A system for powering components in a vehicle seat enables electronic components within the vehicle seat to receive power without wires connecting the seat to a vehicle body. The system includes a power transmitter that generates an electromagnetic field, and a power receiver located within the vehicle seat and the electromagnetic field. The power receiver is configured to generate electrical power from the electromagnetic field and deliver the power to at least one component in the vehicle seat.

Contactless power transfer system

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.

Method for robust wireless wind turbine condition monitoring

A method of wirelessly transmitting alarm signals includes wirelessly transmitting an alarm signal from a transmitting station. It is determined whether an acknowledgement signal wirelessly transmitted from an access point in response to the access point receiving the alarm signal has been received by the transmitting station. A relaying station is woken up and kept awake during a plurality of periodic time intervals for overhearing transmissions from the transmitting station. If it is determined that an acknowledgement signal from the access point has not been received by the transmitting station, then the alarm signal is wirelessly re-transmitting from the transmitting station during at least one of the time intervals in which the relaying station is awake. The alarm signal is received at the relaying station. The alarm signal is transmitted from the relaying station to the access point.
