## Abstract

A non-lethal dazzling device includes a laser operable in the visible spectrum. The laser can be a relatively low-powered laser, such as a laser having a maximum output power of 2.5 mW, or it can be a higher-powered laser with a drive circuit that lowers the maximum output power to a safe level based on the range of the hostile target from the laser. In certain embodiments, disclosed non-lethal dazzling device can be coupled to the bridge of a binocular device.

## Claims

### Claim 1

A non-lethal binocular dazzling device comprising:
a first optical housing including a first eye piece, a first objective lens, and a first mechanical focal element, the first optical housing being substantially cylindrical in shape;
a second optical housing including a second eye piece, a second objective lens, and a second mechanical focal element, the second optical housing being substantially cylindrical in shape;
an articulated bridge coupling the first optical housing to the second optical housing;
a dazzling module operatively coupled to the articulating bridge, the dazzling module comprising:
a laser drive circuit;
a pushbutton operatively coupled to the laser drive circuit whereby the laser drive circuit is activated by a press of the pushbutton and produces a laser drive power;
a dazzling laser coupled to and driven by the laser drive circuit, whereby the dazzling laser produces a beam proportional to the laser drive power.

### Claim 2 (depends on 1)

The non-lethal binocular dazzling device of claim 1 wherein the dazzling module further comprises:
a first power programming circuit coupled to the pushbutton, whereby the first power programming circuit is activated by a press of the pushbutton and whereby the first power programming circuit is coupled to the laser drive circuit and is adapted to control the laser drive circuit to produce a low laser drive power;
a second pushbutton; and
a second power programming circuit coupled to the second pushbutton, whereby the second power programming circuit is activated by a press of the second pushbutton and whereby the second power programming circuit is coupled to the laser drive circuit and is adapted to control the laser drive circuit to produce a high laser drive power.

### Claim 3 (depends on 1)

The non-lethal binocular dazzling device of claim 1 wherein the dazzling module is coupled to an upper surface of the articulated bridge.

### Claim 4 (depends on 3)

The non-lethal binocular dazzling device of claim 3 wherein the pushbutton and the second pushbutton are mounted to a top surface of the dazzling module.

### Claim 5 (depends on 4)

The non-lethal binocular dazzling device of claim 4 wherein the pushbutton top surface of the dazzling module has a left half and a right half, and wherein the pushbutton is mounted on the left half of the top surface of the dazzling module and the second pushbutton is mounted on the right half of the top surface of the dazzling module.

### Claim 6 (depends on 1)

The non-lethal binocular dazing device of claim 1 where it the articulated bridge comprises a first hinge coupled to the first optical housing and a second hinge coupled to the second optical housing.

### Claim 7 (depends on 1)

The non-lethal binocular dazzling device of claim 1 further comprising a focus knob coupled to the first mechanical focal element and the second mechanical focal element, whereby operating the knob will modify the focus for the first mechanical focal element and the second mechanical focal element.

### Claim 8 (depends on 7)

The non-lethal binocular dazzling device of claim 7 wherein the laser drive circuit is adapted to generate a laser drive power that is based on the setting of the focus knob.

### Claim 9 (depends on 1)

The non-lethal binocular dazzling device of claim 1 wherein the dazzling module is integrated into the articulated bridge.

### Claim 10 (depends on 9)

The non-lethal binocular dazzling device of claim 9 wherein the articulated bridge includes a single unit-directional hinge disposed between the first optical housing and the second optical housing.

### Claim 11 (depends on 9)

The non-lethal binocular dazzling device of claim 9 wherein the dazzling module further comprises:
a processor coupled to the pushbutton and the laser drive circuit, wherein the pushbutton generates a pushbutton signal when pressed, and wherein the processor is adapted to program and activate the laser drive circuit to produce a predetermined laser drive power when the pushbutton signal is received by the processor.

### Claim 12 (depends on 11)

The non-lethal binocular dazzling device of claim 11 further comprising:
a second pushbutton coupled to the processor, wherein the second pushbutton generates a second pushbutton signal when pressed;
a rangefinder transmitter coupled to the processor;
a rangefinder receiver coupled to the processor;
wherein when the processor receives the second pushbutton signal the processor activates the rangefinder transmitter and the rangefinder receiver, wherein the rangefinder transmitter is adapted to produce a range finding beam, and the rangefinder receiver is adapted to receive a range finding reflection and wherein the rangefinder receiver is adapted to report a range value to the processor.

### Claim 13 (depends on 12)

The non-lethal binocular dazzling device of claim 12 wherein the processor is adapted to program the laser drive circuit to produce a laser drive power proportional to the range value reported to the processor.
