Patent number: 8638535Abstract: A system comprises a package with top and bottom surfaces, a plurality of high-power transient voltage suppressors arranged within the package, and a robust lead frame. Each of the transient voltage suppressors has first and second major surfaces substantially perpendicular to the top and bottom surfaces of the package. The lead frame comprises leads connected to the major surfaces of the transient voltage suppressors. Each of the leads has a thickness greater than about 0.015 inches (or 0.381 mm) in a mounting portion, in order to dissipate heat from the transient voltage suppressors and to resist vibration-induced stress on the package.Type: GrantFiled: January 10, 2011Date of Patent: January 28, 2014Assignee: Hamilton Sundstrand CorporationInventors: Kevin P. Roy, Richard A. Poisson, Jay W. Kokas, Edward John Marotta, Robert C. Hoeckele, Luke T. Orsini, Marc S. McCloud, Matthew S. Fitzpatrick

Patent number: 8542490Abstract: A multi-hybrid module includes a plurality of hybrid assemblies that are perpendicularly mounted with respect to a plane of a circuit board. The hybrid assemblies are mounted on opposing sides of a heat sink. The heat sink has a first column disposed at a first end, a second column disposed at a second opposing end, and a generally flat center wall extending between the first column and the second column to which the hybrid assemblies are mounted. During operation the hybrid assemblies are mounted on edge perpendicular with respect to the circuit board to minimize an area profile of the multi-hybrid module on the circuit board.Type: GrantFiled: June 16, 2011Date of Patent: September 24, 2013Assignee: Hamilton Sundstrand CorporationInventors: Jay W. Kokas, Kevin P. Roy, Judy Schwartz, Michael Maynard, John D. Pennell, Matthew S. Fitzpatrick, Richard M. Speziale

Patent number: 8340793Abstract: An electronic control configuration includes at least one secondary microprocessor operable to control a device. The at least one secondary microprocessor assumes protection control of the device responsive to a first type of failure by transmitting a protection control signal to a first effector. The at least one secondary microprocessor assumes backup control of the device responsive to a second type of failure by transmitting a backup control signal to a second effector. The backup control functionality of the at least one secondary microprocessor can be selectively disabled.Type: GrantFiled: June 1, 2010Date of Patent: December 25, 2012Assignee: Hamilton Sundstrand CorporationInventors: Jeffry K. Kamenetz, Gregory DiVincenzo, Mark A. Johnston, Jay W. Kokas, Luke T. Orsini, Steven R. Fischer, Jay H. Hartman, Kevin P. Roy, William Betterini

Patent number: 8237416Abstract: A generator and associated power supply system has a prime mover for driving a shaft to rotate. A pair of permanent magnets is associated with the rotating shaft. A first stator winding is associated with a first of said permanent magnets, with a customer DC bus for providing a first relatively low voltage to the customer DC bus. A second of said permanent magnets is associated with a second stator winding, and an engine accessory DC bus. The engine accessory DC bus provides power to a motor controller and associated accessory motors associated with the prime mover. The engine accessory DC bus is provided with a second relatively high voltage from the second stator winding.Type: GrantFiled: December 9, 2008Date of Patent: August 7, 2012Assignee: Hamilton Sundstrand CorporationInventors: Gregory I.
