RFID wireless computer mouse
View Patent ↗An RFID wireless computer mouse system, comprising: a mouse having a single passive RFID circuit in signal communication with a computer having an RFID reader. The single passive RFID circuit operates the mouse such that the mouse provides signals indicative of X-Y coordinates to move a cursor on a display screen of the computer without the use of an internal or an external power source.
1. An RFID wireless computer mouse system, comprising:
a mouse comprising:
a ball configured to move in an x-direction and a y-direction;
an x-axis wheel and a y-axis wheel each configured to rotate in response to the movement of the ball, the x-axis wheel translates the motion of the ball in the x-direction while the y-axis wheel translates the motion of the ball in the y-direction;
a first set of sensing devices and a second set of sensing devices, the first set of sensing devices detects the motion of the ball in the x-direction based on the movement of the x-axis wheel while the second set of sensing devices detects the motion of the ball in the y-direction based on the movement of the y-axis wheel; and
a single passive RFID circuit coupled 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
an RFID reader in signal communication with the single passive RFID circuit, the RFID reader decodes the stream of bits and converts the stream of bits into corresponding x-coordinates and y-coordinates used to move a cursor on a display screen of a computer, 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.
