Programming language constructs called pronouns and referents, and a method, system, and apparatus for translating computer source code that contains the pronouns and referents. The present invention may use an acoustic sensor to detect Korotkoff sounds indicating incipient blood flow past the tourniquet. The partition plate is installed in the casing. When necessary, external appliances are used for the transmission of data to andor from the stimulator and for the transmission of power, if necessary. The system and method further allows creation of various versions of the 3D object from a single production process.
