Patent number: 11693063Abstract: A system and method that can automatically select a frequency of a magnetic field in a magnetic tracking system. A magnetic tracking system emits an alternating magnetic field using a set of three frequencies. In the present approach, a transmitter is capable of generating multiple sets of three frequencies. A processor selects a first set of frequencies to use and causes the receiver to measure the amplitude of the magnetic field at those frequencies. In one embodiment, the frequency set having the lowest energy is selected. The processor then compares an estimated jitter at those frequencies to the actual jitter experienced using the frequencies. If the actual jitter exceeds the estimated jitter by a predetermined amount, the processor switches to a different set of frequencies and causes the receiver to measure the magnetic field at the new set of frequencies. The process may repeat using the additional sets of frequencies.Type: GrantFiled: June 7, 2022Date of Patent: July 4, 2023Assignee: PENUMBRA, INC.Inventors: Cameron J. Mahon, Oded Y.

Patent number: 11441924Abstract: The disclosure relates to a method for detecting a standstill of a vehicle, said method comprising a step of filtering, a step of normalizing and a step of observing. In the filtering step, an acceleration value in a first axis of the vehicle and a rotational speed value about a second axis of the vehicle, oriented orthogonally to the axis, are filtered using a filter specification in order to obtain a filtered acceleration value and a filtered rotational speed value. In the normalizing step, the filtered acceleration value and the filtered rotational speed value are normalized using a normalization specification in order to obtain a normalized acceleration value and a normalized rotational speed value. In the observation step, the normalized acceleration value and the normalized rotational speed value are observed using an observation specification in order to detect the standstill.Type: GrantFiled: January 24, 2018Date of Patent: September 13, 2022Assignee: Robert Bosch GmbHInventors: Kevin Hauck, Sebastian Roith

Patent number: 11443455Abstract: A scale and pose estimation method for a camera system is disclosed. Camera data for a scene acquired by the camera system is received. A rotation prior parameter characterizing a gravity direction is received. A scale prior parameter characterizing scale of the camera system is received. A cost of a cost function is calculated for a similarity transformation that is configured to encode a scale and pose of the camera system. The cost of the cost function is influenced by the rotation prior parameter and the scale prior parameter. A solved similarity transformation is determined upon calculating a cost for the cost function that is less than a threshold cost. An estimated scale and pose of the camera system is output based on the solved similarity transformation.Type: GrantFiled: January 15, 2020Date of Patent: September 13, 2022Assignee: Microsoft Technology Licensing, LLCInventors: Victor M.

Patent number: 11416903Abstract: A transaction arbiter system and method is disclosed which incorporates a merchant function database under control of a transaction arbiter that permits merchants to interact in an automated way with bids generated by other merchants. Rather than utilizing fixed price schedules as taught by the prior art, the present invention permits each merchant to define a set of functions which describe how the merchant will respond to a customer request-for-quote for a given product or service. These merchant functions interact with both the customer request-for-quote and the results of other merchant functions to generate a dynamic real-time bidding system which integrates competition among merchant bidders to achieve an optimal consumer price for a given product or service.Type: GrantFiled: April 4, 2019Date of Patent: August 16, 2022Assignee: PRICE SETTER LLCInventor: Jorge Arturo Maass

Patent number: 11410431Abstract: A vehicular control system includes a rear backup camera viewing at least rearward of the vehicle. With a trailer hitched to the vehicle, and based at least in part on image processing of captured image data during a backing-up maneuver, the image processor determines a distance between an axle of the trailer and the hitch of the vehicle and determines a trailer angle of the trailer hitched to the vehicle. During the backing-up maneuver of the trailer hitched to the vehicle, the vehicular control system determines a path of the trailer responsive to (i) a steering angle of the vehicle, (ii) the determined trailer angle of the trailer and (iii) the determined distance between the axle of the trailer and the hitch of the vehicle. The vehicular control system displays information to assist the driver in backing up the trailer hitched to the vehicle.Type: GrantFiled: February 1, 2021Date of Patent: August 9, 2022Assignee: MAGNA ELECTRONICS INC.Inventors: Sebastian Pliefke, Paul Jarmola, Thomas Wierich, Steven V.

Patent number: 11378403Abstract: Using geo-mapping data and only at least one inertial sensor, a Bayesian estimator uses at least one element of an uncorrected inertial navigation vector, of a moveable object on a surface, to estimate inertial navigation error information including corresponding statistical information. The estimated inertial navigation error information is used to error correct the uncorrected inertial navigation vector. The Bayesian filter also predicts inertial navigation error information, including corresponding statistical information, for a future time instance when a next uncorrected inertial navigation vector will be obtained.Type: GrantFiled: July 26, 2019Date of Patent: July 5, 2022Assignee: Honeywell International Inc.Inventors: Jindrich Dunik, Milos Sotak, Milos Vesely, Wesley J.

Patent number: 11366236Abstract: A signal of opportunity (SOP)-aided inertial navigation system (INS) framework provides various technical solutions to technical problems facing GNSS implementations. A mobile receiver, whether handheld or vehicle-mounted, has access to Global Navigation Satellite System (GNSS) signals, multiple unknown terrestrial SOPs, and IMU measurements, which are used to estimate receiver states. When GNSS signals become unreliable, the mobile receiver continues to navigate using the SOP-aided INS. The SOP-aided INS produces bounded estimation errors in the absence of GNSS signals, and the bounds are dependent on the quantity and quality of exploited SOPs.Type: GrantFiled: September 22, 2017Date of Patent: June 21, 2022Assignee: THE REGENTS OF THE UNIVERSITY OF CALIFORNIAInventors: Zak M.
