  • Synchronous motor control device
    Patent number: 7847500
    Abstract: Control technique of a synchronous motor capable of suppressing rotation pulsation caused by individual difference without complicating control algorithm is provided. A pulsation generator superimposing a pulsation component anticipated in advance to a current command for the synchronous motor and a correction current generator superimposing a correction signal substantially having an average value of zero to the current command are provided in a synchronous motor control device. By this configuration, the correction signal suppressing a distortion component is superimposed to a value of the current command with a simplified control configuration. Torque pulsation is suppressed by determining the correction signal from difference between a detection current and a command current.

  • Method and apparatus for bonded substrates
    Patent number: 7846813
    Abstract: A method for forming bonded substrates includes providing a plurality of substrates, each of which having a top surface. A characteristic length for each of the plurality of substrates is determined by: determining a topographical profile of the top surface of the substrate from an interior portion to an edge portion along a radial direction, determining a highest point of the profile, and defining the characteristic length as a distance from the highest point to the edge portion. A first substrate and a second substrate are selected where at least one of the first or the second substrates has a characteristic length shorter than a predetermined length. The first substrate and the second substrate are brought into contact and form bonded substrates, with the top surface of the first substrate facing the top surface of the second substrate.

  • Implantable transducer devices
    Patent number: 7848815
    Abstract: Receiver-stimulators comprise a nearly isotropic transducer assembly, demodulator circuitry, and at least two tissue contacting electrodes. Use of near isotropic transducers allows the devices to be implanted with less concern regarding the orientation relative to an acoustic energy source. Transducers or transducer elements having relatively small sizes, typically less than ½ the wavelength of the acoustic source, enhance isotropy. The use of single crystal piezoelectric materials enhance sensitivity.

  • Transaction accelerator for client-server communications systems
    Patent number: 7849134
    Abstract: In a network having transaction acceleration, for an accelerated transaction, a client directs a request to a client-side transaction handler that forwards the request to a server-side transaction handler, which in turn provides the request, or a representation thereof, to a server for responding to the request. The server sends the response to the server-side transaction handler, which forwards the response to the client-side transaction handler, which in turn provides the response to the client. Transactions are accelerated by the transaction handlers by storing segments of data used in the transactions in persistent segment storage accessible to the server-side transaction handler and in persistent segment storage accessible to the client-side transaction handler.

  • Accessing financial accounts with 3D bar code
    Patent number: 7845558
    Abstract: A three dimensional (3d) bar code can be affixed to a financial instrument (e.g., the credit card) sent to a consumer. Upon receiving the financial instrument, the consumer can acquire an image of the 3D bar code with an image capture device (e.g., a camera) of a mobile device. The mobile device can interpret or decode the 3D bar code to extract a web address. The mobile device may then send a request for a web page associated with the web address, which could be returned by the web server at the financial institution. The web page may allow the consumer to enter personal information. Upon receiving the personal information, the financial institution can verify the information, authenticate the consumer, and activate the financial account.
