An apparatus for securing and stabilizing devices which is further attached to a user. The apparatus is contoured along a surface to conform to a user's surface anatomy about the face, neck and upper chest area. An article mounting area, which is roughly rectangular in shape is located along the top of the apparatus. In one embodiment articles such as binoculars or cameras, are secured to the apparatus by way of straps. Straps or webbing couple the apparatus to the user. In one embodiment multiple straps attached to the apparatus are further attached to the user about the head, neck and upper chest areas. In one embodiment the apparatus is inflatable.

A main body of a viewing optic comprising at least one void in the main body.

A main body of a viewing optic comprising at least one void in the main body.

An endoscope and lens cleaning device assembly includes a tubular body, a visualization device including a lens, and a lens cleaning device. The visualization device is supported on a distal portion of the tubular body. The lens cleaning device is supported on the distal portion of the tubular body and includes an iris mechanism having a plurality of vanes. The vanes are movable between a first position in which the vanes are positioned radially outwardly of the lens of the visualization device and a second position in which the vanes cover the lens of the visualization device. Each of the vanes has a cleaning surface that is positioned to contact the lens of the visualization device as the vanes move between the first and second positions to clean the lens of the visualization device.

An automatic zoom-sensing riflescope display adapter (RDA) system can illuminate an iris of a user with a beam from a light emitter. The RDA system can activate a display which includes at least one graphical element visible by the user through an eyepiece. Additionally, the RDA system can focus an image of the iris on a sensor. The RDA system can determine a diameter of the iris from the image of the iris using an iris analyzer. The RDA system can develop a calibration table that correlates the diameter of the iris to a zoom level of an optical scope. The RDA system can estimate the zoom level of the optical scope from the diameter of the iris via the calibration table. Additionally, the RDA system can adjust, to match the zoom level, a font size of the at least one graphical element of the display.

A turret cover for a turret assembly. In one or more embodiments the turret cover includes an upper portion including a turret housing defining a battery recess and an illumination recess. An illumination assembly can be mounted in the illumination recess. In various embodiments, the illumination assembly includes a downwardly facing surface including a lighting element. In various embodiments, the turret cover includes a lower portion including an exterior sleeve portion of an at least partially transparent plastic material and a plurality of etched adjustment marks. In some embodiments, the lower portion is at least partially inserted into the illumination recess such that an upwardly facing edge of the exterior sleeve portion is positioned adjacent to the lighting element of the illumination assembly such that, in operation, the lighting element illuminates the plurality of etched adjustment marks via an edge lighting process.

An adjustment assembly for riflescopes and related methods are provided. In one example, an adjustment assembly includes a knob configured to rotate about an axis, a disc having a trace, a first sensor configured to measure a value relating to a particular portion of the trace, and a second sensor configured to sense complete revolutions of the knob about the axis. The riflescope also includes a processor configured to correlate the value with an angular displacement of the knob about the axis relative to a zero point.

An electro-optic observation device, in particular a thermal imaging device, is provided. The electro-optic observation device includes a handheld device housing, a lens group arranged in the device housing on the entrance side, an image capture unit arranged in the device housing on the image side with respect to the lens group, an image display unit arranged in the device housing, an eyepiece arranged on the exit side with respect to the image display unit, and also a control device configured to control at least the image display unit depending on user-specifically variable parameters. In addition, the electro-optic observation device includes, as input means for varying the parameters, a rotary wheel accessible on the device housing for access by a user.
