The present invention relates to night vision devices, and more particularly, to night vision apparatuses utilizing gas filled tubes and IR illuminator assemblies.

2. Description of the Related Art.

Applicant believes that one of the closest references corresponds to U.S. Patent No. 5,396,069 B issued to Craig, et al. on March 7, 1995 for Portable monocular night vision apparatus. However, it differs from the present invention because Craig, et al. teach a monocular night vision apparatus employing an infrared energy spectrum source of illumination and a camera lens and night vision image intensifier combined receiver apparatus into a hand-held portable package. The night vision transmitter apparatus includes a laser diode energy source that is coupled to an aperture controlled and focus controlled optical system and driven by an electronic closed- loop feedback energization circuit, which employs self-contained battery sources of energy. Operating modes and intensities of the light source are provided through a plurality of signal inputs to the closed feedback loop of the laser diode energy source. Disturbance of the closed feedback loop by reflected energy within the optical transmitter apparatus is precluded by the use of feedback prevention optical alignment in the transmitter's optical system.

Applicant believes that another reference corresponds to U.S. Patent No. 5,444,568 B issued to Williams, Jr., et al. on August 22,

1995 for Consumer night vision viewing apparatus. However, it differs from the present invention because Williams, Jr., et al. teach a night vision goggle device fabricated for consumer use. The device employs interpupillary and diopter adjustments for each eye of the user. The combined adjustment mechanism incorporates manually operable control knobs located on the housing and one knob for each of the eye pieces. Each control knob is capable of moving both in a forward and rear mode and in a transverse mode. The knob can provide diopter focus adjustment for a front to back motion and for lateral movement or transverse movement the control provides for interpupillary adjustment. The movement of the knob and the removal of pressure or force from the knob enables the optical assemblies to be locked in position by a friction fit.

Applicant believes that another reference corresponds to U.S. Patent No. 5,495,364 B issued to Gary L. Palmer on February 27,

1996 for Night vision binoculars. However, it differs from the present invention because Palmer teaches a night vision binocular assembly capable of converting low light and infrared energy into a visible image. The night vision binocular assembly includes at least one objective lens assembly, image intensifier tube, collimator lens assembly and diopter cell assembly encased in an easy to assembly waterproof housing. The objective lens assembly, image intensifier tube, collimator lens assembly and diopter cell assembly are all supported by a common base structure within the housing. Variations caused by thermal expansions and contractions are evenly distributed among the various optical elements, thereby preserving a predetermined optical relationship between those elements. Simple button controls are used to operate and adjust the night vision binocular assembly. The button controls are disposed on a common circuit board. An elastomeric structure is disposed between the circuit board and the interior of the binocular housing. The circuit board is affixed to the interior of the binocular housing in a manner that compresses the elastomeric structure against the binocular housing, which is further sealed to the housing to provide a water tight seal. The elastomeric structure has switch membranes or domed portions which extend through apertures in the housing creating both a fluid impermeable seal with the housing and a means for the tactile engagement of the switches on the below lying circuit board.

Applicant believes that another reference corresponds to U.S. Patent No. 5,729,016 B issued to Klapper, et al. on March 17, 1998 for Low cost night vision for nonmilitary surface vehicles. However, it differs from the present invention because Klapper, et al. teach a low cost night vision system for use in connection with law enforcement vehicles, marine vessels, and other nonmilitary surface vehicles. It includes a night vision camera having an array of uncooled detectors. A mechanism is provided for adjusting the pointing angle of the night vision camera in response to scan control signals. Output signals from the uncooled detectors are further processed into a standard video format and displayed on a conventional display located, for example, within a vehicle or marine vessel.

