Patent number: 8977950Abstract: Techniques to select and manipulate table borders as discrete objects are described. In particular, a table border may be selected without having to select a cell that includes the desired border. In one embodiment, for example, a technique may include detecting a selector in proximity to a border in a table. The border in proximity to the selector may be highlighted visually on a display to show which part of the table border may be selected. A selection may cause the highlighted border to be selected. The now-selected border may then be manipulated. Other embodiments are described and claimed.Type: GrantFiled: October 4, 2011Date of Patent: March 10, 2015Assignee: Microsoft CorporationInventors: Caitlin Ashley-Rollman, Jessica Best, Levent Kartaltepe, Tristan Davis, Charles Walker, Susan Baker

Patent number: 8186731Abstract: Seals have a flexible wire that can be looped through a hasp-like device. The seals include a body having a recess, a plug insertable into the recess and a snap ring for fastening the plug to the body. The plug and/or body can have access holes for inserting the wire into the recess. “Teeth” on the outer diameter and through-holes through the thickness of the snap ring allow for passing the ends of the flexible wire from the recess through the snap ring. The ends of the wire can be folded back over the snap ring and into engagement with the teeth. Assembly of the seal causes the ends of the wire to be securely fastened between the teeth of the snap ring and the sidewall of the recess. Seals can include a plug and/or body made of a frangible material such as glass, ceramic, glass-ceramic or brittle polymer.Type: GrantFiled: April 14, 2009Date of Patent: May 29, 2012Assignee: Sandia CorporationInventors: Juan A.

Patent number: 7938707Abstract: Methods are disclosed for batch fabrication of vacuum switch tubes that reduce manufacturing costs and improve tube to tube uniformity. The disclosed methods comprise creating a stacked assembly of layers containing a plurality of adjacently spaced switch tube sub-assemblies aligned and registered through common layers. The layers include trigger electrode layer, cathode layer including a metallic support/contact with graphite cathode inserts, trigger probe sub-assembly layer, ceramic (e.g. tube body) insulator layer, and metallic anode sub-assembly layer. Braze alloy layers are incorporated into the stacked assembly of layers, and can include active metal braze alloys or direct braze alloys, to eliminate costs associated with traditional metallization of the ceramic insulator layers. The entire stacked assembly is then heated to braze/join/bond the stack-up into a cohesive body, after which individual switch tubes are singulated by methods such as sawing.Type: GrantFiled: July 7, 2008Date of Patent: May 10, 2011Assignee: Sandia CorporationInventors: Charles A.
