摘要:
The present invention circumvents inherent inefficiencies of photosynthesis by exposing chloroplast (or equivalents thereof) to light in a periodic manner during the organisms' “daylight” cycle. Optical, electro-optical, and/or electromechanical techniques are introduced to conventional farming methods to increase the conversion efficiency and farming yield many-fold. A module is provided that carries out the above benefits. The module includes: a solar distribution sub-system; and a structure having a plurality of growing levels configured and dimensioned to support a desired quantity of plant life and associated nutrient sources (e.g., soil, hydroponic, or an equivalent nutrient source).

A system and method for converting an analog voltage signal to a digital representation at high speeds, known as an analog to digital converter (A/D converter), is provided. The invention teaches an N-bit A/D converter, made by N superconducting, preferably HTC, transmission lines. The N lines are arranged adjacently and in parallel with each other. On each line 2N−1 JJs are imbedded in series. The JJs form a matrix over the configuration of the N superconducting transmission lines in such a manner that across the lines the JJs give N digit binary numbers, while in the length direction these N digit binary numbers fall in numerical order. A scanning electron beam is made to impinge on this arrangement. The beam is scanned across the lines at a high frequency, while it is deflected by the applied voltage signal along the direction of the lines. The beam generates a voltage step on any one of the N lines on condition of hitting any one of the JJs. In this manner upon each cross-scanning of the beam, an N-bit step voltage pattern is generated on the lines. This pattern is the direct digital readout of the input voltage signal.

An oxygen enrichment system is provided. The system includes an electrochemical cell for generating oxygen from ambient air. The electrochemical cell extracts oxygen from ambient air based on hydroxide conduction. A mixer is provided in fluid communication with ambient air, and an outlet provides oxygen enriched air to a user or air-breathing apparatus. In further embodiments, a purification system is also included. The air enrichment system may be employed with suitable batteries to provide a portable air enrichment device.

A light controlling film is described comprising a polymerized polymer network of a crosslinked high molecular weight polymeric material and a low molecular weight cholesteric liquid crystal (CLC) material, wherein the high molecular weight and the low molecular weight form a material having cholesteric liquid crystal (CLC) order such that the film is a reflective circular polarizer whose bandwidth is controllable by an electric field impressed in the film.

A multi-mode stereoscopic imaging system is described. It is the first stereo system which is convertible back and forth from the auto stereo viewing mode without glasses to the binocular stereo viewing mode with glasses. It is based on micro-polarizer arrays and spatial multiplexing of images. The system consists of a stereo image component and an auto parallax barrier component. Both components use the properties of &mgr;Pols. Switching from one mode to the other is accomplished manually, and electronically with the aid of a liquid crystal light valve. The system combines the benefits of auto-stereo imaging and the binocular stereo imaging of prior art techniques without their limitations.

Probes and methods of making probes are provided, particularly probes or nano-tools having tip active areas of extremely small dimensions, e.g., on the order of one angstrom to a few nanometers. One method of making a nano-tool includes forming a composite including a tool layer less than 10 nm thick on a substrate layer, subtracting a region of the substrate layer at least partially through the thickness of the substrate layer, thereby exposing a well surface, and folding the composite so that portions of the tool layer surface diverge and portions of the well surface converge, wherein an outer crease of the folded tool layer is a nanotool active area. Another method of making a nano-tool includes forming a composite including a tool layer less than 10 nm thick on a substrate, subtracting a region of the substrate layer at least partially through the thickness of the substrate layer, thereby exposing a well surface, and folding the composite so that portions of the tool layer surface diverge and portions of the well surface converge, wherein an outer crease of the folded tool layer is a nanotool active area, whereby the tip may be cut mechanically or altered to expose two probe active areas. The herein probes may be very useful in systems and methods that benefit from probes having resolution capabilities less than the dimensions of the objects to be analyzed.
