Abstract
A method of determining and displaying during operation an actual degree of soil compaction achieved with a soil compacting device includes the steps of driving the soil compaction device with a motor and compacting the soil with the soil compacting device. The motor is secured against surpassing a predetermined maximum rpm limit by providing a protective rpm limiting circuit. The ignition impulse is delayed with the protective rpm limiting circuit, when the predetermined maximum rpm limit is surpassed. Within a time interval the average of the delay of the ignition impulse is determined as a base value for a display value of the actual degree of compaction. For a large surface area to be compacted it is possible to compact the soil within a test portion to the desired degree of compaction and save the corresponding display value as a reference value to be used during compaction of the remaining portions.

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.
