  • Publication number: 20230297654
    Abstract: A method of authorizing a device action includes accessing a first baseline model that represents image characteristics of an authorized first user or object. The first baseline model is used as a basis for selecting a first number of sensing structures of a camera image sensor, wherein the first number of sensing structures of the camera image sensor is less than a total number of sensing structures of the camera image sensor. The selected first number of sensing structures of the camera image sensor is activated and a first image sensed by the activated first number of sensing structures is obtaining. The first image is compared with the first baseline model. A next round of authorization processing is activated when an amount of correlation between the first image and the first baseline model satisfies a threshold correlation amount.

    Abstract: A node in a wireless communication system coordinates multistatic radar measurements, wherein the node controls a plurality of wireless communication devices. Coordination involves obtaining an indication that a first sensing area located within a geographic area that is served by the node is to be sensed by a first radar signal. A first multistatic radar group of wireless communication devices selected from a participating group of the plurality of wireless communication devices and the node is formed, wherein the first multistatic radar group comprises at least one device for transmitting the first radar signal and at least two devices for receiving one or more reflections of the transmitted first radar signal. The first multistatic radar group is controlled to introduce the first radar signal into the first sensing area and to receive the one or more reflections of the introduced first radar signal.
