  • Patent number: 10790297
    Abstract: Embodiments of methods for forming channel holes in 3D memory devices using a nonconformal sacrificial layer are disclosed. In an example, a dielectric stack including interleaved first dielectric layers and second dielectric layers is formed on a substrate. An opening extending vertically through the dielectric stack is formed. A nonconformal sacrificial layer is formed along a sidewall of the opening, such that a variation of a diameter of the opening decreases. The nonconformal sacrificial layer and part of the dielectric stack abutting the nonconformal sacrificial layer are removed. A channel structure is formed in the opening after removing the nonconformal sacrificial layer and part of the dielectric stack.

  • Publication number: 20200289047
    Abstract: The invention provides a fetal movement monitoring system which uses optical pattern sensing to detect fetal movements. Fetal movements provide a change in the optical path between the optical sensor and detector, such as a different proportion of amniotic fluid and fetus and/or a different contact pressure with the optical sensor arrangements. One or both of these effects may be detected based on analysis of the optical signals captured by the system.

  • Publication number: 20200258757
    Abstract: In the disclosed method, a mask is formed on a microstructure. The mask includes a first pattern positioned over a first region of the microstructure and a second pattern positioned over a second region of the microstructure. A first etching process is performed to etch the microstructure according to the first and second patterns formed in the mask. The first etching process transfers the first and second patterns of the mask into the first and second regions of the microstructure, respectively. A protective layer is subsequently formed over the first pattern of the mask that is positioned over the first region of the microstructure. When the protective layer is formed, a second etching process is performed to etch the microstructure and transfer the second pattern of the mask further into the second region of the microstructure. The method also includes removing the mask and the protective layer from the microstructure.

  • Patent number: 10722745
    Abstract: Systems and methods for a muscle signal-driven cycling system for persons with disability for rehabilitation are provided. A system comprises integrating both motor power and muscle power to facilitate rehabilitation cycling-based exercises. By using the intensity of real-time muscle activity signals as inputs, a motor applies either assistive or resistive force to rotate a gear at different speeds to facilitate or impede the cycling motion, and the electrical pulses from an electrical stimulation device can be provided to stimulate target muscles to generate muscle contraction to support the continuous cycling movement.

  • Publication number: 20190322098
    Abstract: An apparatus and method of manufacturing a fluorosilicone composite for a variable data lithography imaging member surface layer. Examples of the fluorosilicone composite include a first part and a second part, the first part having fluorosilicone, carbon black, silica and butyl acetate, the second part having a platinum catalyst, a crosslinker, butyl acetate and an inhibitor. The first part may also include a dispersant (e.g., a polyoxyalkylene amine derivative) that removes a need for shaking the dispersion by paint shaker and instead allows a more manufacture friendly roll ball milling process. The dispersant will also help in stabilizing the fluorosilicone composite for scaled up production.
