A temperature sensor capable of taking contact method temperature measurements in extreme temperature environments includes a heterogenous ceramic fiber formed of two materials having different compositions, the heterogenous fiber including a junction between the first and second materials.

Embeddable ultrahigh temperature sensors and method for making

A low power mass spectrometer assembly includes at least an ionization component, an electrostatic analyzer, a lens assembly, a magnet assembly and at least one detector located in a same plane as the entrance to the magnet assembly for detecting the deflected sample ions and/or fragments of sample ions, including ions or ion fragments indicative of the Vitamin D metabolite within the sample.

A system and process scans a target area at a distance of 3-30 m for one or more materials. Scanning is performed by a coherent transmit beam aimed with the help of a thermal camera. The active source of the beam is a supercontinuum (SC) laser. The transmitted source beam is modulated by a high-speed Fourier-transform spectrometer prior to interaction with the target. Target reflected source beam is detected by an infrared detector, along with a reference portion of the transmitted source beam, as a series of interferograms; passed through a digitizer for digitizing the interferograms; and processed to producing spectrograms, wherein the spectrograms are indicative of one or more materials on the target.

A low power mass spectrometer (LPMS) includes an ionization source for generating an ionized sample beam; ion focusing optics for focusing the sample beam; and a static magnetic field region contained within an electric field-free drift region created between magnets acting as equipotential electrodes combined with a third equipotential surrounding electrode for receiving the focused sample beam and deflecting ions therein to different points on a detector array in accordance with an individual mass thereof. The LPMS operates at less than 1.2 Watts and has a physical footprint equal to or less than 12 inches at its largest length.
