Patent number: 10023054Abstract: A power distribution system comprises a plurality of energy storage modules coupled in series. A plurality of electrically isolated power converters are each coupled across one or more of the energy storage modules. When enabled, the power converters provide a low voltage output to an output of the power distribution system. A control system controls the power converters to provide the low voltage output. The control system selectively enables the power converters to balance states of charge of the energy storage modules.Type: GrantFiled: February 17, 2016Date of Patent: July 17, 2018Assignee: Kitty Hawk CorporationInventor: Geoffrey A.

Patent number: 9772466Abstract: Various embodiments provide a system for moving optical elements. The system includes a first rotor and a second rotor configured to rotate in opposite directions. The system further includes a first plurality of paddles coupled to the first rotor, each of the plurality of paddles having an aperture configured to receive a first optical element, and a second plurality of paddles coupled to the second rotor, each of the plurality of paddles having an aperture configured to receive a second optical element. The first rotor and the second rotor are configured to move the first optical element between a retracted position and a desired position and to move the second optical element between the desired position and a retracted position substantially simultaneously such that a reaction torque of the first rotor cancels a reaction torque of the second rotor.Type: GrantFiled: September 3, 2014Date of Patent: September 26, 2017Assignee: Raytheon CompanyInventors: John P.

Patent number: 8919724Abstract: A mount for a mountable element includes a frame, and a plurality of flexures supported by the frame. The plurality of flexures are configured to be outwardly extended against a restorative bias, so that the element can be inserted therebetween. The mount further includes a plurality of intermediate bonds that may be inserted between the plurality of flexures and the element while the plurality of flexures are outwardly extended. Among other things, a system and method mounting the element are also disclosed.Type: GrantFiled: August 24, 2010Date of Patent: December 30, 2014Assignee: Raytheon CompanyInventors: Anjali Rangaswamy, Geoffrey A.

Publication number: 20130002066Abstract: A lightweight and efficient electrical machine element including a method of manufacture providing a stator winding for an electric machine which has a large portion of its volume containing electrically conductive strands and a small portion of its volume containing of an encapsulant material. The stator winding includes winding of a first phase (90) by shaping a portion of a bundle of conductive strands into an overlapping, multi-layer arrangement. Winding of successive phases (91, 92) occurs with further bundles of conductor strands around the preceding phases constructed into similar overlapping, multi-layer arrangements. The multiple p (90, 91, 92) are impregnated with the encapsulant material using dies (60, 80) to press the bundles into a desired form while expelling excess encapsulant prior to the curing of the encapsulant material. The encapsulated winding is removed from the dies after the encapsulant has cured. The encapsulant coating on the strands may be activated using either heat or solvent.Type: ApplicationFiled: February 28, 2011Publication date: January 3, 2013Applicant: LAUNCHPOINT TECHNOLOGIES, INC.Inventor: Geoffrey A.

Patent number: 8193883Abstract: A switching system includes two or more rotary switching mechanisms for selectively moving items. The switching system may be used for switching optical elements, such as filters, into and out of an optical path, for example selectively placing one of a group of available filters into the optical path. Each of the rotary switching mechanisms has a passive torque device, including a mechanical flexure and a magnetic latch, that provides most of the torque for moving an item between a retracted position and an extended position, and vice versa. The passive torque device has a pair of null positions or detents at the retracted and extended positions. A brushless DC motor is used to provide a force to get the passive torque device out of these null positions. Thereafter the passive torque device is able on its own to provide most of the torque for movement.Type: GrantFiled: October 30, 2007Date of Patent: June 5, 2012Assignee: Raytheon CompanyInventors: Geoffrey A. Long, Felix T. Sasso
