Abstract:
Several systems for tracking one or more radiation blocking objects on a surface are disclosed. A pair of radiation sensors are provided adjacent the surface and a plurality of radiation sources are provided adjacent the surface. Radiation from at least some of the radiation sources travels across the surface to reach each of the radiation sensors. One or more radiation blocking objects on the surface attenuate radiation from one or more radiation sources from reaching each of the sensors. The position of the one or more radiation blocking objects is estimates and may be tracked based on the position of the one or more attenuated radiation sources relative to each radiation sensor.

Claim (Index 1):
A system for sensing the position of a radiation blocking object, the system comprising:\n a frame; a plurality of radiation sources mounted to the frame; a first radiation sensor mounted to the frame, wherein the first radiation sensor is responsive to the intensity of radiation emitted by at least some of the radiation sources and incident on the first radiation sensor to provide a first series of radiation intensity levels; a second radiation sensor mounted to the frame, wherein the second radiation sensor is responsive to the intensity of radiation emitted by at least some of the radiation sources and incident on the second radiation sensor to provide a second series of radiation intensity levels and wherein the first and second radiation sensors are spaced by a distance; a controller coupled to radiation sources and the radiation sensors, wherein the controller is configured to:\n sequentially and individually activate at least some of the radiation sources; \n identify a first set of one or more attenuated radiation intensity levels in the first series of radiation intensity levels; \n estimate a first angle relative to the first radiation sensor corresponding to the first set of one or more attenuated radiation intensity levels; \n identify a second set of one or more attenuated radiation intensity levels in the second series of radiation intensity levels; \n estimate a second angle relative to the second radiation sensor corresponding to the second set of one or more attenuated radiation intensity levels; and \n estimate the position of the radiation blocking object based upon the distance, the first angle and the second angle.
