Patent number: 9560774Abstract: A high-speed router backplane is disclosed. The router backplane uses differential signal pairs on multiple signal layers, each sandwiched between a pair of digital ground layers. Thru-holes are used to connect the differential signal pairs to external components. To reduce routing complexity, at least some of the differential signal pairs route through a via pair, somewhere along their path, to a different signal layer. At least some of the thru-holes and vias are drilled to reduce an electrically conductive stub length portion of the hole. The drilled portion of a hole includes a transition from a first profile to a second profile to reduce radio frequency reflections from the end of the drilled hole.Type: GrantFiled: March 14, 2012Date of Patent: January 31, 2017Assignee: Force10 Networks, Inc.Inventors: Joel R. Goergen, Greg Hunt

Patent number: 9003652Abstract: The characteristic impedance of a surface pad is manipulated by reticulating the pad and filling the spaces with a dielectric material, providing an inductive element in the coupling of the surface pad to an underlying ground pad of a ground plane, or a combination of these approaches. In appropriate embodiments, acceptable signal trace routing paths will exist in an embedded signal layer under the ground plane and crossing under the surface pad. Other embodiments are also described and claimed.Type: GrantFiled: February 20, 2012Date of Patent: April 14, 2015Assignee: Dell Products L.P.Inventors: Joel R. Goergen, Greg Hunt, Peter Tomaszewski, Joseph Pankow, Michael Laudon

Patent number: 8747383Abstract: A method and system for wrinkle reduction. The method includes the steps of positioning and applying a patch to skin of a consumer and adhesively securing the patch to the skin. A chemical composition on the patch includes both active ingredients and adhesive. A pair of electrodes are connected to a battery-driven, microprocessor-based controller. A current is applied through the electrodes in the patch for a selected time. The chemical composition in the patch is propelled into the consumer through use of the current in order to relax the skin of the consumer. The patch is removed and any residue of the chemical composition is massaged into the skin.Type: GrantFiled: December 16, 2010Date of Patent: June 10, 2014Assignee: University Medical Pharmaceuticals Corp.Inventors: Ray Francis, John Trengove, Greg Hunt, Josh Hoyt, Jim Thorne, Darrick Carter

Patent number: 7897880Abstract: Plated through holes pass through clearances in a ground plane of a circuit board. A conductive collar/spoke arrangement is constructed on the ground plane adjacent the clearance, to provide an inductive component to the coupling between a plated through hole and the ground plane. The inductive component impedes the transfer of high-frequency noise between the through hole and the ground plane. Other embodiments are also described and claimed.Type: GrantFiled: December 7, 2007Date of Patent: March 1, 2011Assignee: Force 10 Networks, IncInventors: Joel R.

Patent number: 7088711Abstract: A high-speed router backplane is disclosed. The disclosed construction and layout techniques enable the construction of a reliable, high-layer-count, and economical backplane for routers and the like that use signaling across the backplane at trace speeds of 2.5 Gbps or greater. Specific ranges of differential trace geometry characteristics, with significant single-ended coupling to adjacent ground planes, have been found to provide the parameters needed for such signaling. New trace routing and layering techniques also help in the realization of a backplane embodiment containing roughly 600 operable high-speed differential pairs, while also providing sufficient electromagnetic interference management to allow power distribution to occur within the same backplane.Type: GrantFiled: February 5, 2002Date of Patent: August 8, 2006Assignee: Forcelo Networks, Inc.Inventors: Joel R.
