摘要： A sensor circuit enables detection of DC offset in a sensor output signal. The sensor circuit includes a sensor that generates a sensor output signal corresponding to a physical signal coupled to an input of the sensor, and a modulator that generates a modulation signal, the modulator being coupled to the sensor to modulate a physical parameter of the sensor and to enable a DC offset to be separated from the sensor output signal. To enable the circuit to measure the DC offset even though the sensor output signal is inversely proportional to the output signal, the circuit includes a feedback circuit configured to generate a feedback signal. The feedback signal is coupled to the input of the sensor to enable the physical parameter of the sensor to be modulated without modulating a portion of the sensor output signal attributable to the physical signal being converted to an electrical signal by the sensor.

摘要： A method of operating a wind turbine includes providing a wind turbine having a plurality of blades. A respective sensor is attached to each of the blades. First measurements of a structural characteristic of each of the blades are repeatedly taken by use of the sensors. A tolerance band is established for the measurements. Signals indicative of the first measurements are wirelessly transmitted only if the first measurements are outside of the tolerance band. The transmitted signals are received at a controller. An actuator signal is sent from the controller to at least one actuator associated with the blades. The sending is in response to the receiving of the transmitted signals. At least one of the blades is actuated dependent upon the actuator signal. The actuating is performed by the at least one actuator. Second measurements of the structural characteristic of each of the blades are repeatedly taken by use of the sensors after the actuating step. The wirelessly transmitting, receiving, sending and actuating steps are repeated for the second measurements.
