Abstract: A system for detecting the presence of ice crystals in a cloud comprising two thin walled semicylinder-shaped sensors, one having a concave inner surface and oriented longitudinally in a leading edge of an airfoil and the other having a convex outer surface being oriented longitudinally in the leading edge of the airfoil so that cloud water flows towards and into contact with the convex outer surface; a temperature controlling arrangement for heating the two sensors and maintaining them at a substantially constant temperature; and a comparison arrangement for finding a difference between (i) a power to maintain the temperature of the first sensor at its substantially constant temperature (ii) a power to maintain the temperature of the second sensor at its substantially constant temperature; and comparing the difference of the powers to a threshold value for evidencing the presence or predetermined amount of ice in the cloud water.

Abstract: A system and method for indicating the presence of ice water. The system includes a first sensor responsive to liquid water and ice water and a second sensor responsive to liquid water, power sources having output powers responsive to changes in the liquid water and the ice water contacting the respective sensors. A processor determines a first measure indicative of the ice water and the liquid water contacting the first sensor, determines a second measure indicative of liquid water contacting the second sensor and subtracts the second measure from the first measure to indicate a presence of the ice water.

Abstract: A system and method for providing a statistical measure of the size of liquid water droplets in a cloud, as well as a system and method for the detection and/or measurement of the presence of a cloud, liquid water content in the cloud and ice water content in the cloud, among other parameters.

Abstract: The present invention utilizes a series of optical and electronic elements to detect and image cancerous and/or pre-cancerous cells in living tissue. The invention further uses the images thus obtained to adaptively and dynamically shape a treatment light beam so as to maximize the beam's intensity in proportion to the areas with the most cancer or pre-cancer and to minimize the irradiation of normal tissue by the beam.

Abstract: An optical system of the present invention produces multiple simultaneous adjoining images on a single image plane. The optical system includes a first optical sub-system, a second optical sub-system, an aperture stop located between the first optical sub-system and the second optical sub-system, and a beam separating sub-system located at a plane substantially coincident with the aperture stop. The beam separating sub-system can receive electromagnetic radiation from the first optical sub-system and can separate the received electromagnetic radiation into multiple beams of electromagnetic radiation. The second optical sub-system images the multiple beams of electromagnetic radiation received from the beam separating sub-system into multiple images on an image plane. The beam separating sub-system includes one or more beam separating components and a mid-system filter system.

Abstract: A series of optical elements is used to produce multiple simultaneous adjoining images on a single image plane. A first, intermediate, image is produced using the first telecentric imaging lens. This intermediate image is produced at a plane coincident with an adjustable-size rectangular field stop. The rectangular field stop is mounted in a sub-housing that allows its free rotation. A second telecentric lens collimates the light from the intermediate image. This collimated light is next passed through an optical splitting means, which uses the principal of refraction to separate the light into multiple components. The optical splitting means is mounted in a sub-housing that allows its free rotation. From here, the light next passes through a third and final lens, which produces a second, final, image on a single, planar detection device. The final image consists of a plurality of identical copies of the intermediate image.

Abstract: A non-lethal method and devices for dispersing nuisance birds from a preselected area. Such nuisance birds disrupt many activities such as the steady flow of safely moving aircraft on runways and adjacent thereto, growing crops on farmland, playing golf and the use of the interior of large open buildings. The present method utilizes a series of bright light sources that are positioned adjacent the area from which the birds are to be dispersed. The light sources are activated to produce one or more beams of bright light that are moved in such a manner to produce a pattern of bright light in the vicinity of the birds to be dispersed. This action causes the birds to become sufficiently startled and disoriented so as to disperse these nuisance birds from the area to be cleared.

Abstract: A laser system for use in medical, industrial, commercial or research applications in which the location and energy and power density of a nonvisible (e.g., infrared or ultraviolet) laser beam is defined by a plurality of visible beams. Collimating optics are used to direct both the nonvisible and visible beams on the target, such that when the visible beam is in focus on the target, the nonvisible beam has the optimum energy and power density. One implementation of the invention is a self-contained hand-held surgical laser that provides surgeons with the optimal laser beam parameters for laser tissue soldering.

Abstract: A method and apparatus utilizing a series of optical components and systems which effectively detect and locate electromagnetic imaging or detection systems or devices, such as cameras and passive infrared detectors. A light source is arranged in a specially-prescribed manner, and is used in conjunction with imaging optics to illuminate an area. Any electromagnetic imaging or detection system in the illuminated area is detected with either the user's eye directly, or with detection optics to determine the existence of such electromagnetic imaging or detection system.

Abstract: A shield in combination with a plurality of high-brightness light sources used for riot, capture or other control of individuals. The light array utilizes a plurality of high-brightness light sources to provide a broad-area, high-intensity light for visual countermeasures. By providing a sudden burst of very bright light to surprise a subject and cause the subject to look away or close his or her eyes, the overseer, such as a police officer, can cause sufficient distraction to effectively capture or control the subject without harm.

Abstract: A self-contained non-lethal security device for providing an optimally effective and eye-safe beam for use as a high-brightness visual countermeasure. The security device has one or more wavelengths of laser or light-emitting diode (LED) light in a continuous or flicker mode in order to provide a glare or flashblinding visual effect. A flicker mode of two wavelengths at opposite ends of the visible spectrum (e.g., red and green) produces heightened disorientation to the adversary. Replacing one or all of the laser light source with LEDs for shorter range applications reduces the overall cost of such a security device.

Abstract: A self-contained laser illuminator module for primary use in a laser security device which is adapted to produce an optimally effective and eye-safe laser beam for use as a laser visual countermeasure. The laser illuminator module includes control electronics having a high-power laser adapted to generate a preselected wavelength and intensity, a fiber optic means in optical communication with the control electronics, and a means for mounting to a security device having a collimating lens. The present invention generates a laser beam to illuminate or create temporary visual impairment of a potential adversary which results in hesitation, delay, distraction, surrender or retreat.

Abstract: This invention provides a fixed or portable non-lethal laser security device and method for use of such device as a non-damaging weapon and security system to provides warning and visual impairment upon an intruder. At a predetermined laser wavelength and intensity, this invention utilizes laser light in the visible portion of the wavelength spectrum to create temporary visual impairment, hesitation, delay, distraction, and reductions in combat and functional effectiveness through the effects of glare, flashblind, and psychological impact. The preferred embodiment of the laser security device in the present invention involves the use of laser technology with a remotely operated security system.

Abstract: A system for characterizing contamination or integrity information from within a pipe, including a flexible tubular membrane which is extendable within the pipe and inflatable to a diameter effective to urge the tubular membrane against the rigid wall. The tubular membrane has a first end and a second end, and is initially rolled up and connected to a reel inside of a deployment system. A tether connects the deployment system to a characterization tool retained within the tubular membrane, which is attached adjacent to the second end of the tubular membrane. When the system is engaged, pressurized fluid enters the tubular membrane causing the membrane to invert and distend into and through the pipe's interior.
