摘要： A fluid-ejection device includes a handheld and/or mountable enclosure, a removable tip, a cap, a pneumatic fitting, and a controller. The removable tip has a fluid-ejection mechanism located at an end thereof. The cap is disposed on the end of the removable tip such that just the fluid-ejection mechanism is exposed through the cap. The pneumatic fitting extends from the enclosure and is receptive to placement of the removable tip thereon. The controller is situated within the enclosure to cause the removable tip to eject fluid.

摘要： A safety workbench includes a work chamber enclosed by a housing, including a work opening located in the housing front side and settable using an adjustable front pane to let in an external air flow flowing into the work chamber, and including at least one fan for delivering the external air flow into the safety workbench. To improve the working conditions of the safety workbench for operators while simultaneously ensuring sufficient personal protection at all times, a regulating unit and/or a control unit is provided, by which the delivery output of the at least one fan can be regulated and/or controlled as a function of the front pane position.
摘要翻译：安全工作台包括由壳体包围的工作室，其包括位于壳体前侧中的工作开口，并且可使用可调节的前窗玻璃设置，以使外部气流流入工作室，并且包括至少一个用于传送的风扇外部空气流入安全工作台。为了改善操作员的安全工作台的工作条件，同时确保足够的人身保护，提供调节单元和/或控制单元，通过该调节单元和/或控制单元可以调节至少一个风扇的输出输出和/或作为前窗格位置的函数进行控制。

摘要： A fume hood comprised of: a first and second side wall, a back wall, a work surface, and a top wall, which define a work area; an access opening for providing a user access to the work area; a movable sash member disposed within the fume hood for movement across the access opening to vary the effective size thereof; a drive motor mechanically coupled to the movable sash member; and a pressure-sensitive switch disposed on the bottom surface of the movable sash member. Upon a pressure being exerted on the pressure-sensitive switch in excess of a threshold limit, either by a user pressing against it or by the movable sash member encountering an object left within the access opening, movement of the movable sash member is ceased. The fume hood unit is coupled to an operator sensor to close the sash when the fume hood is not in use.
摘要翻译：一种通风橱，包括：第一和第二侧壁，后壁，工作表面和顶壁，其限定工作区域; 用于提供用户对工作区域的访问的访问开口; 布置在所述通风橱内的活动窗扇构件，用于穿过所述进入开口移动以改变其有效尺寸; 驱动马达，机械地联接到可动窗扇构件; 以及设置在可动窗扇构件的底面上的压敏开关。当压力超过阈值极限时，通过使用者按压压力敏感开关或者通过可动窗扇构件遇到留在进入开口内的物体，停止活动窗扇构件的运动。当通风橱不使用时，通风橱单元联接到操作者传感器以关闭窗扇。

摘要： A fume hood optical sash sensing system for controlling the flow of air into a fume hood to maintain a constant face velocity by utilizing an optical sensing device mounted inside the fume hood that can sense the movement of a sash based on repeatable reflexive tape to produce an output control signal that corresponds to sash movement to produce desired airflow into the fume hood. The system includes an optical sensing device with a light source, reflexive tape with a repetitive, quadrature encoded pattern, a smart controller device that receives output control signals from the optical sensing device, and an actuation device capable of receiving the output signal from the controlling device to control the damper device that will result in constant face velocity across the face of the sash.
