  • Patent number: 11048776
    Abstract: A method is provided for the automatic control of cycling speed in a human. The method comprises: estimating the subject's actual cycling speed using one or more sensors to thereby obtain a measured speed; determining an error comprising a difference between a desired speed and the measured speed; and outputting, to the subject, a stimulus frequency signal wherein the stimulus frequency signal is based on the error in such a manner that when the subject pedals in a manner that matches a frequency of the stimulus frequency signal, the subject's actual speed controllably tracks the desired speed.

  • Patent number: 11015672
    Abstract: A bicycle with a suspension system for a wheel of the bicycle, the suspension system including a smart fluid damper for dampening a movement of the wheel relative to the frame. The smart fluid damper includes a flow control element disposed within a cavity of the damper and configured to apply a field to a smart fluid within a fluid passage extending through the flow control element. The flow control element includes field barriers proximate the fluid passage to locally block and/or divert the field such that the field cannot pass therethrough. The field barriers are arranged to cause the field to criss-cross the fluid passage at multiple axial intervals along the fluid passage, thereby focusing the field within the fluid passage.

  • Publication number: 20210137184
    Abstract: Generally described, aspects of the disclosed subject matter are directed to impact mitigating membranes. In accordance with aspects of the present disclosure, the impact mitigating membranes generally include a laminar core having a first lamina and a second lamina coupled to the first lamina and configured to shift relative to the first lamina to dissipate kinetic energy resulting from an oblique impact force. The laminar core may include a lubricating layer or self-lubrication between the lamina to reduce friction. In general, the laminar core is surrounded by first and second encapsulating layers positioned adjacent each lamina. An anchoring attachment coupled to one or more of the first and second encapsulating layer and associating with the laminar core constrains relative lateral motion between the laminar core and the first and second encapsulating layers.

  • Patent number: 10895604
    Abstract: Systems and methods to provide a low voltage interface coupleable between an energy storage device or a DC power source (e.g., fuel cell stack, battery) and one or more AC signal diagnostic systems. The low voltage interface reduces a voltage of the DC power source and supplies the reduced voltage to the one or more AC signal diagnostic systems without affecting the results of the measurements obtained by the one or more AC signal diagnostic systems. Such functionality provides a safer method for performing advanced analysis (e.g., EIS, frequency analysis) while utilizing lower cost and/or smaller components.

  • Publication number: 20200011666
    Abstract: The disclosed devices utilize nonlinearly coupled modes of vibration to provide robust inertial sensors, such as gyroscopes. This actuation mechanism introduces a wider bandwidth in the sense-mode frequency response curve, and consequently enhances robustness to parameter fluctuations due to operating conditions and fabrication imperfections. The vibratory modes of the device are designed to have distinct frequencies where the drive-mode natural frequency is twice the modal frequency of the sense mode. The nonlinear modal interaction due to internal resonance can also be magnified through nonlinearity feedback. The sense mode response can be enhanced in shape, quality factor, and bandwidth by feeding back nonlinear quadratic, cubic, etc. terms.
