摘要： A multi-dimensional transducer array has pitch along one dimension less than the pitch along a second dimension. The multi-dimensional transducer array with the same or different pitch is manufactured from a plurality of modules. Each of the modules are separately diced and then aligned and combined. Elements of a transducer array are used for isolating a transmit channel from a receive channel. Separate signal lines or traces are provided individually for each element on opposite sides of each element. A transmit channel may connect to one electrode on an element, and the receive channel may connect to an opposite electrode on the element. A multi-dimensional array is provided for time division multiplex processing. A probe houses the multi-dimensional array and a multiplexer.

摘要： Matching layers are provided, including: electrically conductive acoustic matching layers, methods for conducting electric current through matching layers, methods for manufacturing multi-dimensional arrays using conductive matching layers, and multi-dimensional arrays with electrically conducting matching layers. Matching layers with conductors aligned for providing electrical conduction through the thickness or range dimension of the matching layer are provided. For example, vias, aligned magnetic particles, or conductive films at least partially or entirely within the matching layer of each element allow electrical conduction from the transducer material to a ground foil or flex circuit. By using multiple electrical conductive matching layers, a gradation in acoustic impedance for better matching is provided while allowing dicing of the entire stack, including the matching layers and the electroceramic material, in one step.

摘要： A one piece layer is provided for protecting the flat surface of a cross-country or telemark ski binding. The layer is a single die-cut self-adherent film to precisely fit the binding plate. The layer is made of a non-stick material such as teflon or polyethylene with one side of the layer made of a high-tack silicone or arcylic adhesive to attach the layer to the binding. The exterior non-stick surface of the layer provides a most effective means for preventing snow and ice buildup on the binding plate and includes a means of covering the heads of the ski binding mounting screws.

摘要： A method of manufacturing a transducer assembly having a curved transducer array. The method includes the steps of fabricating a laminated assembly by bonding the following layers together: a layer of electrically conductive, acoustic matching material, a layer of piezoelectric ceramic, a flexible printed circuit board and a layer of acoustic damping material. The acoustic damping material changes from an inflexible state to a flexible state when heated. The laminated assembly is then diced to a depth so that the only undiced portion is a portion of the acoustic damping layer. A core body having a curved front face in the shape of a cylindrical section is fabricated. Then at least the undiced portion of the layer of acoustic damping material is heated into a flexible state. The heated undiced portion of the layer of acoustic damping material is flexed to conform to the curved front face of the core body. Then the flexed undiced portion of the layer of acoustic damping material is bonded to the curved front face of said core body. As a result, the piezoelectric elements are arranged along a curve.

摘要： An ultrasonic transducer having reduced total electrical impedance is constructed by stacking a plurality of piezoelectric transducer element arrays on top of each other. For a given thickness, the electrical impedance of a multilayer stack of piezoelectric transducer element arrays is a function of the number of layers. If the number of layers equals two, then the electrical impedance of the total stack-up of layers is reduced by a factor of one-quarter relative to the electrical impedance of a single layer of equal thickness. This facilitates matching the overall transducer impedance to that of the connecting cable.

摘要： A same transducer includes both piezoelectric and CMUT transducer layers. The semiconductor substrate used for the CMUT is also used as a matching layer. A portion of the semiconductor material is removed and the kerfs or voids are filled to provide the desired density, volume ratio, and/or acoustic impedance. This composite portion operates as a matching layer for the piezoelectric transducer layer.

摘要： A compound lens for focusing ultrasound emitted from an ultrasound probe having an array of piezoelectric transducer elements. The compound lens has an inner lens part with a convex cylindrical front face and a rear face which is acoustically coupled to the front face of the transducer array, and an outer lens part with a concave cylindrical rear face which is acoustically coupled to the convex cylindrical front face of the inner lens part. The inner lens part may be in the form of a conventional silicone rubber focusing lens. The outer lens part is made of an acoustic medium having a higher acoustic velocity and greater durability than silicone rubber, e.g., polymethylpentene, nylon and high-density polyethylene. Also the outer lens part has greater chemical resistance than silicone rubber.

摘要： Backing blocks, transducer arrays and methods are provided for thermal cycle survivability. By decoupling a portion of the backing block from a case used to contain the transducer stack, the greater thermal expansion properties of most backing blocks may be minimized. For example, a rim is formed on the backing block material. The rim is bonded to the case structure while other portions of the backing block remain free of bonding to the case structure. During thermal cycling or other temperature changes, the backing block may be less likely to expand or bulge and crack, delaminate or damage transducer elements or other transducer materials.
