  • Patent number: 11177677
    Abstract: The system is directed to enhancing the energy efficiency of electrical charging systems. The system is utilized in circuits that include a power source such as a battery feeding electrical current into an energy storage device such as a capacitor to charge the capacitor with electrical power. The system of the invention extracts energy from such circuits that would otherwise be converted into heat and thereby wasted. The system includes an energy storage and release device such as a motor that is connected to the circuit and converts the electrical energy therein that would otherwise be converted into heat into mechanical energy or electrical energy by means of monitoring and controlling electrical current flow through the system to maintain it at low and constant levels.

  • Patent number: 8895834
    Abstract: An assembly is disclosed for adjusting the position of a solar array or device to enable it to maintain a desired solar energy reception throughout each day's operation of the assembly. Solar panels are mounted on a first axle and a second axle, and the axles are mutually orthogonal. The assembly also includes a first motor for rotating the array and the panels relative to the first axle in a direction providing azimuth angle position adjustment and a second motor for rotating the array and the panels and the second axle in a direction providing elevation angle position adjustment. The motors are electrically connected to and powered by their respective solar panels.

  • Patent number: 7893346
    Abstract: An integrated voltaic energy system incorporates a bio-friendly DC power generator with a photovoltaic (PV) system connected to feed a main service panel and a utility grid. A plurality of inverters are connected one each, to a respective output of one of a plurality of photovoltaic (PV) solar arrays. The outputs of each of the inverters are connected to a main service panel and a utility grid. A further inverter is connected to the DC power generator and in parallel with the other inverters. The DC power generator is also connected to each of the PV solar panel inverters through a switch operated at a specific time manually or automatically. When switched the DC power generator feeds all of the inverters. A resistor/capacitor structure is connected between the DC power generator and each inverter. A self-powered timer may control the output level of the DC power generator.

  • Patent number: 7412015
    Abstract: Methods and apparatus for separating desired signals from a mixed signal. A preferred method includes identifying the frequencies associated with the independent signals within the mixed signal and sampling the mixed signal once for each of the identified frequencies. Using the identified frequencies, a set of constant coefficients is determined and applied to the samples to separate at least one of the independent signals from the mixed signal. The other independent signals may then be suppressed. A signal processing system is also supplied that includes memory and a circuit. The memory stores samples of the mixed signal for the circuit to process. The circuit identifies the frequencies of the independent signals, determines a set of coefficients, and applies the coefficients to the mixed signal. Thus, the system separates a desired signal from the mixed signal.

  • Patent number: 6904374
    Abstract: Methods and systems for predicting electromagnetic scattering are disclosed. In one embodiment, a method includes covering at least a portion of an analytical model of a target with computational cells, and formulating a plurality of approximation functions. The formulating of the approximation functions includes simplifying a set of method of moments equations based on Kirchhoff's first law to provide an impedance matrix multiplied by a solution vector equated with a right hand side vector. A plurality of boundary conditions are established for the plurality of approximation functions, and the plurality of approximation functions are solved for the solution vector. The impedance matrix is deflated by a sparse transformation determined by the geometry of the scatterer, independent of material properties and frequency, subsequently reducing the computational complexity of the scattering calculation.

  • Patent number: 5590031
    Abstract: A system is disclosed for converting high frequency zero point electromagnetic radiation energy to electrical energy. The system includes a pair of dielectric structures which are positioned proximal to each other and which receive incident zero point electromagnetic radiation. The volumetric sizes of the structures are selected so that they resonate at a frequency of the incident radiation. The volumetric sizes of the structures are also slightly different so that the secondary radiation emitted therefrom at resonance interfere with each other producing a beat frequency radiation which is at a much lower frequency than that of the incident radiation and which is amenable to conversion to electrical energy. An antenna receives the beat frequency radiation. The beat frequency radiation from the antenna is transmitted to a converter via a conductor or waveguide and converted to electrical energy having a desired voltage and waveform.

  • Patent number: 5483169
    Abstract: A non-destructive test system that displays time domain amplitude returns from multi-frequency, multi-phase, constant magnitude RF signals, that are reflected by differences in characteristic impedance of a wire over ground plane transmission line. The reflections are used to detect RF discontinuities or faults in conductive areas that form the ground plane which preferably are resolved using a generalized pencil-of-points algorithm. The nondestructive testing system so constructed is especially useful in testing field repairs of radar absorbing material (RAM) and other features of a conductive object or vehicle whose radar return is to be minimized.
