摘要： A toner mass developed control system for use with electronic printers or copiers provides for the measurement of toned photoconductor reflectivity and bare photoconductor reflectivity. The standard control ratio is modified by characterizing the particular sensor unit in use and by taking into account the reflectance from both photoconductor and toner in the toned patch reflectivity measurement. These factors together with a modification for photoconductor reflectance degradation enable accurate control in high optical density development and with highly reflective color toners by altering the control ratio in accordance with these factors.

摘要： A system for damping and/or stiffening a ski having a damping member and a stiffening member which are engageable and disengageable through the operation of a switch member. The switch member is engaged by a change in a threshold condition, such as a shift in the skier's weight during skiing. Engagement of the switch member engages the damping member and/or stiffening member. The system maintains the damping member and/or stiffening member in a disengaged condition until the skier commences a turn, engages the damping member and/or the stiffening member during the turn, and disengages the damping member and/or the stiffening member once the turn is completed.
摘要翻译： 一种用于阻尼和/或加强滑雪板的系统，所述滑雪板具有通过开关构件的操作可接合和分离的阻尼构件和加强构件。 开关构件通过阈值条件的改变而啮合，例如滑雪者在滑雪者的重量上的变化。 开关构件的接合与阻尼构件和/或加强构件接合。 系统将阻尼构件和/或加强构件保持在分离状态，直到滑雪者开始转弯，在转弯期间与阻尼构件和/或加强构件接合，并且一旦转动就解除了阻尼构件和/或加强构件 完成了。
