  • Patent number: 10776930
    Abstract: Devices, systems, and methods for tracking a flying object, and displaying the tracked flying object with additional information regarding the flying object on a display. Digital images from one or more image sensors identify and track flying objects by the velocity and direction of movement, and can convey flight paths, corresponding collision alarms, warnings, or other information on the display.
    Type: Grant

  • Patent number: 4577561
    Abstract: A digital time fuze for providing an output pulse following a precise, specified time interval, wherein control means extract time interval data from a set signal, the control means thereafter providing a portion of a clock signal to a counter such that the length of the portion of the clock signal provided is determined by the time interval data. Counter means count the number of pulses in the clock signal portion to accumulate a timer count. In response to a start signal, the counter means counts down the timer count according to a count down clock which is provided by the control means and which is proportional to and derived from the clock signal. When the count reaches zero the output pulse is provided.
