| 20090151476 | TORQUE MEASUREMENT METHOD AND APPARATUS - A torque measurement device associated with a power driven ground engaging device having a power supplying device and a load. The torque measurement device includes a rotatable shaft, a first detectable feature, a second detectable feature, a plurality of sensors and an electrical controller. The rotatable shaft has a longitudinal axis, a first end and a second end. The first end is connected to the power supplying device and the second end is connected to the load. The first and second detectable features are respectively associated with a first longitudinal position and a second longitudinal position on the shaft. The plurality of sensors include a first sensor and a second sensor. The first sensor is proximate to the first detectable feature and the second sensor is proximate to the second detectable feature. The first sensor produces a first signal and the second sensor produces a second signal as the rotatable shaft rotates about the longitudinal axis. The electrical controller samples the first signal and the second signal at a sampling rate. The first signal has a first frequency and the sampling rate is less than twice the first frequency. The electrical controller computes a torque measurement representative of the torque on the rotatable shaft utilizing the first signal and the second signal. | 06-18-2009 |
