Abstract: An ultrasonic surgical device is disclosed including a surgical tool including a proximal transducer mounting portion defining a surface, a distal end effector end, and a waveguide disposed therebetween, the waveguide extending along a longitudinal axis. The ultrasonic surgical device further includes a transducer is in mechanical communication with the surface of the transducer mounting portion. The transducer is configured to operate in a D31 mode with respect to the longitudinal axis of the waveguide. Upon activation by an electrical signal having a predetermined frequency component, the transducer is configured to induce a standing wave in the surgical tool to cause the end effector to vibrate, the standing wave having a wavelength proportional to the predetermined frequency component of the electrical signal.

Abstract: A device for stabilizing a hand-held motion picture or videotape camera having a member for supporting the photographer's arm and a curved support at its lower end, which rests upon the photographer's thigh. The device is secured around the photographer's body by an adjustable strap. A U-shaped armrest is provided to hold the photographer's elbow in position on top of the member. In its preferred form, an adjustable clip may be attached to the lower part of the member to engage the belt of the photographer for additional stability.
