Abstract: An events-monitoring and recording system for providing at any desired time a tangible record of a large number of several kinds of different events that have occurred randomly over an extended period of time, and in the case of each event further providing an accurate record of the date and time of day at which the individual event occurred. The data of the events are immediately produced and stored for future access as the events occur, without involving any moving mechanisms and with recording of each change of time from AM to PM and from one day to the next, whereby the system is capable of operating faultlessly in extremely adverse environments subject to vibration, heat, cold, particulate and gaseous pollutants and without attention over extended periods of time.
