Abstract
A control system is provided having stationary check points which are contactlessly read by a data collector and verified. The data so read can be stored and transmitted by a transmitter to a central unit, where the data so received are centrally evaluated. Together with the data of the check point being read, the time at which the respective check point is read is transmitted to the central unit as well. If all data are received by the central unit, it transmits back a verification entry, and the data are subsequently stored in a memory together with such verification entry. If no verification entry is received, the data are automatically and continually retransmitted to the central unit until the verification entry is received by the receiver in the data collector. In addition, the data collector has a random generator capable of establishing which individual check points are to be successively called on by the security guard. Each check point is to be called on within a time range and, if such time limit is exceeded, an emergency call is automatically transmitted to the central unit.

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.
