Patent number: 11340342Abstract: A high performance, low-cost automotive radar is designed by mounting receivers around a 3D printed Luneburg lens. With this configuration, the antenna radiation pattern is maintained for all angles, (which means no beam deformation). Further, the present radar is capable of performing detection at all azimuth and elevation angles with high angle resolution and broadband operation. The radar adaptively adjusts its spatial sensing pattern, sweeping frequency band, pulse repetition frequency and coherent processing interval according to the environment.

Patent number: 11159380Abstract: This disclosure provides systems and methods for routing and topology management of computer networks with steerable beam antennas. A network controller can generate an input graph for a first time period. The input graph can have a plurality of vertices each representing a respective moving node and a plurality of edges each representing a possible link between a pair of moving nodes. The input graph also can include corresponding location information for each of the moving nodes during the first time period. A solver module can receive information corresponding to the input graph, a maximum degree for each vertex in the input graph, and a set of provisioned network flows. The solver module can determine a subgraph representing a network topology based on the input graph, the maximum degree for each vertex in the input graph, and the set of provisioned network flows, such that a number of edges associated with each vertex in the subgraph does not exceed the maximum degree for each vertex.Type: GrantFiled: January 7, 2019Date of Patent: October 26, 2021Assignee: Waymo LLCInventors: David Mandle, Yaoyao Gu, Brian Barritt, Tatiana Kichkaylo

Patent number: 11131602Abstract: An intermediate signal is separated into a first sub-signal and a second sub-signal according to a separation coefficient having a known real value. The first sub-signal is delivered to a first photonic circuit containing at least one photonic device to be characterized and a first photonic part. The second sub-signal is delivered to a second photonic circuit containing a second photonic part having a same transfer function as the first photonic part but lacking the at least one photonic device. Optical output signals from the first and second photonic circuits are converted into first and second electrical signals. Losses of the at least one photonic device are determined from processing the electrical signals and from the known real value of the separation coefficient.Type: GrantFiled: November 13, 2018Date of Patent: September 28, 2021Assignee: STMicroelectronics (Crolles 2) SASInventors: Patrick Le Maitre, Jean-Francois Carpentier

Patent number: 11125848Abstract: Systems and methods are provided to simultaneously determine both angle of arrival (AoA) and angle of departure (AoD) of a signal transmitted between two or more radio frequency (RF)-enabled wireless devices (e.g., such as BLE modules). The disclosed systems and methods may be so implemented in one embodiment to determine AoD even in the case where the transmitting wireless device is at the same time operating in a departure (or AoD) transmitting mode by transmitting a RF signal from multiple antenna elements of at least one switched antenna array using a given switching pattern or sequence implemented by an array switch.Type: GrantFiled: July 28, 2017Date of Patent: September 21, 2021Assignee: Silicon Laboratories Inc.Inventor: Jere M. Knaappila

Patent number: 11115138Abstract: Techniques are disclosed for detecting obstruction of a device's antenna(s) and then changing an operation of the device. A transmission time at which an antenna of an electronic device transmitted a signal can be identified. A response signal can be detected that was received at a receiver of the electronic device subsequent to the transmission time. Based on the response signal and on the transmission time, one or more response-signal characteristics can be determined. Based on the one or more response-signal characteristics, it can be determined that the antenna or that another antenna of the electronic device is at least partly blocked from emitting or receiving signals. In response to determining that the antenna is at least partly blocked, a changed type of operation can be identified, and the changed type of operation can be performed.Type: GrantFiled: February 11, 2020Date of Patent: September 7, 2021Assignee: Apple Inc.Inventors: Celalettin U. Bas, Joachim S. Hammerschmidt, Ming Lei, Pengcheng Zhan

Patent number: 11108475Abstract: An example method for testing a base station that supports multi-carrier transmission using multiple transceiver units comprises transmitting an interfering test signal in one or more transmit bands for the base station apparatus, using the multiple transceiver units and the antenna array, where the interfering test signal has a total EIRP at least approximately equal to the sum of the respective rated maximum EIRPs for each of the predetermined number of simultaneous carriers. This example method further comprises transmitting a desired test signal to the base station apparatus, in a receive band for the base station apparatus, using a test signal generator and a test antenna separate from the base station apparatus, and evaluating a receiver sensitivity for the base station apparatus, based on the desired test signal, while the interfering test signal is being transmitted.Type: GrantFiled: August 11, 2017Date of Patent: August 31, 2021Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Thomas Chapman, Asif Ali Khan

Patent number: RE49001Abstract: An access point that performs dynamic selection of an electronic-device-specific receive antenna pattern of an antenna for use when receiving a frame from an electronic device in a WLAN is described. In particular, during operation the access point may determine the receive antenna pattern of the antenna that is used when receiving the frame from the electronic device. Then, the access point may store, in memory, information that specifies the receive antenna pattern. Moreover, when the access point predicts that the electronic device will transmit a frame to the access point within a subsequent time interval, the access point may select the receive antenna pattern and may set an antenna pattern of the antenna to the receive antenna pattern. Next, the access point may receive the frame from the electronic device using the receive antenna pattern.Type: GrantFiled: February 20, 2020Date of Patent: March 29, 2022Assignee: ARRIS Enterprises LLCInventors: Shuai Xiao, Chonggang Li, Huaqing Zeng, Michael Ren
