Patent number: 11823543Abstract: In a general aspect, motion is detected using wireless signals. In an example, a method includes receiving, at a wireless communication device, requests for the wireless communication device to transmit wireless signals, the requests initiated by a wireless sensing system. The method further includes transmitting a series of wireless signals from the wireless communication device in response to the requests, and detecting, at the wireless communication device, a trigger event after transmitting the series of wireless signals. The method additionally includes updating, by the wireless communication device, a state of the wireless communication device based on the trigger event, the updated state indicating that the wireless communication device is not enabled to transmit wireless signals in response to the requests from the wireless sensing system. The method also includes communicating, by the wireless communication device, the updated state of the wireless communication device to the wireless sensing system.Type: GrantFiled: August 5, 2021Date of Patent: November 21, 2023Assignee: Cognitive Systems Corp.Inventors: Christopher Beg, Tajinder Manku, Mohammad Omer

Patent number: 11576141Abstract: A method includes receiving a ground-truth motion indication from a measurement device. The ground-truth motion indication is a time series of locations and a corresponding indication of a motion state at each location of the time series of locations. The method also includes receiving a time series of detected motion states based on wireless signals communicated through a space over a time period by a wireless communication network comprising a plurality of wireless communication devices. The detected motion states for a time interval within the time series are compared to the ground-truth motion indication for the time interval within the time series to generate a time series of consistency scores. The consistency scores are processed to produce an aggregate motion-detection capability score at each location. The method also includes providing, for display as a graphical representation of motion-detection capability within the space, the aggregate motion-detection capability at each location.Type: GrantFiled: May 27, 2022Date of Patent: February 7, 2023Inventors: Christopher Beg, Paul Lock

Patent number: 11304254Abstract: In a general aspect, a motion sensing topology of a multi-access point (multi-AP) wireless communication network can be controlled. In some aspects, the multi-AP wireless communication network includes a first AP device, a second AP device, and a multi-AP controller. The multi-AP controller identifies a wireless communication topology, which includes identifying that a first client station device is associated with the first AP device. The multi-AP controller defines a motion sensing topology that is different from the wireless communication topology, and the motion sensing topology includes a wireless motion sensing link between the first client station device and the second AP device. The multi-AP controller initiates a motion sensing measurement based on the motion sensing topology, and the motion sensing measurement uses the wireless motion sensing link while the first client station device remains associated with the first AP device.Type: GrantFiled: August 31, 2021Date of Patent: April 12, 2022Assignee: Cognitive Systems Corp.Inventors: Mohammad Omer, Christopher Beg, William James Halford

Publication number: 20210278520Abstract: In a general aspect, motion is detected in an environment using wireless signals. In one example, a downlink high-efficiency PHY (HE-PHY) frame is received. The downlink HE-PHY frame is transmitted by an access point device to wireless communication devices residing inside an environment. An uplink orthogonal frequency-division multiple access (UL-OFDMA) transmission is subsequently received in response to the downlink HE-PHY frame. The UL-OFDMA transmission is transmitted by the wireless communication devices to the access point device. The UL-OFDMA transmission includes uplink HE-PHY frames simultaneously transmitted on respective resource units by the respective wireless communication devices. A motion data set is generated based on channel responses computed from the uplink HE-PHY frames. Each channel response is computed from a respective one of the uplink HE-PHY frames. Motion within the environment is analyzed based on the motion data set.Type: ApplicationFiled: February 22, 2021Publication date: September 9, 2021Applicant: Cognitive Systems Corp.Inventor: Christopher Beg

Patent number: 10928503Abstract: In a general aspect, motion is passively detected in an environment using wireless signals. In one example, a wireless sensor device that resides outside an environment receives wireless signals transmitted by wireless communication devices that reside inside the environment. One or more sets of motion data are generated, each having a corresponding set of link identifiers. The one or more sets of motion data may be based on beamforming reports in a first subset of the wireless signals and on physical (PHY) frames in a second subset of the wireless signals. The corresponding set of link identifiers may be based on address information in the first and second subsets of the wireless signals. A combined motion data set including the one or more sets of motion data is generated, and motion within the environment is analyzed based on the combined motion data set.Type: GrantFiled: March 3, 2020Date of Patent: February 23, 2021Assignee: Cognitive Systems Corp.Inventor: Christopher Beg
