  • Publication number: 20140149027
    Abstract: Systems and method including receiving at a server, commute information, said commute information including at least a start location and a destination location and a drive time. Requesting current transit time for the commute information from a remote server, said remote server operable to provide substantially real-time commute information. Receiving at said server the current transit time and comparing the current transit time the drive time, and sending a notification in response to said comparing. Some embodiments may include determining if the current transit time is at or below the drive time and sending messages by email, text message or a web-site posting.

  • Patent number: 6850066
    Abstract: A gradient compensation system comprising a magnet assembly, at least one field-generating gradient coil operable for generating magnetic field gradients in three orthogonal coordinates, and at least one gradient compensation coil positioned adjacent to the magnet assembly and operable for generating a magnetic field to compensate for leakage fields. A system for eliminating image distortion in magnetic resonance imaging comprising a magnet assembly comprising an imaging gradient coil and an imaging volume, and at least one gradient compensation coil positioned adjacent to the magnet assembly operable for generating gradient compensation fields in response to the magnetic field change.

  • Patent number: 6114227
    Abstract: This invention relates to the design of apparatus for processing electronic devices, including equipment for chemical vapor deposition or transport polymerization. The new designs of gas separator plates, their configuration, and the regulation of gas flows through the system provides control over the pattern of precursor gas flow away from the separation plates, thereby decreasing the amount of byproducts that are deposited on the plates and throughout the reactor. New designs for shaping other surfaces of the dispersion head reduces contamination of those elements, and new designs for chamber panels decrease the deposition of byproducts on those surfaces, as well as other elements of the reactor. Decreasing deposition of byproducts increases the amount and the quality of the film that can be deposited without requiring the system to be shut down for cleaning.

New designs for shaping other surfaces of the dispersion head reduces contamination of those elements, and new designs for chamber panels decrease the deposition of byproducts on those surfaces, as well as other elements of the reactor. Decreasing deposition of byproducts increases the amount of thin film, and the quality of the film which can be deposited without requiring the system to be shut down. This increases the throughput of products in the deposition process, thereby increasing the efficiency of electronic device manufacture and lowering the cost.
