Abstract

A facility access system includes a system microprocessor and input and output subsystems. The input subsystem can include switching devices connected in a parallel configuration for actuating the system microprocessor in a sequencing mode of operation. Input devices are also disclosed which produce input signals corresponding to particular memory storage locations for accessing directional and other information in a look-up mode of operation. The directional and other information is output to text display, graphical display and audio output devices. A user'"'"'s computer can be linked to the system microprocessor for downloading information therefrom. An emergency subsystem provides emergency exit information, dials out to summon assistance and includes a backup power source.

Claims

1. A facility access system, which comprises:

a) a system data processor with an input and an output;

b) an input subsystem connected to said system processor input;

c) an output subsystem connected to said system processor output;

d) data storage accessible by said output subsystem for providing output data associated with the facility to the output subsystem;

e) said input subsystem including a hardwired switching device and a wireless switching device;

whereby a user with a disability could operate at least one of said switching devices; and

f) a plurality of software subroutines selected by the user and accessible by said system processor and each outputting data corresponding to a respective destination associated with the facility to said output subsystem;

said data including directions to said destination; and

g) an external device associated with the facility and activated by the output subsystem in response to a user input to the input subsystem.

2. The facility access system according to claim 1 wherein said system processor includes said data storage and said system processor is adapted to write directional data associated with the facility to said data storage.

3. The facility access system according to claim 1 wherein said data storage is connected to said system processor and said system processor is adapted to write directional data associated with the facility to the data storage.

4. The facility access system according to claim 1 wherein said switching device comprises a contact switch.

5. The facility access system according to claim 1 wherein said switching device comprises an infrared-actuated switching circuit including an infrared receiver connected to said system data processor and a remote infrared transmitter.

6. The facility access system according to claim 1 wherein said switching device includes a voice-actuated switching circuit connected to said system data processor.

7. The facility access system according to claim 1 wherein said output subsystem includes an LCD display for displaying textual messages comprising said directions to destinations within the facility.

8. The facility access system according to claim 1 wherein said output subsystem includes:

a) a graphical representation of the facility; and

b) a plurality of indicators mounted on said graphical representation and corresponding to travel paths in the facility to predetermined destinations therein.

9. The facility access system according to claim 8, which includes:

a) said output indicators comprising LED'"'"'s; and

b) said system processor selectively and sequentially activating said LED'"'"'s along a plurality of predetermined travel paths.

10. The facility access system according to claim 1 wherein said output subsystem includes:

a) an audio circuit including a speaker for playing prerecorded, stored messages comprising directions to predetermined destinations in the facility.

11. The facility access system according to claim 1 wherein said output subsystem includes:

a) said facility having an electrical power system;

b) a signal transmitter connected to said system processor and to said facility electrical power system;

c) a signal receiver connected to said facility electrical power system and adapted to receive signals from said signal transmitter; and

d) said signal receiver including a switching circuit adapted to activate an electrical device in response to receiving a signal from said signal transmitter.
