  • Patent number: 8386334
    Abstract: A system and methods for mapping price and location of tickets in an event venue are described. An interactive event venue seat map is provided by a network-based system that implements an online marketplace for tickets for upcoming events. The interactive event venue seat map enables sellers to view pricing information and transaction information for both sold and current event listings for any section or zone in an event venue. The interactive event venue seat map allows sellers to browse and click on sections to see sold and listed data for any section and zone in the event venue and to compare a proposed sale price to available pricing information of sold and current event listings in comparable sections. Other embodiments are described and claimed.

  • Patent number: 8381445
    Abstract: A sliding door system 11 can include a sealing mechanism 40 such that, when a door panel 10, 10a is slid to a closed configuration 100, one ore more seal elements 42 are extended to form a seal between the door panel 10, 10a and it surroundings at the bottom, top and/or sides of the door to reduce or prevent infiltration of gases or liquids such as air or water. Manual or motor driven movement of the door panel 10, 10a can automatically move an actuation mechanism 50, 50a to extend the seals around the door. The sealing member 40 can include weather stripping, brush or another seal element 42 that is extended into sealing contact with a floor 6 or other surface. Multiple door panels 10, 10a including the sealing system can be arranged to form a door panel system 11.

  • Publication number: 20120291359
    Abstract: A recessable rotary sliding door handle system provides for comfortable movement of a door or fenestration product with enough durability and strength for everyday use on a large door product. The handle system can include one or two recessable handles with comfortable grips, with balanced weighting to allow the handles to maintain an exposed usable configuration position when swiveled about its axis. In an exposed configuration, the handle is open and accessible for opening and closing a door. In a recessed configuration, the handle is closed to provide a clean appearance and allow the fenestration product to completely pocket within a walled enclosure.

  • Publication number: 20090144187
    Abstract: Systems, methods, and computer program product for generating a report or document including a data representation reflecting a distribution of hidden trade order volume across different locations and a relative size, including average hidden order volume, volume executed against hidden orders, as a percentage of total trading volume by exchange, liquidity group and time bins. Order execution data is received for a plurality of executed trades via an electronic quotation feed associated with an electronic trading forum for trading both displayed orders and non-displayed orders. For a plurality of time periods, the location within the best bid, best offer spread, of each executed trade of the plurality of executed trades, is determined by comparing the price of each executed trade for hidden orders to quotes on a limit book for the electronic trading forum at a point in time substantially immediately before the corresponding executed trade.

  • Patent number: 7245735
    Abstract: An earmuff structure for headset or ear protector includes two earmuff shells and two integrally injection molded speaker mounting plates that are screwed to an inner side of the earmuff shells and each has a central hole for receiving a speaker therein. The speaker mounting plates are provided at a rear surface with wall portions of predetermined heights. The wall portions on one of the speaker mounting plates are formed from outer bottom surfaces of two battery compartments formed on a front surface of the speaker mounting plate at two sides of the central hole. With the speaker mounting plates, batteries and speakers may be quickly assembled to form the earmuffs or disassembled for replacement. The wall portions on each speaker mounting plate cooperates with a foam located behind the speaker to define a space functioning like a cabinet, creating clear and high quality stereo sounds output from the speakers.

  • Patent number: 6961436
    Abstract: A noise-protecting arrangement for ear protector includes an audio-frequency receiving unit, a first audio-frequency amplifying unit, a volume control amplifying unit, a current amplifying unit, a gain control signal unit, an impedance matching unit, a gain control unit, a gain adjusting unit, a volume regulating unit, a second audio-frequency amplifying unit, and an audio-frequency output unit. The noise-protecting arrangement automatically attenuates a noise that enters into the ear protector and is higher than a predetermined dB level, and thereby protects a user's eardrum. The ear protector with this noise-protecting arrangement is suitable for use in environments in which various machine tools, such as drills, millers, lathes and the like are operated, firing training is performed, high-pressure air horn, vehicles, and aircrafts are maintained, or other types of high-frequency noises exist.
