Patent Images
1. A wireless device comprising:
- a housing;
a substantially radiation transmissive button displaceable relative to said housing;
a fingerprint sensor to capture an image of a fingerprint when the user'"'"'s finger is positioned over the button;
a light source adapted to direct light through said button; and
an optical system to receive light reflected from the user'"'"'s finger over said button, said sensor, said light source, and said optical system adapted to move with said button relative to said housing.

Abstract
A wireless device, such as a remote control unit, may include an internal fingerprint identification unit. The fingerprint identification unit may be arranged to capture the user'"'"'s fingerprint when the user'"'"'s finger is positioned over a button that is substantially radiation transmissive. Radiation directed at the user'"'"'s finger through the button may be captured for image analysis and ultimately for fingerprint identification. Thus, the device may be used to identify users who wish to access a processor-based system such as a processor-based television receiver.

4. A method comprising:
-
providing a wireless device having a substantially radiation transmissive button and a housing such that said button is moveable relative to said housing;
capturing information about the user'"'"'s fingerprint when the user'"'"'s finger is situated over said button by directing a light beam through said mouse button so that said light may be reflected by the user'"'"'s finger and detected within said device;
providing a sensor that produces an image of said user'"'"'s fingerprint and transmits that image from the device to a host computer; and
mounting said sensor to move with said button. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13, 14)

15. A processor-based system comprising:
-
a processor;
a memory coupled to said processor; and
a wireless device coupled to said processor via a wireless link, said device to capture information about an image of a user'"'"'s fingerprint when the user'"'"'s finger is positioned over the device, said device including a substantially radiation transmissive button, a source of illumination which is directed at the button, and an image sensor arranged to detect light from the source when the user'"'"'s finger is positioned over the button, wherein said sensor is mounted to move with said button. - View Dependent Claims (16, 17, 18, 19)
