Patent ID: 8913042

Claim:
A stylus comprising: a body; a shaft disposed within the body and having a tip-end that protrudes from the body and an interior-end located within the body; a transverse support through which the shaft passes and on the shaft is cantilevered and/or pivoted, the transverse support located between the tip-end and the interior end of the shaft; a compliant element configured to support the tip-end of the shaft; a multi-axis force sensor in contact with the interior-end of the shaft and operable to sense lateral and longitudinal forces applied to the tip-end of the shaft, the multi-axis force sensor comprising at least three sensing elements each in contact with a convex surface of the interior-end of the shaft; a signal combiner circuit operable to combine signals output from the at least three sensing elements to produce a representation of the lateral and longitudinal forces applied to the tip end of the stylus; and a transmitter operable to transmit the representation of the lateral and longitudinal forces over a communication link to a host electronic device.
