Fixtures () at a doorway () of a landing () are formed integrally with a door frame (). The fixtures include electronic modules () and energy storage devices (). Power may be supplied by a generator () rotated by a pinion () in response to a rack () on a hoistway door (), or by electrical contacts () disposed on the hoistway side of the door frame which touch contacts () on an elevator car door () when the door is open, thereby receiving power over a line () from the elevator car; or power may be provided by an inductive coupler (). The fixtures () may be within the profile of the door frame (), or extend outwardly from the profile of the door frame ().

Wireless elevator hall fixtures integral with hall door frame

A system and method for monitoring a location having at least one sensor for sensing a change in at least one condition using voice tags to announce alarms. The system includes a registration process where a voice recorder and a digital conversion unit form digital voice tags from recorded speech representing the type and location of sensors. The voice tag is sent as part of an alarm message or pre-stored in a control panel for later retrieval such that the type and location of an alarm is reproduced vocally at the time of the alarm. The registration process may be completed with a registration module which may be a keypad or the voice recorder may be included in the sensors. Additional features include sensor location change notification to ensure the stored voice tag represents the current location of the sensor.

Voice recorder based position registration

Fixtures () at a doorway of a landing are formed integrally with a frame (). Power is provided by an inductive coupler () having a core () and primary (). The core is thin ferrite and extend significantly beyond the coils in the plane the coils are wound, to provide en extremely low resistance path for the efficient transfer of AC power.

Inductively coupled power, useful for wireless elevator hall fixtures

An elevator system has on each floor hall call buttons that are inter-connected with piconet modules (), such as modules conforming to BLUETOOTH&#x2122; specifications; similar piconet modules () may be associated with hall fixtures such as lanterns and gongs; similar piconet modules () may be associated with hoistway doors, on each floor, so as to form a wireless communication system with a similar piconet module () at the controller (); and a piconet module () may be associated with the car operating panel. A module () may be interconnected with the car door lock switch; a module () may be interconnected with a safety switch; modules () and () may be interconnected with lower and upper limit switches; and a module () may be interconnected with an overspeed detector, so as to form a safety chain. A prospective passenger () may carry a portable device with a piconet module () to request elevator service and receive acknowledgment, and maintenance personnel () may use a personal ditigal assistant having a piconet module () therein to acquire current and historical information about the elevator and to issue executable commands to the elevator system.

Elevator wireless communication infrastructure using piconet modules

An elevator safety chain includes a plurality of passive radio frequency identification devices (RFIDs) (--and), which are associated, respectively, with hoistway door locks, upper hoistway limits, lower hoistway limits, overspeed detection, car door lock, emergency stop switch, and inspection switch. RFlDs may be associated with car the call buttons () and/or hall call buttons (). The RFIDs may have a switch () in the frequency-determining circuitry () which defeats the RFID's ability to respond, or a switch () which alters the responding frequency. The RFIDs may sense safe or unsafe conditions, or call requests, by either the presence of absence, or vice versa, of adjacent magnetic reluctance ().
