Abstract

A device that is placed between the electrical power source and electrical equipment such that power going to the equipment can be controlled, regulated, and monitored. An individual may request access to use the electrical equipment by means of unique identification. The device is able to compare the user'"'"'s request for authentication via a locally stored list (database) or remotely situated list. The device contains audio and visual indications of the current status of power going to the electrical device. An apparatus is used to prevent a user from disconnecting electrical equipment from the device and reconnecting it directly to the power source. A related method of use is also claimed.

Claims

1. A method for controlling power flow to an electrical device comprising:

(i) providing a power control system that includes;

a first contact for electrical communication with a first plug to a current source;

a second contact for electrical communication with a second plug to the electrical device;

a switch in communication with the first contact and the second contact, the switch movable between an on-condition, where electric current flows through the switch, and an off-condition, where electrical current does not flow through the switch;

a moveable member, moveable between a first position and a second position, said movable member including;

(a) a first portion for causing the switch to move between the on-condition, when the movable member is in the first position, and the off-condition, when the moveable member is in the second position; and

(b) an electronic card reader which takes an individual operator card when properly positioned on said reader to open the switch for a preset amount of time from the off-condition to the on-condition, said reader being in contact with a database for determining whether a holder of that operator card is authorized to have the switch opened from the off-condition to the on-condition; and

a lockable housing for encasing the first plug and the second plug;

(ii) inserting the power control system between the first plug to the current source and the second plug to the electrical device;

(iii) locking an enclosure about the first plug and the second plug; and

(iv) activating the reader to receive individual operator cards and verifying a numerical or biometric identifier from each card before determining whether the switch can be moved from the off-condition to the on-condition.

2. The method of claim 1 wherein the reader further records and keeps track of every operator card that has attempted to access and run the electrical device.

3. The method of claim 1 wherein the reader keeps track of when and for how long every operator card has run the electrical device.

4. The method of claim 1 wherein the reader includes a visual indicator that the operator card is authorized to run the electrically powered device to which it is connected.

5. The method of claim 1 wherein the reader includes an audio indicator that the operator card is authorized to run the electrically powered device to which it is connected.

6. The method of claim 1 wherein the numerical or biometric identifier is selected from the group consisting of:

an RFID signal, a phone (NFC) signal, a PIN identifier, a magnetic strip and a bar code.

7. The method of claim 1 wherein the numerical or biometric identifier is selected from the group consisting of:

a fingerprint, a heart rate, an eye pattern, a vein pattern in an operator'"'"'s hand and facial imaging.

8. The method of claim 1, which further includes an interrupter for moving the switch from the on-condition to the off-condition before an amount of authorized use is about to be exceeded.

9. The method of claim 1 wherein the database is external of the reader.

10. The method of claim 1 wherein the switch is electronic.