Applicant believes that another reference corresponds to U.S. Patent No. 5,737, 131 B issued to Gary Lynn Palmer on April 7, 1998 for Night vision monocular. However, it differs from the present invention because Palmer teaches a night vision monocular that includes an objective lens subassembly for receiving low intensity and/or infrared light. The objective lens subassembly focuses the light onto an image intensifier tube that converts the light into a visible image. The visible image passes through a collimator subassembly that collimates the visible image. Finally, the collimated image is viewed through an eyepiece subassembly. The objective lens subassembly, image intensifier tube, collimator subassembly and eyepiece subassembly are each separately manufactured subassemblies that are encased in subhousings and are ready to be assembled into a larger optical device. The housing of the night vision monocular is a two-piece structure, having a first half and an opposite second half. Partitions extend inwardly from a plurality of locations on both halves of the housing. The partitions are contoured and positioned to abut against and retain the various subassemblies within the night vision device. At least two partitions from each half of the housing abut against and support the objective lens subassembly, the image intensifier tube, the collimator subassembly and the eyepiece subassembly. The partitions within the housing are the only elements of positioning and optically aligning the various subassemblies. Consequently, no adhesive or mechanical fasteners are needed to retain components within the housing. The housing itself need not be precision machined.

Applicant believes that another reference corresponds to U.S. Patent No. 5,751 ,344 B issued to Robert Alan Schnee on May 12, 1998 for Navigation system for a marine vessel in low light conditions. However, it differs from the present invention because Schnee teaches an aid for marine navigation that includes a low- light video camera mounted within a weatherproof enclosure on a vantage point of a marine vessel for improved night vision. A conventional video camera is also mounted with the low-light video camera for daytime viewing. Video signals from the cameras are automatically selected depending on light conditions for transmission to a cabin of the vessel. Motors rotate the housing in a horizontal plane and in a vertical plane for enabling remote- controlled aiming of the cameras from the helm of the marine vessel. Sensors provide information on azimuth and elevation of the cameras for overlaying the video signal transmitted from the camera housing with this information for display with the video image on a monitor near the helm. Information on longitude and latitude, as well as vessel velocity and direction, from a global satellite positioning system receiver is also displayed. The overlayed video signal is RF modulated on to a predetermined channel for distribution to television receivers in other locations on the vessel.

Applicant believes that another reference corresponds to U.S. Patent No. 5,763,882 B issued to Klapper, et al. on June 9, 1998 for Low cost night vision camera. However, it differs from the present invention because Klapper, et al. teach a low cost infrared camera for night vision. The camera is disposed within a housing having an infrared transmissive window disposed at an input aperture thereof. A compact optical arrangement is disposed within the housing to focus energy from the window onto a focal plane array. A chopper disk is positioned between the reflective optical arrangement and the focal plane array to establish a reference level for the array and to facilitate a sequential readout thereof. A signal processing circuit is included for processing the output of the array for display on a standard video screen. Thus, the problems with uncooled detectors are overcome by use of a fast optical system in combination with an uncooled detector. The fast optical system provides a high signal level to the uncooled detector, thereby compensating for losses in collection of thermal radiation. Reflective optical systems can be manufactured inexpensively from plastic or aluminum and reduce the need for expensive infrared materials commonly used in military systems. The combination of the fast optics and uncooled detector provides a low cost thermal camera for night vision.

V. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring now to the drawings, the present invention is a night vision apparatus, and is generally referred to with numeral 10. It can be observed that it basically includes camera assembly 20, switch assembly 130, and display assembly 160.

As seen in figure 1 , camera assembly 20 comprises camera housing 30, infrared illuminator assembly 70, and base assembly 90. In a preferred embodiment, camera assembly 20 operates at a wavelength of approximately between 400 to 1200 nm allowing for visibility while viewing display assembly 160 in low light and/or dark environments, such as during no light, low light, and/or minimal light nighttime conditions. Camera assembly 20 captures high- resolution images in low light and/or dark environments, such as during no light, low light, and/or minimal light nighttime conditions.

Camera assembly 20 and display assembly 160 are both electrically connected to switch assembly 130. Infrared illuminator assembly 70 has connection 80, as seen in figure 2, from which extends camera cable 1 10 having camera connector 1 12. Camera connector 1 12 connects with extension cable 114 through extension connector 1 16. Extension cable 1 14 further comprises extension connector 118, which connects with connector 142 of switch cable 140. Display assembly 160 comprises display cable 170. Display cable 170 comprises display connector 172, which connects to switch housing connector 138.

