U.S. Patents Awarded to Inventors in Oregon (March 7)

(Targeted News Service Via Acquire Media NewsEdge) Targeted News Service Targeted News Service ALEXANDRIA, Va., March 7 -- The following federal patents were awarded to inventors in Oregon.

*** Vascular Imaging Assigned Patent ALEXANDRIA, Va., March 7 -- Vascular Imaging, Rancho Cordova, Calif., has been assigned a patent (8,391,652) developed by Kenneth N. Bates, Beaverton, Ore., and Gil M. Vardi, Town & Country, Mo., for "systems and methods for minimally-invasive optical-acoustic imaging." The abstract of the patent published by the U.S. Patent and Trademark Office states: "An imaging guidewire can include optical fibers communicating light along the guidewire. At or near its distal end, one or more blazed or other fiber Bragg gratings (FBGs) directs light to a photoacoustic transducer material that provides ultrasonic imaging energy. Returned ultrasound is sensed by an FBG sensor. A responsive signal is optically communicated to the proximal end of the guidewire, and processed to develop a 2D or 3D image. The guidewire outer diameter is small enough such that an intravascular catheter can be passed over the guidewire. Techniques for improving ultrasound reception include using a high compliance material, resonating the ultrasound sensing transducer, using an attenuation-reducing coating and/or thickness, and/or using optical wavelength discrimination. Techniques for improving the ultrasound generating transducer include using a blazed FBG, designing the photoacoustic material thickness to enhance optical absorption. Techniques for distinguishing plaque or vulnerable plaque may enhance the displayed image." The patent application was filed on Oct. 31, 2011 (13/285,551).

The phase synthesis network includes two phase rotators that receive I and Q input LO signals, that receive a digital control signal, and that can adjust a phase and a gain in response to the digital control signal. An output of each of the phase rotators provides a respective output signal to a switch. The switch provides a selected one of the respective output signals for mixing with a predetermined one of the respective output signals. Two mixers mix signals from the phase rotators with an RF signal. Two analog-to-digital converters provide a respective digital signal representative of the output of the mixers. A baseband digital processor generates digital control signals that are provided to the phase rotators. The circuit has an output terminal configured to provide an output signal representative of the RF signal." The patent application was filed on Nov. 18, 2010 (12/949,679).

*** Impinj Assigned Patent ALEXANDRIA, Va., March 7 -- Impinj, Seattle, has been assigned a patent (8,391,785) developed by John D. Hyde, Corvallis, Ore., and Kurt E. Sundstrom, Woodinville, Wash., for an "interference rejection in RFID tags." The abstract of the patent published by the U.S. Patent and Trademark Office states: "RFID tags, tag circuits, and methods are provided that reject at least in part the distortion caused to wireless signals by interference in the environment. When the received RF wave is converted into an unfiltered input (971), a filtered output (972) is generated that does not include an artifact feature deriving from the distortion. The filtered output is used instead of the unfiltered input, which results in tag operation as if there were less interference in the environment, or none at all."

*** Digimarc Assigned Patent ALEXANDRIA, Va., March 7 -- Digimarc, Beaverton, Ore., has been assigned a patent (8,391,851) developed by Geoffrey B. Rhoads, West Linn, Ore., and Tony F. Rodriguez, Portland, Ore., for a "gestural techniques with wireless mobile phone devices." The abstract of the patent published by the U.S. Patent and Trademark Office states: "A user gestures with a wireless mobile phone device to control some aspect of its operation, or the operation of a remote system with which the device communicates. Application programs can solicit gestural information through a standardized set of interface protocols (e.g., API functions). One function, for example, solicits a running set of gesture data, and a complementary function discontinues the first function. Other functions solicit device movement data in particular directions. In some arrangements gesture data is sent by the wireless device to a remote system, which may issue a response that is dependent on the received gesture data. This response may also depend on other data obtained by the wireless device (e.g., obtained from an electronic or physical object, or sensed from the environment) and sent to the remote system. The wireless device may have different modes of interacting with users, to accommodate users with greater or lesser proficiency in gestural techniques. A variety of other features and arrangements are also detailed." The patent application was filed on May 25, 2007 (11/754,126).
