the location code of every wheel of the platform with the identification code of the monitoring main unit and then sends matched data in the form of a wireless packet to the receiving antenna for enabling the monitoring main unit to recognize the installation location of every wheel of the platform of the towing vehicle.Type: GrantFiled: December 10, 2008Date of Patent: May 10, 2011Assignee: Mobiletron Electronics Co., Ltd.Inventors: Shiao-Hwa Huang, Ming-Kaun Liao, Yu-Chang Tsai

Patent number: 7604469Abstract: A degating device applied to remove a cull between two chip carriers comprises a lower mold, an upper mold, a blowing-opening, and a cooling pipe. The lower mold is used to load chip carriers and has a plunger set for propping and degating the cull. The upper mold is fit in with the lower mold tightly. The airflow blown out from the blowing-opening blows to lower the temperature around the chip carriers. The cooling pipe is disposed according to the position of the blowing-opening to cool down the temperature around the blowing-opening. The two chip carriers are disposed on the lower mold and fixed between the upper mold and the lower mold while the upper mold combines with the lower mold. By changing the position of the plunger set relative to the upper mold and the lower mold, the cull can be stripped from the chip carriers.Type: GrantFiled: January 9, 2007Date of Patent: October 20, 2009Assignee: Advanced Semiconductor Engineering, Inc.Inventors: Yun-Lung Chang, Chin-Sung Lee, Chia-Ming Chang, Yu-Chang Tsai
