Abstract: A method removing artifacts from neural signals comprises receiving electroencephalography (EEG) data from an EEG system and providing the EEG data to a unified artifact removal framework for cleaning artifacts. The EEG data is provided to a first cleaning framework utilizing the first reference to clean first artifacts from the EEG data, and the outputting the EEG data from the first cleaning framework to a second cleaning framework. The second cleaning framework may operate in a similar manner utilizing second reference to clean second artifacts from the EEG data. This general process may be repeated as desired to clean various artifacts from EEG data, when a suitable reference for the artifacts to be removed is utilized. The frameworks utilize H∞ method or filtering involving a H∞ adapting rule to properly weigh the reference, and combining the subsequent output with incoming EEG data results in the desired removal of artifacts.

Abstract: Improved customizable orthotic/prosthetic braces and a lightweight modular exoskeleton may aid individuals with lower limb motor impairment, including children. These customizable orthotic/prosthetic braces improve the strength and rigidity of such braces without a weight penalty. A structural frame is embedded between an inner shell and outer shell, which comprise materials that are easily moldable to conform to a user's limb. The lightweight modular exoskeleton system provides six (6) joint actuators, which are designed to be modular, that act as the active joints (e.g. hips, knees, and ankles) of the exoskeleton. Additionally, the exoskeleton may also provide four (4) passive joints for inversion/eversion of the legs and feet. Foot, crutch, and hip assemblies may also be provided for the exoskeleton. Further, the six joint actuators may be utilized between the hip brace assembly and thigh brace assembly, the thigh and shank brace assembly, and the shank brace assembly and foot assembly, where the braces may correspond to the customizable orthotic/prosthetic design. The modularity of the actuators and braces allows for exoskeleton assemblies that can be tailored to patient specific needs.

Abstract translation: 改进的可定制矫形/假肢矫形器和轻量化模块化外骨骼可以帮助患有下肢运动障碍的患者，包括儿童。 这些可定制的矫形/假肢矫正器可以在不增加体重的情况下提高这种矫正器的强度和刚度。 结构框架嵌入在内壳和外壳之间，其包括易于模制以符合使用者的肢体的材料。 轻型模块化外骨骼系统提供六（6）个关节致动器，这些致动器被设计成模块化的，用作外骨骼的活动关节（例如臀部，膝盖和脚踝）。 另外，外骨骼还可以提供四（4）个被动关节，用于腿部和脚部的倒置/外翻。 可以为外骨骼提供脚，拐杖和髋关节组件。 此外，六个关节致动器可以用于髋支架组件和大腿支具组件，大腿和胫骨支具组件，以及胫骨支具组件和蹄组件，其中支具可以对应于可定制的矫形/假体设计。 执行器和支架的模块化使得外骨骼组件可以根据患者的具体需求量身定制。
