Patent number: 11916408Abstract: Disclosed herein is a wireless power delivery system including: a wireless power generation unit (GU) including: a GU antenna array; and a GU wireless communication circuit; and one or more recovery units (RUs), wherein each RU includes: an RU antenna array; and an RU wireless communication circuit. The GU antenna array is configured to use volumetric refocusing to scan the area for the one or more RUs by sweeping a wireless scan signal to be captured by the RU antenna array. The RU antenna array receives the wireless scan signal, the RU wireless communication unit is configured to transmit a wireless signal back to the GU wireless communication unit. The GU is configured to record the focal coordinates of each RU based upon the signal received by the GU from each RU. The GU is configured to emit a wireless power signal to the recorded focal coordinates of each RU.Type: GrantFiled: January 11, 2022Date of Patent: February 27, 2024Assignee: GuRu Wireless, Inc.Inventors: Behrooz Abiri, Seyed Ali Hajimiri, Mark Lewis

Patent number: 11705871Abstract: An RF power detector adapted to detect an RF power of an RF signal, includes, in part, an antenna adapted to receive the RF signal, a narrow-band RF power converter adapted to convert the RF signal to a DC signal, an accelerometer, and a magnetometer. The accelerometer and magnetometer are adapted to determine the orientation and location of the power detector. The power detector optionally includes a gyroscope. The narrow-band RF power converter may be a rectifier tuned to the frequency of the RF signal. The power detector optionally includes an indicator adapted to provide information representative of the amount of the DC power of the DC signal, as well as position and orientation of the power detector. The power detector may be adapted to be inserted into a mobile device so as to provide the information about the amount of DC power, orientation and position to the mobile device.Type: GrantFiled: December 28, 2021Date of Patent: July 18, 2023Assignee: GuRu Wireless, Inc.Inventors: Seyed Ali Hajimiri, Behrooz Abiri, Florian Bohn

Patent number: 11659355Abstract: Wireless power transfer systems and methods for focusing wireless power transfer arrays are disclosed. One embodiment includes a wireless power generating unit (GU) including a processing system configured to focus the RF power sources by: sending control signals to the control circuitry to perform a plurality of sweeps using each of a plurality of different basis masks; receiving a message from a RU containing a report based upon received power measurements made by the RU; and sending control signals to focus the RF power sources based on the received message from the RU. Furthermore, each sweep includes performing a phase sweep across a phase sweep range at a plurality of phase step increments with respect to a first group of RF power sources identified in a basis mask, where the first group of RF power sources comprises a plurality of RF power sources.Type: GrantFiled: November 20, 2020Date of Patent: May 23, 2023Assignee: GuRu Wireless, Inc.Inventors: Seyed Ali Hajimiri, Behrooz Abiri, Florian Bohn, Farhud Tebbi

Patent number: 11629960Abstract: A method of determining the orientation of a device having disposed therein, in part, an inertia measurement unit, a phased array receiver, and a controller, includes, in part, detecting the difference between phases of an RF signal received by at least a pair of receive elements of the phased array receiver, determining the angle of incidence of the RF signal from the phase difference, using the angle of incidence to determine the projection of a vector on a plane of an array of transmitters transmitting the RF signal, and determining the yaw of the device from the projection of the vector. The vector is a three-dimensional vector representative of the orientation of the plane of the phased array receivers relative to the plane of the array of transmitters transmitting the RF signal.Type: GrantFiled: September 20, 2019Date of Patent: April 18, 2023Assignee: GuRu Wireless, Inc.Inventors: Marc-Angelo Carino, Seyed Ali Hajimiri, Behrooz Abiri, Florian Bohn

Patent number: 11322990Abstract: A method of RF power delivery includes, in part, transmitting a first group of RF signals having a first group of phases to a first mobile device during a first time period. The first mobile device has a first position and a first orientation during the first time period. The method further includes, in part, transmitting a second group of RF signals having a second group of phases to the first mobile device during a second time period. The second group of phases are determined in accordance with a second position and a second orientation of the first mobile device during the second time period. The second position and second orientation are determined using sensors disposed in the first mobile device and transmitted via a wireless communications channel to an RF power generating unit transmitting the first and second group of RF signals.Type: GrantFiled: March 27, 2019Date of Patent: May 3, 2022Assignee: Guru Wireless, Inc.Inventors: Seyed Ali Hajimiri, Behrooz Abiri, Farhud Tebbi

Patent number: 11172322Abstract: A wireless service delivery system determines the position of a device requesting the wireless service and delivers a wireless service to the device if the device's position is determined to fall within a predefined region of a space. The wireless service delivery may deliver no service or a lower quality/slower service if the device is determined to fall outside the predefined region of the space. The coordinates of the points along the perimeter of the predefined region are stored in a memory and are optionally established during a setup phase by moving a localization device along the perimeter of the region of the space.Type: GrantFiled: November 29, 2018Date of Patent: November 9, 2021Assignee: GuRu Wireless, Inc.Inventors: Behrooz Abiri, Florian Bohn, Seyed Ali Hajimiri
