Abstract: A defined vehicle path emulator system is described, which system can be used for measuring the F-min values and profiles for a path on a concrete floor traversed by a vehicle with a specific wheelbase. The defined vehicle path emulator is an autonomous robot that guides itself down the selected path. The F-min values are used to calculate the deviations away from zero planar infinity while traversing the path for a tall mast carried by an emulated vehicle. This invention's systems are distinct from the (FF/FL) floor flatness and floor levelness measuring systems in the literature as prior art. The floor can be marked for deviations from flatness by means of a laser etching system activated by the emulator's software system. The emulator can also signal an operator when it detects itself veering off of the defined path.

Abstract: An improved mechanism for grinding surfaces flat is presented, involving a precision grinder with grinding heads that are adjustable in a vertical dimension controlled by a support structure on wheels. The support structure has an adjustable wheelbase that allows sinusoidal flaws in a surface to be ground down in a controllable way. The device can be used in coordination with floor flatness measurement devices to grind concrete floors, and other horizontal surfaces.

Abstract: A defined vehicle path emulator system is described, which system is used for measuring the (Fmin) specification for a path on a concrete floor traversed by a vehicle with a specific wheel base. The (Fmin) system is in use to locate and report the magnitude deviations away from zero planar infinity while traversing the path of a tall vehicle. This invention and system is distinct from the (FF/FL) measuring machines in the literature.
