  • Publication number: 20200341114
    Abstract: An identification system includes a radar sensor configured to generate a time-domain or frequency-domain signal representative of electromagnetic waves reflected from one or more objects within a three-dimensional space over a period of time and a computation engine executing on one or more processors. The computation engine is configured to process the time-domain or frequency-domain signal to generate range and velocity data indicating motion by a living subject within the three-dimensional space. The computation engine is further configured to identify, based at least on the range and velocity data indicating the motion by the living subject, the living subject and output an indication of an identity of the living subject.

  • Patent number: 4521865
    Abstract: A signal consisting of a sequence of contiguous line segments is generated to simulate a function. First programmable inputs define a first parameter (duration) corresponding to each of the line segments. Control signals are generated which are representative of each of the first parameters. A reference voltage representative of a second parameter (end point) corresponding to each of the line segments is generated and stored. The output signal comprises a portion representative of each of the line segments. Each portion is generated over a period determined by the control signal corresponding to the line segment which the portion represents, has an initial value determined by the stored reference voltage corresponding to the previous line segment, and a final value determined by the reference voltage corresponding to the line segment which the portion represents.
