  • Publication number: 20230380008
    Abstract: A User Equipment (UE) including a wireless transceiver and a controller is provided. The wireless transceiver performs wireless transmission and reception to and from a first service network utilizing a first RAT or a second service network utilizing a second RAT. The controller sends an indicator of a connection release request to the first service network via the wireless transceiver in response to terminating a first communication service with the first service network or in response to leaving the first service network for the second service network. Also, the controller releases a Radio Resource Control (RRC) connection with the first service network after sending the indicator of the connection release request.

  • Patent number: 10014251
    Abstract: A semiconductor device with the metal fuse is provided. The metal fuse connects an electronic component (e.g., a transistor) and a existing dummy feature which is grounded. The protection of the metal fuse can be designed to start at the beginning of the metallization formation processes. The grounded dummy feature provides a path for the plasma charging to the ground during the entire back end of the line process. The metal fuse is a process level protection as opposed to the diode, which is a circuit level protection. As a process level protection, the metal fuse protects subsequently-formed circuitry. In addition, no additional active area is required for the metal fuse in the chip other than internal dummy patterns that are already implemented.

  • Patent number: 9463673
    Abstract: A tire positioning method includes the following steps. Four wireless signals transmitted from four tires of a car are received by a wireless signal receiver. Each wireless signal includes a uniaxial acceleration. One of the tires which is located at a first location is identified according to the intensity of the wireless signals. The first location is the closest to the wireless signal receiver. When the car makes a turn, one of the tires which is located at a second location is identified according to the direction of each uniaxial acceleration. The second location and the first location are both located at one side of the car. The direction of the uniaxial acceleration of the tire which is located at the first location is identical to that of the tire which is at the second location. The side of the car is right side or left side.