Battery assembly 180 is also electrically connected to switch assembly 130. Battery assembly 180 comprises battery housing 182, battery switch 184, which is an on/off switch, and at least one battery, not seen. Battery cable 186 extends from battery housing 182 and connects to battery connector 188, which connects with connector 146 at an end of switch cable 144. Battery assembly 180 provides power / energy required for operation of present invention 10. As seen in figure 2, camera housing 30 comprises top face 32, bottom face 34, and front face 36 having aperture 38. Aperture 38 aligns with lens 42.

Infrared illuminator assembly 70 comprises housing 72, which houses infrared illuminator lens 74 and infrared illuminator 76, as seen in figure 3. Infrared illuminator assembly 70 is attached to bottom face 34 of camera housing 30. Supporting structure 78 and connection 80 extend from housing 72.

Base assembly 90 comprises upper clamp wall 92, lower clamp wall 94, screw handle 96, base supporting structure 98, base 100, and suction cup 102. Upper clamp wall 92 holds supporting structure 78, and lower clamp wall 94 holds base supporting structure 98, securing camera housing 30 and infrared illuminator assembly 70 onto base assembly 90. Screw handle 96 secures upper clamp wall 92 and lower clamp wall 94 onto respective supporting structure 78 and base supporting structure 98.

Base assembly 90 further comprises base lateral wall 104 that extends from base protrusion structure 98 to base 100. Base lateral wall 104 comprises protrusions 106 to grasp and rotate base 100 for mounting and removing suction cup 102 from a surface. Suction cup 102 secures camera assembly 20 onto a surface, whereby base lateral wall 104 rotates onto base 100 while a vacuum forms between suction cup 102 and the surface to mount thereon.

As seen in figure 3, camera housing 30 further comprises charge-coupled device (CCD) image sensor 40, lens 42, adaptor 44, and tube 46.

CCD image sensor 40 is a highly sensitive photon detector. CCD image sensor 40 is divided up into a large number of light- sensitive small areas, known as pixels, which can be used to build up an image. A photon of light, which falls within an area defined by one of the pixels, converts into one or more electrons, and the number of electrons collected will be directly proportional to the intensity of the scene at each pixel. CCD image sensor 40 is highly sensitive to a wide spectrum of light, approximately from 400nm to near infrared light (800 to 1200 nm). As this wavelength is “invisible” to the human eye yet readily detected by CCD image sensor 40, images can be produced even in low light.

In CCD image sensor 40, pixels are represented by p-doped MOS (Metal- Oxide- Semiconductor) capacitors on a silicon semiconductor substrate. These capacitors are biased above the threshold for inversion when image acquisition begins, allowing the conversion of incoming photons into electron charges at the semiconductor- oxide interface, and CCD image sensor 40 is then used to read out these charges. In order to more efficiently process low intensity light levels, CCD image sensor 40 used in present invention 10 has coupled a low light specific chip set with leading edge shutter control firmware, not shown. This basically allows CCD image sensor 40 to dynamically increase or decrease register shifting and charge dump times on each capacitor (pixel). There are just under ½ million pixels/ capacitors on each CCD image sensor 40. More specifically, CCD image sensor 40 takes an incoming photon of light and photo reactively convert it to an electric charge value through a photo diode to an individual capacitor and discharges each capacitor through a digital register that is time based. The register output is then processed into a streaming image. Each micro- sized capacitor represents a pixel.

Lens 42 has a focal length of approximately 25 mm or 50 mm. In a preferred embodiment, lens 42 has a focal length of approximately 25 mm and an F-stop of approximately 1.4. For off road application, lens 42 will be either 25 mm or 50 mm with an F- stop 1.4. F-stops are aperture setting of lens 42. As a basic rule, the wider the aperture, the more light is collected. The F values are numerically inverse, meaning that an F stop of 1.4 is twice as wide as a 2.8. The wider the F stop can be for present invention 10, the more light lens 42 will collect, which in low light/ dark conditions is good. In a preferred embodiment, lens 42 is a high definition 25 mm FI .4 C-mount lens. Lens 42 generally focuses on distant objects. Lens 42 has lock down screws, not seen, to maintain focus and aperture settings. Adaptor 44 is a C to CS adaptor. In a preferred embodiment, adaptor 44 is a chrome ring and is positioned between CCD image sensor 40 and lens 42. In a preferred embodiment, tube 46 is 5-PSI Nitrogen (N2) filled.

