Abstract
Apparatus and method for transmitting condition data from a rotating member to a stationary device is disclosed wherein digitized data obtained from a plurality of sensors is transmitted from the rotating member to the stationary device through a system of light emitting diodes on the rotating member which flash light signals in a preselected digital sequence. The data so obtained is received by a system of stationary receivers, and thereafter decoded and processed for utilization. Electric power for the rotating components is obtained by using the kinetic energy of the rotating member.
