Abstract: An energy absorption device absorbs energy that is released upon impact between two objects in relative motion. An exceptional load applied to any of the two objects results in acceleration of one object relative to the other object. The acceleration energy is absorbed by deformation of an element or elements that are put under stress from the objects upon impact. The process of deformation includes a controlled diameter reduction during a forced elongation of a semi-solid or solid deformation bolt made from a cold-formed material in the direction of force generated from the acceleration.

Abstract: An energy absorption device (3) and method is disclosed for absorption of energy that is released upon impact between two objects in relative motion, wherein an exceptional load applied to any of the two objects results in acceleration of said object relative to the other object, and wherein for retardation of said acceleration energy is absorbed in the process of deformation of an element or elements which are put under stress from the objects upon impact. The process of deformation comprises a controlled diameter reduction during a forced elongation of a semi-solid or solid deformation bolt (4) made of cold-forming material in the direction of force (FX) generated in said acceleration.

Abstract: A method of starting a computer program where the program is stored in a memory belonging to a computer on which the program is to be used by a user. A first part of the program is stored in a primary memory of the computer in a first method step, wherein the first program part is the entire program with the exception of a smaller second part thereof. The primary memory requires the application of a voltage in order to retain information. The second part of the program is fetched from a source other than the source of the first part of the program in a second method step. The second part of the program is stored in the primary memory in a third method step, whereupon the program is complete and ready for use.
