The present invention allocates the supply of critical components and manufacturing capacity by optimizing critical material planning decisions and dynamically allocating constrained materials using advanced substitution logic that considers alternate suppliers and supports product life cycle from design through end-of-life. Existing applications programs written with a dynamically linked library or object library, with no speech recognition capability, are capable of accepting input from a speech recognition without modification. The device is designed using a method and system that applies sequential pressure to regions on a plantar foot surface, and obtaining positional information about each region. Laser factors also vary depending from the thickness of the powder layer, type of metallic powder and size and size distribution of the powder particles. Also disclosed is an apparatus for controlling usage times for at least one device.
