## Abstract

A safety system includes an electromagnet positioned in an area. A power controller is coupled to the electromagnet to supply power to the electromagnet in accordance with an event. A trigger mechanism configured to trigger the event when the area is traversed by a person with a weapon such that upon activation of the electromagnet a magnetic force is generated capable of attracting the weapon to make continued use difficult or impossible within the area.

## Claims

### Claim 1

A safety system, comprising;
an electromagnet positioned in an area; and
a trigger mechanism configured to be triggered when the area is traversed by a person with a weapon, such that, upon activation of the electromagnet, a magnetic force is generated capable of attracting materials with magnetic properties to make continued use of the weapon difficult or impossible within the area.

### Claim 2 (depends on 1)

The safety system as recited in claim 1, wherein the trigger mechanism is triggered automatically in accordance with a detector, which detects a presence of the weapon in the area.

### Claim 3 (depends on 1)

The safety system as recited in claim 1, wherein the trigger mechanism is triggered manually using a switch or button activated by a person.

### Claim 4 (depends on 1)

The safety system as recited in claim 1, wherein the electromagnet includes an array of electromagnets positioned about the area.

### Claim 5 (depends on 1)

The safety system as recited in claim 1, wherein the electromagnet is positioned within a wall, floor or ceiling in the area.

### Claim 6 (depends on 1)

The safety system as recited in claim 1, wherein the electromagnet is configured to move to increase a likelihood of attracting the weapon.

### Claim 7 (depends on 1)

The safety system as recited in claim 1, further comprising a grate or door disposed over the electromagnet and configured to permit the weapon to pass through the grate or door when attracted to the electromagnet to prevent access to the weapon.

### Claim 8 (depends on 1)

The safety system as recited in claim 1, wherein the electromagnet is recessed below a surface of a partition such that a captured weapon cannot be fired without hitting the partition.

### Claim 9 (depends on 1)

The safety system as recited in claim 1, further comprising an identification system configured to receive feedback from one or more sensors in the area to determine whether an unauthorized weapon has entered the area and to trigger activation of the electromagnet.

### Claim 10 (depends on 9)

The safety system as recited in claim 9, wherein the one or more sensors includes one or more of a camera and/or a metal detector to detect a presence of the weapon in the area.

### Claim 11 (depends on 9)

The safety system as recited in claim 9, wherein the identification system includes one or more of face recognition, weapon recognition and/or identifier recognition to determine whether the weapon is authorized.

### Claim 12 (depends on 9)

The safety system as recited in claim 9, wherein the identification system includes a score or evaluation to determine risk potential for activating the electromagnet.

### Claim 13

A method for disarming an individual, comprising:
monitoring an area to detect an individual carrying a weapon; and
generating magnetic force in an electromagnet to attract the weapon to make continued use of the weapon difficult or impossible within the area.

### Claim 14 (depends on 13)

The method as recited in claim 13, wherein a trigger mechanism that triggers the electromagnet is triggered automatically in accordance with a detector, which detects a presence of the weapon in the area.

### Claim 15 (depends on 13)

The method as recited in claim 13, wherein monitoring the area includes employing one or more of face recognition, weapon recognition and/or identifier recognition.

### Claim 16

A safety system, comprising:
a processor;
memory coupled to the processor, the memory including:
a person identifier application to determine whether a person is carrying a weapon and is authorized to do so in an area based on sensor data; and
an evaluator application to determine or predict an event in the area using sensor data collected from the area and to accordingly generate an output; and
a power controller activated in accordance with the output to activate at least one magnetic device.

### Claim 17 (depends on 16)

The system as recited in claim 16, wherein the person identifier application includes face recognition software to recognize the person.

### Claim 18 (depends on 16)

The system as recited in claim 16, wherein the person identifier application identifies a carried object to recognize the person.

### Claim 19 (depends on 16)

The system as recited in claim 16, wherein the at least one magnetic device includes an electromagnet positioned in the area.

### Claim 20 (depends on 16)

The system as recited in claim 16, wherein the evaluator application employs different types of sensing data, which are combined and compared to a threshold to determine or predict the event.
