Failure inducive operating conditions of an X-ray generator tube are sensed. Some of the sensed operating conditions are events such as hot overload of the target and thermal shock of the target, while other sensed operating conditions include hot target bearing use and thermionic cathode filament heater use. Certain of the sensed operating conditions are integrated, with the integrated output being compared against a predetermined standard to yield a prediction of remaining operating life. Other sensed conditions, if present, are indicative of incipient failure without integration. The integrated signals are stored in electrochemical cells and read out periodically for a prediction of incipient tube failure.

A multipli-layered tamper-proof wrap consisting of a number of over-layed thin plastic sheets bonded around the outer edge to contain one or a number of chemical layers therein, appropriately separated, whose penetration or puncture will result in a visual indication at the puncture, and including distinct seals fixed at spaced intervals to the outer or external wrap sheet that indicate wrap or product origin and are to discourage wrap substitution. The wrap is for encapsulating a consumer product so as to provide a continuous wrap surface therearound that will give a visual indication of a breach in wrap integrity at a point of penetration or puncture.
