Abstract: A monitoring device for obtaining data from a patient during a respiratory and/or cardiac cycle of the patient. The monitoring device includes a compliant variable capacitor securely attached to the patient. The capacitance of the compliant variable capacitor changes during movement of the patient caused by the respiratory cycle and/or a cardiac cycle. The changing capacitance is used to generate a monitoring signal that includes the frequency, timing and amplitude of either the respiratory or cardiac cycle. The signal from the monitoring device is provided to a medical imaging system such that the medical imaging system can compensate for the motion of the patient during the reparatory/cardiac cycle.

Abstract: A method for controlling a pitch control system of a wind turbine includes providing a charged backup battery configured to supply no energy to a DC link when full AC input power is available, wherein the DC link includes a DC link capacitor. The method further includes using energy stored in the DC link capacitor to operate a pitch control system during a loss or dip of AC input power, and maintaining charge on the DC link capacitor using the charged backup battery as voltage across the DC link capacitor drops during the operation of the pitch control system.

The method includes electrically coupling n batteries to form a string of batteries, electrically coupling n battery charger assemblies to the n batteries such that each respective battery charger assembly is coupled to an anode and a cathode of a respective battery, and charging the plurality of batteries utilizing the n battery charger assemblies.

Abstract: A rotor for a wind turbine generator includes a rotatable hub forming a cavity. A plurality of rotor blades is connected to the hub. A heat sink is at least partially positioned within the cavity and extends along a portion of a corresponding rotor blade. The heat sink includes a bottom surface mounted on a thermal energy generating component of the wind turbine generator. An opposing top planar surface includes a plurality of pins extending therefrom. The pins form an air flow path through the pins to dissipate the generated thermal energy from the thermal energy generating component.
