    • A torque transmitting device (10) includes a clutch housing (14) rotatable about an axis (A), a first set of clutch plates (20A) splined to the clutch housing (14), and a second set of clutch plates (20B) interleaved with the first set and rotatable about the axis (A) of rotation. A push plate assembly (28) is splined to the clutch housing (14) for rotation therewith. A roller assembly (42) includes a roller housing (48) splined to the clutch housing (14), a roller supporter (54) housed in the roller housing (48), and a roller element (62) supported by the roller supporter (54). A wedge assembly (12) includes a wedge housing (64) connected to a wedge block (24). The wedge housing (64) includes a ramp member (70) defining a ramp surface (16) with the roller element (62) contacting the ramp surface (16). A motion converter (71) is disposed between the push plate assembly (28) and the wedge housing (64) such that axial movement of the push plate assembly (28) causes rotation of the wedge assembly (12) relative to the roller assembly (42).

    • A method to achieve rapid 3D printing of microneedle patches. The 3D printing method comprises a printing nozzle of multiple micro-holes and cold plate/platform on which the microneedle-supporting sheet (membrane) is placed. The solution or aqueous solution of microneedle-forming materials is printed onto the cold microneedle-supporting sheet with programed rate of injection from the nozzle and velocity of the nozzle lifting. The relationship between the injection rate and the lifting velocity determines the shape of the microneedle tips. The freshly printed microneedles on the cold sheet are dried in two ways, drying at a temperature close to the ice point of water or drying after a freeze-thaw treatment of the microneedles.
    • 实现微针贴片快速3D打印的方法。 3D打印方法包括多个微孔的打印喷嘴和其上放置微针支撑片(膜)的冷板/平台。 微针形成材料的溶液或水溶液被印刷到冷的微针支撑片上,其具有从喷嘴喷射的程度和喷嘴提升的速度。 注射速度与提升速度之间的关系决定了微针尖的形状。 在冷片上新鲜印刷的微针以两种方式干燥,在接近冰点的温度下干燥或在微针的冻融处理后干燥。
