Patent number: 10760937Abstract: A system includes a container having an inner chamber for storing fluid, at least one measuring probe arranged within the chamber and one ground probe arranged within or near a bottom of the chamber. There is at least one impedance electrically connected with a processor which is electrically connected with the at least one measuring probe. A signal generator has a first voltage terminal electrically connected with the at least one impedance and a second voltage terminal electrically connected with the ground probe. When a signal is sent from the signal generator to the measuring probe, an electrochemical reaction occurs at the measuring probe and ground probe and stores a charge if the measuring probe and/or ground probe are immersed in fluid.

Patent number: 10753829Abstract: A non-contact aerodynamic sampling tool for collecting particles and vapors from the surfaces. Opposing planar jets or planar jet arrays are used to liberate material from surfaces so that particulate matter and vapors can be collected for analysis in real time. High-speed valves may be triggered to create pressure waveforms for high velocity pressurized planar jet bursts, or continuously operated opposing wall jets may be angularly directed toward a target surface, permitting sampling from large standoff distances. The wall jets traverse the surface and exhibit significant drag forces to lift particles into a suction intake. Unlike axisymmetric jets, the wall jets sustain the flow momentum over the target surface for a greater distance, dislodging particles submerged in the boundary layer and significantly improving particle resuspension and vapor collection.Type: GrantFiled: March 17, 2019Date of Patent: August 25, 2020Assignee: SpecTree, LLCInventor: Igor V Novosselov
