The device that uses multiple wavelengths (colors) of light and/or multiple species of gas to independently measure the distortions imposed on an optical cavity, cell, or other optical element that holds gas due to the forces applied by said gas. The device measures differences between index of...

The invention is a flow meter that measures convection/diffusion of an activated compound (e.g. a marker) between an activation point and a measurement point i n a liquid flowing through a microchannel (Figure 1). The compound (e.g. caged fluorescein) in the flow is activated when it crosses an...

This invention is a spectroscopic method that adjusts the incident light intensity as a function of wavelength to flatten the solvent-only transmitted light spectrum over an interesting wavelength range. When a solvent has a strong absorption band within an interesting spectral region of analytes,...

The device is able to load a material or joint in pure shear, and measure the strength, elastic modulus and shear to failure. It can characterize the exact mode of loading during the duration of the test, and is able to apply a mixed Mode I/II loading if desired. It is applicable for testing the...

The invention is a probing instrument that can recover a signal (normally a signal would be a 3D environment such as a room, a building, a city, etc.) by illuminating the signal with electromagnetic radiation structured in space and time according to the excitation signals applied to the...

The invention is a method for fabricating millimeter-scale and sub-millimeter calls containing a vapor of alkali atoms in large numbers at the wafer scale. The key element of the method is that the wafer that forms the glass lid of the cell is translated laterally between the alkali deposition step...
