Patent ID: 8608583

Claim:
An imaging system for determining the kinematics of one or more objects, comprising: a single ultrasonic trigger targeted toward a predetermined field of view through which the one or more objects pass, wherein the ultrasonic trigger emits a plurality of pulses with a predetermined time interval between each of the plurality of pulses to (a) prevent interference between emitted pulses and pulses that are reflected by the one or more objects in the predetermined field of view and (b) enable calculation of position and velocity of on or more objects in the predetermined field of view, wherein the predetermined time interval is greater than or equal to twice the distance from the ultrasonic trigger to the predetermined field of view; a camera operatively connected to the ultrasonic trigger to capture consecutive optical images of the one or more objects in the predetermined field of view; and a computational device operatively connected to the camera and ultrasonic trigger operable to compute the position and velocity of the one or more objects.
