  • Publication number: 20120006151
    Abstract: An auxiliary power unit includes a gearbox housing portion and a filter housing portion providing an integral housing. A filter cavity is provided in the filter housing portion. A surface circumscribes the filter cavity. A scupper includes a passage extending from the surface to an opening on an exterior surface of the integral housing. A sealing region between the scupper and the filter cavity is configured to fluidly isolate the scupper and the fuel filter cavity from one another. In one example, the filter cavity receives a fuel filter cartridge. A cap is secured to the filter housing portion and encloses the filter cavity when in a secured position.

  • Publication number: 20100175300
    Abstract: An interactive, mobile decoy system uses a bent wire framed assembly with two parallel support runners which transition rearward in an 180 degree arc toward the center of gravity of the support runners and terminate at a junction block. The block joins a support mechanism with a decoy attaching point. A pull mechanism incorporates a pivoting decoy mounting point for causing a decoy mounted thereon to realistically simulate the feeding motions of game fowl in general and wild turkeys in particular, especially a strutting motion of a male and a feeding behavior of a hen.

  • Publication number: 20070263668
    Abstract: In one embodiment, an audio record is received over a communication link and buffered. A data window is aligned with a portion of a buffer that contains the buffered audio record; and a portion of the buffered audio record to which the data window is aligned is compared with a portion of a reference audio record. If the portions of the buffered and reference audio records match, the records are synchronized in accord with a current position of the data window; and an audio quality of the buffered audio record is evaluated by comparing the synchronized audio records. If the portions of the buffered and reference audio records do not match, a location of the data window is incremented with respect to the buffer; and a comparison of A) the portion of the buffered audio record to which the data window is aligned, to B) the portion of the reference audio record, is repeated.

  • Publication number: 20070037756
    Abstract: The present invention relates to compositions and the prevention and treatment of circulatory conditions. In one embodiment, the present invention contemplates a compositions comprising anti-platelet aggregating activity. In another embodiment, the present invention contemplates methods to prevent or treat vascular or cardiovascular diseases. In another embodiment, the present invention relates to a method to prevent or treat cardiovascular disease by administering a glycerol saccharide derivative, an arylpolyphenol, a saccharide substituted with an arylpolyphenol, or a steroid substituted with an arylpolyphenol capable of reducing platelet aggregation. In one embodiment, the invention relates to a method of using the compounds capable of reducing platelet aggregation in order to prevent the recurrence of a heart attack by administration of the compounds to a subject after the subject has experienced a heart attack.

  • Patent number: 7176421
    Abstract: A heater for heating a rigid fluid line or hose for freeze protection. The heater has a base made of an outer base layer, a middle base layer attached to the outer base layer; and an inner base layer attached to the middle base layer. The inner base layer can be uncured silicone (before assembly processing). A resistance wire is wound around an electrically non-conductive core and located on the inner base layer. The resistance wire can be a high gauge wire providing for a small moment of flexure. A cover includes an inner cover layer covering said resistance wire. This inner cover layer can be uncured silicone (before assembly processing). A middle cover layer is attached to the inner cover layer, and an outer cover layer is attached to the inner cover layer. The outer cover layer protects the heater from abrasion.

  • Patent number: 7176920
    Abstract: A computer games apparatus includes a server operable under the control of a computer program to generate and store data defining a 3D game environment. Objects within that environment can be moved and/or changed in response to signals received by the server from player terminals. Those signals may be transmitted via the Internet and/or other networks. The server renders the object data into data defining one or more views of the 3D environment, which data can then be processed into a broadcastable form for receipt by a plurality of observers. The performance of the apparatus is unaffected by the number of observers actually in receipt of the broadcast data.

  • Publication number: 20060245364
    Abstract: A continuous bi-directional file-play-record voice and video quality tester system (“CFPR-VVQT”) for measuring the quality of voice or video communication links from a customer premises equipment (“CPE”) through a Network under Test to a voice and video quality tester (“VVQT”). The start and end of a set of quality testing sample signals are determined by a start flag signal and an end flag signal, respectively, generated by the CFPR-VVQT. The flag signals may be triple tone modulation frequency (“TTMF”) tones. The CFPR-VVQT will measure the quality testing sample signals, determine a signal quality test result, and then transmit the test results back through Network under Test to the originating VVQT.

  • Publication number: 20050252142
    Abstract: An anchorage system for structural reinforcement of surface bonded reinforcing sheet, plate or shell made of fiber reinforced plastic (FRP) or steel or other metallic or non-metallic materials is disclosed. The anchorage system comprises an anchor tube or solid rod with a circular outer surface and a lock-down means provided along the longitudinal axis of the tube or rod. The lock-down means can be either an anchor bolt mounted through the center of the anchor tube or rod or an anchor strap pressed against the circular surface of the tube or rod into the members to be reinforced. The FRP reinforcing sheet, plate or shell is bonded to the surface of the structural member, and optionally, the supporting member, and passes underneath the outer circular surface of the tube or rod. The tube or rod is held securely by the lock-down means which, in turn, compresses and holds in place the FRP sheet against the surface of the structural member.

  • Patent number: 6850766
    Abstract: A voice activated wireless locator service provides an interactive voice response system whereby a user is walked through a sequence of voice prompts to select a desired destination. Using either geo-coded information provided during the voice call or speech recognition of a shortcut phrase associated in a database with a street address, and using a locator service database, the system can provide spoken instructions using a text to speech engine, providing the name, location, and driving directions to one or more destinations matching the criteria provided by the user. Because the system uses speech recognition technology, it is particularly well suited for wireless access devices, such as cellular telephones, which are often used when a user is engaged in other activities, such as driving.
