A polymorphic antenna, including a metallic template configurable in at least first and second possible different three-dimensional shapes, the antenna, when configured in the at least first and second different three-dimensional shapes, having a common antenna feed point, a common balun coupled to the common antenna feed point; and a common dipole coupled to the common antenna feed point and to the common balun. The antenna operates in a common frequency band when configured in either of the at least first and second different three-dimensional shapes when fed via the common antenna feed point.

Conformable antenna

A multi-band antenna including a first antenna portion extending generally in a first plane, a second antenna portion, extending generally in a second plane and a hinged coupling providing coupling between the first antenna portion and the second antenna portion and permitting the second antenna portion to be folded over the first antenna portion such that the first plane and the second plane lie generally parallel.

Flat folding hinged antenna

A variable gain and variable beamwidth antenna including at least first and second generally planar antenna elements and an antenna element orienter for selectably varying the relative physical orientation of the at least first and second generally planar antenna elements, thereby selectably varying the gain and beamwidth of the antenna.

Variable gain and variable beamwidth antenna (the hinged antenna)

A fastening device (F) with first ( ) and second sides ( ) attaches a first device ( ) to a mounting rail ( ) of a second device ( ). A top section ( ) for mounting the first device extends from the first or second sides. The sides are adapted to removably clamp about the rail. A clamping member ( ) extends between the first and second sides. An extended end ( ) of the clamping member extends through the first side, and an opposing end ( ) is coupled with the second side. The clamping member extended portion ( ) is movably coupled to a single cam member ( ) operably mounted with the first side for drawing the sides closer together into a clamping position ( ) to mate the sides with the rail.

Sighting device

A method of achieving a focusing adjustment of an optical assembly, and of releasably locking this focusing adjustment, is described. A night vision weapon sight (10) which implements this method includes an objective lens assembly (14), an eyepiece lens (18), and an image intensifier tube (20) receiving light via the objective lens in order to provide an image via the eyepiece lens. The objective lens assembly includes a base portion (32) into which a lens housing (34) is threadably received. The threaded engagement of the base portion and lens housing is locked by a collet-like array of radially flexible fingers (42) each having a conical outer surface. A locking collar (44) having a conically tapering inner surface threadably engages the lens housing (34) and engages the collet fingers (42). Locking of the locking collar (44) is ensured by threaded engagement of a locking ring (54) with the locking collar (44) such that the prevailing torque tightens both of a pair of threaded engagements of opposite hand.

A binocular night vision device (BNVD) includes a pair of night vision monocular scopes which pivotally and adjustably depend from a central housing portion. The central housing portion and the two night vision monocular scopes cooperatively define a singular gas envelope, which allows the entire BNVD to be purged of moist air and back filled with dry nitrogen gas to prevent fogging while requiring only a single purging port. Further, the central housing portion contains a single battery and a single voltage step up circuit powering both image intensifier tube modules of the two monocular night vision scopes. In order to provide for interpupillary distance adjustment, the central housing portion and each of the monocular night vision scopes defines a sealed pivot mechanism which also allows for electrical connection between the central housing portion and each of the night vision scopes.

Binocular night vision device and method of making and using the device

A night vision sight is provided for use with a weapon, which includes an objective lens and a non-inverting image intensifier tube disposed along an optical axis, providing an intensified target image. The sight is focused by direct movement of the image intensifier tube relative to the fixed position of the objective lens. A reticle projector is disposed orthogonal to the optical axis and provides a collimated reticle image, the reticle image providing an aiming point for the weapon. The reticle image is superimposed over the target image, which are reflected into an eyepiece of the sight. The eyepiece has an axis between the optical axis and a sight line passing through a pre-existing sight provided with the weapon. Adjustment of the apparent position of the reticle to compensate for azimuth and elevation is accomplished by moving the reticle projector about crossed cylindrical bearings.

Night vision weapon sight

An eyecup insert is provided which allows easy attachment and removal of an eyecup from an associated night vision goggle. The eyecup provides a light secure seal when pressed against the head of an operator of the goggle. A connecting end of the eyecup has annular channel which engages the insert. The insert is ring shaped with a central aperture having a plurality of detents protruding inwardly of the aperture. The operator can form a snap-fit connection between the eyecup and the goggle by forcing the aperture over a circular flange which surrounds an eyepiece of the goggle until the detents have snapped passed the flange. The eyecup can be removed by reversing the installation procedure.
