A weapon mount for mounting a night vision device to the receiver rail of a weapon. A self-device adjusting cam operated connection device is present at one end region of the mount for attaching to the receiver rail, while the night vision device is connected at the other end region of the mount with a knob operated mounting screw. The knob and mounting screw are a one piece design and the mounting screw is captivated by an E-clip. The cam operated connection device may be adjusted to accommodate different size receiver rails by the provision of compressible means, such as Belleville washers.

Devices in which components of medical kits are carried are identifiable by means other than by the naked eye. The means for identification is attached to or integral with the device and may comprise raised and lowered surfaces that can be read by touch; serrations disposed on an edge or surface; a fluorescent coating viewable under infrared or ultraviolet light; or a pattern that is viewable using a thermal imaging device such as night vision goggles. A package for retaining a medical item includes an identifying element of a material that is selectively viewable in response to light attributes of the material. A device for the visual identification of a package containing a medical item includes an identifying element comprising a material that is visually discernible in reduced-light environments via the use of night vision devices.

An advanced image intensifier assembly provides enhanced functionality. A grounded photocathode provides shielding from electromagnetic interference, improving the ability to work in multiple light conditions. Bi-directional wireless communication and non-volatile storage allow critical information to be permanently stored and read wirelessly at a scanning station, easing in identification of units. Because bi-directional communication components can be embedded within an image intensifier assembly, existing end-user night vision devices can be upgraded by simply replacing the image intensifier assembly. For enhanced safety, a programmable shutdown capability is provided. This renders the device inoperative in the absence of continuous input, either wireless or manual, from an authorized operator, thus rendering the device useless if captured by enemy combatants. Finally, direct 1-volt operation enables the device to be powered by, for example, a single AA battery.

A medical dressing for chest wounds, including a one-way valve that can be covered so as to protect against intrusion of airborne contaminants and to prevent passage of fluids in either direction, and including indicia visible using night vision devices but not visible in visible light to the naked eye in some embodiments. The indicia visible using night vision devices may be included in other medical apparatus, as well, so that the medical dressings or other apparatus can be used effectively during darkness, in combat situations, without being seen by enemy combatants not equipped with night vision devices.

An aiming device is configured to generate an infrared cross on a target. The cross having a principal wavelength above the wavelength detectable by image intensification night vision devices. A night vision system having a short wave infrared detector includes an illuminator having a principal wavelength above the wavelength detectable by image intensification night vision devices. A beacon is configured to generate light at a wavelength above which can be scene with image intensification night vision devices.

Embodiments of the invention pertain to a method and apparatus for sensing infrared (IR) radiation. In a specific embodiment, a night vision device can be fabricated by depositing a few layers of organic thin films. Embodiments of the subject device can operate at voltages in the range of 10-15 Volts and have lower manufacturing costs compared to conventional night vision devices. Embodiments of the device can incorporate an organic phototransistor in series with an organic light emitting device. In a specific embodiment, all electrodes are transparent to infrared light. An IR sensing layer can be incorporated with an OLED to provide IR-to-visible color up-conversion. Improved dark current characteristics can be achieved by incorporating a poor hole transport layer material as part of the IR sensing layer.

The invention discloses a night-vision device with ranging function, and belongs to the field of monitoring devices. The technical scheme is that: the night-vision device comprises a pulse laser and an ICCD camera with a gate, wherein the ICCD camera can realize range-gated imaging; a range-gated synchronous controller is arranged between the pulse laser and the ICCD camera; the range-gated synchronous controller can make pulses of the pulse laser and the ICCD camera correctly matched on time sequence, separate useful signals reflected by background radiation and an object due to back scattering in different ranges according to the time sequence, so that the useful signals reflected by the detected object reach the camera and are imaged just in the gate working time of the camera. The night-vision device has the advantage that: the night-vision device automatically measuring the range between the camera and the object through the pulse laser and the ICCD camera with the range-gated imaging function, and makes the monitoring more effective.

The invention relates to a high-definition laser night-vision viewer, which belongs to the field of laser illumination devices. The high-definition laser night-vision viewer is characterized by comprising an infrared laser illuminator and a high-definition camera, wherein the infrared laser illuminator and the high-definition camera are respectively connected with a control module of a controller, the controller is further provided with a communication module and a driving module, and the control module is further connected with the communication module and the driving module simultaneously; the control module is responsible for integral operation of the night-vision viewer and can automatically detect the light intensity of external environment, open/close the infrared laser illuminator and control the black and white/color conversion of the high-definition camera simultaneously, can be communicated with the communication module and a background device and control the driving module so that the night-vision viewer rotates to an appointed position; the communication module transmits high-definition video and control commands between the night-vision viewer and the background control device; and the driving module drives the night-vision viewer to actuate. The high-definition laser night-vision viewer has the characteristics of clear imaging, long night visual range, good laser synchronization effect, strong monitoring elusiveness, and the like and has the beneficial effect of solving the problem of high-definition monitoring at night effectively.

A night viewer (10) is adaptable to generate an enhanced image suitable for viewing through an optical scope (16). An input end (18) of the viewer (10) receives the image to be enhanced through an objective lens (20). An image enhancing unit (22) enhances the image. The enhanced image is optically transmitted from a display (28) to the ocular lens (24) of the scope (16). The display (28) is operably connected with the image enhancing unit (22) to display the enhanced image. A Risley prism (30) located in an image path (32) is used to controllably adjust and to maintain boresight alignment (36).
