Abstract
A system determines the movement of a track vehicle along the ground, the track vehicle having at least a first rotatable, endless track for supporting the vehicle on the ground, a drive for causing the movement of the vehicle, and a turning system for changing the direction of the movement of the vehicle. The system has a first traction-improvement device for mounting on the track vehicle. It bears on an inner-surface side of the first track with sufficient pressure for a small-surface portion on the opposite side of the first track to engage the ground with a higher pressure than any other portion of the first track, whereby to locate a pivoting axis of the track vehicle in the vicinity thereof. A first speed sensor for mounting on the track vehicle in the vicinity of the small-surface portion on the opposite side of the first track senses the speed of movement of the track vehicle along the ground only in the direction of the rotation of the first track and provides a first information thereof, whereby the movement of the track vehicle may be deduced therefrom. Preferably the vehicle has two tracks, and the system has two such traction-improvement devices and speed sensors respectively for the two tracks.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
