Patent number: 8798856Abstract: An accessory load control system for a vehicle, includes an actuator control module, a period estimation module, and a load control module. The actuator control module operates an internal combustion engine of the vehicle in a high-efficiency (HE) mode. The period estimation module estimates a period between a current time and a future time when an actual load on a crankshaft of the engine will reach a maximum engine load associated with the HE mode. The load control module selectively decreases engine loads applied by vehicle accessories, respectively, based on the period.Type: GrantFiled: April 12, 2010Date of Patent: August 5, 2014Inventors: Gregory A.

Patent number: 8136874Abstract: A fluid-based or fluidic climate control system for a seat includes first and second portions positionable adjacent to first and second surfaces of the seat and a fluid control module (FCM) for circulating fluid in a closed-loop within the portions. The FCM delivers fluid to the portions at independently-controllable temperatures. An interface may be used to control the temperatures. The FCM may include a heat exchanger module (HEM) having a fan connected to an energy storage device (ESD). The FCM may include a miniature vapor compressor for circulating the fluid. A method of cooling a seat includes positioning first and second portions of the system adjacent to different surfaces of the seat, and using the FCM to circulate fluid within a closed-loop passage of the portions while independently controlling the temperature of the fluid, and thus the portions, using a user interface.Type: GrantFiled: May 29, 2009Date of Patent: March 20, 2012Assignee: GM Global Technology Operations LLCInventors: Milton Jose Negrini, Gregory A.

Patent number: 7078802Abstract: A method and resulting electronic package in which a heat sink is secured to the package's dielectric material (e.g., overmold). The surface of the dielectric is roughened (e.g., using an abrasive paper or pad) to enhance the subsequent dielectric-heat sink bond in which an adhesive is used. The dielectric material's roughened external surface(s), typically containing silicone material (e.g., silicone residue) which is an inherent by-product of many dielectric materials of the type used in such packaging, is (are) able to still be securely attached to the heat sink, despite the presence of said silicone. In another embodiment, the roughened surface enhances the marking of dielectric material of this type (e.g., using ink).Type: GrantFiled: November 8, 2004Date of Patent: July 18, 2006Assignee: International Business Machines CorporationInventors: Michael Gaynes, William R.

Patent number: 5308438Abstract: An apparatus and method for determining a selected endpoint in the polishing of layers on a workpiece in a chemical/mechanical polishing apparatus where the workpiece is rotated by a motor against a polishing pad. When a difficult to polish layer, i.e., one requiring a chemical change in a surface skin of the layer which skin is then abraded away by a mechanical process is removed from a more easy to polish surface, i.e., one that relies solely on mechanical abrasion and does not need to have a chemically converted skin thereon. The power required to maintain a set rotational speed in a motor rotating the workpiece significantly drops when the difficult to polish layer is removed. This current drop is used to detect the point at which the polishing must be stopped to avoid over polishing effects, i.e., dishing or thinning or removal of the more easily removed underlying material. Thus, an end point in the process can be established.Type: GrantFiled: January 30, 1992Date of Patent: May 3, 1994Assignee: International Business Machines CorporationInventors: William J.
