Patents by Inventor Christopher C Womack

Christopher C Womack has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7212409
    Abstract: A cooling system for a computer includes a cam-actuated cold plate. Compliant, thermally conductive pins on the cold plate contact electronic heat generating electronic components when the cold plate is moved toward a circuit assembly that includes the electronic components. Optionally, the cold plate may be cooled by circulating coolant through it.

  • Patent number: 6896611
    Abstract: A computer system uses a modular fan design. Multiple fan modules can be used, and identical fan modules can be used for directing air into and out of the computer system enclosure. Each fan module is hot swappable, and can be replaced quickly without the use of tools or fasteners. Optional mounting features on the fan and the computer enclosure prevent misassembly, and an optional color coding scheme aids in assembly. An optional splitting light pipe directs light from a single status-indicating source to both the front and back of the fan module.

  • Patent number: 6843664
    Abstract: A power connector is configured to float on a computer backplane allowing bulk power supplies to be physically located adjacent to the backplane. This allows use of an EMI gasket between the bulk power supply and the backplane preventing high frequency noise from radiating out of the computer case. Standard electrical plugs may be used on one or both sides of the power connector allowing standard bulk power supplies and line cords to be used on one or both sides of the power connector.

  • Patent number: 6829142
    Abstract: A variable gap thermal interface is coupled with a cold or hot plate, forming a low thermal resistance connection between an electronic device module containing at least one heat generating electronic device and a rack or other structure. The variable gap thermal interface and the cold or hot plate are provided in a configuration to allow quick-disconnect of the electronic device module from the rack, allowing for a wide dimensional tolerance between the module and the rack while maintaining a reliable thermal connection. An embodiment including a plurality of server modules within a server rack in conformance with the present invention, allows the replacement of server modules while powered without any disconnection or reconnection of hoses to cold plates used in cooling the server modules, thus greatly reducing the probability of leaks and resulting damage to the system.

  • Publication number: 20030075646
    Abstract: An inexpensive, flexible cable management device is constructed from a thin sheet of flexible material by cutting slits or openings in the material configured to efficiently and compactly route cables within an electrical system. Information such as assembly instructions and wiring diagrams may be printed on the device, and adhesive may be applied to the device to ease installation. The cable management device may be bent to allow three-dimensional routing of cables and to act as a barrier between air flows.
