A Silicon Oxide overcoat covers the transducer and a Silicon Nitride layer covers the Silicon Oxide overcoat within only the center and edge regions. The thickness of the Silicon Nitride layer is sufficient for providing a frequency modification to the acoustic wave within the center region and is optimized with a positioning of a Titanium strip within each of the opposing edge regions. The Titanium strip reduces the acoustic wave velocity within the edge regions with the velocity in the edge regions being less than the wave velocity within the transducer center region. | 2012-06-28 |
20120161578 | METHOD OF DRIVING PIEZOELECTRIC DEVICE - Provided is a method of driving a piezoelectric device including a piezoelectric material having at least two phase transition temperatures and is polarized in one of thickness directions, and electrodes disposed on both end surfaces of the piezoelectric material in a direction orthogonal to the polarized direction, the method including: applying an alternating electric field to the piezoelectric device by an electric field applying unit; and applying a bias electric field in accordance with a variation of a coercive electric field due to temperature variation so that an absolute value of an electric field in a direction opposite to the polarized direction in the alternating electric field applied by the electric field applying unit becomes smaller than the coercive electric field and so that a polarization of the piezoelectric material is not reversed by the electric field in the direction opposite to the polarized direction. | 2012-06-28 |
20120161579 | TUBULAR ACTUATORS UTILIZING ACTIVE MATERIAL ACTIVATION - A tubular actuator including a flexible tube or roll, operable to shift between first and second configurations so as to define a stroke, and utilizing active material activation to produce, modify, and/or retain the stroke. | 2012-06-28 |
20120161580 | BANDWIDTH ENHANCING LIQUID COUPLED PIEZOELECTRIC SENSOR APPARATUS AND METHOD OF USE THEREOF - Sensors used in mapping strata beneath a marine body are described, such as in a flexible neutrally buoyant towed array. A first sensor is a motion sensor including a conductive liquid in a chamber between a rigid tube and a piezoelectric motion film circumferentially wrapped about the tube. The liquid transfer signal from a gravitational bottom of the sensor while rejecting water body surface reflected noise. A second sensor is a traditional acoustic sensor or a novel acoustic sensor using a piezoelectric sensor mounted with a thin film separation layer of flexible microspheres on a rigid substrate. Combinations of motion sensors and acoustic sensors co-located in a rigid streamer housing sections are provided. | 2012-06-28 |
20120161581 | ACOUSTIC TRANSDUCER - An acoustic transducer includes a ring oscillator. The ring oscillator includes: a first cushioning material; a pair of first and second annular members that are laminated in an axial direction thereof with the first cushioning material therebetween, each of the annular members having first and second ends in a circumferential direction thereof, and a notch portion formed between the first and second end; a first connecting portion that connects the first end of the first annular member and the second end of the second annular member; and a second connecting portion that connects the second end of the first annular member and the first end of the second annular member. | 2012-06-28 |
