Abstract: An improved helmet mounting device for an optical device, such as a night vision device, is provided. The mounting device herein includes sliding carriage arms and a pivot member for pivoting the viewing device up and away from the user's line of sight. In the depicted preferred embodiments, an optional reinforced mounting fastener system is provided. In another aspect, a movable sensor element may provided on the helmet mount for controlling operation of an attached vision device. In still further embodiments, a breakaway mechanism is provided which allows the user to select between a rigid attachment between the helmet and the optical device and a breakaway attachment wherein the optical device will break away from the helmet when an applied force exceeds a threshold amount of force.

Abstract: A handgrip apparatus for firearm includes a hollow housing defining a handgrip surface and forming an enclosure. A fastener is connected to the housing for removably attaching the handgrip apparatus to a fore-end portion of a firearm. A retractable leg assembly is movable between a retracted position and an extended position and includes a pair of pivoting legs usable as a bipod support when the leg assembly is in the extended position. In one aspect, one or more switches for controlling operation of one or more electronic devices are coupled to the handgrip apparatus. One or more connectors are electrically coupled to the one or switches and are adapted to be electrically coupled to one or more electronic devices. In another aspect, a handgrip apparatus having a pivoting attachment between the fastener and the housing positions is provided. In another aspect, a handgrip apparatus includes integrated conductors in the fastener.

Abstract: A switch apparatus for a flashlight includes a housing adapted to attach to a flashlight and defining an interior cavity. A processor is coupled to a first switch and a second switch. The first switch is user actuable and coupled to an input of said processor. The second switch is housed within said interior cavity and coupled to an output of the processor and is an electronically-controlled switch operable to selectively actuate the flashlight in response to actuation of said first switch. In a further aspect, a flashlight apparatus includes the switch apparatus and a flashlight.

Abstract: A breathing apparatus is operable in self-contained and filtered modes of operation. In the self-contained mode of operation, a breathable gas is delivered to a user from a self-contained source of breathing gas. In a second, filtered mode of operation, a suction source draws ambient air through a filter removing contaminants and delivers filtered ambient air to the user. A method of delivering air to a subject is also provided.

Abstract: A helmet- or head-mounted video recording system is provided for mounting on a piece of head gear such as a head-protective helmet. The system includes a camera module attachable to the head gear, including a first video camera integrated into the camera module for generating a video signal. A recording module is removably attachable to the head gear and is adapted to receive the video signal and store data representative of the video signal. A power supply module is removably attachable to the head gear and is electrically connectable to the camera module and the recording module.

Abstract: In one aspect, the present disclosure relates to improved cooling module of a type for circulating water or other cooling fluid through a tube-lined cooling garment system. In another aspect, the present disclosure relates to a central shaft for the transmission of rotational power or torque. In yet another aspect, the present disclosure relates to a hydration system which may be employed in connection with the cooling module described herein.

Abstract: Pivoting helmet mounts for an optical device are provided. In one aspect, a breakaway connector which is selectively configurable between breakaway and nonbreakaway configurations is provided. In a further aspect, a strap mount system for securing the helmet mount to the helmet employs a rotating ratchet assembly to adjust tension in the strap. In another aspect, a helmet mount for an optical device comprises a track assembly attached to a helmet to allow stowing of the optical device in a further retracted position. The track mount system may further include electrical connectors for attaching a power supply and an electronic device. In another aspect, a mounting bracket allows helmet-mounted optics to be shared with a weapon accessory mount. In a further aspect, a optical sighting device for a weapon combines a reflex sight a night vision goggle to allow targeting at night or in other low-light conditions.
