    • An air flow regulator includes a damper (14) and an air cylinder (20) operatively connected with the damper (14) to adjust a damper setting. A pressure sensor (52) indicates a pneumatic pressure in the air cylinder (20). An air pressure regulator (42) is operatively connected with the air cylinder (20) to pressurize and exhaust the air cylinder (20) responsive to an electrical input (70). The air pressure regulator (42) includes a calibration table (64) associating steady state air cylinder pressure values with regulator shut-off pressure values. Responsive to the electrical input (70) updating a steady-state air cylinder pressure value, the air pressure regulator (42) pressurizes or exhausts the air cylinder (20) until the pressure sensor (52) indicates a pressure corresponding to a regulator shut-off pressure value associated in the calibration table (64) with the updated steady-state air cylinder pressure value, whereupon the air pressure regulator (42) ceases the pressurizing or exhausting.
    • 气流调节器包括阻尼器(14)和与阻尼器(14)可操作地连接以调节阻尼器设定的气缸(20)。 压力传感器(52)表示气缸(20)中的气动压力。 空气压力调节器(42)与气缸(20)可操作地连接,以响应于电输入(70)对气缸(20)进行加压和排气。 空气压力调节器(42)包括将稳态气缸压力值与调节器关闭压力值相关联的校准表(64)。 响应于更新稳态气缸压力值的电输入(70),空气压力调节器(42)对气缸(20)进行加压或排气,直到压力传感器(52)表示对应于调节器关闭的压力, 在校准表(64)中与更新的稳态气缸压力值相关联的关闭压力值,于是空气压力调节器(42)停止加压或排气。

    • The electronic device uses domino-shaped sound elements in combination with a support track to generate audible sounds or musical notes. The sound elements are placed in indentations on a support track in a selected sequence corresponding to the sequence of musical notes in a song to be played. Each of the sound elements corresponds to a single sound or musical note. When the sound elements are toppled in a domino-type manner, the notes are played in the selected sequence. Each of the sound elements has one or more magnetic elements in its bottom surface. The movement of the magnetic element away from associated Hall Effect sensors in the support track during toppling of the sound elements is used to trigger a decoding circuit. The decoding circuit determines the note pattern and generates the associated sound through an output speaker. A timbre sound element may also be used to select the timbre or other tonal characteristics of the output sounds.
    • 电子设备使用多米诺骨牌声音元素与支撑轨道组合以产生可听见的声音或音符。 声音元素以对应于要播放的歌曲中的音符序列的选定顺序放置在支撑轨道上的凹陷中。 每个声音元素对应于单个声音或音符。 当声音元素以多米诺骨牌型推出时,音符按所选顺序播放。 每个声音元件在其底表面中具有一个或多个磁性元件。 在声音元件翻转期间,磁性元件远离相关的霍尔效应传感器在支撑轨道中的运动被用于触发解码电路。 解码电路通过输出扬声器确定音符模式并产生相关联的声音。 还可以使用音色声音元素来选择输出声音的音色或其他音调特征。
