High Temperature Environment Capable Motor Controller
US Patent:
2013009, Apr 18, 2013
Filed:
Oct 18, 2011
Appl. No.:
13/275914
Inventors:
Jay W. Kokas - East Granby CT, US
Richard E. Versailles - New Hartford CT, US
Robert D. Klapatch - Wethersfield CT, US

Assignee:
HAMILTON SUNDSTRAND CORPORATION - Windsor Locks CT
International Classification:
H02K 9/00
US Classification:
310 52
Abstract:
A motor controller for use in an environment at a high maximum environmental temperature comprises an insulated chassis, a high-temperature capable electronic component, a low-temperature capable electronic component, and a heat pump. The high-temperature capable electronic component is rated for temperatures higher than the environmental temperature, whereas the low-temperature capable electronic component is rated for temperatures lower than the maximum environmental temperature. The insulated chassis has a finned surface to which the high-temperature capable electronic component is mounted. The low-temperature capable electronic component is attached to or integrated into a printed wiring board supported inside the insulated chassis by the thermally conductive posts. The heat pump is configured to draw heat from the low-temperature capable electronic component through the thermally conductive posts and a thermal spreader abutting the heat pump, and to expel heat into the finned surface of the insulating chassis.
Vertically Mounted Multi-Hybrid Module And Heat Sink
US Patent:

Assignee:
Hamilton Sundstrand Corporation - Windsor Locks CT
International Classification:
H05K 7/20
US Classification:
361715, 36167954, 361708, 361721, 361704, 165 803, 16510433, 165185
Abstract:
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.
Removable Circuit Card Insert Extractor
US Patent:
2013030, Nov 14, 2013
Filed:
May 14, 2012
Appl. No.:
13/470904
Inventors:
Kenneth J. Trotman - Granby CT, US
Michael Maynard - Springfield MA, US

Assignee:
HAMILTON SUNDSTRAND CORPORATION - Windsor Locks CT
International Classification:
G06F 1/16, B23P 19/00
US Classification:
36167958, 29762
Abstract:
A removable tool includes a toe, a clevis, and a handle. The toe is configured to be insertable into and removable from an enclosure notch of a card guided computer enclosure. The clevis is configured to be insertable into and removable from a card hook of a circuit card assembly. The handle is for receiving force for inserting or extracting an array of circuit card assembly contacts into or out of an array of motherboard contacts, respectively.
