  • Patent number: 7903413
    Abstract: A system and method are provided including a first thermal component adapted for thermal communication with an integrated circuit, and a second thermal component adapted for thermal communication with the first thermal component upon engagement therewith. Further provided is a coupler slidably coupled to the first thermal component and/or the second thermal component. In use, such coupler is capable of a first orientation for disengaging, the first thermal component and the second thermal component, and a second orientation for engaging the first thermal component and the second thermal component.

  • Patent number: 7626821
    Abstract: Embodiments of this invention relate generally to systems used to cool computer hardware and more particularly to an adaptor for a graphics module. In one embodiment a graphics card assembly is provided. The graphics card assembly includes a printed circuit board (PCB); a graphics processing unit (GPU) attached to the PCB; and an adaptor having first and second surfaces and made from a thermally conductive material. The adaptor is disposed on the PCB so that the first surface is in thermal communication with the GPU and the second surface providing a standard interface for thermal communication with a cooling system.

  • Patent number: 7621769
    Abstract: One embodiment of an edge connector for a field changeable graphics system includes a right angle edge connector having a plurality of contact pins adapted to engage contacts on a graphics card. The edge connector is adapted to interface the graphics card with the motherboard of a computing device, without directly mounting the graphics card to the motherboard. One advantage of the disclosed edge connector is that it is compatible with a plurality of graphics cards and systems, thereby enabling a computing device user to upgrade the existing device's graphics system. Thus, the user is not forced to purchase an entirely new computing device in order to take advantage of graphics innovations. A further advantage of the disclosed edge connector is that it enables upgrades to low voltage differential signaling (LVDS) features, without the need for additional costly devices capable of operating at LVDS data rates.

One advantage of the disclosed graphics system is that it enables a computing device user to upgrade the existing device's graphics system. Thus, the user is not forced to purchase an entirely new computing device in order to take advantage of graphics innovations. This advantage is particularly significant for users of portable computing devices, such as laptop computers and PDAs.
