Patent number: 7880837Abstract: A cholesteric display may be formed, in some embodiments, using a single display element to produce multi-colors for display. A cholesteric material may be sandwiched between a pair of substrates, each associated with pairs of opposed electrodes that are arranged in general transversely to the optical axis of incident light. The first pair of electrodes produce one of two liquid crystal states and result in the reflection of light of a particular wavelength. Light of other wavelengths may be reflected when a second pair (or set) of opposed electrodes, arranged in general transversely, also to the optical axis of incident light, are biased appropriately. So does a third pair (or set) of electrodes. A black and white color display may be generated from a single display element by modulating the pitch length of the cholesteric material within each pairs (or sets).Type: GrantFiled: September 28, 2009Date of Patent: February 1, 2011Assignee: Intel CorporationInventors: David B. Chung, Daniel J. Lenehan

Patent number: 7591302Abstract: A method of and apparatus for cooling heat-generating devices in a cooling system is disclosed. The apparatus includes various sensors, control schemes and thermal models, to control pump flow rates and fan flow rates to minimize power consumption, fan noise, and noise transients. The apparatus further includes at least one heat-generating device, at least one heat exchanger, and at least one heat rejector. The apparatus can also include many pumps and fans. The method includes controlling a fluid flow rate of at least one pump and an air flow rate of at least one fan, in a cooling system for cooling at least one device. The method comprises the steps of: providing at least one temperature sensor coupled to measure a temperature value of each device; receiving the temperature value from each temperature sensor; and providing a controller to selectively control the fluid flow rate and the air flow rate, based on each temperature value.Type: GrantFiled: December 8, 2003Date of Patent: September 22, 2009Assignee: Cooligy Inc.Inventors: Daniel J.

Patent number: 7086839Abstract: An electroosmotic pump and method of manufacturing thereof. The pump having a porous structure adapted to pump fluid therethrough, the porous structure comprising a first side and a second side, the porous structure having a plurality of fluid channels therethrough, the first side having a first continuous layer of electrically conductive porous material deposited thereon and the second side having a second continuous layer of electrically conductive porous material deposited thereon, the first second layers coupled to a power source, wherein the power source supplies a voltage differential between the first layer and the second layer to drive fluid through the porous structure at a desired flow rate. The continuous layer of electrically conductive porous material is preferably a thin film electrode, although a multi-layered electrode, screen mesh electrode and beaded electrode are alternatively contemplated.Type: GrantFiled: September 23, 2003Date of Patent: August 8, 2006Assignee: Cooligy, Inc.Inventors: Thomas W.

Patent number: 7007304Abstract: An improvement to a graphics controller to prevent the contents of selected portions of the frame buffer from being read by devices external to the graphics controller. The invention defines one or more viewable rectangles in the frame buffer as a protected write-only area. Any attempt to read data from the protected area of the frame buffer triggers a security violation which can delete or destroy the contents of that area to prevent it from being read. The controller can also operate in a bypass mode in which the security functions are bypassed so the graphics controller operates in a conventional manner. A security violation may return the controller to the bypass mode. The invention can prevent protected data, such as copyrighted data downloaded over the Internet, from being copied from the frame buffer and used in an unauthorized manner.Type: GrantFiled: September 20, 2000Date of Patent: February 28, 2006Assignee: Intel CorporationInventors: Luke E. Girard, Steven G. Preston, Daniel J. Lenehan
