Title: Rotating signal transducer

Abstract: A wireless rotating signal transducer. A control circuit is provided for transferring power and communication signals through a wireless coupling device in a vehicle steering column. A squib firing circuit transforms a high energy power signal suitable for firing an air-bag from the column side to the wheel side. A low-energy power circuit generates a signal from the column side to the wheel side suitable for operating isolated wheel side electronics, such as cruise control and the like. A pulse-encoder circuit communicates low-level control signals suitable for signaling wheel-side commands from the wheel side to the column side. The low-energy power circuit and pulse encoder circuit operate simultaneously and continuously without signal debilitating interaction.
