  • Patent number: 7491437
    Abstract: A system, method, and process for fabricating solid surface inserts for solid surface materials is provided. The solid surface inserts provide additional decorative and/or functional elements to a solid surface material. The solid surface inserts are designed and fabricated to capture the salient features of a desired design in order to integrate the desired design into the solid surface base to create an assembled solid surface. To create the assembled solid surface, the solid surface base has a pocket formed to accept the solid surface inserts. Then, the solid surface inserts are fabricated from other solid surface materials. The fabricated solid surface inserts are then assembled, interlocked, and secured, either with each other and/or with the solid surface base, using an adhesive to create the assembled solid surface.

  • Patent number: 7492008
    Abstract: A method for forming a semiconductor-on-insulator (SOI) substrate is described incorporating the steps of heating a substrate, implanting oxygen into a heated substrate, cooling the substrate, implanting into a cooled substrate and annealing. The steps of implanting may be at several energies to provide a plurality of depths and corresponding buried damaged regions. Prior to implanting, the step of cleaning the substrate surface and/or forming a patterned mask thereon may be performed. The invention overcomes the problem of raising the quality of buried oxide and its properties such as surface roughness, uniform thickness and breakdown voltage Vbd.

  • Patent number: 7491931
    Abstract: In various aspects, ion sources, mass spectrometer systems, and a power supply circuit coupled to a feedback circuit are provided. A power supply is provided that includes at least the power supply circuit and is operable to transfer charge to a load. The feedback circuit is responsive to a DC component of an output voltage supplied by the power supply in a first feedback loop and an AC component of the output voltage in a second feedback loop to produce a feedback signal representative of at least one of: a value of the output voltage before a charge transfer from a capacitor of the power supply to a load; the value of the output voltage during the charge transfer from the capacitor of the power supply to the load; or the value of the output voltage after the charge transfer from the capacitor of the power supply to the load.

  • Patent number: 7492927
    Abstract: In the described embodiment, methods and systems for processing facial image data for use in animation are described. In one embodiment, a system is provided that illuminates a face with illumination that is sufficient to enable the simultaneous capture of both structure data, e.g. a range or depth map, and reflectance properties, e.g. the diffuse reflectance of a subject's face. This captured information can then be used for various facial animation operations, among which are included expression recognition and expression transformation.

  • Patent number: 7493420
    Abstract: Safe mode operation for portable devices supporting multiple protocols includes a portable device that supports multiple protocols, such as a base functionality protocol and an enhanced functionality protocol, reporting to a host device that the portable device supports only a single protocol (e.g., the base functionality protocol). This single protocol will be used for subsequent communication between the host device and the portable device. This reporting to the host device that the portable device supports only a single protocol can be triggered, for example, by an appropriate button(s) on the portable device being pressed when the portable device is powered on.

  • Patent number: 7490528
    Abstract: An electronic transmission range selection (ETRS) system for shifting a transmission range of a transmission includes an electro-mechanical park inhibit assembly that operates to disallow the ETRS system from shifting from an Out-of-Park mode to a Park mode under certain circumstances. The park inhibit assembly includes a follower having a recess defined thereon and slidably disposed within a follower bore. In one embodiment a selectively energizable solenoid assembly is mounted substantially perpendicular to the follower and operates to bias a ball into the recess when energized thereby locking the ETRS system in the Out-of-Park mode. In another embodiment the park inhibit assembly includes a selectively energizable motor assembly mounted substantially perpendicular to the follower. The motor assembly operates to enforce the Park and Out-of-Park mode of the ETRS system.

  • Patent number: 7490603
    Abstract: The need for the delivery of insulin by injection can be reduced or eliminated by delivering an aerosolized monomeric insulin formulation. Repeatability of dosing and more particularly the repeatability of the blood concentration versus time profile is improved relative to regular insulin. The blood concentration versus time profile is substantially unaffected by specific aspects of the patient's breathing maneuver at delivery. Further, the rate at which blood glucose is lowered is increased by the use of monomeric insulin. Particles of insulin and in particular monomeric insulin delivered to the surface of lung tissue will be absorbed into the circulatory system. The monomeric insulin may be a dry powder but is preferably in a liquid formulation delivered to the patient from a hand-held, self-contained device which automatically releases an aerosolized burst of formulation.

  • Patent number: 7492728
    Abstract: An improved system and method is disclosed for call handling in a packet network such as a CDMA, UMTS, GSM, and other networks similarly configured. The system may include an anchor media gateway that remains in a communication path even if the call has been handed off to another media gateway. The anchor media gateway includes first and second ports for establishing first and second links to transfer packet communications to and from the first and second entities, respectively. First and second packet connections are provided for interconnecting the first and second links, respectively, to an audio server. A third link connected to the audio server and is provided for transferring packet communications to and from the third entity. The audio server manipulates the packet communications received from the first, second, and third entities and provides the manipulated packet communications to the first, second, and third entities.

  • Patent number: 7493341
    Abstract: Exemplary embodiments of the present invention provide methods and systems for supplying rich multimedia metadata usable to generate, e.g., sophisticated entertainment user interfaces in the home. These methods and systems can be implemented as a server-based software application that feeds multiple, diverse clients. The server functionality could be distributed, even co-located physically with one or more clients, or centralized. The server aggregates, filters, validates, augments and links metadata from disparate sources. The server transforms the metadata into a more manageable and extensible internal format. The server communicates with client devices using a schema-independent protocol, providing metadata in the appropriate format that suites the clients needs.

  • Patent number: 7491756
    Abstract: The present invention relates to multi-part coating compositions that comprise a first part which is an asphalt emulsion comprising water, asphalt, and a dispersion system and a second part which is a liquid polymer composition that lacks water. The asphalt emulsion and liquid polymer composition are combined in situ to provide a coating that has fast dry characteristics, and that quickly develops good water-resistance. Such compositions are useful as coatings on metal, wood, and other surfaces, where fast drying characteristics are important. Such compositions are particularly useful as coatings on substrates where early water-resistance of the coating is important, such as those surfaces which are routinely exposed to the outdoors.
