Abstract: A dental flossing apparatus, comprising a length of dental floss having two ends and two floss holders. One floss holder is attached to each end of the dental floss. Each floss holder comprises a flat piece of plastic having an edge with a continuous groove therein. The groove allows dental floss to be wrapped around the floss holder. Each floss holder is molded around one end of the dental floss, forming a very secure bond between the floss and the holder.

Abstract: A novel computer-controlled video microscopy system, features a rotatable objective lens turret. The lens turret is a rotatable cylindrical drum having an open end and closed end. A plurality of light-transmitting objective lenses are evenly spaced about the side wall of the cylindrical drum. The objective lenses are each directed perpendicularly to the axis of rotation of the cylindrical drum. A computer is used to select a desired objective lens and signal a motor to rotate the cylindrical drum about its axis of rotation, so as to move the selected objective lens into the path of an approaching light beam. When the light beam enters the drum through the objective lens, a prism or mirror inside the cylindrical drum bends the light beam at a right angle and directs it out of the drum through its open end. An image carried by the light beam is then focused onto the imaging plane of a video camera.
