The invention provides computer-enabled methods and systems for the secure transmission and platform-independent receipt and decryption of encrypted messages. Through the use of a computer system integrated with automatic individual animal identification multiple measurement and remeasurement systems with automatic data input and a cattle handling and sorting system, animals are individually identified and measured by weight, external dimensions and characteristics of internal body tissue. The regions, for example, may comprise lines of weakness extending between the semiconductor devices and may be formed by localized thinning of the substrate or by treating the substrate material to modify its stiffness at predetermined areas. There is a hole with internal screw threads in the top of each cone, into which a large bolt-like contacting member is screwed.
