摘要:
Disclosed embodiments relate to methods, apparatuses, and systems for characterizing gait. Specifically, disclosed embodiments are related methods, apparatuses, and systems for characterizing gait with wearable and wirelessly synchronized inertial measurement units. These include a method for gait characterization that comprises (a) detecting zero-velocity periods using two or more wearable and wirelessly synchronized movement monitoring devices including a triaxial accelerometer and a triaxial gyroscope and (b) calculating temporal measures of gait during walking by estimating the change in position and orientation during each step.

Disclosed embodiments include a movement monitoring system and apparatus for objective assessment of movement disorders of a subject, comprising (a) one or more movement monitors, and (b) a computer-implemented analysis system comprising one or more protocols and associated data analysis methods to objectively quantify movement disorders based on movement data acquired by the movement monitors. According to one embodiment, the movement monitors are robust wireless synchronized movement monitors and the protocols include one or more tests for assessment of neural control of balance.
摘要:
The invention relates to a condenser type barrier for field control in transformer bushings and their connection to the conductor of a transformer winding for transformers used in HVDC converter plants. The condenser barrier is arranged as a solid of revolution with concentrically laid condenser layers. It is formed from both ends with inwardly-directed, straight frustums of cones with equally large smallest bases, between which the condenser barrier is formed as a concentric inner, straight circular cylinder.
