Abstract: Systems and methods for efficient coupling to low-loss eigenmodes of a spherical waveguide bounded by the Earth's surface and its ionosphere from multiple locations within the waveguide are disclosed. One or more eigenmodes of the Earth-ionosphere waveguide may be computed based on a mathematical model incorporating electrical properties of the terrestrial surface and plasma physics of the ionospheric layer. Multiple wave guide couplers, each including an array of electrically-connected waveguide-coupling elements, may be configured at different geographic locations for coupling to the one or more eigenmodes. By adjusting relative phases and/or amplitudes of the waveguide couplers, as well as frequencies, power may be coupled into standing waves of the Earth-ionosphere waveguide. The adjustments may also account or compensate for diurnal variations of ionosphere by steering power nodes and nulls of the standing waves away from regions of potential ohmic losses.

Abstract: A data processing system is configured to sense a pressure readings of an air-mattress. If the pressure readings are below a target pressure value representing a desired pressure for the air-mattress, the data processing system can transmit, to an air-pump, first instructions to increase the air pressure of the air mattress and determine a replacement value representing the amount of air pumped into the air mattress by the air-pump. The data processing system can compare the replacement value to a slow-leak threshold and to a catastrophic-leak threshold. The data processing system can, responsive to a determination that the replacement value is greater than the slow-leak value and less than the catastrophic-leak value, transmit, to the air-pump, second instructions to increase the air pressure of the air mattress to replace air in the air mattress lost to a slow leak so as to maintain the desired pressure for the air-mattress.

Abstract: A crossover protection system including a product transport vehicle having a tank compartment for containing a liquid product, a fluid property sensor positioned to contact liquid product stored in the tank compartment, a system controller, and a valve coupled to the tank compartment. The valve regulates a flow of liquid product from the tank compartment and has a normally locked state. The system controller may compare a received transported liquid type signal from the fuel property sensor indicative of the type of liquid product in the tank compartment and compare the type of liquid product to a stored liquid product type. If the two types match, the crossover protection controller transitions the valve to an unlocked state to allow the liquid product to unload from the tank compartment. If the two types do not match, the crossover protection controller will disable the valve from transitioning to the unlocked state.
