    摘要： A method for estimating two or three location coordinates and/or receiver time offset for a receiver that receives and analyzes timed signals transmitted from one, two or three non-geosynchronous satellites (GPS, GLONASS, modified LEO, etc.). Combinations of pseudorange, Doppler shift and/or first time derivative and/or second time derivative of Doppler shift are determined and used to estimate the location coordinates and/or receiver time offset.

    摘要： A non-alcoholic effervescent compound for cleaning and disinfecting the mouth, teeth, gums and breath without necessity of alcohol as a solvent. Surface acting agents, or surfactants, are used to reduce surface tension of the compound in solution, facilitating dissolution of all additives including non-soluble oil-containing components. Surface acting agents also produce a foaming effect which loosens bacteria and food off and out from between teeth. The compound eliminates use of alcohol as a solvent, has increased cleaning action from both foaming and effervescence and produces a good-tasting, desirable mouthwash with appropriate flavor concentrations.

    摘要： An unobscured three mirror wide-angle telescopic imaging system comprised of an input baffle which provides a 20.degree. (Y axis).times.30.degree. (X axis) field of view, a primary mirror having a convex spherical surface, a secondary mirror having a concave ellipsoidal reflecting surface, a tertiary mirror having a concave spherical reflecting surface. The mirrors comprise mirror elements which are offset segments of parent mirrors whose axes and vertices commonly lie on the system's optical axis. An iris diaphragm forming an aperture stop is located between the secondary and tertiary mirror with its center also being coincident with the optical axis and being further located at the beam waist of input light beams reflected from the primary and secondary mirror surfaces. At the system focus following the tertiary mirror is located a flat detector which may be, for example, a TV imaging tube or a photographic film. When desirable, a spectral transmission filter is placed in front of the detector in close proximity thereto.
