  • Patent number: 9604697
    Abstract: A mobility vehicle includes a personal mobility vehicle having at least one wheel body and a power-assisting system. The power-assisting system includes an actuation unit, a sensing unit and a signal processing unit. The actuation unit has a motor and a power amplifier geared with the motor. The sensing unit includes a motor rotation speed sensor, a multi-axis accelerometer and a multi-axis gyroscope, so as to sense the velocity, acceleration and the absolute angular velocity of the mobility vehicle in motion in real time. The signal processing unit is connected to the actuation unit and the sensing unit, so as to process the signals of the sensing unit. Then, the actuation unit performs inertia compensation, damping compensation and gravity compensation to the mobility vehicle through a dynamic signal-conditioning algorithm. When the mobility vehicle is actuated by human-power, the power-assisting system assists the power automatically to save human labor.

  • Patent number: 9079633
    Abstract: Uni-wheel personal mobility vehicle with self-balancing function is disclosed. This transportation device can be pedaled by a driving force provided by the driver's manpower and/or the in-wheel motor's electric power. The uni-wheel personal mobility vehicle with self-balancing function is equipped with an inertial sensing and control driving module, an in-wheel motor, and a steering mechanism consisting of a transmission pulley set, an idle pulley set, a transmission cable, and a spring set, therefore the personal mobility vehicle can simultaneously maintain its self balance when being propelled by driver's pedaling force or the in-wheel motor's electrical torque; moreover, the driver can also make the personal mobility electric vehicle change its direction by rotating a handlebar similar to steering a bicycle, wherein the rotation of the handlebar would simultaneously pull one side of the transmission cable via the transmission pulley set to steer the vehicle and maintain its lateral balance.

  • Patent number: 7276828
    Abstract: A magnetic bearing system for a rotating machine is disclosed. The magnetic bearing system provides a non-contacting radial rigid support for the rotating machine by employing two magnetic assemblies each being formed by stacked annular magnets. The magnetic assemblies are mounted separately on a shaft of the rotating machine and a shaft hole provided on the stator seat of the rotating machine for containing the shaft.
