  • Publication number: 20220392370
    Abstract: The present invention relates to a virtual reality-based task-oriented gait training system and method, in which the virtual reality-based task-oriented gait training system according to the present invention includes a gait detection unit that detects a walking movement of a trainee, a projector unit that projects virtual walking environment information for inducing a gait training of the trainee, and a control unit that executes a walking training program to change the virtual walking environment information according to the detected walking movement of the trainee, in which the virtual walking environment information includes a background constructing a virtual space and a walking training object appearing in the virtual space, and the gait training object includes a virtual obstacle for disturbing the walking movement of the trainee according to a preset level of difficulty or a gait inducing object for inducing gait of the trainee with a predetermined stride length.

  • Patent number: 9559187
    Abstract: A semiconductor device includes a plurality of epitaxial layers stacked over a supportive substrate, a first buried impurity region formed to share the supportive substrate with a lowermost epitaxial layer among the multiple epitaxial layers, one or more second buried impurity regions formed to be coupled with the first buried impurity region and share an Nth epitaxial layer and an (N+1)th epitaxial layer among the multiple epitaxial layers, where N is a natural number, a body region formed in an uppermost epitaxial layer among the multiple epitaxial layers and a deep well formed in the uppermost epitaxial layer to surround the body region and to be coupled with the second buried impurity regions that share the uppermost epitaxial layer.
