    Abstract: The disclosure relates to aqueous compositions which comprise water soluble fluorinated surfactant, fluorinated synergist, ionic non-fluorochemical surfactant, nonionic non-fluorochemical surfactant, electrolyte, and solvent. This composition is a concentrate which when diluted with water spreads on fuel surfaces suppressing vaporization. Because of this property the aqueous solutions of the above compositions are effective as agents for fire fighting.

    Abstract: An angular reflectance sensor having no moving parts and capable of the essentially simultaneous measurement of the reflectivity of a surface at a plurality of angles. The sensor comprises a quarter pitch graded index lens (78) having first end face (82) and second end face (84) and an optical axis (86). Light is coupled from an optical source (72) to an input position (88) on the first end face. A plurality of detectors are provided, each detector having associated therewith an output position (97-99) on the first end face. Each detector comprises a photodetector (74-76) and a fiber optic cable (94-96) for coupling light from the associated output position to the photodetector. The second end face of the lens is positioned adjacent a surface. Light reflected from the surface at a particular angle is focused by the lens to a particular output position, and thus to a particular photodetector.

    Abstract: An arrangement for optical multiplexing and demultiplexing. The multiplexer comprises an optical output waveguide and a plurality of optical input waveguides coupled to the output waveguide by nonblocking optical switches. An electrical activation signal at a switch causes light entering the switch through the associated input waveguide to appear on the output waveguide. The activation signals are provided by a pulse traveling down an electrode past the optical switches, such that parallel input signals on the input waveguides are time multiplexed onto the output waveguide to produce a serial output signal. A similar arrangement is provided for a demultiplexer comprising one input waveguide and a plurality of output waveguides.

    Abstract: An apparatus is provided for use in determining the distance and velocity of a distant object. The apparatus employs a low energy optical radiation source that emits identical external and internal radiation signals whose wavelengths are swept. The wavelength sweep is induced by varying the magnitude of an electrical input supplied to the optical radiation source. An external ranging system employs common optical means, including polarizing means, to direct the external signal towards a distant object, and to receive a portion of that signal which reflects off of the object. First optical heterodyne means are provided to mix the reflected external signal and a local oscillator signal derived from the external optical radiation signal, to produce an output signal. Means are provided to determine representative values of the frequency of that output signal. An internal processing system directs the internal signal into an optical delay means of a known length. Upon exiting the optical delay means, the delayed internal signal is received by a second optical heterodyne means and mixed therein with a local oscillator signal derived from the internal optical radiation signal. Means are provided to determine a representative value of the frequency of the output signal from the second optical heterodyne means. Additional means are provided to determine the central frequency of the external and internal optical radiation signals. Finally, processor means utilize the representative frequency values derived from the external ranging system and internal processing system, and the central frequency value, to calculate the distance and velocity of the distant object.
