摘要： A motion-based push activation power assist system for manual wheelchairs. The system uses motion-based measurements to determine when the user applies a push to the wheelchair handrims and brakes with the handrims. The push recognition activates a drive system that provides an assistive driving force-pulse to the wheelchair to reduce the demand on the user during propulsion. The brake recognition deactivates the power assist. The provided power assist is proportional to the sensed push and can be modulated to different proportional settings.
摘要翻译：一种用于手动轮椅的基于运动的推动启动动力辅助系统。该系统使用基于运动的测量来确定用户何时将手推到轮椅手臂上并用手柄制动。推动识别激活驱动系统，其向轮椅提供辅助驱动力脉冲以减少在推进期间对用户的需求。制动识别使电源辅助失效。所提供的功率辅助与感测到的推压成比例，并且可以被调制成不同的比例设置。

摘要： An adjustable manual wheelchair handrim with a moveable elastomeric friction band. The position of the tubular handrim can be moved to a desired location relative to the wheel rim depending on the needs and limits of the user. The movable friction band is stretched around the drive surface of the handrim at a desired location preventing it from moving and providing increased frictional properties when gripped by the user during pushes. The friction band can be permanently affixed at a location to further prevent movement and slippage between the handrim and the friction band.
摘要翻译：一个可调节的手动轮椅扶手带有可移动的弹性摩擦带。根据用户的需要和限制，管状手指的位置可相对于轮辋移动到期望的位置。可移动的摩擦带在所希望的位置处被拉伸在手指的驱动表面周围，从而防止它在移动时被使用者在推动时握住时提供增加的摩擦特性。摩擦带可以永久地固定在一个位置，以进一步防止手指和摩擦带之间的运动和滑动。
