摘要： A wind turbine condition monitoring system and method are disclosed where the wind turbines include a tower, a gearbox coupled to the tower, and turbine blades coupled to the gearbox. The monitoring system includes blade sensors coupled to the blades, a hub node coupled to the gearbox and a controller. The controller is in communication with the hub node and blade sensors, and determines blade positions based on blade sensor readings. The blade sensors and hub node can include multi-axis accelerometers. The controller can wirelessly communicate with the blade sensors directly or through the hub node. Using position information, shadowing areas with obstructed communication can be avoided, node separation can be accounted for to reduce power requirements and/or interference from multiple transmitters can be avoided during node communications.

摘要： An automotive communication method includes installing a sensor within a vehicle such that the sensor is submerged in a liquid during operation of the vehicle and/or substantially surrounded by a metallic structure during operation of the vehicle. A long wave magnetic signal is transmitted from the sensor. The signal is indicative of a condition sensed by the sensor. The signal is wirelessly received at a controller disposed within the vehicle. Receipt of the signal at the controller is responded to by adjusting a display and/or a setting within the vehicle.

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.
