  • Patent number: 5850753
    Abstract: A controllable catch mechanism is installed in the door frame of hotel room to engage both a spring-biased latch and a deadbolt associated with the room door. The position of the deadbolt is sensed or a requirement for privacy is otherwise indicated with a switch within the room. An alphanumeric keyboard external to the room allows entry of access codes. If an authorized guest code is entered, a microprocessor-based controller unlocks the catch mechanism regardless of the privacy requirement. The guest code can be changed by the guest, as desired. If a cleaner enters a universal access code, the controller unlocks the catch mechanism only if the bolt is unlocked or no privacy requirement is indicated. Special override codes are provided that unlock the catch mechanism regardless whether the bolt is locked, permitting security staff to handle emergencies.

  • Patent number: 4858336
    Abstract: A wall-mounted hair dryer appropriate for mounting in bathrooms with limited wall space comprises a housing contain a fan unit, an air flow divider which produces two air flows, and an electric heating unit which heats one of the air flows. A flexible conduit assembly directs the two air flows to a nozzle, and includes an inner conduit which conveys the heated air flow and an outer conduit which conveys the cooler air flow thereby ensuring that the exterior of the conduit assembly remains cool to the user's touch. The air flows are combined within the nozzle to reduce temperature of the discharged air. A frame is hinged to the housing and normally seats in a recess formed in a forward surface of the housing. A two-sided mirror assembly is mounted in a central opening formed in the frame for pivoting movement about a horizontal axis. An electrically-operable lighting unit including appropriate reflectors projects light to opposing sides of the frame thereby illuminating either of the mirror surfaces.
