G10K 11/00 G10L 21/00
US Classification:
367198, 704275, 704E21001
Abstract:
A device controller configured to control physical devices using an audible humming frequency that includes: a humming frequency module, a humming command module, and a control command module. The humming frequency module may be configured to determine humming frequenc(ies) using a detected humming signal(s). The humming command module may be configured to compute humming command(s) based on the humming frequenc(ies). The control command module may be configured to generate control command(s) using received key command(s) and humming command(s).

International Classification:
C02F 1/48 C02F 1/00
Abstract:
Resources, such as water, energy, power, amount of de-scaling chemicals, device lifetimes, data analytics and system depreciation may be conserved through the use of dual-field electric and magnetic probes that create and apply electromagnetic fields to liquids, such as water.
Methods And Devices For Treating Radionuclides In A Liquid
- Bethesda MD, US Patrick J. Hughes - Vienna VA, US Hossein Ghaffari Nik - Fairfax VA, US Akrem Hassen Adem Aberra - Fairfax VA, US Richard B. McMurray - Fairfax VA, US Shelley Marie Grandy - Fairfax VA, US
Assignee:
Reverse Ionizer Systems, LLC - Bethesda MD
International Classification:
G21F 9/10
Abstract:
Radionuclides and other unwanted material in a liquid may be treated, removed or reduced through the use of electromagnetic fields applied to the liquid by electrodes that also function as co-precipitators by leaching polyvalent metal ions into the liquid.
