Filed:

Oct 26, 1994

Appl. No.:

8/330250

Inventors:

Michael E. Pierce - Orangevale CA
David C. Scheer - Boca Raton FL

Assignee:

Intel Corporation - Santa Clara CA

International Classification:

G06F 132

US Classification:

395750

Abstract:

A system for controlling the power consumption of an add-in PC card operating within a host computer. The host computer includes a power supply that provides all power used by the PC card. The PC card includes communication registers required for communication between the host computer and the PC card. The PC card also includes a microcontroller connected to an I/O subsystem and a multi-pin I/O connector. A first side of the multi-pin I/O connector is connected to the I/O subsystem and a second side is connected to a source of I/O signals external to the host computer. An external register module is connected to the microcontroller and communicates with the host computer. The external register module contains the communication registers. A status detector located on the PC card detects whether the I/O subsystem is processing I/O information, and supplies a status signal indicative thereof. A power management module is also located on the PC card and is connected to the status connector.

Abstract:

A modem located on a PC card. An I/O socket is mounted on one end of the PC card and sideswipe contacts are positioned long e one or more sides. The I/O socket has a plurality of positions including one or more positions which are electrically connected to the modem. A relay is located in the PC card, and has one side connected in common to the modem and the positions on the I/O socket. The other side of the relay is connected to the sideswipe connectors. The control input to the relay is connected to a position of the I/O socket separate from the modem positions. A voltage source is connected to a position in the socket separate from the modem positions and the control signal position. An I/O plug is designed to have one side connected to the telephone network and the other side connected to the I/O socket such that all pins in the plug mate with the corresponding positions in the I/O socket. The I/O plug contains a lead interconnecting and creating a short circuit between the pin in the I/O plug which mates with the position in the I/O socket connected to the control input of the relay and the pin in the I/O plug which mates with the position in the socket connected to the voltage source.

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.

US Classification:

2502221

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.
