Patent number: 11985259Abstract: A multi-die device a first die containing a plurality of first die signal path elements configured to propagate a stimulus signal and a second die containing a plurality of second die signal path elements configured to propagate the stimulus signal. The multi-die device further includes an interposer configured to establish signal communication between the first die and the second die so as to deliver the stimulus signal from the plurality of first die signal path elements to the plurality of second die signal path elements to generate a propagation delay. The propagation delay is used to generate a single unified PUF response that is indicative of the authenticity of the multi-die device.Type: GrantFiled: June 24, 2021Date of Patent: May 14, 2024Assignee: RAYTHEON COMPANYInventors: Jennifer E. Howard, Colby K. Hoffman, Edward Escandon, Albert D. Marzullo, Ross MacKinnon, Maegen A. Forrer

Patent number: 8310223Abstract: An electrical probe and associated method are provided to establish electrical contact with a wire. The electrical probe includes an elongate member extending between opposed first and second ends, and first and second needles connected to the elongate member and extending beyond the first end of the elongate member. The electrical probe also includes first and second conductors electrically connected to the first and second needles, respectively, and extending along the elongate member. The electrical probe also includes a bumper stop connected to the elongate member proximate the first end of the tube. Further, the electrical probe includes a movable engagement member extending lengthwise along the elongate member. The moveable engagement member includes a hook that extends beyond the first end of the elongate member and beyond the first and second needles. The hook may include a terminal portion configured to contact the bumper stop.Type: GrantFiled: August 19, 2010Date of Patent: November 13, 2012Assignee: The Boeing CompanyInventors: Edward K. Hoffman, Thomas A. Miller

Patent number: 7249964Abstract: A device for providing strain relief between an electrical connector and a wiring harness having wires or cables already joined to the contacts of the connector includes a T-shaped plate having axial and transverse members and a pair of opposing, inwardly facing, U-shaped structures disposed at opposite ends of the transverse member and extending at a right angle to the plate from a front edge thereof. The device is mounted on the connector with the U-shaped structures respectively straddling a corresponding mounting flange of the connector and a distal end portion of the axial member extending rearward over a portion of the harness extending rearward from the connector. The two rearward extending portions of the plate and harness are cinched together with a strap or the like. The device can be installed after the harness has been assembled without the need to remove the wires or contacts from the connector.Type: GrantFiled: January 31, 2006Date of Patent: July 31, 2007Assignee: The Boeing CompanyInventors: Edward K.

Publication number: 20030036298Abstract: A connector lock for securing and supporting a fully engaged connector assembly against disconnect even when subjected to vibrational forces experienced during launch into outer space. The connector lock includes a base portion and a pair of end portions extending substantially parallel to each other. Each end portion includes a pair of spaced-apart arms formed of flexible material and positioned so as to flex apart as a connector assembly is inserted between the arms. The arms snap back toward their original positions to prevent inadvertent release of the connector assembly.Type: ApplicationFiled: August 20, 2001Publication date: February 20, 2003Applicant: The Boeing CompanyInventors: Edward K. Hoffman, Andrew D. Jackson

Patent number: 6377433Abstract: A fuse/support assembly for attachment to an electrical bus includes a base plate having a substrate made of an insulator, a fastener bore extending through the substrate, and an electrically conductive path on the substrate. There is additionally an external connector structure. A fuse is supported on the substrate and has a first end in electrical communication with the external connector and a second end in electrical communication with the electrically conductive path.Type: GrantFiled: March 17, 2000Date of Patent: April 23, 2002Assignee: The Boeing CompanyInventors: Nancy J. Condon, Edward K. Hoffman, John P. Stafford

Patent number: 6252691Abstract: A wireless intrasatellite communication system is disclosed. Satellite telemetry signals are multiplexed, converted into a digital data stream, and processed by an ASIC to form a multiplexed telemetry data stream. An infrared transceiver transmits the multiplexed telemetry data stream along an optical path to a designated interface that is associated with a remote command and telemetry unit. Telemetry signals are aggregated within a plurality of remote command and telemetry units and transmitted to a central command and telemetry unit via a high-speed digital bus. Command data issued from the central command and telemetry unit is distributed to a designated remote command and telemetry unit, and is routed to the appropriate user unit via the optical path. The user unit processes the command data and generates a responsive command signal output.Type: GrantFiled: June 4, 1998Date of Patent: June 26, 2001Assignee: Hughes Electronics CorporationInventors: Joseph Porzucki, David W. Lloyd, William R. Procopio, Edward K. Hoffman
