Patent number: 8463448Abstract: An energy consuming device comprises a power consuming feature/function and a controller operatively connected to the power consuming feature/function. The controller is configured to operate the device including the power consuming feature/function in one of a plurality of operating modes, including at least a normal operating mode during an associated off-peak demand period of an associated energy supplying utility and an energy savings mode during an associated peak demand period of the associated energy supplying utility. The controller is configured to provide a user a grace period during the associated peak demand period to allow the user to change the operating mode of the power consuming feature/function from the energy savings mode to another operating mode including the normal operating mode thereby allowing additional use of the power consuming feature/function during the associated peak demand period.Type: GrantFiled: December 22, 2009Date of Patent: June 11, 2013Assignee: General Electric CompanyInventors: Ashley Wayne Burt, Michael F. Finch, Gregory F. Gawron, Mark Davis Johnson, Jeffrey S. Weber

Patent number: 7981258Abstract: A thin film device, such as an intravascular stent, is disclosed. The device is formed of a seamless expanse of thin-film (i) formed of a sputtered nitinol shape memory alloy, defining, in an austenitic state, an open, interior volume, having a thickness between 0 5-50 microns, having an austenite finish temperature Af below 37° C.; and demonstrating a stress/strain recovery greater than 3% at 37° C. The expanse can be deformed into a substantially compacted configuration in a martensitic state, and assumes, in its austenitic state, a shape defining such open, interior volume. Also disclosed is a sputtering method for forming the device.Type: GrantFiled: January 21, 2009Date of Patent: July 19, 2011Assignees: Stryker Corporation, Stryker NV Operations Limited, Tini Alloy CompanyInventors: A.

Patent number: 4055955Abstract: A heat engine and method of operation employing an alloy having a shape memory effect. A memory alloy element such as one or more wire loops are cyclically moved through a heat source, along a path toward a heat sink, through the heat sink and then along another path in counter-flow heat exchange relationship with the wire in the first path. The portion of the wire along the first path is caused to elongate to its trained length under minimum tension as it is cooled. The portion of the wire along the second path is caused to contract under maximum tension as it is heated. The resultant tension differential between the wires in the two paths is applied as a force through a distance to produce mechanical work. In one embodiment a first set of endless memory alloy wires are reeved in non-slip engagement between a pair of pulleys which are mounted for conjoint rotation within respective hot and cold reservoirs.Type: GrantFiled: August 16, 1976Date of Patent: November 1, 1977Inventor: Alfred Davis Johnson
