Publication number: 20190086482Abstract: An electromagnetic (EM) position tracking system identifies the pose of objects based on detected strength values of an EM field. To address distortions in the field, the system employs a pose sensor to provide a second pose of the mobile unit. Under conditions where no distortion in the EM field has been detected, the HMD applies a nominal set of corresponding weights to the EM pose data and the IMU pose data, respectively, and combines the weighted pose value to identify a combined pose of the mobile unit. In response to detecting conditions that indicate distortion in the EM field, the HMD can apply different weights to the EM pose data and IMU pose data to, for example increase the influence of the IMU pose data on the combined pose.Type: ApplicationFiled: September 18, 2017Publication date: March 21, 2019Inventors: Sherk Chung, Ian Atkinson, Advait Jain, Lucine Oganesian, Murphy Stein, Saket Patkar

Publication number: 20150227241Abstract: Systems and methods are provided that allow a touch sensor, such as a mutual capacitive touch panel, to switch from an operative transmit (TX) frequency at which the mutual capacitive touch panel is driven to an alternative TX frequency. When switching to an alternative TX frequency, an alternative baseline capacitance value corresponding to the alternative TX frequency may be utilized to determine whether a touch event has occurred on the mutual capacitive touch panel. Frame scans can be repeatedly performed at the operative TX frequency and the alternative TX frequency in rapid succession, and an average difference of the frame scans can be calculated and utilized to generate the alternative baseline capacitance value which may be insensitive to sudden ambient changes and moving touch events affecting the mutual touch capacitive panel.Type: ApplicationFiled: April 20, 2015Publication date: August 13, 2015Applicant: BROADCOM CORPORATIONInventors: Ian Atkinson, Sumant Ranganathan, Federico Cattivelli, Glen Weaver, John Walley, Tianhao Li, David Sobel

Patent number: 9051828Abstract: A system and method for producing bitumen or heavy oil from a clastic or carbonate reservoir. The mobility of the bitumen or heavy oil is increased by conductive heating to reduce the viscosity. The bitumen or heavy oil is heated to temperatures below the thermal cracking temperature of the bitumen or heavy oil. As the bitumen or heavy oil is produced, evolved gases or evaporated connate water or both form a gas chamber which acts to replace the volume of the produced fluid required for the gravity drainage process.Type: GrantFiled: June 17, 2011Date of Patent: June 9, 2015Assignee: Athabasca Oil Sands Corp.Inventors: Bryan Gould, Ian Atkinson, Bruce Roberts, Doug Beattie, Stephen D.

Patent number: 9031797Abstract: Methods and systems are described that provide for measuring flow properties of multiphase mixtures within a pipe carry gas-liquid hydrocarbons and water produced from oil-gas wells. The methods and systems may provide for a combination of a clamp-on ultrasonic gas flow meter to measure flow characteristics of a gas phase in a pipeline and a pulsed ultrasonic Doppler sensor(s) and/or an RF/microwave electromagnetic sensor(s) to measure flow characteristics of a liquid phase. The combination of sensors may provide for multiphase flow measurements under certain flow conditions, such as when the gas-liquid is flowing in a substantially horizontal pipeline, when the flow is stratified or is caused to be stratified and/or the like.Type: GrantFiled: September 17, 2008Date of Patent: May 12, 2015Assignee: Schlumberger Technology CorporationInventors: Songming Huang, Cheng-Gang Xie, Ian Atkinson
