A solar array power generation system includes a solar array electrically connected to a control system. The solar array has a plurality of solar modules, each module having at least one DC / DC converter for converting the raw panel output to an optimized high voltage, low current output. In a further embodiment, each DC / DC converter requires a signal to enable power output of the solar modules.

A wind turbine is presented where the operation lifetime of the main bearing is extended by relieving the main bearing by reducing the mean bending moment on the bearing by means of individual pitch control of the blades of the rotor so as to create an aerodynamic mean tilt moment on the rotor by means of aerodynamic forces on the blades, the tilt moment at least partly counteracting the bending moment caused by the overhang load forces on the main bearing from the gravitational pull on the rotor mass.

An automatic tuning system for a magnetic field generating tuned circuit includes a processor configured to maintain the resonant frequency of a tuned circuit equal to a reference frequency. The tuned circuit is driven by a power amplifier whose output provides an amplified signal at the reference frequency. The tuned circuit includes a magnetic field generating inductor and a bank of individually switchable capacitors controlled by the processor capable of adding and removing the respective capacitances to and from the tuned circuit. The inductor includes a Faraday shield to shield the tuned circuit from the influence of electric fields. In an embodiment of the invention, the variable capacitor is in the form of a diode variable capacitor (varicap) in parallel circuit relationship with the tuned circuit capacitor and the inductor. In an alternate embodiment the inductor and a fixed capacitor are in series circuit relationship with the varicap in parallel circuit relationship with the fixed capacitor and the tuning sequence relies on a phase locked loop using the phase of a reference frequency signal and the phase of the inductor voltage as control parameters.

A distortion compensation system minimizes distortion in an audio system by monitoring a supply voltage and adjusting a clipping threshold and / or compression knee. An adjustable gain circuit controls the gain of the audio signal according whether the audio signal exceeds a variable threshold. The variable threshold is adjusted within a threshold range based on the supply voltage. Distortion due to clipping of the audio signal is minimized while available power at any given time is maximized.

Metallic workpieces of diverse shapes having work surfaces which are deformed at the surface and adjacent sub-surface layers by surface impact from ultrasonic transducers employing freely axially moving impacting elements propelled and energized by a transducer oscillating surface vibrating periodically at an ultrasonic frequency. The impacting elements are propelled in a random aperiodic and controlled impact mode at different phases of the periodic oscillation cycles. The transducer may be portable and provides a series of mechanically interconnected stages having mechanical resonances harmonically related as a multiple of the primary ultrasonic frequency and have matched stage resistances under instantaneous loading when the impact elements are driven by the transducer oscillating surface into the surface of the workpiece. This mode of operation produces Q-factor amplification of the input ultrasonic power oscillator energy at the impact needles and high propulsion velocities making it possible to machine metallic workpiece bodies to greater depths for compressing the metal to increase compressive strength of the workpiece work surfaces to substantially the ultimate material strength. The impact machining is done at ambient temperatures.

A method for combining beams from multiple laser emitters, which may be optical fibers or bulk amplifiers, to form a composite output beam with desirable beam characteristics, as measured, for example, by Strehl ratio. Beams from the multiple emitters are interferometrically combined in the near field, and the phases of the beams are controlled to provide optimal phase coherence, and thereby to minimize losses. Various techniques are disclosed for controlling the phase angles of the emitted beams, using either a separate phase detector for each emitter beam, or a single detector for the composite output beam, or nulling detectors in spurious outputs from the beam combining optics. All of these techniques achieve an improvement in Strehl, largely because the interferometric combination of beams is independent of the array fill factor.

The present invention is directed to an apparatus and method for improving the total power output from a field of solar energy systems. The invention provides a field level tracker controller which calculates an improved positioning of individual solar energy systems and communicates those configurations to trackers in the field. An algorithm stored in the controller calculates the improved configuration for the solar energy systems based on factors such as solar movement, shade patterns generated by surrounding structures, and measured output of the energy systems. Improved positioning may include individual energy systems being directed to a stowed position to maximize the power output of the field as a whole.

System and method for providing a programmable power supply. The programmable power supply may include a programmable hardware element (PHE) that couples to a power supply (DC-DC converter) and which in turn couples to a linear regulator. The PHE may implement a PID control algorithm that receives a measurement of the output power and may use PID and / or non-linear control to ensure that the power supply and the linear regulator maintain similar power levels. The PHE may be configured based on a graphical program, thus enabling fast and efficient modifications to the programmable power supply.

A method of deploying offshore wind turbine assemblies includes mounting a wind turbine assembly horizontally on a vessel and transporting the wind turbine assembly to an offshore site. The wind turbine assembly is raised to a vertical condition at the site and attached to anchor weights. Blades are attached to the turbine head after the wind turbine assembly is in the vertical condition. In one embodiment, the wind turbine assembly can include a tower including tapered lower and upper sections joined together at their respective wide ends, a turbine head connected to the upper section, and a platform connected to the lower section. The platform includes a buoy tank partially filled with ballast to provide mass and buoyancy. A wave piercing cowling is rotatively attached to the lower section. The turbine head can include an adjustable journal bearing, scabbard blade mounts, and a gearless induction generator with flux adjusting capabilities.
