    • A compact smoke alarm assembly (10) is disclosed. The assembly (10) comprises: a smoke detection chamber (20) defined by a body (22) having a plurality of openings for allowing airflow therethrough, the body (22) having a sound inlet aperture (25); a smoke detector (30) mounted to the body for communication within the chamber (20); an electrical circuit operatively connected to the smoke detector (30), the circuit providing an electrical signal when the smoke detector (30) detects smoke in the chamber (20); and a piezoelectric disc (40) mounted external to the chamber adjacent to the sound inlet aperture, the piezo disc (40) operable in response to the electrical signal to generate sound. The smoke detection chamber (20) is sized substantially in accordance to the Helmholtz formula to cause resonance at the operating frequency of the piezo disc (40).
    • 公开了一种小型烟雾报警组件(10)。 组件(10)包括:由主体(22)限定的烟雾检测室(20),该烟雾检测室具有多个用于允许气流通过的开口,所述主体(22)具有声音入口孔(25); 烟雾探测器(30),安装到所述主体以在所述腔室(20)内连通; 所述电路可操作地连接到所述烟雾探测器(30),所述电路在所述烟雾探测器(30)检测所述腔室(20)中的烟雾时提供电信号; 以及安装在与所述声音入口孔相邻的所述腔室外部的压电盘(40),所述压电盘(40)响应于所述电信号而可操作以产生声音。 烟雾检测室(20)的尺寸基本上按照亥姆霍兹(Helmholtz)公式,以在压电盘(40)的工作频率下引起共振。

    • A formatting object according to the present invention conveys information to the reader of a document (such as a table or chart) by associating visual attributes (such as color, fill type, border width, line width, line style, font size, marker size and marker type) to characters or markers within the document. The formatting object may be used to emphasize data within a table or a chart by modifying the structural visual attributes of characters or markers within the table or chart according to pre-defined criteria. Similarly, the formatting object may be used to increase information density within a table or chart, and to elegantly represent the relationships between four or more interrelated variables in a two-dimensional chart. The formatting object accomplishes this by defining at least one format map that comprises one or more mapping segments. Each mapping segment includes a beginning boundary value, an ending boundary value, at least one beginning visual attribute corresponding to the beginning boundary value, and at least one ending visual attribute corresponding to the ending boundary value. The formatting object uses the information within the format maps, in combination with interpolation techniques, to determine one or more visual attributes that correspond to data points falling within the various mapping segments. The formatting object then expresses the data values by applying the appropriate visual attribute to a visual object displayed on a computer screen.
    • 根据本发明的格式化对象通过将视觉属性(诸如颜色,填充类型,边界宽度,线宽,线型,字体大小,标记尺寸等)相关联来向读者传达信息给读者(例如表或图表) 和标记类型)到文档中的字符或标记。 格式化对象可以用于通过根据预定义的标准修改表或图表中的字符或标记的结构视觉属性来强调表或图表中的数据。 类似地,格式化对象可以用于增加表或图表中的信息密度,并且优雅地表示二维图中四个或更多个相关变量之间的关系。 格式化对象通过定义至少一个包含一个或多个映射段的格式映射来实现。 每个映射段包括开始边界值,结束边界值,对应于开始边界值的至少一个开始视觉属性,以及对应于结束边界值的至少一个结束视觉属性。 格式化对象使用格式图中的信息结合插值技术来确定对应于落在各种映射段内的数据点的一个或多个视觉属性。 然后,格式化对象通过将适当的视觉属性应用于显示在计算机屏幕上的可视对象来表达数据值。
