Abstract: An electro-mechanical transducer, which provides radial amplified multiple piston motion is formed from attached multiple lever arms and multiple electro-mechanical drivers. The piston motion is amplified by lever arms, which are attached to electro-mechanical drivers, such as piezoelectric or magnetostrictive drivers, which oscillate in a radial direction in unison with the applied voltage. A minimum of three pistons, three lever arms (or shells) and three drivers may be used. A preferred embodiment, uses four pistons, four lever arms (or shells) and four drivers. As a result of both the magnified motion of the lever arms (or shells) and the large acoustic radiating area of the multiple pistons, the transducer provides a means for a high-source level from a compact low-frequency broadband transducer.

The pad assembly includes a resilient pad having at least one ground engageable work surface and a holder for the resilient pad. A first pivot is provided for supporting the pair of plate members from a stabilizer base; and a second pivot is provided that is substantially transverse to the first pivot for supporting the pad assembly from the plate members.

Abstract: A step-in binding for receiving a ski boot and preferably for telemark skiing. The binding includes a base constructed and arranged to be secured to the ski and a pair of boot support members pivotally supported from a front side of the base, and disposed laterally on either side of the base. The lateral side members may be tapered inwardly toward the front so as to receive and guide the ski boot as it is to be engaged. The pair of boot support members are biased to a boot receiving position and further having a locked position that is assumed once the boot is received, engages the pair of boot support members, and is cantilevered downwardly into the locked position.

Abstract: A stabilizer pad apparatus including a metal frame for attachment to a stabilizer arm and a resilient pad supported in the pocket of the frame and including a clamping plate to hold the resilient pad in the pocket. The metal frame has sidewalls forming a pocket for receiving the resilient pad. At least one elongated securing member extends through the resilient pad having one end secured at one sidewall of the frame and having another head end disposed at the other sidewall of the frame. The head end has a non-circular shape that is accommodated in a like shaped aperture in the other sidewall.

Abstract: An endoscopic or laparoscopic instrument includes a distal tool, a rigid or flexible elongated shaft that supports the distal tool, and a proximal handle or control member, where the tool and the handle are coupled to the respective distal and proximal ends of the elongated shaft via bendable motion members. The tool and the tool motion member are coupled to the handle and the handle motion member via cables and a push rod in such a way that the movement of the handle with respect to the elongated shaft in any direction is replicated by the tool at the distal end of the shaft. The magnitude of the tool motion with respect to the handle motion may be scaled depending on the size of the handle motion member with respect to that of the tool motion member.

Abstract: A stabilizer for a heavy equipment machine includes a pair of resilient pad assemblies each having opposed surfaces either of which can be positioned as a ground engaging surface, and a support pin that extends in opposed directions from a stabilizer arm of the machine. Each of the resilient pad assemblies has a respective passage for receiving the support pin for enabling rotational support of the resilient pad assemblies from the support pin. The support of the resilient pad assemblies enables the positioning of either of the opposed surfaces as the ground engaging surface.

Abstract: Pad assemblies configured to be used in conjunction with stabilizer pads mounted onto stabilizer arms used to stabilize earth moving and other construction equipment. The pad assemblies are formed from either a resilient laminate or solid piece mounted onto a bracket which in turn is mounted onto the stabilizer pad. The pad assemble includes a support bracket, and a pad having a base captured in the support bracket and formed of a resilient material that defines a base surface. The pad is being retained by said support bracket and has a ground engaging surface opposite to the base surface and defined as an uneven ground engaging surface formed of separate ground engaging pad surface areas that terminate at different distances from the base surface.

Abstract: An electro-mechanical transducer, which provides beam patterns synthesized from the vibration modes of the transducer. A preferred form of the transducer is a short piezoelectric tube or ring with separate electrodes spaced around the ring for specific excitation of the monopole, dipole and quadrupole modes of vibration. Operation of the transducer in the region between the dipole and quadrupole modes yields a system with a nearly constant beam pattern and transmitting response. The arrangement allows a simple directional steered beam pattern from a single transducer.

A pivot mechanism incouples a handle at the outer ends of the arms and includes a spring for biasing the arms to a position wherein the cutter blade is closed. The pivot mechanism interacts with the arms to bias the arms to a position wherein the cutter blade is closed while enabling the pivoting of the arms to open the cutter blade to receive a wire or the like for cutting.

Abstract: Pad assemblies configured to be used in conjunction with stabilizer pads mounted onto stabilizer arms used to stabilize earth moving and other construction equipment. The pad assemblies are formed from a resilient laminate mounted onto a bracket which in turn is mounted onto the stabilizer pad. In one embodiment, the bracket includes side flaps for capturing the laminate therebetween. Preferably, the bracket is formed of a single piece of metal. A bolt, pin, rivet or the like is used to secure the laminate to the side flaps. Methods of forming the pad assemblies are also disclosed. In particular, a reverse camber is provided to the top surface of the bracket so that when the side flaps are bent downwardly, the top surface does not bow upwardly. Reinforcing ribs are also provided for the same purpose. Bowing is also minimized by facilitating the bending operation by cutting out material along the fold lines, to decrease the resistance to bending of the material.