CCD image sensor 40 is sensitive to near infrared (IR) light (750nm to 1000+ nm). Therefore, CCD image sensor 40 benefits from external IR light sources. Infrared (IR) illuminator assembly 70 is small, measuring approximately 3” long and 1.75” wide. IR illuminator assembly 70 comprises infrared (IR) illuminator 76. In a preferred embodiment, IR illuminator 76 emits light at a wavelength of approximately 840 nm. According to present invention 10, a spectral response of CCD image sensor 40 to an 840nm external light source is about 70%.

In a preferred embodiment, IR illuminator 76 is an approximately 2.5 watt illuminator that produces approximately a 10° main beam pattern. This is a nominal beam pattern with sufficient illumination to allow detection of small objects, as a paper cup, at over 100 yards and larger objects, as bridges and structures, at over 1 mile.

Infrared illumination is only necessary in extremely dark areas, usually with little or no moonlight and/or heavy overcast conditions. In so far as putting a scale factor on darkness, while subjective, the below graphic illustrates most conditions that will be encountered using present invention 10.

The following Table 1 shows inland darkness scale factors:

Condition Poorly lit, undeveloped, overcast, 1/4 moon

Table 1

According to the above table, IR illuminator 76 would only be required in conditions 5 and 6. In operation, present invention 10 collects as much light as possible to produce an optimum image. This is evident when using present invention 10 on a full moon night as opposed to the little or no moonlight and/or heavy overcast conditions. As seen in figure 4, display assembly 160 comprises frame 162, display 164, control buttons 166, and holes 168 for a speaker, not seen, within frame 162. A second base assembly 90 secures display assembly 160. Display 164 receives and shows images captured by camera assembly 20.

As seen in figure 5, switch assembly 130 comprises switch housing 132 having infrared (IR) illuminator switch 134, switch 136, which is an on/ off switch for display assembly 160, and switch housing connector 138. Switch assembly 130 activates camera assembly 20, and IR illuminator switch 134 activates IR illuminator assembly 70, seen in figure 1.

As seen in figure 6, present invention 10 may be mounted onto watercraft 200. Watercraft 200 may be a ship, boat, yacht, houseboat, sailboat, or any other marine vessel. Present invention 10 may also be mounted onto any vehicle, such as but not limited to, an automobile, truck, recreational vehicle, motorcycle, three- wheeler, or four wheeler including all-terrain vehicles. Present invention 10 allows users to see channel markers, bridge pylons, debris, and anything else that might be a threat to watercraft 200 or a vehicle. Thus, providing the users a level of situational awareness previously unavailable. Many recreational activities that were once awkward at night, such as boating and hunting, are increasingly integrating present invention 10. In an alternate embodiment, present invention 10 may draw power / energy from watercraft 200 and not battery assembly 180, whereby connector 146 plugs into an outlet of watercraft 200, not seen.

Night vision is defined by two basic components, the ability of spectral sensitivity and the intensity of the wavelengths. Spectral sensitivity is an animal’s ability or a sensor’s ability to detect specific wavelengths of light. Wavelengths of light are measured in Nanometers (nm). One nanometer is one billionth of a meter. Visible light to humans falls within 400nm to about 770nm. In 430nm appears violet (UV) to a human being and 770nm appears deep red. Intensity of the wavelength is essentially determined by the amplitude of each wavelength, which is defined in many different terms and units of measurement. Basically, the higher the amplitude, the brighter the wavelength (light).

Present invention 10 is designed for operational parameters in low light/ night time environments, and to provide a realistic depth perception of distant objects due to lens 42 and sensor settings. Present invention 10 provides users with a more navigable system as opposed to wider view systems. Even in very dark conditions, present invention 10 gives the operator a realistic field of view and hence, frame of visual reference. CCD image sensor 40 has low light sensitivity that works well in conjunction with IR illuminator 76, to perform in zero light environments. CCD image sensor 40 also allows present invention 10 to provide a very standard 60 Hz video output and thus can be viewed on display 164, as seen in figure 4. CCD image sensor 40 also lends itself well to optional upgrades such as wireless video transmission, video recording, portable versions and more.
