The plurality of thermoelectric coolers is disposed between the first heat pipe and a thermal load, each of the plurality of thermoelectric coolers having a first surface and a second surface, each respective first surface having a first thermally conductive coupling to the first heat pipe and each respective second surface having a second thermally conductive coupling to the thermal load.

Abstract: A spacecraft includes substantially parallel first radiator and second radiator panels, and a transverse panel coupled, having a width, W, coupled therebetween. The spacecraft also includes a first heat pipe having a first section parallel and proximate to the first radiator panel and a second section parallel and proximate to the transverse panel, a second heat pipe having a first section parallel and proximate to the second radiator panel and a second section parallel and proximate to the transverse panel and a third heat pipe, proximate and parallel to the transverse panel, the second section of the first heat pipe, and the second section of the second heat pipe. The third heat pipe has a length, L, substantially greater than W/2.

Abstract: A system and method are provided for enabling telephone users to place information on a network that is accessible by a variety of devices from disparate communication protocols are provided. A telecommunications network provides access to one or more servers to one or more customers. A customer that is provided access to the server is enabled to create a basis of operations called a phonesite. The phonesite is constructed and arranged to allow read, write, and execute privileges to the customer and to those designated by the customer. Files and other information on the phonesite can be accessed and edited from, for example, a standard telephone, a personal computer, a personal digital assistant, a web cam, an instant message client, and the like. Customers are given a single number with which to access the phonesite, or to allow others to access the phonesite.

Abstract: An individual-centric Internet is provided with a personal base process on a computer system. The computer system is equipped with multiple nodes that are interconnected to facilitate the communication between the nodes. The personal base service includes a personal base instance that is typically in software on at least one of the nodes of the computer system, such as a network. The personal base instance is designed to communicate with a user by any digital or analog device, such as a telephone, personal computer, personal digital assistant, or the like. A personal base server is instantiated on at least one of the nodes on the computer system and is in operative communication with the personal base instance. The personal base server is used to communicate with other personal bases or other nodes on the computer system or network in order to insulate the user from other elements of the computer system.

Abstract: The present invention is to provide a test mechanism for testing a connection port of an electronic apparatus comprising a support platform on which at least one slideway is disposed, two mobile grasping components mounted respectively on these slideways such that these grasping components are able to push against both sides and one corresponding surface of the electronic apparatus and fix the electronic apparatus onto the support platform, for testing and estimating whether the connection port with a load object connected thereto in various angles meets with anticipated quality requirement.

Abstract: A chassis cover for a host unit of a computer system is disclosed. The chassis cover is preferably capable of covering a chassis which includes mountings for components which are movable in a direction. The chassis cover includes a first surface, and a movable side door having a closed position and an open position. The side door provides an opening in the chassis cover when in the open position to permit the mountings to be extended toward the opening when the side door is in the open position. By permitting the mountings to be extended toward an opening provided by the side door, the components within the host unit may be accessed and serviced without removing a heavy display monitor.

Abstract: A chassis cover of a host unit, which has a horizontal orientation and a vertical orientation, includes a side cover and a stabilizing stand. The side cover has outer peripheral edges and a cavity. The stand is movable between a closed position and an open position and is coupled to the side cover. The stand fits within the cavity in the side cover to form a substantially contiguous surface when the host unit is in the horizontal orientation and the stand is in the closed position. The stand projects beyond the outer peripheral edges of the side cover in a direction transverse to the depth of the host unit to stabilize the host unit in the vertical orientation resting on the side cover when the stand is in the open position.
