Publication number: 20200277814Abstract: A releasable ball lock hinge is disclosed. The releasable ball lock hinge includes a first body operable with a hinge ball and a release ball. Each ball can be movable within respective openings of the first body. The releasable ball lock hinge also includes a second body configured to rotatably interface and removably couple with the first body. The hinge ball releasably engages the second body. The second body has a release recess operable with the release ball to disengage the hinge ball and alternately couple and release the first body and the second body based on a relative position between the first body and the second body.Type: ApplicationFiled: December 31, 2019Publication date: September 3, 2020Inventors: Gregory E.

Patent number: 9191587Abstract: An optical imaging system and method in which a second channel is used to provide alignment data for achieving image frame stacking of image data in a first channel. In one example, image stacking of infrared images is achieved by obtaining and analyzing corresponding visible images to provide alignment data that is then used to align and stack the infrared images.Type: GrantFiled: October 26, 2012Date of Patent: November 17, 2015Assignee: RAYTHEON COMPANYInventors: Richard J. Wright, William R. Owens, Gregory E. Longerich, Andrew F. Varecka, Perry H. Frahm, David C. Robillard, Emerald J. Adair

Patent number: 9039210Abstract: A variable length light shield is disclosed for an electro-optical sensor within a nose cone. The light shield includes a base, a telescopic shade supported by the base, and a ring rotatably supported about the base. The light shield also includes a guide tube disposed proximate the ring with an end extending away from the ring about a side of the telescopic shade. The light shield further includes an extension spring supported by the guide tube with an end coupled to the telescopic shade. Additionally, the light shield includes a cable extending through the guide tube and the extension spring, with one end of the cable coupled to the ring and another end of the cable coupled to the telescopic shade. The extension spring is configured to exert a force on the telescopic shade to extend the telescopic shade. Rotation of the ring causes retraction of the telescopic shade.Type: GrantFiled: January 4, 2013Date of Patent: May 26, 2015Assignee: Raytheon CompanyInventors: Gregory E. Longerich, William Owens, Richard J. Wright, David C. Robillard, Emerald J. Adair, Perry H. Frahm

Patent number: 8984205Abstract: A system includes an interface with a plurality of sub-addresses. The interface receives critical data and non-critical data. The critical data are received only at more specific sub-addresses of the interface. The interface transfers the critical data received at the sub-addresses to a critical processor, such that the critical data avoids being received by or being processed by a non-critical processor. The interface transfers the non-critical data from the interface to the non-critical processor. The configuration of the interface is hard-coded such that the configuration of the interface is fixed at power up of the interface and is non-changeable by the non-critical processor. The interface includes an external platform interface that is external to the critical processor, the non-critical processor, and a local controller. The external platform interface includes a limited ability to store the critical and non-critical data.Type: GrantFiled: March 22, 2012Date of Patent: March 17, 2015Assignee: Raytheon CompanyInventors: David C. Robillard, Joseph D. Wagovich

Patent number: 8412482Abstract: An electronic acceleration switch, such as for arming and firing a squib, for instance used in arming a warhead, safe missile air, ground and sea launch separation arming, includes multiple redundancies to provide a fail-safe system that does not have a single-point failure. The switch includes different channels, each of which includes a power subsystem, multiple accelerometers, a pair of controllers, and a switching circuit. The power subsystems of the two channels provide power to multiple accelerometers of each channel. The accelerometers of each channel may include a mix of digital and analog accelerometers. The acceleration sensors can be either one-axis or three-axis sensors. The accelerometers are connected to the controllers of both channels. The controllers provide redundancy for each channel. In addition, the controllers include voting logic that receives inputs from the accelerometers, and determines whether to send arm and enable signals to the multiple squib drivers.Type: GrantFiled: December 3, 2009Date of Patent: April 2, 2013Assignee: Raytheon CompanyInventors: David C.
