Abstract: An automatic washing device includes a plurality of fluidic oscillators arranged on the periphery of a rotating drum. The fluidic oscillators emit a pulsatile stream of fluid at a predetermined angle through a slit that is perpendicular or at an angle to a longitudinal axis of the oscillator. The automatic washing device can remove microorganisms from the pliant epidermal surface of a human hand that comprises brushlessly scrubbing the pliant epidermal surface of the human hand with a plurality of cleansing fluids.

Abstract: The invention is a solid state microanemometer and a method of making thereof. Specifically, the invention relates to a microanemometer including an electrically conductive resistor in the form of a semiconductor wafer doped with an impurity having an upper surface, a lower surface having a peripheral edge; a substrate bonded to the semiconductor wafer having an upper surface, a cavity having a peripheral edge and a peripheral margin defined on the upper surface and bounded by the peripheral edge of the cavity wherein the lower surface of the semiconductor wafer rests on and is supported by at least part of the peripheral edge of the cavity such that the semiconductor wafer is over the cavity; and a means for electrically connecting the resistor to a current source. The microanemometer also includes a plurality of metal conductors in contact with the resistor.

Abstract: Optical processing apparatus for processing a stream of light. The apparatus includes a light input emitted, for example, by fiber optic cable. Multiple wavelength bands of light are, typically, emitted and transmitted in a direction parallel to an axis. The apparatus also includes a plurality of receptors which are positioned at defined locations spaced from one another. A diffracting member is employed to diffract the wavelength bands of light transmitted parallel to the axis. In one embodiment of the invention, the diffracting member is a controllable diffraction grating. The wavelength bands are selectively diffracted to various of the receptors. The apparatus further includes a controller for selectively adjusting the diffracting member to independently vary a particular receptor to which any one wavelength band is diffracted.
