Abstract

The invention is a data interruption device which is comprised of an input port, an output port and a connection therebetween. The data interruption device provides for two states, one where the connection between the input port and output port is open, and the other where the connection is closed. A switch provides for the transition between the two states. The device also includes an external mechanism, preferably a push button, to activate the switch. The switch may also be controlled from a computer, if desired.

Claims

1. A device comprising an input port, an output port and a switch wherein said switch is operative to open and close the connection between said input port and said output port and wherein one of said input port and said output port is connected to a computer and the other of said input port and said output port is connected to the Internet.

2. The device according to claim 1, wherein one of said input port and said output port is connected to a computer and the other of said input port and said output port is connected to a Local Area Network (LAN).

3. The device according to claim 1, wherein said switch is operated by a push button.

4. The device according to claim 1, wherein said switch can be operated from said computer.

5. The device according to claim 1, including a display operative to indicate the status of said connection.

6. The device according to claim 1, including a timing mechanism operative to automatically activate said switch and close said connection after a set time period of inactivity in said connection.

7. The device according to claim 6, wherein said device includes one or more DIP switches operative to set and modify said time periods of said timing mechanism.

8. The device according to claim 6, wherein said time periods of said timing mechanism are set and modified by software on said computer.

9. The device according to claim 1, including a security system operative to control access to said device.

10. The device according to claim 9, wherein said security system includes a fingerprint scanning device.

11. A method of interrupting a connection between an input port and an output port, said method comprising:

a) inserting a switch into said connection;

b) monitoring data flow activity within said connection;

c) activating a timer when said connection becomes inactive;

d) closing said switch when said timer reaches a preset value, thereby closing said connection; and

e) deactivating said timer when said connection becomes active and said timer has not reached said preset value;

wherein one of said input port and said output port is connected to a computer and the other of said input port and said output port is connected to the Internet.

12. The method according to claim 11, additionally including:

a) activating a second timer when said connection is closed;

b) locking said connection in a closed state, such that said switch cannot be opened by a signal from said computer, when said second timer reaches a second preset value; and

c) opening said connection when a signal is received from said computer and said second timer has not reached said second preset value.

13. The method according to claim 12, wherein said switch can be opened or closed by an external mechanism operating independently of said timer and said second timer.

14. The method according to claim 11, wherein one of said input port and said output port is connected to a computer and the other of said input port or said output port is connected to a Local Area Network (LAN).
