Abstract: There are disclosed aiming and target identification devices useful with firearms. One device includes a laser diode capable of emitting visible, infrared or ultraviolet light at the operator's selection to form a laser using a single or compound collimator. A single collimator can be repositioned at different distances from the laser source to ensure proper positioning to create a laser beam for the particular wavelength of light emitted from the laser diode. A compound collimator could have different collimating regions and be configured to rotate to cause the different collimating regions to receive light emitted from the laser source such that different light wavelengths are properly collimated without needing to alter the distance from the collimator to the laser diode.

Abstract: This application discloses systems and methods of a laser device which could be used to aim firearms. The device includes a laser diode capable of emitting two or more different wavelengths of light to form a laser using a collimator, for example a single collimator or a compound collimator. In embodiments using a single collimator, the collimator can be repositioned at different distances from the laser diode to ensure proper positioning to create a laser beam for the particular wavelength of light emitted from the laser diode. In embodiments using a compound collimator, the collimator could have different collimating regions and be configured to rotate to cause the different collimating regions to receive light emitted from the laser diode such that different light wavelengths are properly collimated without needing to alter the distance from the collimator to the laser diode.

Abstract: A shovel head counterweight for a helmet has been described. The counterweight has a mass that acts to counterbalance other objects attached to a helmet, such as night vision goggles. The shape and thin profile of the counterweight distributes the mass across the surface of the helmet to decrease strain on the user's neck. In addition, the underside of the counterweight is contoured to snuggly fit against the curvatures of the helmet. The counterweight also has one or more fasteners for removably attaching the counterweight to the helmet. The fastener(s) can also be used to attach a bar for use as a shovel. The counterweight has a digging edge for shoveling and a concave underside for scooping dirt or other material.

Abstract: A multi-purpose tool and tool attachments have been described. The multi-purpose tool comprises a utility bar that has an elongated structural member partly covered by an overmold, and universal connectors on its two ends. The cross section of the elongated member is crossed-shaped and has a plurality of recesses, which helps to optimize the weight-to-strength ratio of the bar. The universal connectors are male and female snap-fit engagements that allow for different tool attachments to be quickly and easily attached to the ends of the bar in both a right-hand and left-hand orientation. The connectors also allow several utility bars to be connected in series to make a longer utility bar. The tool attachments comprise a handle-hammer-pick attachment, a shovel head counterweight, a spear head, an extractor attachment, a breaching tool attachment, and a monopod sniper attachment. Each tool attachment is designed to have multiple functions.

Abstract: The helmet stabilization apparatus includes a helmet adapted to be worn by a user, a night vision goggle unit attached to a front portion of the helmet, and a removable counterweight attached to a rear portion of the helmet that balances with the weight of the night vision goggle unit, wherein said removable counterweight can be connected in a variety of manners, such as a magnetic means of connection, a hook and loop connection, or a mechanical means of connection. Furthermore, the helmet may provide staggered connections, such that the removable counterweight may be positioned on the helmet at the user's desired orientation. This allows the user to move the center of mass of the system such that it is self-stabilizing on the user's head. Moreover, the removable counterweight may be formed such that when it is removed, it may be coupled with an attachable handle to form a plurality of tools or weapons. This is beneficial in that it provides a collection of tools while only one object need be carried.
