MOTION CAPTURE APPARATUS
First Claim
1. A motion capture apparatus comprising a first 3-dimensional accelerometer, which can output a signal relative to its angular orientation, a second 3-dimensional accelerometer which can output a signal relative to its angular orientation, a processor for processing the angular orientation signals of the accelerometers and for determining the relative angle between the first and second accelerometers.

Abstract
A motion capture apparatus (10) comprises a series of sensor nodes (12) connected to a transceiver hub. Each node (12) comprises a 3D accelerometer (20), a (3) axis gyroscope array 21a, b and a microprocessor (29) on one side of a double-sided PCB (18). A vibration transducer (31) is arranged on the other side of the PCB (18). A controller receives sensed data from multiple nodes enabling the relative angle between nodes to be determined periodically. The controller multiplexes between receiving sensed data from the node and activating/deactivating the transducer (31) to give the impression of simultaneous sensing and vibration without the vibration affecting the sensed data.
