An edge emitting semiconductor laser comprising an active, radiation-generating zone, and an common waveguide, which is suitable for guiding the radiation generated in the active zone within the semiconductor laser. Additionally, various embodiments of the invention include methods of manufacturing a customizable shoe based upon pressure scanning the feet of a particular user. The data file is distributed to a second end user who uses the data that represent the route in a second computing system to provide guidance for following the route. At least one damaged-enhanced image is then rendered for display of the newly formed 3D polygon mesh from a field of view of the user of the interactive computer simulation. In this method of the invention, the first cryptographic engine performs its tasks independently of the second cryptographic engine. According to the invention, the information representative of the angular position that is used is a mean of the angular positions sensed by the at least two angular position sensors.
