  • Patent number: 10581214
    Abstract: A lockout system for a laser device of a type having a laser emitter operable to emit a laser beam at a plurality of intensity levels includes a lockout switch operable to be placed in either a first state or a second state, wherein the laser device is configured to prevent actuation of the laser emitter at an intensity level above a preselected threshold intensity level when the lockout switch is in the first state and to permit actuation of the laser emitter at an intensity level above the preselected threshold intensity level when the lockout switch is in the second state. A lockout key operable to transition the lockout switch between the first state and the second state. In a further aspect, a laser sight device incorporating the lockout system herein is provided.

  • Publication number: 20070092455
    Abstract: Novel aqueous slurries capable of removing calculus, plaque or stains, adherent to tooth surfaces of a warm-blooded animal, when used in methods that are self-practicable by an individual human or practicable by an individual human on another warm-blooded animal, combine finely-divided charcoal; water; and alcohol, ammonia or hydrogen peroxide to form the slurries. Also disclosed are self-practicable methods that utilize the disclosed aqueous slurries by applying to, and contacting affected tooth surfaces with, the same, then removing the treated calculus, plaque or stains by means of devices and techniques that are safe to use according to the methods. Further, kits are disclosed that comprise the disclosed aqueous slurries, as well as apparatus, devices and tools for effectively using the same for the above purposes.

  • Publication number: 20050147569
    Abstract: Aqueous slurries, capable of cleaning the tongue and throat of a patient when used by an individual for personal hygiene or used on another warm-blooded animal, combine finely-divided charcoal, water, and a biocide. Also disclosed are methods for cleaning areas of the tongue and throat in need thereof. The methods use the disclosed aqueous slurries, as well as apparatus, devices, and tools for contacting the areas to be cleaned with the aqueous slurry and for removing unwanted material from the areas cleaned, as well as from the oral cavity, generally. The disclosed methods can be safely practiced for personal oral hygiene, or on another. Further, kits are disclosed that are useful for such cleaning in providing a contained quantity of a disclosed aqueous slurry or contained quantities of the components thereof, as well as apparatus, devices and tools for effectively preparing and using the same for the above purposes.

  • Patent number: 6239874
    Abstract: An orientation detector arrangement is adapted to detect the orientation of a first component relative to a second component, preferably during endoscopic surgery. The first component is a transmitter which may be worn on a surgeon's head. The transmitter is adapted to transmit a plurality of unique identifiable signals along mutually diverging beams. The second component is a detector which is adapted to distinguish between the individual signals transmitted by the transmitter. The detector is connected by a control circuit to an endoscopic camera which is, in turn, connected to provide an image on a display screen. The detector and the associated control circuit are able to control movement of the endoscopic camera in response to movement of the surgeon's head.
