Utility
Low power mass analyzer and system integrating same for chemical analysis
4 May 21
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.

Utility
Deep ocean long range underwater navigation algorithm (UNA) for determining the geographic position of underwater vehicles
23 Mar 21
An underwater navigation algorithm (UNA) uses acoustic signals transmitted in the ocean from sources at known positions to compute a position underwater for a vehicle that requires no initial a priori position or any ocean sound speed information or any initial GPS position that would require surfacing.
