    摘要： Abrasion testing, and hence particle content of fluids including liquids and gases is carried out by abrading a thin film 25 of an electrical conductor with the fluid, and measuring the resulting change in electrical resistance of the film.The method can be used to monitor metal particles in oil, and hence the state of wear of oil-lubricated metal parts, and the level of particulate pollution in the atmosphere.

    摘要： Various embodiments of the present invention are directed to a photodiode module including a structure configured to selectively couple light to a dielectric-surface mode of a photonic crystal of the photodiode module. In one embodiment of the present invention, a photodiode module includes a semiconductor structure having a p-region and an n-region. The photodiode module further includes a photonic crystal having a surface positioned adjacent to the semiconductor structure. A diffraction grating of the photodiode module may be positioned and configured to selectively couple light incident on the diffraction grating to a dielectric-surface mode associated with the surface of the photonic crystal. In another embodiment of the present invention, a photodiode apparatus includes multiple, stacked photodiode modules, each of which is configured to selectively absorb light at a selected wavelength or range of wavelengths.

    摘要： An optical resonator configured to be tuned using a charge-based memory cell includes an optical cavity configured to transmit light and receive injected charge carriers; a charge-based memory cell in proximity to or within the optical cavity, the memory cell containing a number of trapped charges which influence the resonant optical frequency of the optical resonator. A method of tuning an optical resonator includes applying a voltage or current to a charge-based memory cell to generate a non-volatile charge within the memory cell, the nonvolatile charge changing a resonant frequency of the optical resonator.

    摘要： A mold with a protruding pattern is provided that is pressed into a thin polymer film via an imprinting process. Controlled connections between nanowires and microwires and other lithographically-made elements of electronic circuitry are provided. An imprint stamp is configured to form arrays of approximately parallel nanowires which have (1) micro dimensions in the X direction, (2) nano dimensions and nano spacing in the Y direction, and three or more distinct heights in the Z direction. The stamp thus formed can be used to connect specific individual nanowires to specific microscopic regions of microscopic wires or pads. The protruding pattern in the mold creates recesses in the thin polymer film, so the polymer layer acquires the reverse of the pattern on the mold. After the mold is removed, the film is processed such that the polymer pattern can be transferred on a metal/semiconductor pattern on the substrate.
