Abstract: A plurality of road-to-traveler feedback (“RTF”) devices integrated with a plurality of electronic computing devices transmits location data to a server. The server transmits to the RTF devices traffic signal timing data based on the location data. RTF devices present suggested velocities based on the traffic signal timing data, such that if a traveler conformed to the suggested velocities and other travel-related data, the traveler would position himself into a geographic region on a roadway in which the traveler is ensured to avoid red lights and other traffic impediments. The server is operatively connected to traffic controllers and receives traffic light state data. The server facilitates a plurality of geographic regions based at least on the traffic light state data and detected travelers on roadways, wherein each of the geographic regions are synchronized to allow continuous traffic flow for the travelers positioned therein.

Abstract: Designs for constructing a surface with variable emittance are described. This is achieved by making a surface where the emissivity varies on a scale smaller than the resolution of a thermal imager viewing the surface. One design utilizes many cylindrical surfaces with their axis parallel and their surfaces nearly in contact. Individual cylinders have the property that when rotated to zero degrees they show a surface with an emissivity of one and when rotated to 180 degrees display a surface with an emissivity of zero. At intermediate angles of rotation a sensor that could resolve individual cylinders would see alternate lines with high and low emittance but a sensor unable to resolve individual cylinders sees a surface with an emittance that depends on the angle the cylinders are rotated. Variable emittance surfaces are expected to be useful for controlling target signature and for making spectral reflectivity measurements using a hyper-spectral radiometer.

The apparatus having an aperture at least n times as big as A centered on the optical axis of the lens to admit a collimated relay beam including the central beam and a diverter means for separating the relay beam into n collimated facet beams equal to the central beam, but exclusive thereof, and redirecting them through the lens aperture to produce n additional images on the same focal plane. The apparatus also including a processor with a separate opto-electronic device for each image that converts it between electronic and photonic states, the electronic images being stored in the processor.

Abstract: An apparatus and technique for sensor signal to noise ratio enhancement obtained by co-adding multiple identical images on an electro-optical sensor focal plane. An apparatus and technique for multiple laser source projection onto a target by use of laser diode arrays which are collimated and then diverted to simultaneously illuminate a target.

Abstract: A magnetically activated switch includes a flexible metallic strip on the inside of a sealed encasement, having first and second ends. The first end provides for an electrical contact and extends through the wall of the sealed encasement, with the strip being firmly secured by the wall of the encasement at the exit point, leaving the second end unsupported and having a magnetic responsive element attached. A first dipole magnet is coupled to the flexible metallic strip and located within the sealed encasement, intermediate the first and second ends. Second and third dipole magnets are diametrically opposed and separate to each other where each of the second and third dipole magnets are fixedly coupled to the inside surface of the sealed encasement. Two electrical terminals coupled respectively to the second and third dipole magnets extending through the sealed encasement.

Abstract: A releasable securing knob assembly including a biased leaf spring element hich securely locks a knob onto a shaft, so that removal can only be effected by accessing and debiasing the leaf spring through a slot within the knob.

Abstract: A device and technique for the passive real-time control of effective emivity, color, and camouflage, the device utilizing surfaces which are interposed between a target and an observer at a viewing position with a predetermined angular resolution. Effective surfaces are utilized, including at least one set of movable surfaces, the effected surfaces having a predetermined surface characteristic, such as emissivity, color, or camouflage pattern. An assembly contains all surfaces relative to each other such that the front and back surfaces are seen by the viewing position as stationary. A drive assembly allows movable surfaces to move.

Abstract: A safety system and technique for multi-aperture optical systems such as TOW missile system that protects against the inadvertent activation of system function and warning the user that the system function is not ready for activation. The electrical trigger for the TOW missile system sends a signal to the firing circuits to launch a TOW missile. A micro-switch is mounted on the barrel of the near infrared (IR) tracker optical system fore optics, activated by the presence of a lens cap. A light group including a green and red light is included in the visible optical system of the TOW missile system. If the lens cap is off, then a green light is visible and firing circuits may be activated by a trigger. If the lens cap was inadvertently left on near IR tracking fore optics then a red light is visible and no voltage flows to the firing circuit when the trigger is depressed.

Abstract: An analog computer method provides modulation transfer functions (MTF) expressions or graphs for arbitrary shaped detectors in an arbitrary scan direction. Fraunhofer diffraction calculations or measurements given for specific shaped apertures are used for calculating detector MTFs of similarly shaped detectors. In an analog measuring device, an aperture in an opaque screen may be made the shape of a detector whose MTF is to be calculated. The aperture is flooded with laser light which produces a Fraunhofer irradiance pattern at an observing screen which is parallel with the opaque screen, for measuring the irradiance in the Fraunhofer plane at the observing screen. A sensor, which has a detector small compared with the diffraction pattern, is moved along the chosen thermal imager scan direction, in the Fraunhofer plane.
