Abstract
An apparatus for determining the relative height between two targets is disclosed. The present invention also discloses a method for determining the relative height between two targets; the method is substantially similar to the operational aspects of the device of the present invention. The method requires no angular measurements in order to determine the different height between the two targets, but rather only distance measurements that can be performed simply and accurately.The apparatus for determining the relative height between two targets a disclosed. The apparatus includes: two signal-responsive target-objects; a casing housing first and second measurement ports displaced a known distance from each other; at least one signaling module within the casing at each of the measurement ports, for signaling each of the two targets from both of the measurement ports; a distance measuring module coupled to each of the signaling modules for measuring the distance from each port to each target according to the respective signalings of the corresponding signaling modules; and a calculation module coupled to the signaling modules and to the distance measuring module and being responsive…
