Abstract: An active infra-red surveillance illuminator uses a statistically mono-directional micro-diffractive material overlaid on a bank of light emitting diodes (LEDs) to refract light from the LEDs onto a target image. This delivers energy distribution profiles out to a distance to match the aspect ratios of current wide-angle target and wide-angle camera surveillance systems. The distribution of refracted light is elliptical. This distribution can vary by using different diffractive material in conjunction with various numbers, brightness and angles of the LEDs in an LED bank. The effective range of the illuminators is greatly extended with this type of illumination. By limiting infrared (IR) radiation down to a 10 degree vertical window it renders the IR illumination much more effective for surveillance imaging by providing much more effective power on wide, ground-level scenes, and particularly enables multi-lane license plate capture.

Abstract: An oven using radiant heat at infrared wavelengths optimized for producing rapid and uniform cooking of a wide variety of foods. The infrared oven toasts, bakes, broils, and reheats food at a much faster speed while maintaining high quality in taste and appearance of the cooked food. Optimal infrared wavelengths of the radiant heat sources are used for the best balance of cooking performance, while also reducing the time required to cook the food. Typically short to medium wavelength infrared radiant energy will result in good performance for toasting and browning of food. Medium to long wavelength infrared radiant energy is well suited for delivering more deeply penetrating radiant energy into the food. This deep penetration of radiant infrared heat energy results in a more thorough internal cooking of the food than with conventional methods of conduction and convection cooking.
