  • Patent number: 8045459
    Abstract: 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.

  • Patent number: 7940163
    Abstract: 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.

  • Patent number: 7604469
    Abstract: 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.
