Abstract: A telemetric spacial data recorder for the elaboration of a floor plan is described herein. The telemetric spacial data recorder includes a base module, a remote module, a hand held module and a data acquisition device. The distances between (a) the base module and the remote module, (b) the remote module and the hand held module and (c) the hand held module and a target point of a physical object are measured by electronic distance measuring devices. Similarly, the angle relations between, (i) the base module and the remote module, (ii) the remote module and the hand held module and (iii) the hand held module and the target point of a physical object are measured by electronic angle measuring devices. The measurement devices are linked to the data acquisition device which makes a geometrical construction to determine the relative spacial position of the target point of the physical surface with respect to the spacial position of the base module.

Abstract: A new ultrasonic transmission imaging apparatus is disclosed, which uses a new imaging method providing image focusing capability. The apparatus comprises an ultrasonic emitter producing substantially continuous coherent ultrasonic waves toward an object to be inspected. The apparatus further comprises an ultrasonic detectors array comprising a plurality of ultrasonic detectors receiving the object traversing ultrasonic waves to produce a plurality of series of electrical signals coming from the ultrasonic detectors, the electrical signals characterizing transmission of the ultrasonic waves through the object and being associated with series of image elements. The apparatus further comprises a signal vector components detector detecting signal vector components for each of the electrical signals. The apparatus further comprises a computer for controlling the apparatus and for receiving pairs of first and second signal vector component digital signals coming from the signal vector components detector.
