Abstract: A tornado protection system and related methods are provided. The tornado protection system includes a concrete pad. At least two anchors are affixed to the concrete pad. A vehicle is in a grounded position on the concrete pad. At least two anchor straps are connected between the vehicle and the at least two anchors, respectively, wherein the at least two anchor straps are connected to at least two sides of the vehicle, respectively. The tornado protection system may allow the vehicle to remain grounded throughout the duration of a tornado having a wind speed of at least 65 MPH, a horizontal wind force of at least 2,959 lbs., and a vector wind force of at least 4,638 lbs.

Abstract: A method for generating visible light and a deceptive signature pattern for an emissions producing asset is disclosed. The method comprises illuminating at least one lighting assembly of the asset in a pattern. The pattern produces visible light synchronous with a signature of a wavelength in a substantially similar range as normal emissions of the asset. The method also comprises modulating a radiant intensity of the signature of the at least one lighting assembly between a minimum radiant intensity and a maximum radiant intensity in a repetitive cycle and operating a controller to regulate the pattern.

Abstract: A deceptive signature broadcast system for an aircraft or other emissions generating asset for generating an emissions pattern for masking the normal emissions signature of the aircraft or asset, and protecting it from emissions tracking intercept vehicles such as Infrared tracking missiles; the system includes at least two beacons mounted in a spaced apart arrangement orthogonal to the desired zone of protection, and bracketing the asset, such as on opposite wingtips of the aircraft for fore and aft protection; the beacon set is modulated from one end to the other with a sweeping pattern of emission intensity, deceptively indicating to the intercepting vehicle a lateral component of motion of the aircraft away from its true relative position within the intercept vehicle's field of view, thereby inducing the intercept vehicle to adopt an erroneous and exaggerated lead angle and course correction that results in a missed intercept trajectory.

Abstract: A U-shaped device wherein the presence or absence of a transparent liquid or solid between the legs of the U is sensed. The device utilizes a collimated light source mounted in one leg of the U with an associated limited field of view sensor in the other leg of the U-shaped device. The light source is placed so as to cause the transmitted light beam to strike the surface of the material to be sensed at an angle which is substantially off of a line perpendicular to the surface of the sensed material.The light sensor is placed so as to receive the light beam when there is no liquid or solid material present between the source and the sensor and to prevent the refractively bent light beam from striking the sensor when a transparent liquid or solid is placed between the light source and sensor.

Abstract: A display employing a horizontal and vertical grid of parallel infrared light beams in front of a cathode ray tube (CRT) face wherein a finger or other object may be placed against the face of the CRT to mark a spot thereon and the spot so marked will be detected by the interrupted beams. Infrared sources and detectors are located around the periphery of the CRT face and operate in different planes to more closely follow the curvature of the CRT face and thereby minimize parallax errors.

Abstract: A liquid level indicator consisting of a transparent rod within which is embedded a plurality of infrared emitters and photosensors. The infrared emitters and photosensors are mounted to a substrate which places the emitters and sensors in such a geometry as to cause total internal reflection off the transparent rod surface when an emitter-sensor pair is above the liquid level and to minimize internal reflection when an emitter-sensor pair is immersed in the liquid. The emitters are activated by electric current via conductive paths which are part of the supporting substrate. The sensors provide electric currents to an external readout device to indicate the absence or presence of liquid between emitter-sensor pairs. The liquid level indicator is made relatively insensitive to ambient light by shading the sensors from all but the desired infrared rays from the emitters. The liquid level indicator is hinged to allow a given length indicator assembly to be used in a variety of container depths.
