Claim 14:
15. A system comprising:
a fixed circuit board having a primary coil, wherein the fixed circuit board includes an inductive coupling circuit having the primary coil, a data filter, and a capacitor, wherein the data filter is electrically connected to and between the capacitor and the primary coil;
a rotatable circuit board having a secondary coil, the rotatable circuit board has a circular perimeter and a portion of the secondary coil is embedded within the rotatable circuit board and is adjacent to the circular perimeter, the rotatable circuit being configured to rotate about an axis;
a sensor being in communication with the secondary coil of the rotatable circuit board, wherein the sensor is located remotely from the rotating circuit board and is configured to rotate about the axis;
a wired connection between the sensor and the rotating circuit board;
the primary coil of the fixed circuit board being inductively coupled to the secondary coil, wherein the primary coil provides power and receives data from the sensor when inductively coupled to the secondary coil; and
wherein the inductive coupling circuit utilizes a modulation scheme such that a window of valid data sent by the rotating circuit board is a fixed constant phase in relation to power generated from the fixed circuit board, wherein a width of the window is based on a presence of a pulse of contained in a period of a sinewave allowing serial data to be sent from the rotating circuit board to the fixed circuit board at a constant phase.
