1. Packaging, including:
- a wall to extend around and enclose contents to be contained in the packaging;
a group of electrically-conductive tracks extending over the wall, each including a first end and a second end opposite to the first end; and
an electronic control circuit secured to the wall and including a group of first, output ports and a second, input port, the output ports being connected to respective ones of the first ends of the electrically-conductive tracks and the input port being connected to the second ends of the electrically-conductive tracks;
wherein the electronic control circuit is operative to output electrical pulses from each of the output ports, with the pulses output from each of the output ports being distinguished from one another, and responsive to absence of receipt of pulses from any of the output ports via the electrically-conductive tracks to provide an indication of occurrence of damage to the wall.

Abstract
A construction of packaging such as an envelope is disclosed that comprises a wall surrounding contents of the packaging and electrically conductive tracks extending over the wall. An electronic control device is mounted to the wall and includes a plurality of output ports to which one end of each conductive track is connected and an input port to which an opposite end of the conductive tracks are connected. The control device outputs from the output ports pulses which are distinguished from one another and monitors the input port for receipt of these pulses to provide an indication of integrity of the wall of the package.

13. A blank, comprising:
-
a sheet of paper or cardboard bearing a group of electrically-conductive tracks extending over the sheet, each including a first end and a second end opposite the first end; and
an electronic control circuit secured to the sheet and including a group of first, output ports and a second, input port, the output ports being connected to respective ones of the first ends of the electrically-conductive tracks and the input port being connected to the second ends of the electrically-conductive tracks;
wherein the electronic control circuit is operative to output electrical pulses from each of the output ports, with the pulses output from each of the output ports being distinguished from one another, and responsive to absence of receipt of pulses from any of the output ports via the electrically-conductive tracks to provide an indication of occurrence of damage to the sheet.
