Abstract

A computer keyboard provides for one or more of processing, interfacing, input/output control with respect to the computer and/or one or more devices coupled to the keyboard, and/or for control of one or more devices coupled to the keyboard. The keyboard comprises at least one processor, and may also include one or more busses and/or other devices, that, individually in cooperation, perform such functions. In one embodiment, the processor receives telephony signals from the computer and provides telephony signals to the computer, performing the processing necessary to support telephony functions such as conversion of audio signals. Audio signals from computer sound cards and other audio signal sources may be mixed with telephony signals in keyboards according to the invention. Displays and associated input devices incorporated by the keyboard are provided to control telephony and other keyboard processor functions.

Claims

1. In a keyboard coupled to a computer, the keyboard including an array of switches and a controller coupled to the switches, to provide to the computer signals relating to the state of the switches, the improvement comprising:

a biometric sampling device which generates signals relating to scanning of an image by the biometric sampling device;

a token, the biometric sampling device included within the token, the token being removably attachable to the keyboard so that the biometric sampling device is accessible by a user seeking computer access when the token is attached to the keyboard, wherein when the token is attached to the keyboard, the biometric sampling device is electrically coupled to provide the image-related signals generated by the biometric sampling device for use off the token for authorizing access to a computer.

2. The keyboard of claim 1, wherein the biometric sampling device comprises a fingerprint sampling device.

3. In a keyboard for a computer, the keyboard including an array of switches and a controller coupled to the switches, to provide signals relating to the state of the switches, the improvement comprising:

a fingerprint sampling system for authorizing access by a user to a computer coupled to the keyboard, the fingerprint sampling system mounted on the keyboard;

at least a portion of the keyboard comprising an electrically conductive material, the electrically conductive material electrically coupled to the fingerprint sampling device so as to improve an electrical connection between the fingerprint sampling system and at least a portion of a user'"'"'s body when the user is in contact with the keyboard.
