The second adapter is provided for being connected to the first adapter of the game controller. The mode selector is provided for outputting one of selection signals. The memory stores different encode data. The conversion circuit selects encode data according to the selection signals output from the mode selector, and encodes and converts the button signal into a pre-formatted wireless signal according to the selected encode data, and then sends the pre-formatted wireless signal through a wireless signal transmitting circuit. Thus, the button signal of the game controller is converted into a wireless signal corresponding to another game console providing another game control device integrating the game controller with the external control device, which has the same effect.

  • Patent number: 10096611
    Abstract: A trapping gate forming process includes the following. An oxide/nitride/oxide layer is formed on a substrate. A hard mask is formed to cover the oxide/nitride/oxide layer. The hard mask, the oxide/nitride/oxide layer and the substrate are patterned to form at least a trench in the hard mask, the oxide/nitride/oxide layer along a first direction. An isolation structure is formed in the trench. A first gate is formed across the oxide/nitride/oxide layer along a second direction orthogonal to the first direction. A flash cell formed by said process includes a substrate, a first gate and an oxide/nitride/oxide layer. The substrate contains at least an active area extending along a first direction. The first gate is disposed across the active area along a second direction orthogonal to the first direction, thereby intersecting an overlapping area. The oxide/nitride/oxide layer is disposed in the overlapping area between the first gate and the active area.

  • Patent number: 9572545
    Abstract: The present invention provides a radiotherapy system that can monitor a target location in real time. The radiotherapy system includes a remote control system operable to actuate a real-time image capturing device to acquire images in real time for monitoring the target location. The system also includes an image registration system that can register the acquired image with an image previously captured for the treatment plan, whereby it can be determined whether the patient's tumor is in the beam's eye view of the treatment plan. By confirming that the tumor is in the range of the beam's eye view, the accuracy of the treatment can be improved, and the irradiated area can be reduced, which makes the radiation treatment safer.
