US Patent:

6396199, May 28, 2002

Filed:

Jun 30, 2000

Appl. No.:

09/608212

Inventors:

Stephen Douglas - Cary NC
Shinji Ogawa - Norrisville NC

Assignee:

Prosonic Co., Ltd. - Kyongbuk

International Classification:

H01L 4108

US Classification:

310335, 310334

Abstract:

A double-sided flexible circuit is used to provide interconnection to a piezoelectric ultrasonic transducer array. The ultrasonic crystal is covered with first and second electrode layers having an insulation gap provided therebetween. The flexible circuit material is then bonded to the first and second electrode layers so that one side of the double sided flexible circuit makes contact to one set of transducer electrodes and the other side of the flexible circuit makes contact to the second set of transducer electrodes. The ultrasonic transducer desirably includes a concave acoustic lens having an acoustic velocity greater than water.

International Classification:

A63B 21/012

US Classification:

482114, 482904

Abstract:

An exercise apparatus includes a handle bar and a resistance assembly, coupled to the handle bar. The resistance assembly includes a housing having first and second opposed parts, and permitting movement of the handle bar about a rotational axis upon applying force to the handle bar. A resistance mechanism resists movement of the handle bar about the rotational axis. A screw, mounted lengthwise along the rotational axis, and engaging a threaded receptacle, adjustably compresses the spacing between the housing parts and modifies resistance to movement of the handle bar. One of the screw and the receptacle is coupled to an adjustment knob setting a user-defined resistance. A clamp, coupled to the housing, removably attaches the exterior of the first housing part to a member. A user grasps the handle bar and moves it by applying force corresponding to the resistance setting. The clamp can be utilized without operating the knob.

H04R 31/00

Abstract:

Disclosed is a 2D Matrix Array Backing Interconnect Assembly that provides a structure that enables simple construction of complex wring for an ultrasonic transducer array of desired dimension. A backing interconnect assembly can be produced by forming a plurality of high density interconnect printed circuit boards, with layers each having a respective array of metal traces, wherein the metal traces are internally connected one-to-one to electrically conductive pads. An end of the metal traces are exposed at a surface to form respective conductive elements. High density interconnect printed circuit boards can be attached to a flexible printed circuit having contact pads that correspond to conductive pads of the printed circuit boards to form interconnect modules. The interconnect modules can be attached to form a backing interconnect assembly. The backing interconnect assembly with exposed conductive elements provides complex wiring interconnect for manufacture of small sized 2D ultrasonic transducer arrays.
