Abstract
A modular door access control system incorporates a plurality of wireless door modules. Access request signals are transmitted to a remote access control unit. The control unit transmits access authorizing control signals to a respective one of the modules. A newly installed module, in a selected mode, enters into communication with the unit. The unit in turn transmits an identifier to the module for use in identifying itself to the unit subsequently in response to a received access request.
Claims61
A module for granting authorization comprising:
- a housing;
- an enabling member, carried by the housing, wherein the member has first and second states;
- a control circuit carried by the housing;
- an access request receiving device, coupled to the circuit, for providing an electrical signal indicative of an access request;
- a transceiver, coupled to the circuit for wirelessly supplying access requesting identification signals to a remote authorization unit and, for receiving access authorizing signals from the remote unit;
- and
- a self-contained power supply carried by the housing for energizing at least the circuit and the transceiver.
4 more elements
A device for enabling a requester to obtain a requested result comprising:
- an input device for making a request;
- a control unit coupled to the input device;
- a transceiver coupled to the control unit includes circuitry for transmitting a request identifying message and a device identifier to a remote authorization unit wherein the device identifier had previously been assigned by and received from the remote authorizing unit.
A system for enabling access comprising:
- a plurality of distributable authorizing modules;
- and
- an authorization control unit wherein each of the modules and the unit are temporarily in communication in an address assigning mode wherein a unit assigned address is supplied by the unit to the respective module for storage therein.
An access authorizing system comprising:
- a plurality of authorizing modules;
- an access authorizing unit wherein the unit includes circuitry for responding to a transient identifying link initiated by a selected member of the plurality and for transferring an identifier thereto for storage therein.
An access control system comprising:
- a plurality of access granting modules wherein the members of the plurality each include;
- an input device for receiving access requesting identification information,
- a control circuit coupled to the input device,
- a wireless transceiver coupled to the control circuit,
- an access permitting element, coupled to the control circuit having at least first and second states;
- and
- an access determining unit, displaced from at least some of the modules, wherein the unit includes at least one wireless transceiver and circuits, responsive to a request from a respective module, for assigning an identifier thereto.
4 more elements
A device comprising:
- a housing;
- an enabling element, carried by the housing, wherein the member has first and second states;
- a control circuit, coupled to the element and carried by the housing wherein the control circuit includes a device identifier previously received from a remote authorizing unit;
- at least one input device, coupled to the control circuit, wherein the input device is selected from a class which includes a card reader, a keypad, a voice detector, a palm scanner and a finger print scanner wherein the input device in response to a received request, couples an electrical signal indicative of that request to the control circuit;
- and
- a wireless transceiver, coupled to the control circuit, for wirelessly transmitting a request signal and the previously received device identifier to the remote authorizing unit, and, for receiving an authorizing signal from that unit.
3 more elements
An enablement system comprising:
- an authorizing unit which includes a list of linked devices wherein a device that has been linked to the unit, by receipt of a linking indicator, receives an enabling command therefrom wherein the authorizing unit includes a transceiver for wireless communication with at least one device;
- at least one device having a transceiver for wireless communication with the authorizing unit;
- a circuit for storage of a linking indicator received wirelessly from the authorizing unit;
- a control circuit coupled to the transceiver and to the circuit for storage;
- and at least one output line from the control circuit for providing at least a part of an authorizing signal wherein the control circuit, subsequent to an authorization requesting transmission of at least its linking indicator to the authorizing unit and a responsive enabling command therefrom, generates the at least a part of the authorizing signal on the at least one output line.
2 more elements
An authorization method comprising:
- placing a selected authorization module into an identifier requesting state;
- transmitting, wirelessly, an identifier request to a displaced authorization control device;
- generating an identifier at the control device in response to a received identifier request;
- transmitting, wirelessly, the identifier to the authorization module;
- storing the received identifier at the module requesting same;
- placing the selected module into another state;
- receiving, at the selected module, a locally generated access request;
- and
- transmitting at least the stored identifier and the access request to the authorization control device.
