  • Publication number: 20240092036
    Abstract: A pipe fusion machine including a track mounted chassis supporting a horizontal turntable for unlimited, reversible rotation relative to the chassis. A boom pivotally attached at a rear end of, and extending forwardly of, the turntable enables manipulation of elevations and distances of the free end of the boom. The free end of the boom is adapted to permit pivotal mounting thereon of a pipe fusion tool such as an indexer configured to articulate and support a pipe-end facer and a pipe-end heater for respective independent orientation into and out of alignment with the ends of pipes to be fused. A carriage supports fixed and sliding jaws adapted to grip the ends of pipes to be fused for relative reciprocal movement during a pipe fusion process. Each of the jaws may include an upper half jaw and lower left and right quarter jaws.

  • Patent number: 9599717
    Abstract: An intelligent system for choosing selection schemes to be tried in a predetermined order for determining the location of a wireless mobile client, including retrieving a last known position record from a cache, checking serving network capability, choosing an initial selection scheme according to parameters including at least the required response time and the requested location method, including a method employing navigational satellites, attempting to retrieve a current position record, trying successive untried selection schemes in turn according to a predetermined algorithm if no current position record has been retrieved, and returning the current position record and updating the last known position record, or returning an error if no current position record has been retrieved, and returning the last known position record if an error has been returned, the last known position record exists in the cache and the last known position record has not expired.

  • Patent number: 6823255
    Abstract: A system and method for distributing information for storage media, and in particular, for distributing updated navigation data, such as geographical data and navigation application programs, contained on storage media and used in in-vehicle navigation systems. A plurality of local repositories are located in a geographical area. Each of the local repositories includes updated versions of navigation data for the navigation systems. Owners of vehicles having navigation systems may visit any of the repositories from time to time where they can obtain updated versions of the navigation data for their navigation systems. Subscriptions for obtaining updated navigation data would be available to the owners of navigation systems that would entitle them to obtain updated navigation data from the repositories. Procedures for updating the local repositories are also provided. The system and method can be used for updating other types of software.
