摘要： An adjustable ergonomic back for a seat is disclosed. The back has a plurality of back cushions, each cushion having at least one adjustment area. It further comprises a structural shell having a plurality of voids therein. A plurality of thin flexible elements are located between the back cushions and the structural shell, each flexible element being attached to the structural shell. Each of the flexible elements has a front surface and a back surface, the front surface being in contact with a respective adjustment area of one of the plurality of back cushions. The back further has a plurality of actuators located between the flexible elements and the structural shell, each of the actuators being in contact with one of the respective back surfaces of the flexible elements and exerting a pressure on the back surface.

摘要： An adjustable grade stick and method of using the same are used to identify a reference line. The grade stick has a shaft that is adjustable along its length. In a preferred embodiment, the shaft has two sections where one section lies within the other in a variably telescoping manner. A locking device is provided to lock the relative positions of the first and second sections of the shaft. A hook is located at one end of the shaft to mount the shaft on the ceiling of the mine tunnel. A sighting ring is located at the other end of the shaft and has an inner aperture which acts as a marker for a reference point. A calibration scale is located on the shaft for positioning the sighting means at a predetermined location. The reference line is sighted from the sighting rings of a pair of grade sticks. A method of using the grade sticks consists of taking a pair of the adjustable grade sticks, adjusting their lengths to predetermined settings, mounting the grade sticks on the ceiling of a mine tunnel at predetermined locations and aligning the sighting rings on each shaft to form a reference line which is used to guide drilling operations within the mine.
摘要翻译：使用可调节级棒及其使用方法来标识参考线。等级棒具有沿其长度可调节的轴。在优选实施例中，轴具有两个部分，其中一个部分以可变地伸缩的方式位于另一部分内。提供锁定装置以锁定轴的第一和第二部分的相对位置。钩位于轴的一端，以将轴安装在矿井隧道的天花板上。瞄准环位于轴的另一端，并且具有作为参考点的标记的内孔。校准刻度尺位于轴上，用于将瞄准装置定位在预定位置。参考线从一对等级棒的瞄准镜看到。使用等级棒的方法包括一对可调节级棒，将其长度调节到预定的设置，将等级棒安装在预定位置的矿井隧道的天花板上，并将每个轴上的瞄准环对准以形成参考线，用于指导矿井内的钻井作业。
