    • An acoustic attenuator includes a housing having an inner side surface which defines an interior chamber and at least one dampening member both physically and acoustically coupled to the housing and projecting into the interior chamber. Acoustic energy propagating within the housing is deflected into the dampening members for acoustically dispersal within the interior chamber. In various aspects thereof, the dampening members may include one or a group of two or more generally cylindrical sleeves having one end both physically and acoustically coupled to the housing and a second end projecting into the interior chamber. Preferably, when a group of two or more cylindrical sleeves are employed, the sleeves are nested within one another. The dampening members may further include a second, oppositely disposed, group of two or more acoustic attenuators nested within one another and interdigitated with the first group of cylindrical sleeves.
    • 声衰减器包括壳体,该壳体具有限定内腔的内侧表面和至少一个阻尼构件,物理和声学耦合到壳体并突出到内腔中。 在壳体内传播的声能被偏转到阻尼构件中,用于在内腔内声扩散。 在其各个方面,阻尼构件可以包括一个或一组两个或更多个大致圆柱形的套筒,其中一个端部物理上和声学上耦合到壳体,第二端突出到内部腔室中。 优选地,当使用一组两个或更多个圆柱形套筒时,套筒彼此嵌套。 阻尼构件还可以包括彼此嵌套的两个或更多个声衰减器的第二相对设置的组,并与第一组圆柱形套筒相互指向。

    • A system for raising and lowering a sectional overhead door between an open position and a closed position including, a counterbalance system adapted to be connected to the door, an operator motor assembly mounted proximate to the sectional overhead door in the closed position of the sectional overhead door, at least a portion of the operator motor assembly movable between a door operating position and a door locking position, and a locking assembly (370) having an engaged position to hold the motor assembly in the operating position and a disengaged position to release the motor assembly allowing it to move to the door locking position. The system may be provided with a remote light assembly having a switchable light source in sensing communication with the operator motor such that operation of the motor activates the light source. The system is further provided with a handle assembly (515) operatively engaging the motor assembly (40) and counterbalance system (30) to selectively disconnect the motor assembly (40) from the counterbalance system (30), whereby urging of a rotatable handle (516) to a disconnect position (516′) allows the door (D) to be manually freely moveable with the aid of the counterbalance system (30).
