Abstract: A machine posture inspection method and a machine posture inspection system are provided. The method includes: configuring an image capturing device to capture a current image of a region where a machine device is located, and configuring a processing device to: identify a reference marker in the current image and a first marker connected to the machine device; and calculate and obtain a current posture of the machine device according to the reference marker and the first marker; configure a motor encoder to measure an encoder signal associated with a motor; and determining whether or not the machine device is abnormal according to the current posture and the encoder signal.

Abstract: In this invention, a novel wearable device is proposed for long-time measurement of user's spine posture and alignment. Mechanically, the device primarily comprises an actuation module, a measurement mechanism, and a processing module positioned on the wearing component. The measurement mechanism includes a primary measurement unit and at least one secondary measurement unit. These measurement units are interconnected in series, forming an underactuated mechanism, and are actuated by the actuation module. On each first primary/secondary rotational axis, at least one angular sensor is employed to measure the angle change relative to the adjacent measurement unit. The processing module is electrically connected to both the actuating module and at least one angular sensor, allowing it to receive angle change signals from the sensors and transmit a measurement signal from the wearable spinal measurement device.

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.

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.
