    Abstract: A sash position sensing system for a fume hood (10) and the like having a plurality of movable sashes (12a, 12b, 12c, 12d) in a frame includes an indicator element (24) affixed to each sash and an array (20) of sensor elements (22) extending along the frame. The sensor elements interact with the indicator elements when generally aligned therewith. The status of the sensor elements is captured in parallel without the need for multiplexing the sensor array, and a processor (52) reads the captured state information and calculates the open area of the frame. In further aspects, a method for determining the position of one or movable sashes in a frame and a fume hood employing the sash position sensing system of the present invention are also provided.

    Abstract translation: 在框架中具有多个可移动窗扇(12a,12b,12c,12d)的通风橱(10)等的窗框位置检测系统包括:固定到每个窗框的指示元件(24)和阵列(20), 的传感器元件(22)沿框架延伸。 当与其大致对准时,传感器元件与指示元件相互作用。 传感器元件的状态并行捕获,而不需要复用传感器阵列,并且处理器(52)读取捕获的状态信息并计算帧的开放区域。 在另外的方面,还提供了一种用于确定框架中的一个或可动窗扇的位置的方法以及采用本发明的窗框位置感测系统的通风橱。
