Abstract: We describe a computing machine, called a quantum random, self-modifiable computer, that uses self-modification and randomness to enhance the computating power. Sometimes it is called an ex-machine, derived from the latin extra machinam because its can evolve as it computes so that its complexity increases without an upper bound. In an embodiment, an ex-machine program can compute languages that a Turing or standard machine cannot compute. In an embodiment, the ex-machine has three types of instructions: standard instructions, meta instructions and random instructions. In an embodiment, the meta instruction self-modify the machine as it is executing so that new instructions are added. In an embodiment, the standard instructions are expressed in the C programming language or a hardware description language such as VHDL. Random instructions take random measurements from a random source. In an embodiment, the random source produces quantum events which are measured during the machine's execution.

Abstract: A three-dimensional component is produced in a simplified molding operation. Expandable substrates, which are referred to as blanks, are created by compressing thermobonded nonwovens after heating the binder material above its melting temperature, and then cooling the compressed nonwovens so that the binder material hardens and holds the fibers of the nonwoven together in a compressed configuration with stored kinetic energy. Boards can be formed by laminating two or more blanks together and/or by laminating the blanks with other materials, including non-expendable materials. A mold for the component to be manufactured can be partially filled with a number of boards (or blanks) in a stacked, vertically, adjacent or even random orientation. In addition, the boards or blanks may be cut to create desired shapes of parts that can be placed in the mold.
