摘要： A system shines a series of light stripes across an area. A target object passes through the area and light is reflected to the system from the light stripes as it passes through. Based on the timing of the received light from each of the light stripes, the system calculates the position and velocity of the target object.

摘要： A vehicle measurement station utilizing at least one displacement sensor systems disposed on each opposite side of a sensor region of a vehicle inspection lane to acquire measurement data, associated with a vehicle passing through the sensor region. Each displacement sensor system is configured to acquire measurement data along at least three discrete and vertically spaced measurement axis in response to a trigger signal indicating the presence of a vehicle moving through the inspection lane. A processing system receives the acquired data for evaluation, identification of outlier data points, and for determining a measurement associated with a characteristic of the moving vehicle.

摘要： A speed measuring device includes an adapter pad, two mounting boards, a guide plate, and two speed detection units. The adapter pad includes a base plate and a joint plate adapted to be assembled on a mounting rack of a ball pitching machine. Each mounting board is installed on one of two sides of the base plate and includes spaced first and second sections. The guide plate is assembled on the first sections of the mounting boards. A width between the moveable mounting boards relative to the base plate and longitudinal positions of the two mounting boards relative to the ball pitching machine are respectively adjustable. The speed detection units mounted on inner surfaces of the second sections of the mounting boards define a space through which a ball passes for detecting speed of the ball shot by the ball pitching machine.
