摘要： 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.
摘要翻译： 公开了一种为各种供应商提供的许可证服务器提供通用应用软件接口的系统。 该系统提供单个程序调用集，并将该单个呼叫转换为每个许可证服务器的一组呼叫。 该翻译使用翻译表执行，翻译表可以轻松更新，以便与新开发的或新发布的许可证服务器进行交互。 该系统作为操作环境中的单独进程运行，以监视应用程序，只要应用程序继续向用户提供服务，系统会向许可证服务器发送定期的许可证更新消息。 系统还通知用户何时应用程序无法获取许可证，以便跨应用程序提供一致的用户界面。

摘要： 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.

摘要： 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.
摘要翻译： 提供了一种扬声器系统，其中吸声泡沫材料固定在扬声器机柜的侧面，以便吸收从扬声器辐射的声音朝向扬声器系统后部的那部分声音，从而消除了从扬声器 房间的墙壁。 这导致整个系统能够更准确地再现记录中固有的记录站点环境，并且允许更准确和自然的成像，即在一对立体声扬声器的声场内的语音和仪器放置的更精确的定位。
