Abstract: An imaging system and method provides for the automatic leveling of a hologram detector system. A detector system must be precisely oriented in a proper predetermined orientation. The present invention senses the orientation of a plate to which the detector system is mounted and adjusts driver motors to maintain the detector system at a desired predetermined orientation. In an exemplary embodiment, orientation sensors form a feedback loop to a servo controller to control the position of the motors and thus maintain the detector system at the predetermined orientation. In another aspect of the invention, the patient table may be repositioned with respect to the imaging system. The patient is positioned on a table and imaging performed. If an object of interest is detected, the patient table may be independently repositioned in three orthogonal directions such that the object of interest coincides with an axis of rotation of the patient table. In this manner, the object of interest stays within a predetermined focal plane as the patient is rotated such that the object may be viewed from various angles.

Abstract: A device or tool (10) to place objects such as speakers at an equal distance from a reference point (cc) has a supporting base (100) with a center to be placed at the reference point. Beam generators (130, 135) are mounted on an azimuth locating mechanism (105) rotatable on said base. The beam generators generate light beams which are first directed at one speaker and their relative location is fixed. The mechanism is rotated sequentially toward each predetermined location for the other speakers and the beams impinging on the speakers are used to locate their optimal positions.

Abstract: An adaptive beamforming system for broadband sonar with a convergence time on the order of the pulse duration and effective interference nulling capabilities which enhance desirable echoes. The method uses an element based time implementation algorithm in which beam data that is formed in the direction of each interferer is successively subtracted from the element data using an adaptive FIR filter (16). The system can be applied to impulsive source sonar data and passive sonar data.

Abstract: The present invention pertains to a modular device to be inserted into a vehicle bumper and a support for securing said module to the bumper. The support is solidly fixed to the internal face of the bumper, so that the module can be inserted from outside. The bumper presents a corresponding bore, into which the module head is inserted until its surface is flush with the external side of the bumper. The inventive module is an ultrasound sensor intended to measure the distance to a vehicle. As only the module head is visible, but not the fastening hardware, the device is not aesthetically disturbing in its appearance.

Abstract: A general-purpose, adaptable, device for interfacing acoustic and ultrasonic transducers to circuits for high resolution distance and motion measurement, and two-way communication. A generator signal (52) synchronizes to a sensing transducer signal (21), or a reference signal (23). A detector (20) provides a detected-cycle signal (22) and a detected-amplitude signal (24) from the signal being detected. Comparator (30) creates a comparator signal (32) from the detected-cycle and generator signals. A sustaining circuit provides flywheel operation during gaps. A driver (60) drives a radiating transducer. Options include: single or dual transducer operation, continuous or pulsed-burst operation, optimum frequency communication using low cost piezoelectric transducers, sonic wave frequency scanning, phase and amplitude modulation and demodulation, fast synchronization, detected vs reference signal comparison, and self-testing.
