  • Publication number: 20150209204
    Abstract: An intelligent walker includes a holder, a support frame, a sensing grip, a driving device, and a control device. The support frame is configured for supporting the holder. The bottom side of the support frame is disposed with a plurality of wheels. The driving device is configured for driving the wheels so as to move the intelligent walker. The sensing grip is disposed behind the holder and has a pressure-sensing element. The pressure-sensing element is configured for sensing the magnitude of a force of a user's hands and a position of the user's hands on the sensing grip and for generating a sensing signal. The control device is connected to the pressure-sensing element and the driving device, and configured for receiving the sensing signal and generating a control signal. The driving device receives the control signal and correspondingly changes the movement speed and direction of the intelligent walker.

  • Patent number: 8943908
    Abstract: The present invention is to provide an imperceptible motion sensing device, which includes a non-conductive elastomer made of a pliable and elastic non-conductor (e.g., polyurethane) and having a bumpy side formed with at least one sunken portion thereon, at least one conductive fiber positioned in the at least one sunken portion respectively (e.g., by sewing), and a conductive elastomer made of a pliable and elastic conductor (e.g., a conductive foam or conductive rubber) and provided on the bumpy side of the non-conductive elastomer. When the sensing device is compressed by an external force, corresponding portions of the conductive elastomer and the non-conductive elastomer are compressed and deformed, causing contact and hence electrical connection between the conductive elastomer and the at least one conductive fiber. Thus, the imperceptible motion sensing device not only provides more accurate and more sensitive signal detection, but also ensures consistent performance even after long-term use.
