Abstract: Disclosed is a system that provides a common application software interface for a variety of vendor supplied license servers. The system provides a single set of program calls and translates this single set of calls into a set of calls for each license server. This translation is performed using a translate table, which is easily updated to interface to newly developed or newly released license servers. The system runs as a separate process within the operating environment to monitor the application program, and as long as the application program continues to provide services to the user, the system sends periodic license renewal messages to the license server. The system also notifies the user when the application program cannot obtain a license in order to provide a consistent user interface across applications.

Abstract: A loudspeaker system is provided wherein the coils, capacitors, and loudspeaker drive units and combinations thereof are resistively damped to provide electrical damping of the back EMF of these components and thereby reduce ringing in the loudspeaker crossover networks. The result is a measurable and clearly audible improvement in the accuracy of the sound produced by the loudspeaker system.

Abstract: A loudspeaker system is provided wherein sound absorptive foam material is affixed to the sides of the loudspeaker cabinet so as to absorb that portion of the sound radiated from the loudspeaker that is directed towards the rear of the loudspeaker system, thereby serving in eliminating sound reflections from the walls of the room. This results in an overall system which can more accurately reproduce the recording site ambience inherent in a recording and which permits more accurate and natural imaging, i.e., more precise localization of voice and instrument placement within the soundfield of a pair of stereo loudspeakers.
