The invention relates to an interface for connecting an optical device and a mobile support which cooperates securely with an imprinted element, the interface having a base arranged to be inserted into the imprinted element, the base being a hollow body. The base accommodates mechanical play compensating structures which are movably mounted within the hollow body so as to project and are arranged in order to bear against a wall of the imprinted element.

Optical bridges including a bridge body configured to be mounted directly or indirectly onto a head-worn device and at least one rail operatively engaged with the bridge body, in which the at least one rail having a first end and a second end. The optical bridges also include a first stopblock located at or proximate to the first end and a second stopblock located at or proximate to the second end. The at least one rail has a first side portion located between the first stopblock and the bridge body and a second side portion located between the second stopblock and the bridge body. Systems including an optical bridge and one or more optical devices directly or indirectly releasably coupled to the optical bridge are also provided.

The dual tube night vision device comprises a pair of independently pivoting night-vision monoculars connected to a bridge member. Each night-vision monocular is attached to the bridge member by a rotating arm and comprises a pod containing an image intensifier tube. Each arm allows the attached night-vision monocular to move through a rotational travel path, between a stowed position and a deployed position. The dual tube night vision device is configured to detect when the night-vision monoculars are, individually or collectively, moved to a stowed position and then temporarily cut off power to the stowed monocular(s) to increase battery runtime. Power is automatically restored, individually or simultaneously, to the night-vision monoculars when they are rotated back to deployed positions. The dual tube night vision device uses one or more accelerometers to detect when the night-vision monoculars, individually or collectively, are moved to the stowed position and the deployed position.

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, the disclosed non-lethal dazzling device can be coupled to the bridge of a binocular device.

A helmet accessory mount system may include a shroud configured to be coupled to a helmet and an arm assembly having a first arm configured to rotatably couple to the shroud. The system may also include an accessory interface configured to coupled to an accessory and configured to engage the arm assembly. The arm assembly may be configured to move from a deployed position to at least one storage position. The accessory may be configured to be positioned between the accessory interface and the helmet when the arm assembly is in the at least one storage position.

A diopter adjustment mechanism comprises a scope tube with a first female thread and a second female thread. The first female thread has a first pitch and is disposed on the scope tube forming a spiral thread and lands between the spiral threads. The second female thread has a second pitch and is disposed on the lands of the first female thread. A jam nut has a male thread corresponding to and engaging the second female thread.

A display device includes: a first closed-bottom lens tube including a first display part on the closed bottom for displaying a first image; a second closed-bottom lens tube including a second display part on the closed bottom for displaying a second image; an adjustment mechanism including a first rod that extends from the first lens tube and a second rod that extends from the second lens tube and is rotatably connected to the first rod; and an image outputter that outputs the first and second images to the first and second display parts, respectively. The image outputter, in accordance with the angle of rotation of the first and second rods of the adjustment mechanism, controls and outputs the first and second images to bring the horizontal directions thereof closer to the arrangement direction of the first and second lens tubes.
