    • A method and apparatus are set forth for defining and validating feature policies in an execution system, such as a communication system. The method includes entering user policies described in a straightforward manner (e.g. using a Web browser and user-understandable language) in such a way that they can be translated into a formal executable language. The user policies are then translated into an executable feature language such as the IETF's CPL. The user is then either compelled or provided with an option to validate the overall feature set before it is uploaded to the execution system. If validation is selected, the features are translated from CPL into another format, such as FIAT, from which it is possible to detect common feature specification errors. The FIAT detected errors are then analyzed in a manner that is aware of the expectations and common errors of naïve users, and interpreted to determine possible errors as errors that are common to naïve users. These errors are reported to the user (e.g. via the Web interface) in terms that are understandable to naïve users and compatible with how the policies were originally described. The user is provided with options to either accept the interactions as they are, repair them manually or to accept a recommendation of an automatic correction. Unlike conventional systems, where feature interactions are solved in the same way for all users, the selected resolution is personalized in the present invention to satisfy the end-user's intentions, independently of how others solve similar conflicts. The features are uploaded to the execution system.
    • 使用Web浏览器界面接收用户输入的策略。 这些政策被转化为呼叫处理语言(CPL),并进一步转化为功能交互分析工具(FIAT)。 分析策略之间的错误,并通过Web界面向用户报告。 在上传到通信系统之前,向用户提供了接受互动或进行更正的选项。 还包括以下独立权利要求:(1)用户策略配置设备; 和(2)计算机程序产品,包括存储基于web的用户策略管理程序的记录介质。

    • An embedded loudspeaker system is set forth incorporating at least two asymmetric enclosures having different but overlapping frequency responses in order to achieve a substantially flat frequency response. At least one of the speaker enclosures is preferably ported (bass-reflex system) to provide as much output as possible in the low-frequency range. By using a plurality of speakers at least one of which has a bass reflex enclosure, a monophonic system is provided with a flat frequency response. The dimensions of the speaker enclosures are chosen such that the anti-resonance of one loudspeaker enclosure is compensated for by the resonance of another speaker enclosure, without making use of damping, so that no "notch" appears in the frequency response of the combined system at the listening position
    • 提出了一种嵌入式扬声器系统,其包括具有不同但重叠的频率响应的至少两个非对称外壳,以实现基本上平坦的频率响应。 扬声器外壳中的至少一个优选地被插入(低音反射系统),以在低频范围内提供尽可能多的输出。 通过使用多个扬声器,其中至少一个扬声器具有低音反射外壳,单声道系统具有平坦的频率响应。 扬声器外壳的尺寸被选择为使得一个扬声器外壳的反共振由另一个扬声器外壳的谐振补偿,而不利用阻尼,使得组合系统的频率响应中不会出现“陷波” 在听力位置
