    • A horn loudspeaker comprises: a horn (22) having a throat (26) and a mouth (30); a primary electro-acoustic driver (24) mounted at or adjacent the throat of the horn and directed generally along the horn; and at least one secondary electro-acoustic driver (32T, 32B, 32L, 32R) mounted part-way along the horn and directed generally across the horn. The secondary driver(s) can be used to change the local impedance conditions in the horn and therefore to change the polar response of the horn loudspeaker. At least one filter (12A, 12E) is provided for filtering an input signal (34) for the primary driver to produce a filtered signal for the primary driver or each of the secondary drivers. Such a filter may be chosen or designed so as to optimize some aspect of the polar response of the horn loudspeaker, for example to increase directivity, or flatten the polar response within a specified included radiation angle, or to increase omnidirectionality.
    • 喇叭扬声器包括:具有喉部(26)和嘴(30)的喇叭(22); 主电声驱动器(24),其安装在喇叭喉部处或邻近喇叭的喉部处,并且大致沿着喇叭被引导; 以及至少一个辅助电声驱动器(32T,32B,32L,32R),其沿着喇叭安装并且大体上穿过喇叭。 辅助驱动器可以用于改变喇叭中的局部阻抗条件,并因此改变喇叭扬声器的极性响应。 提供至少一个滤波器(12A,12E),用于过滤用于主驱动器的输入信号(34),以产生用于主驱动器或每个次驱动器的滤波信号。 可以选择或设计这种滤波器,以便优化喇叭扬声器的极性响应的某些方面,例如以增加方向性,或者在特定的包含的辐射角内平坦化极坐标响应,或增加全方位性。

    • A building curtain wall panel system is disclosed in which a plurality of mechanically fastened and bonded layers are provided to create a fire resistant, light weight and insulated panel which is easily installed and yet resists impact stress. The panel includes bonded layers attached to a steel frame. The strength and fire resistant properties are enhanced by a medium density calcium silicate composite panel. The exterior architectural design features may be varied by composite coatings including a variety of materials including acrylic resins, fibers, vicron, fungicide, coloring agents, cement and water.

    • A method and system comprises integrating a contest framework into a game. The contest framework at least comprises means for communicating with a transactional server, a plurality of listeners being configured to monitor interactions during a play of the game for communication to the transactional server, and means for displaying notifications from the transactional server. The transactional server is at least configured for processing received interactions in conjunction with a progressive jackpot contest associated with the game and communicating notifications regarding the processing to the contest framework. A communicating with the transactional server at least comprises associating the game with a progressive jackpot contest and setting parameters for the progressive jackpot contest.
    • 一种方法和系统包括将比赛框架整合到游戏中。 比赛框架至少包括用于与事务性服务器进行通信的装置,多个收听者被配置为在游戏中向交易服务器通信期间监视交互,以及用于显示来自事务性服务器的通知的装置。 交易服务器至少被配置为结合与游戏相关联的渐进累积奖金竞赛来处理接收到的交互,并且将关于处理的通知通知给比赛框架。 与交易服务器通信至少包括将游戏与累进累积奖金比赛相关联,并为渐进累积奖金比赛设置参数。
