Abstract: The magnetic anti-tampering system of the magnetically enhanced key and lock system provides a mechanical and magnetic security system. It utilizes a modified paracentric key and a locking assembly affixed to a component inside of a paracentric lock. The magnetically enhanced key and lock system increases the security of a pair centric lock by defeating the unauthorized operation of pair centric locks by unauthorized users, such as inmates, who have fabricated copies of the authentic, paracentric keys. Paracentric locks and keys are the most common type of locks used in jails, state prisons, and detention facilities. The locking system requires that both the teeth of the key and the magnetic pairs of the key and locking dog combine to open the lock.

Abstract: The present invention is directed to a surgical otoscope for examining and operating upon the external ear canal and tympanum. The surgical otoscope comprises an optical diagnostic instrument and an adapter member attached thereto. An image conveyer and a light transmitter are located within the optical-diagnostic instrument and extend therefrom and into the adapter member. The adapter member includes extendable and retractable surgical instrumentation and a suction tube. The combination of optical diagnostic and surgical instrumentation in the same device a enables a physician to simultaneously examine and operate upon the external ear canal and tympanum. Accordingly, the physician may selectively use the instruments while viewing the areas to be examined or operated upon through the same device.
