Based at least in part on the first frequency band having the greater SPR and the first frequency band having the loading volume above the threshold, a dynamic change of a user device connection to the first frequency band for access to a first wireless telecommunications network is delayed.Type: GrantFiled: June 17, 2020Date of Patent: September 21, 2021Assignee: T-MOBILE INNOVATIONS LLCInventor: Sreekar Marupaduga

Patent number: 11128055Abstract: Systems and devices relating to antennas and antenna systems. A horizontal omnidirectional antenna has two dipoles with each dipole being in a V-configuration such that the arms of the dipole define an angle. The two dipoles are arranged so that the angles defined by each of the dipoles face and open toward each other. The horizontal omnidirectional antenna can be configured to operate with specific frequency bands. By nesting two instances of this antenna, with one configured for high band frequencies and one configured for low band frequencies, a dualband omnidirectional antenna can be obtained. The resulting antenna is physically compact and can be used in small MIMO systems along with vertical omnidirectional antennas.Type: GrantFiled: May 31, 2017Date of Patent: September 21, 2021Assignee: Communication Components Antenna Inc.Inventors: Nasrin Hojjat, Sadegh Farzaneh, Minya Gavrilovic, Des Bromley, Parna Kazerani

Patent number: 11101568Abstract: An antenna assembly includes a first antenna having a first length in a height direction, and a second antenna including a reflective surface having a second length in the height direction greater than or equal to the first length. The reflective surface of the second antenna is oriented towards a primary signal reception direction of the first antenna, and the reflective surface is configured to reflect a communication signal associated with the first antenna in order to increase a directional gain of the first antenna in the primary signal reception direction.Type: GrantFiled: March 27, 2020Date of Patent: August 24, 2021Inventors: Masashi Wakui, Antony Mihalopoulos

Patent number: 11047702Abstract: An electronic device may be provided with control circuitry for locating lost items. The control circuitry may determine where an item is located and may use the display or other output device to guide a user to the item. The display may display a visual guide such as an arrow, a sphere, a circle, a compass, or other visual aid that points the user in the direction of the item. The control circuitry may change the size or other characteristic of the visual aid on the display as the distance between the electronic device and the object changes. The control circuitry may change the location of the visual aid on the display as the orientation of the electronic device relative to the object changes. The display may overlay the visual aid onto live images of the user's surroundings as they are captured by a camera.Type: GrantFiled: September 6, 2017Date of Patent: June 29, 2021Assignee: Apple Inc.Inventors: Adam S.

Patent number: 11041936Abstract: An autonomously reconfigurable surface for adaptive antenna nulling includes a lattice of electrically conductive elements (which may be embodied as crossed metallic dipoles) mounted on a thin and preferably conformal surface and aperiodically loaded with reactance tuning elements and/or RF (and typically high power) sensing circuits. Additional elements mounted on this surface include analog to digital convertors (ADCs), digital to analog convertors (DACs), and microcontroller(s). The analog outputs of the DACs are networked to reactance tuning elements via, for example, a network of thin copper traces. The analog inputs of the ADCs are networked to the RF sensing circuits via a network, for example, of thin copper traces. The digital outputs of ADCs and the digital inputs of DACs are networked to microcontroller(s) via a network, for example, of thin copper traces.Type: GrantFiled: October 4, 2018Date of Patent: June 22, 2021Assignee: HRL Laboratories, LLCInventors: Walter S.
