Abstract: The present optical image viewing fiberoptic otoscope electromagnetically passive. A body portion is connectable to a light source and has mounted to it a fiberoptic cable and an optical viewer. The fiberoptic cable is thin and flexible, and contains separate light and image transmission paths. Its distal end is adapted for emitting and receiving light. The body includes a light source connection for interfacing an external light source. An optical-type image viewer attached to the body is in light communication with the image path for displaying a received image for viewing by a user. One or more tools are mountable to the otoscope body or fiberoptic cable for performing an operation at the distal end of the fiberoptic cable, e.g., removal of a material from the site. Optionally, the otoscope body may be mounted to a headband via an articulated support arm.

Abstract: A tensioning device for providing tension to a length of running cable or line (e.g., wire rope) as it is being wound onto a drum. The tensioning device has a tubular housing in two longitudinal halves, the tubular housing halves hingeably joined along one set of adjacent edges by a hinge means and closeable along the second set of adjacent edges by a clamp means. A removable inner sleeve for receiving and compressing stock in two longitudinal halves, each sleeve half closely received in and lines the interior surface of each tubular housing half. The inner sleeve contains an axial bore equally along its length between the two sleeve halves. The combination of the hinge and clamp means closes the housing halves, compressing the inner sleeves. Anchor rings are mounted on the housing for fixing the device against movement.
