Turbo-Cycle Rotor Engine

An engine with a very low part count, high power density, and flexibility to operate with a constant pressure burn for high efficiency is in the concept stage. It is optimizable for power, efficiency, and high power density; and is non-idling, self-starting, self-lubricating, and with regenerative braking. Fuel is introduced with the compression entering the combustion chamber. The amount and timing of the charge can be delivered in efficient pulses or in a nearly constant pressure mode for high power. Each sweep of a plate accomplishes two of the cycles. Three of the six plates exchange exhaust with fresh air as they sweep a chamber ahead of the power stroke. The other three drive plates expand combustion gases and compress the fresh air ahead of it into the central accumulator.

Technique Measures Material Properties

Developed for quality control and wafer metrology in the semiconductor manufacturing market, this non-destructive technology may be highly adaptable to measuring material properties such as a coating’s thickness, thermal and electrical conductivity, and material imperfections. The technology uses two overlapping lasers to measure the thickness of metal on a substrate using the metal’s known heat conductivity and reflectivity. Depending on the metal, thicknesses from 5 μm down to 100 Angstroms can be measured. The technology is sensitive to residues and extremely fine contaminants. Voids, breaks, bridges, or connections between fine metal lines can be detected. If there is a known differential in thermal conductivity between the surface metal deposition and its substrate, metal thickness can be deduced. The nominal laser spot size is 3 μm; measurements may be made to within approximately 20 μm from the edge of a work piece.

Diagnostic and Sorting Technologies

This non-invasive technology enables accurate plant quality assessments before any physiological change is perceived by the naked eye. Plants, and plant parts, can be assessed at any stage of growth. The technology is based on chlorophyll fluorescence, highly correlated to desired plant qualities. Stems, leaves, fruits, berries, and ears may be assessed — the technology is useful in the hothouse, field, or grocery store. Any plant with chlorophyll can be tested for seed vigor, germination, good growth, and freshness. Impacts from drought, herbicides, and insects are easily detectable long before becoming visible. Screening spot measurements can be done, or more general measurements performed, with an imaging detector on an area roughly 1 x 1.5 m.
