Patent number: 5526662Abstract: A combination key-like device and electrical receptacle for the key-like device wherein the receptacle defines electrical contact surface areas for mating with corresponding contact surface areas defined by the key-like device. At least one clip defines the electrical contact surface areas for the said receptacle and the clip is supported on the receptacle body. A keyway opening is defined by the body and the clip comprises a transverse portion and a pair of legs extending outwardly from the transverse portion with contact elements defined by each of the legs extending inwardly toward the keyway opening and with openings defined by the body communicating with said keyway opening for receiving the contact elements. A contact band is carried by the key-like device whereby insertion of the key-like device into the keyway opening brings the contact band into electrical contact with at least one of the contact elements.Type: GrantFiled: December 28, 1993Date of Patent: June 18, 1996Assignees: Duncan Industries Parking Control Systems Corp., Datakey, Inc.Inventors: Robert R. Diekhoff, Joseph H. Sutton, Hazem Hassan, Michael Boehner

Patent number: 4752679Abstract: An improved receptacle for a key-like device containing an embedded electronic circuit component with electrical leads extending to the surface of the key to form electrical contact areas thereon. The receptacle defines a keyway in which a plurality of exposed contact pins are positioned and spaced inside the receptacle to correspond to the spacing of the electrical contact areas on the key-like device for mating therewith upon insertion of the key device. The receptacle includes a protection sleeve which functions as a guard means for the contact pins. The receptacle is designed to be combined with a printed circuit board by insertion of the outer ends of the contact pins, wich extend through and out of a side of the receptacle, into the circuit board. The contact pins may be received into a variety of predetermined patterns of connectors on the circuit board facilitating electrical connection of the receptacle contact pins to a variety of standardized electrical connectors.Type: GrantFiled: March 2, 1987Date of Patent: June 21, 1988Assignee: Datakey, Inc.Inventor: William H. Wehrmacher

Patent number: 4436993Abstract: An improved electronic key for use in combination with an electrical receptacle adapted to receive the key wherein switch contacts on the key are designed for making electrical contact with corresponding receptacle contacts when the key is turned in the receptacle to an "on" position only after the other key contacts make electrical contact with the corresponding receptacle contacts. Conversely, the switch contacts are the first to break electrical contact when the key is turned past the "on" position in either direction.Type: GrantFiled: January 11, 1982Date of Patent: March 13, 1984Assignee: Datakey, Inc.Inventor: William P. Flies

Patent number: 4379966Abstract: Receptacle for a key-like device containing an embedded micro-electronic circuit component with leads thereto extending to the surface of the key. The receptacle defines a keyway in which a plurality of contact heads spaced to correspond to the spacing of the leads on the key are positioned. The contact heads are supported by finger-like spring members which provide inwardly directed pressure against the contact heads when the key leads are brought into engagement with the contact heads. A flexible circuit surrounding the finger spring members and connected to the receptacle contact heads provides means for connecting the micro-electronic circuit in the key with a control circuit such as a computer.Type: GrantFiled: July 23, 1981Date of Patent: April 12, 1983Assignee: Datakey, Inc.Inventor: William P. Flies

Patent number: 4326125Abstract: This invention relates to improvements in the functional design of electrical key-like devices and electrical receptacles for use in combination therewith. Electronic circuitry systems, such as computers and other operating circuits, interface with the key-like devices through the receptacle. The keys contain a microelectronic circuit element, e.g., a microelectronic circuit chip or die, having an electrical lead or leads exposed along the length of the key for contacting electrical leads in the receptacle when the key is inserted therein and rotated to a "locked" position. The keys are particularly designed to interface with a processor and program memory system, that is, a computer.Type: GrantFiled: June 26, 1980Date of Patent: April 20, 1982Assignee: Datakey, Inc.Inventor: William P.
