Abstract: A surgical apparatus for removing deposits from an interior of a vessel comprising a rotatable shaft and a rotatable tip mounted to the rotatable shaft which is rotatable about its longitudinal axis upon rotation of the shaft to remove deposits from the interior of the vessel. The tip has a distal portion, a proximal portion and an intermediate portion between the distal and proximal portions. The intermediate portion is defined by a plurality of transverse cross-sectional areas, wherein each transverse cross-sectional area defines first and second axes substantially perpendicular to each other to define a width dimension along a first axis and a height dimension along the second axis. The height dimension is greater than the width dimension.

Abstract: Display cards are provided for displaying sunglass attachments for eyeglasses, specifically inexpensively produced mountings to display a drop-on sunglass attachment from a display rod that allow a prospective purchaser to sample the drop-on sunglass attachment prior to purchasing without removal of the drop-on sunglass attachment from the display card. An upper and lower substantially rectangular, planar members slightly greater in width than a drop-on sunglass attachment are provided, including a horizontal slot located in the upper member for receiving a molded hook in the top of the drop-on sunglass attachment. The lower member has essentially equal dimensions as the upper member, and hingedly connects to the upper member through a thin segment only as wide as the nosepiece of the drop-on sunglass attachment.

Abstract: An improved capacitive sensor for detecting the presence of objects in a sensing region. The sensor is a multilayer structure with alternating layer of condutive and insulating materials. The sensor structure has three electrodes: a touch plate, a guard layer, a ground plane, each of which are separated from each other by insulating layers. The sensor is operated by detection electronic circuitry which function in a either a self excited mode or an externally excited mode. This sensor is capable of detecting objects in a sensing region several feet away from the sensing surface and is particularly suitable for automobile applications, such as detecting potentially jamming objects in power (auto-closing) windows, doors, and the like.

Abstract: A transducer and tone generator embodying the same and method of assembling the transducer components with the use of an assembly fixture. The transducer components include a rigid annular structure, a pole piece, an electromagnetic coil assembly, and a diaphragm.
