    • A guide system is provided that uses a plurality of sensors to identify and determine a clear path for an ambulatory vision impaired person. The system includes one or more wheels that rotate to propel the system, a platform supported by the one or more wheels and housing a processor, a rigid harness with a haptic feedback grip that is positioned to be grasped by an operator, and one or more sensors configured to sense information about the environment. In operation, the processor analyzes information sensed by the sensors to identify object in the path of the guide system and sends messages to the operator to allow the operator to avoid the identified objects. The messages may be sent to the operator via the haptic feedback grip or audibly via a speaker or via a wireless connection to a haptic or audio device being worn by the operator.
    • 提供了一种引导系统,其使用多个传感器来识别和确定行动不便的视障人士的畅通路径。 该系统包括旋转以推进系统的一个或多个轮子,由一个或多个轮子支撑并容纳处理器的平台,具有定位成由操作员抓住的触觉反馈握把的刚性束带以及一个或多个 配置成感测关于环境的信息的传感器。 在操作中,处理器分析由传感器感测到的信息以识别引导系统的路径中的对象,并向操作员发送消息以允许操作员避开所识别的对象。 这些消息可以通过触觉反馈手柄或可听地通过扬声器或通过无线连接被发送给操作员到操作员佩戴的触觉或音频设备。

    • A manual wheelchair including a collapsible frame having a first lateral member that is connected to first and second braces at their respective first ends. A drive wheel axel extends along a first axis of rotation and engages a drive wheel, the first brace, and a portion of a transmission. A push rim axel extends along a second axis of rotation and engages a push rim wheel, the second brace, and a portion of the transmission, which transmits rotation of the push rim to rotation of the drive wheel. The collapsible frame additionally includes a second lateral member that is connected to the first and second braces as their respective second ends. The first and second braces are configured to release the second lateral member to collapse the manual wheelchair.
