    摘要: A method of producing an acoustically absorbing anisotropic backing structure for an ultrasound transceiver is disclosed. Laser machining of a substrate of acoustically absorbent electrically resistive material produces a set of vias and indented pad seats. The machined substrate is plated with an electrically conductive material. Excess electrically conductive material is removed from the substrate to leave an electrically conductive material plating on the indented pad seats and the vias to form conductive pads and plated vias on the substrate.

    摘要: An improved ultrasound transceiver array for permitting improved imaging is taught. The array may be either a two dimensional array for volumetric imaging or a one dimensional array of elements shaped to permit a more precise beam focus for finer resolution imaging. An Nd:YAG laser is used to machine a workpiece from both ends to produce kerfs which taper inwardly from the transceiving side of the array thereby permitting a stronger ultrasound signal and clearer imaging.

    摘要: A bodily implanted charge injection assembly for effecting a voltage difference between a specific body location and surrounding tissue. This assembly comprises a charge injection device that includes a first electrode assembly and a housing defining an interior space substantially enclosing the first electrode assembly and further defining a first opening placed near the specific location. The housing is filled with electrolytic solution. Also, a second electrode assembly is placed in contact with both the electrolytic fluid and the surrounding tissue. In addition, a physical gate assembly is adapted to selectively and controllably occlude the interior space so that either the first opening or the second electrode assembly may be occluded from the first electrode assembly. The physical gate assembly is controlled to drive current through the opening and alternately to refresh the first electrode assembly with current from the second electrode assembly.

    摘要: A method for the real-time transformation of an electrical signal representative of a sound wave that includes the steps of providing an electrical signal representative of a sound wave, transforming that signal to an analytic representation, and passing said electrical signal, in parallel, through a number of bandpass filters to create a set of time domain real and imaginary band limited signals. Next, a stream of instantaneous phase angle and magnitude values for each of said set of time domain real and imaginary band limited signals is computed. Thirdly, a stream of electrical pulses or other digital representation of the phase, instantaneous frequency, and magnitude information is computed for delivery to a cochlear implant or transmission for decoding and synthesis of the original sound.

    摘要: Connectors for attachment to cables including a large number of very small flexible conductors (26) or coaxial conductor pairs (74). In a first embodiment very small contacts (36) are arrayed on a flat mating surface (28) of the connector body (22). Contacts (36) are raised slightly above the mating surface by plating conductive metal to form raised bumps (42) on one of a pair of connectors (14, 16). Insulated individual conductors (26) are placed through apertures (48) defined in a substrate acting as a template, and are fastened in place by potting material (50) before shaping the mating surface (28) of the connector body (22) or (24) is shaped. Pin and socket combinations (30, 32) are used to align mating connectors with each other. In other connectors (176, 178) contact bases (198, 200) to be plated may be defined precisely by photoresist lithography on a cover layer (192) attached to the template substrate (180, 182), and an elastomeric layer (190 ) may be provided between the cover layer and the template substrate. In other connectors (90, 146, 240, 460) shields of coaxial conductor pairs and shields of flex circuits are connected electrically to conductive common layers (98, 154, 246, 474) on the rear side of the substrate. In one connector (370) flex circuit conductor traces are exposed on a mating face (394) as contacts (396, 398).
