Abstract: The invention provides a visual feedback system installed between a game host system and an optical gun. It is used to extract a bullet falling point signal or bullet coordinate signal sent from the optical gun to the game host. If the extracted signal is a bullet falling point signal, a control circuit then uses the horizontal synchronous signal H_sync and the vertical synchronous signal V_sync of the video frequency signal to compute the coordinates of the bullet. The coordinate data are sent to an image synthesis circuit, which combines an aiming point cursor on the corresponding coordinate data with the video signal transmitted from the game host and outputs the synthesized image on the display screen.

Abstract: This present invention relates to a button control for use in game controllers. When the button is pressed down, the angle and magnitude of the force of each depression will determine the amount of contact between the conducting jell and the resistor strip or the conducting tracks located on the printed circuit board and thereby determine the magnitude of the output signals so as to gain greater game control. Further, when said resistor strip is made a cut-open, discontinuous structure, then when the conducting jell begins to press on the resistor strip, the resistance changes from infinite resistance to maximum resistance to facilitate reading of button control status.

Abstract: The present invention comprises at least a serial data interface unit, a data buffer unit, a data processing unit, and a serial/parallel data interface unit. It is designed for compressing and transferring recorded data signals stored in the memory card employed by various game players currently available in the market; and acting as a data-transfer device for compressing and transferring data signals and for transmitting control signals between the specific game player and the non-specific memory card.

Abstract: A data compression device includes a data compression circuit for compressing data being transferred between a TV game player and a memory card, and for decompressing data sent from the memory card to the game player. The device is arranged to be inserted into the card receptacle of the TV game player, and includes an opening for receiving the memory card, thereby serving as an adapter between the game player and the memory card.
