Filed:

May 29, 1996

Appl. No.:

8/655159

Inventors:

Gary Cyras - Folsom CA
Stuart Levy - Phoenix AZ
David C. Scheer - Boca Raton FL

Assignee:

Intel Corporation - Santa Clara CA

International Classification:

G06F 1312

US Classification:

380 49

Abstract:

A method and apparatus for controlling access to a detachably connectable computer device using encryption is disclosed. The method and apparatus include a connector for coupling the device to a computer, an input for receiving a password from a user, encrypting logic for encrypting the password and comparing logic for comparing the received password with a key. The key is determined by encrypting a user-assigned password and storing it as the key. Further included is circuitry for determining whether the received password corresponds to the key, and circuitry for sending an enable signal to configuration logic of the detachably connectable computer device, upon a determination that the received password corresponds to the key.

Abstract:

A sideswipe contact system for an add in PC card consisting of an apparatus for identifying the card as having a sideswipe connector and apparatus on a header for causing the header connectors to be electrically isolated from an inserted PC card unless the PC card is equipped with the sideswipe connectors. The header assembly includes a frame mechanically shaped to receive the card frame in an inserting relationship. A plurality of connector assemblies are movably mounted to the header frame. Each of the connector assemblies consists of an insulating standoff having substantially the same specified shape as the first cavity and fitting therein and a second electrical conductor adjacent to and smaller than the standoff. The plurality of connector assemblies are movable from a first position when the PC card is not inserted in the header frame to a second position when the card is fully inserted into the header. The movement from the first position to the second position is in a direction substantially orthogonal to the long dimension of the PC card.
