摘要： An approach for restoring friction level of a surface is disclosed. The approach comprises of utilizing IoT devices, digital twin simulation and 3D printing to actively monitor and adjust surface friction of surfaces, rather than simply applying a passive anti-slip coating. Furthermore, the approach can take into account various factors such as surface inclination, payload movement, and mobility path (via one or more simulations in a digital twin environment) in order to determine the necessary level of surface friction and the appropriate means of restoring it. The approach also allows for the determination of the required surface roughness and the selection of appropriate materials and printing methods in order to achieve it.

摘要： The present disclosure is directed to ion-exchange systems and devices that include composite ion-exchange membranes having 3D printed spacers on them. These 3D printed spacers can drastically reduce the total intermembrane spacing within the system/device while maintaining a reliable sealing surface around the exterior border of the membrane. By adding the spacers directly to the membrane using additive manufacturing, the amount of material used can be reduced without adversely impacting the manufacturability of the composite membrane as well as allow for complex spacer geometries that can reduce the restrictions to flow resulting in less pressure drop associated with the flow in the active area of the membranes.

摘要： Support structures are used in certain additive fabrication processes to permit fabrication of a greater range of object geometries. For additive fabrication processes with materials that are subsequently sintered into a final part, an interface layer is formed between the object and support in order to inhibit bonding between adjacent surfaces of the support structure and the object during sintering.

摘要： A wind turbine blade includes a lengthwise portion that extends between a root region and a tip region of the wind turbine blade. The lengthwise portion includes a cross section in which a first region surrounds a second region. The densities of the first and second regions vary with the first density being greater than the second density. The lengthwise portion includes a surface layer that bounds the first region, forms an exterior surface, and is configured to resist environmental degradation. At least one structural element extends longitudinally through the first region and is configured to reinforce the blade during use of the wind turbine. The lengthwise portion of a wind turbine blade may be made through an additive manufacturing process by depositing a main body in a plurality of layers. Each layer may be deposited in a plane generally parallel to a longitudinal axis of the lengthwise portion.

摘要： A smart ring includes a body including flexible material, a first part, a second part removably connected to the first part, and at least one pair of break-away portions disposed within the body separate from the first part and the second part. One or more of a battery, a charging unit, a processor unit, a user input unit, a communication unit, a memory unit, at least one sensor unit, an output unit or a user input unit is disposed in or on one of the first part and the second part. Each of the break-away portions of the pair of break-away portions is removable from the other break-away portion upon movement of one break-away portion in a direction away from the other break-away portion.
