Classification: CPC B  G | IPC B  G

Claim 0:
1. A mixer vehicle comprising:
a mixer drum;
a first accelerometer and a second accelerometer, wherein the first accelerometer is configured to produce baseline acceleration signals and the second accelerometer is configured to measure accelerations within the mixer drum to produce disturbed acceleration signals; and
a controller configured to:
obtain the baseline acceleration signals and the disturbed acceleration signals from the first accelerometer and the second accelerometer as the mixer drum rotates;
determine an amount of noise in the disturbed acceleration signals relative to the baseline acceleration signals based on a comparison between the baseline acceleration signals and the disturbed acceleration signals; and
use the amount of noise in the disturbed acceleration signals to determine a presence of material and one or more properties of the material within the mixer drum.
