摘要:
A method of operating a camera with a microfluidic lens to identify a depth of an object in image data generated by the camera has been developed. The camera generates an image with the object in focus, and a second image with the object out of focus. An image processor generates a plurality of blurred images from image data of the focused image, and identifies blur parameters that correspond to the object in the second image. The depth of the object from the camera is identified with reference to the blur parameters.

A method is provided for making “smart” paper and “smart” microfibers by means of nanotechnology layer-by-layer techniques. The method comprises forming an aqueous pulp of lignocellulose fibers and nanocoating it by alternatively adsorbing onto the fibers multiple consecutively-applied layers of organized ultra thin and oppositely-charged polyelectrolytes, at least one of which is an electrically conductive polymer or nanoparticle (or a magnetically active polymer or nanoparticle, or an optically active polymer or nanoparticle), and another one of which has a charge opposite of said electrically conductive polymer or nanoparticle (or magnetically active polymer or nanoparticle, or optically active polymer or nanoparticle), thereby making a modified aqueous pulp of electrically conductive (or magnetically active, or optically active) multi-layer nanocoated lignocellulose fibers; then draining the water out of the modified aqueous pulp to form sheets of smart microfibers. A finished paper is manufactured by drying the sheets of the nanocoated multi-layer fibers and processing the dried sheets to make a smart paper having enhanced electrical conductivity, magnetic and/or optical properties.

A solar cell. The solar cell includes a substrate, a first layer comprising a first copper-based material deposited upon the substrate, the first copper-based material electrically attracted to the substrate or to a first optional deposit layer deposited between the substrate and the first layer, and a second layer comprising a second copper-based material deposited upon the first layer or an second optional deposit layer deposited between the first layer and the second layer, the second copper-based material electrically attracted to the first layer or to the second optional deposit layer, wherein the first copper-based material and the second copper-based material are selected from the group consisting of copper indium gallium (di)selenide (CIGS), copper indium selenium (CIS), and cadmium sulfate (CdS).
摘要:
A method of imaging biological tissue enables imaging structure in the biological tissue with an antenna tuned to emit radio energy through at least a covering layer of the biological tissue without significant attenuation of the radio energy. The method includes contacting skin covering tissue with a radio frequency emitting antenna, and adjusting at least one of a radiator and a feed in the antenna with reference to at least one measured electrical or physical property of the skin. The adjustment of the radiator and feed enable a combination of the antenna and skin to emit radio energy at a predetermined magnitude and frequency into a portion of the tissue covered by the skin.

摘要:
A chipless RFID tag system having a transmitter sending an input signal and a tag substrate. An ID generation circuit on the tag relies on microstrip transmission line patterns which are pre-designed to generate a unique code. The ID generating circuit may be designed based upon the transmission line properties, including signal delay, and/or reflection, and/or phase change. The tag may be formed on a flexible substrate having at least one microstrip and the microstrip having a first portion with a first impedance and a second portion with a second impedance different from the first impedance. The tag may further include a microstrip antenna for communication with the transmitter and a receiver system. The tag may also include sensors for detection of desired substances of interest. The system may further include a receiver detecting at least two reflections from an interface of first and second impedances and identifying relative time domain positions of the reflections to one another.
