Abstract:
1. A method for moving a cursor on a display screen of a computer, comprising: translating the motion of a ball of a mouse utilizing an x-axis wheel and a y-axis wheel, the ball configured to move in an x-direction and a y-direction, the x-axis wheel translates the motion of the ball in the x-direction wheel while the y-axis wheel translates the motion of the ball in the y-direction; detecting the motion of the ball in the x-direction based on the movement of the x-axis wheel utilizing a first set of sensing devices and detecting the motion of the ball in the y-direction based on the y-axis wheel utilizing a second set of sensing devices; coupling a single passive RFID circuit to the first set of sensing devices and the second set of sensing devices, the single passive RFID circuit receives a plurality of sensor inputs correspondingly from the first set of sensing devices and the second set of sensing devices indicative of the motion of the ball in the x-direction and the y-direction respectively, and the single passive RFID circuit stores the plurality of sensor inputs in a shift register as a stream of bits and serially shifts and transmits the stream of bits one bit at a time over an antenna of the single passive RFID circuit; and decoding the stream of bits and converting the stream of bits into corresponding x-coordinates and y-coordinates used to move the cursor on the display screen of the computer utilizing an RFID reader, the RFID reader being in signal communication with the single passive RFID circuit, the single passive RFID circuit and the RFID reader move the cursor on the display screen of the computer, wherein the mouse operates without the use of an internal or a conventional power source.
