摘要： This disclosure describes systems, methods, and apparatus for remotely monitoring an elevation, or change in elevation, of a fluid surface, such as that of molten sapphire. The remote monitoring can be performed by measuring positions of a pair of reflected laser beams off the fluid surface as detected on an imaging sensor. As the surface elevation falls, the positions of the pair of reflected laser beams move relative to each other, and this positional change can be converted into a change in the fluid surface elevation.

摘要： Measurement devices are mounted on left and right steerable wheels of a vehicle. Caster is calculated for each of the wheels based upon measurements made with the measurement devices. Pitch at zero toe is determined for the left and right wheels and a steering axis inclination (SAI) compensation term is determined. Live caster is calculated using the live pitch of the wheel, the caster calculated for the wheel, the pitch at zero toe for the wheel and the SAI compensation term. An output representative of the live caster is provided.
