Abstract
A system and method for transmission of a signal for a powered assistive device has a sensor node with a wireless transmitter adapted for digitally transmitting a transmitted signal, the sensor node adapted for receiving and monitoring a sensor signal from a sensor attached to a user, and a master node with a controller and a wireless receiver for receiving the transmitted signal from the wireless transmitter. The master node processes the transmitted signal and communicates a control signal to the powered assistive device. The wireless transmitter transmits the transmitted signal at a first rate when the wireless transmitter adapted to transmit the transmitted signal at a first rate when the sensor signal is indicative of the rest state and to transmit the transmitted signal at a second rate when the sensor signal is indicative of the active state, the second rate being greater than the first rate.
