摘要： An acoustic transducer array and method of baffle construction is presented to provide an improved array for use in underwater installations. The array is presented wherein a significant majority of the acoustic energy receiving surface is formed by lightweight acoustic baffling material while still maintaining a fully functional, fully populated array. The acoustic baffle constructed is incompressible and suitable for deep water operation while demonstrating both improved acoustic performance and positive buoyancy when necessary. In addition, the invention eliminates the non-uniform element to element spacing that occurs between sub-panels in similar arrays.

摘要： An acoustic pressure sensor includes a stack of one or more acoustically responsive elements which are contained within a housing. An external acoustic pressure to be sensed is transmitted to the stack via a diaphragm which exists in an end cap closing a top portion of the housing. The outer edge of the diaphragm is in direct contact with the outer edge of the housing. This area enhancement increases the basic sensitivity of the sensing stack without the need of a gap. The diaphragm allows flexure to occur in a controlled fashion. The housing is sealed at the top and bottom by end caps, the top end cap defining a diaphragm area, which diaphragm deflects to thereby apply pressure to the stack to convert acoustic signals into electrical signals.

摘要： A transducer includes an acoustic radiating member for generating acoustic energy in a transmitting medium and a driver member that is pivotally connected to the radiating member. The driver member is for urging movement of the radiating member, wherein such movement generates the energy. Pivoting of the driver member with respect to the radiating member relieves predetermined stress in the driver member. The radiating member may include, for example, a flat element such as a bar, plate or disk, or an I-shaped element. The driver element may include an electroactive material. The driver element may be connected to the radiating element by support apparatus that is fixedly coupled to the radiating element includes a screw having a predeterminedly contoured end that engages a complimentarily contoured recess connected to the driver element for permitting the pivoting. When the support apparatus includes a screw it may be adjusted for supplying a predetermined force on the driver element.

摘要： An efficient generator of electrical power employs groups of piezoelectric devices disposed in a radial manner about a centrally located cam. The cam, when rotated by a prime mover as a conventional source of mechanical energy, applies a periodic varying force to each piezoelectric device in a suitable sequence. The devices operate to respond to the rotation of the cam by having a cam follower coupled to each device via a spring, whereby a periodically varying force is applied to each piezoelectric device according to the cam surface and based on the rotation of the cam. Each device produces an output voltage according to the force applied to the device via the cam and the coupling between the device and the cam surface. Each device includes a stack of low loss piezoelectric plates connected together and responsive to the application of a mechanical stress to the stack to produce an electrical output.

摘要： An apparatus and method for testing variations in thicknesses of an optical part comprising an interferometer having a monochromatic light source (laser) which focuses a probe beam into the optical part being tested and detects a standing fringe pattern (Newton Fringes) arising through the interaction of two wavefronts produced by the reflection off the front and back surfaces of the optical part. These fringes may be circular or parallel depending upon the optical power of the probe beam. By observing the expansion and contractions of the interference rings, variations in the thickness of the part can be determined. By counting the number of interference peaks produced at the center of the fringe pattern, during relative movement between the optical part and the beam, a direct measurement of the optical part's thickness variations can be made. The direction of the thickness change is monitored by observing the slope of the intensity variation at the first ring of the interference pattern. A complete mapping of the variations in thickness of the part can be generated.
