The document destruction capsule is connected to the monitor, and as the result of the monitoring process is capable of destroying the documents by colouring them. The circuit comprises at least one pair of windings (9,10) which are so built into the casing that any damage to the latter produces a situation alteration. The windings are fitted between inner (7) and outer (13) walls of the casing, and are laid tightly alongside one another that together they form a surface layer which encompasses the whole inner wall.$The windings are positioned irregularly inside the surface layer so those of like and different voltages locate against one another in a random fashion.$USE/ADVANTAGE - To protect valuable documents being carried in a portable device.(2) |
