摘要： A self aligning microbend sensor comprises a tubular housing having internal threads, an expandable insert with external threads loosely threaded into the housing with sufficient tolerance to allow expansion of the insert in response to a parameter being measured while maintaining registration of the threads, and a fiber optic element between the housing and the insert and extending transverse to the threads, such that upon expansion of the insert the fiber optic element experiences microbending due to deformation by the threads.

摘要： A method of determining the compression ratio of a cylinder of an internal combustion engine. While the engine is being driven by a prime mover a PV curve is developed which is stored in the memory of a microprocessor. The unswept volume of the cylinder is determined by trying various values of unswept volume in the function PV.sup.n =C and determining which value of unswept volume causes the curve developed by this function to best fit the stored curve. Compression ratio is determined after the unswept volume is determined.

摘要： Magnetic and dielectric properties of a sample are determined by measuring the microwave absorption of the sample. A cavity containing the sample material is coupled to a microwave source and the radiation propagated to the cavity is modulated at a reference frequency. A microphone coupled to the cavity senses the pressure fluctuations resulting from the thermal changes generated in the sample by the absorption of the modulated microwaves and the microphone signal is analyzed at the reference frequency to provide an electrical output which is a measure of the microwave absorption by the sample material. Both dielectric and magnetic properties of the sample can be measured.

摘要： The invention introduces the concept of very low cost, fully integrated, large scale planar polymer light guide networks. These networks are intended primarily for automotive applications, including data communication, multiplex, sensor, switch and display networks. However, the concept is also applicable in other areas where the length of the network does not exceed a few meters. The basic idea is to `cut` a thin sheet of clear plastic (polymethylmetacrylate polycarbonate, or polystyrene) into a whole network consisting of optical links, couplers, sensors, etc. . . . In addition to being low cost, planar polymer light guide networks extend the one dimensional geometry of fiber optics into two dimensions, adding tremendous design capability and versatility.

摘要： A microbend fiber optic pressure sensor includes a short length of sensing fiber comprising a fiber of a transparent dielectric material surrounded by a layer of aluminum or similar metal for which the real part of the complex permittivity is negative over a range of electromagnetic radiation wavelengths. The layer of aluminum is hermetically sealed to the transparent material. The sensing fiber receives light in the range of wavelengths and is subjected to microbends on the dielectric/aluminum boundary by pressure responsive mechanical apparatus for a much greater microbend light loss and therefore greater sensitivity than is obtained with similar sensors using an all glass core/cladding boundary. The sensing fiber may be an aluminum coated single mode fiber with a very small core and a large cladding layer in which the cladding modes are used and the core modes ignored or it may comprise a single glass fiber coated with aluminum. The sensing fiber is used only in the sensing region, with light coupled to one end from a light source and from the other end to a light detector through lower loss multimode optic fibers.
