Abstract

A method and apparatus to provide evidence that a person who is intended to make a required inspection was actually physically present at a predefined location associated with the inspection, so that the inspection could have been done, and if not, to provide an indication of the failure to perform the inspection. This invention is particularly well suited to determine if required pre/post-trip inspections of vehicles have been performed. Detecting a triggering condition, such as powering on (or off) equipment, indicates the beginning of a period of time during which the inspection is to be performed. The monitoring system waits for a predetermined event to occur, which indicates the period of time has expired and determines if data corresponding to the inspection have been received. If not, it is concluded that the inspection has not been performed.

Claims

(a) detecting a triggering condition, the triggering condition indicating at least one of the following;

(i) the vehicle is about to start at least a segment of a trip; and

(ii) the vehicle has completed at least the segment of the trip;

(b) after the triggering condition has been detected, transmitting a signal indicating that a person has been disposed proximate to at least one predefined location associated with the vehicle, while nominally conducting at least one of the pre-trip inspection and the post-trip inspection of the vehicle;

(c) receiving the signal at a monitor that is not part of the vehicle, thereby enabling a person who is not disposed proximate to the vehicle to verify that the required inspection was performed; and

(d) determining whether the signal has been received at the monitor before a predefined event occurs, and if not, determining that the person cannot yet have completed the at least one of the pre-trip inspection and the post-trip inspection of the vehicle, wherein if it is determined that the person cannot have completed the at least one of the pre-trip inspection and the post-trip inspection of the vehicle, performing at least one of the following functions;
