  • Patent number: 11144752
    Abstract: A method for verifying authenticity of a physical document includes receiving an image of a physical document to be authenticated including the physical document and a background. A pre-processed image is produced that includes the physical document separated from the background. The producing includes separating the physical document from the background by semantic segmentation utilizing an artificial neural network trained using an augmented dataset generated by applying geometric transformations over different backgrounds. Features of the pre-processed image are extracted to determine a document type. In response to determining the document type of the physical document, the method includes verifying, utilizing a machine learning classifier, whether the physical document is authentic based on the extracted features relative to expected features for the corresponding document type. An indication of whether the physical document is authentic based on the verifying is generated.

  • Publication number: 20210289428
    Abstract: A base station for a multiple-input, multiple-output (MIMO) array receives a message that includes information identifying the transmitting and receiving nodes. Based on whether the base station has access to up-to-date channel covariance matrices for the nodes, the base station selectively performs a clear channel assessment in an unlicensed frequency band concurrently with placing nulls in directions associated with the nodes. In some cases, the up-to-date channel covariance matrices are used to place nulls in the directions associated with the nodes concurrently with performing the clear channel assessment in response to the up-to-date channel covariance matrices being available to the base station. Placement of nulls in the directions associated with the nodes is bypassed in response to the up-to-date channel covariance matrices not being available to the base station.

  • Patent number: 11112522
    Abstract: Self-testing proximity testing systems and corresponding methods are discussed herein and can include a proximity probe and controller in electrical communication via a cable. A self-testing subsystem can be in communication with the controller and configured to determine whether proximity probes and cables assembled with a controller are compatible or incompatible. The self-testing subsystem can place a known impedance in electrical communication with the controller, modifying a proximity signal output by the controller. When the modified proximity signal differs from a predicted proximity signal by greater than or equal to a threshold amount, the self-testing subsystem can output a first indication indicating that incompatible proximity probes and cables are assembled with a controller.

  • Patent number: 10944664
    Abstract: A base station provides, a first number of probe packets to an access point for transmission to a user equipment over an access network path. The base station receives information indicating a bandwidth of the access network path estimated by the user equipment. The base station determines which of the base station or the access point to use for communication with the user equipment based on the bandwidth. The user equipment receives a second number of packets over an air interface and determines inter-arrival packet delays for the second number of probe packets. The user equipment estimates the bandwidth of the air interface based on the inter-arrival packet delays, the first number, and a time interval for transmission of the first number of probe packets. The user equipment transmits information indicating the bandwidth.
