A telephone communication system having a locator and a scheduling facility includes: a PBX connected to telephones for facilitating communication between users; a scheduling unit for storing user schedule information for the users; and a locator system for providing location information. The locator system includes portable units associated with respective users which transmits an identification signal for identifying the user. The portable units include portable computing devices for interactively processing scheduling information with the scheduling unit. Transceivers receive the unit information from the portable units for forwarding the unit information to the PBX to determine location information of the users. The PBX activates telephone functions for use in conjunction with the location information for communicating with a called user, and the PBX accesses the user schedule information of a first user, for retrieving a specific location associated with the first user for generating a schedule notification message for communication to the first user at the specific location thereof.

A system for providing a personal location, access control and asset tracking service using an in-building telephone network is disclosed. In a first embodiment, users of ID badges containing an RF transmitter can be located across the telephone network for receiving incoming calls. Receiver units in or near telephone sets instruct the system of the identity of the user located near the telephone set. In another embodiment, access to a building or rooms therein is controlled according to the identity of the ID badge wearer. Similar receiver units locating at building and room entrances receive the RF transmission from the ID badge to allow or deny access to the rooms or building. In a third embodiment, ID tags placed on material assets permit the system user to monitor the movement and location of specific material assets associated with that ID tag. The ID tag also contains an RF transmitter which is used to transmit an RF burst to receiver units located across the telephone network.

Video door entry system 5 which comprises an internal unit 10, in turn comprising a video screen 12 and intended to be positioned inside premises, and an external unit 20 intended to be positioned at an access barrier of said premises. The external unit 20 of said video door entry system 5 comprises a camera 22 suitable for acquiring images of the area situated in the proximity of the external unit 20 and for sending them to the video screen 12 of the internal unit 10 for display thereof. Said external unit 20 also comprises a control unit 25 and an operating unit 27 suitable for performing opening of said access barrier following a command of the internal unit 10. The video door entry system 5 is characterized in that said camera 22 is able to recognize and acquire a two-dimensional bar code 32 shown to it. Furthermore, said video door entry system 5 comprises decoding means 26 suitable for decoding said two-dimensional bar code 32 in order to extract the information contained in it and execute operating commands according to said extracted information.

摘要:
Zur Beschleunigung der Anschaltung der Geräte (separater Lautsprecher, Lautsprecher des Endgerätes) zum Zwecke einer Durchsage wird aufgrund einer einzugebenden gruppenindividuellen Kennzahl (KZ) zunächst an eine begrenzte maximale Anzahl von zugehörigen Geräten durch die Rechnersteuerung (Ast) die Anschalteaufforderung gleichzeitig übermittelt. Es wird ein auf diese Anzahl einzustellender Zähler (PZ) aufgrund einer jeden eintreffenden Quittungsinformation (ZRS) zurückgestellt. Es werden dann jeweils solange weitere Anschalteanforderungen (VA) an die Geräte ausgesendet, bis diese maximal vorgegebene Anzahl von Aufrufen erneut erreicht ist. Mit dem Quittungszeichen des letzten Gerätes (KE-D-Bg) der Gruppe (GR) wird durch einen entsprechenden Hörton (TSg) die Bedienperson darüber informiert, daß die wirksame Anschaltung aller freien Geräte der Gruppe erfolgt ist.
摘要:
Es wird ein Verfahren zum drahtlosen Übertragen eines Anrufsignals vorgeschlagen. Das von einem Signalgebar abgegebene Anrufsignal wird mit einem Funksender (14) ausgekoppelt. Das Anrufsignal veranlaßt einen Datentelegrammgeber (16)'des Funksenders zur Abgabe eines bestimmten Datentelegramms, das der Funksender als Modulation eines Trägers mit einer Frequenz unter 10 kHx ausstrahlt. Ein tragbarer Rufempfänger (23) empfängt den modulierten Träger, demoduliert ihn und führt das durch die Demodulation erhaltene Datentelegramm einem Äuswerter (25) zu, der nur bei Übereinstimmung des empfangegen Datentelegramms mit einem vorgegebenen, dem zugehörigen Funksender entsprechenden Datentelegramm einen Tongenerator (26) einschaltet. Dieser steuert einen Lautsprecher (27) mit einer bestimmten Tonfrequenz an, die den Benutzer auf das Vorliegen eines Anrufs aufmerksam macht.
