  • Patent number: 8977950
    Abstract: 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.

  • Patent number: 8895138
    Abstract: An impact resistant composite article has two or more layers of ballistic fabric and ionomer layers disposed between the fabric layers. The ionomer is highly neutralized so that it has essentially no melt flow. A process also for making such a composite article that involves deposition of an aqueous colloid of the ionomer onto the fabric, followed by drying.

  • Publication number: 20130056010
    Abstract: A self-contained Autonomous Positive Air Pressure (APAP) device that treats sleep apnea by providing pressurized air intermittently or on demand. The self-contained device is inconspicuously designed as eyewear and does not require the user to be tethered to an air hose or power cord. The device also does not require the user to wear a face mask sealed to the user's face. Instead, the present invention comprises a system that is battery powered including pumps to pressurize a chamber or chambers that provides breathable air through electronically controlled pressure regulated valves that prevents upper airway obstruction.

  • Patent number: 8186731
    Abstract: 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.

  • Publication number: 20120000934
    Abstract: In a dispensing appliance for dispensing a beverage from a powdered beverage container, a cartridge includes a container containing powdered beverage, and a dispenser on the container operable to dispense powdered beverage from the container. The appliance includes a mount for removably supporting the cartridge on the dispensing appliance, and a drive system configured for operative connection with the dispenser upon loading of the cartridge into the mount. The drive system is operable to operate the dispenser to release powdered beverage from the container. The beverage may be dispensed from the appliance in its powder form, or mixed with a liquid and dispensed generally in a liquid form. In a method of refilling a dispensing appliance, an empty cartridge of powdered beverage is replaced with a new, substantially full cartridge of powdered beverage with the cartridge dispenser operatively connected to the drive system of the appliance.

  • Patent number: 7938707
    Abstract: 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.

  • Patent number: 7933164
    Abstract: A technique includes performing at least one intervening towed seismic survey after a prior towed seismic survey and before a future towed seismic survey. The prior towed seismic survey has associated first streamer positions, and the future towed seismic survey has associated second streamer positions that do not coincide with the first streamer positions. The technique includes using measurements that are acquired in the intervening towed seismic survey(s) to link the prior towed seismic survey to the future towed seismic survey for time lapse analysis involving the prior and future towed seismic surveys.
