Patent number: 10931346Abstract: Methods, systems, computer-readable media, and apparatuses for beam management in a wireless communication system are presented. In some embodiments, a beam management subsystem in a moveable device selects a first antenna array and forms a first beam using the first antenna array for sending and receiving communication signals from a base station or other transceiver. A communication signal processing subsystem receives a first communication signal via the first beam. Upon movement of the moveable device, an inertial navigation subsystem determines a rotation vector associated with the movement. In response to the inertial navigation subsystem determining the rotation vector, the beam management subsystem selects a second antenna array using the rotation vector and forms a second beam directed toward the base station using the second antenna array. The communication signal processing subsystem can receive a second communication signal via the second beam.Type: GrantFiled: February 21, 2019Date of Patent: February 23, 2021Assignee: QUALCOMM IncorporatedInventors: Russel Martin, Vidyut Naware

Patent number: 10743777Abstract: Disclosed embodiments pertain to cardiovascular parameter (e.g. heart rate) measurements when motion is present. Biometric sensor signal measurements may be obtained based on cardiovascular parameters of a user; and motion sensor signal measurements may be obtained based on user motion. An activity type may be determined based on the motion sensor signals. For example, when non-motion related frequencies in a frequency domain representation of the biometric sensor signal are obscured by user motion, an activity type may be determined based on the motion sensor signals. Further, based on the activity type, for each cardiovascular parameter (e.g. heart rate), a corresponding likely cardiovascular parameter value (e.g. a likely heart rate) may be determined. A corresponding fundamental frequency associated with the biometric sensor signal may then be determined for each cardiovascular parameter based on the motion sensor signal measurements and the corresponding likely cardiovascular parameter value.Type: GrantFiled: March 13, 2017Date of Patent: August 18, 2020Assignee: QUALCOMM IncorporatedInventors: Russel Martin, Shashank Narayanan, Hithesh Reddivari, Vidyut Naware, Igor Tchertkov, Joseph Czompo

Publication number: 20180316840Abstract: Disclosed are systems, devices, and methods for calibrating an optical image stabilization (OIS) module in a camera with a gyroscope. The OIS module is calibrated with a gyroscope in a two-step method. The first of the two-step method includes calibrating a lens to image sensor by determining a relationship between lens movement and image movement in the OIS module. The second of the two-step method includes calibrating a gyroscope to the image sensor by determining a relationship between gyroscope movement and image movement in the camera, where the camera includes the OIS module and the gyroscope. The relationship between lens movement and gyroscope movement can be determined to calibrate the OIS module with the gyroscope.Type: ApplicationFiled: August 22, 2017Publication date: November 1, 2018Inventor: Russel Martin

Patent number: 8487349Abstract: The invention describes in detail the structure of a CMOS image sensor pixel that senses color of impinging light without having absorbing filters placed on its surface. The color sensing is accomplished by having a vertical stack of three-charge detection nodes placed in the silicon bulk, which collect electrons depending on the depth of their generation. The small charge detection node capacitance and thus high sensitivity with low noise is achieved by using fully depleted, potential well forming, buried layers instead of undepleted junction electrodes. Two embodiments of contacting the buried layers without substantially increasing the node capacitances are presented.Type: GrantFiled: April 24, 2009Date of Patent: July 16, 2013Assignee: Foveon, Inc.Inventors: Jaroslav Hynecek, Richard B.
