Abstract: A document collaboration process is centered around a digital media object that is the subject of the collaboration, and makes the role of the server computer that is hosting the collaboration session more transparent to the user. As a result, a user can initiate a collaboration session without logging into the server computer and uploading the digital media object into the server computer. A user can also join a collaboration session without logging into the server computer. The process for initiating a collaboration session may be performed directly from the browser while viewing a web page, directly from an e-mail interface while viewing an e-mail, directly from an Instant Messaging Interface while participating in an IM session or directly from a file browser while viewing a list of files stored in the user computer.

Abstract: A method for privacy management includes providing a linked collection of interactive resources through which a user is able to exchange information with an enterprise that provides the resources, and assigning respective, non-uniform privacy policies to at least some of the resources regarding use of the information that is exchanged through the resources. The user, accessing a given one of the resources, is provided with the respective privacy policy for that resource. At least a portion of the information that is associated with the given one of the resources is exchanged with the user subject to the provided privacy policy.

Abstract: The invention is a spaced based navigation system for guiding a spacecraft. In detail, the navigation system includes at least two Doppler range/range rate satellites positioned at LaGrangian stability points between first and second planetary bodies wherein the first planetary body rotates about the second planetary body. A processing system mounted on the spacecraft for receiving Doppler range and range rate data from said at least two Doppler range/range rate satellites and calculating the position and velocity of the spacecraft.

Abstract: A lamp includes an enclosure with partitions defining a channel having channel segments and/or providing multiple paths for an electrical arc to travel. The channel segments can be implemented by adding additional electrodes in the channel formed by the partitions, by forming a channel where the arc may travel in multiple directions, or by a combination of these methods. The channel segments and multiple directions of arc travel tend to reduce the voltage required to start the lamp.

Abstract: An apparatus and method is disclosed for regulating the cold spot temperature of a light emitting enclosure. A cold spot regulation system defines and controls the temperature of the cold spot. The cold spot regulation system includes an interface housing secured to the light emitting enclosure and two ducts extending from the interface housing. The cold spot regulation system uses a coolant fluid to lower the operating temperature of the light emitting enclosure. The coolant fluid is diverted into one of the ducts. The coolant fluid is passed by the cold spot of the light emitting enclosure and released out the other duct.

Abstract: A light source incorporates light emitting diodes (LEDs). The LEDs may be raised off the floor of the optical cavity to permit light to be emitted from the base of the LED. Additionally, a reflective protrusion may be placed beneath the raised LED to aid in redirecting light forward. The LEDs may be skewed in relation to adjacent LEDs to reduce interference. Non-white LEDs may be incorporated into the light source to permit for selective color tuning. Fluorescent lamps may also be implemented in combination with the LEDs to form a hybrid light source.

Abstract: A method and apparatus for extending the main memory of computer systems across network boundaries is provided. A memory server is allocated on a network server, or a separate machine connected to a network to enable client computers on the network to extend their main memory on demand for user applications. Through the utilization of the memory server, the client workstations can execute programs requiring more memory than is resident on the client without decreasing the efficiency of the network server.

Abstract: A light source incorporates phosphor-based white light emitting diodes (LEDs). The LEDs may be raised off the floor of the optical cavity to permit light to be emitted from the base of the LED. Additionally, a reflective protrusion may be placed beneath the raised LED to aid in redirecting light forward. The LEDs may be skewed in relation to adjacent LEDs to reduce interference. Non-white LEDs may be incorporated into the light source to permit for selective color tuning. Fluorescent lamps may also be implemented in combination with the LEDs to form a hybrid light source. The light source may be used as a backlight for a liquid crystal display assembly.
