Abstract: A system and method for detecting failure of a steering angle sensor include: a steering angle sensor, an angular position encoder and an electronic control unit. The electronic control unit reads an initial value of the steering wheel rotation angle signal and estimates a rotation angle of a steering wheel based on the motor rotation angle signal, the electronic control unit checks if a difference between an actual value of the steering wheel rotation angle signal and an estimated rotation angle of the steering wheel is smaller than a predetermined value or not, if the difference is bigger than the predetermined value, it means that the steering wheel rotation angle signal fails, and the estimated rotation angle of the steering wheel serves as a substitute signal and is sent to the electronic control unit.

Abstract: A robotic arm includes first and second bent links and a tool link pivotally connected in order, first to third wheels, and first to fourth imaginary axes intersecting at a center of spherical rotation. The first bent link and wheel are driven to rotate about the first and third imaginary axes respectively. A first flexible rope is wound around the first and second wheels and fixed to the second bent link for driving the second wheel and bent link to rotate about the second imaginary axis when the first wheel rotates. A second flexible rope is wound around the second and third wheels and fixed to the first bent link for driving the third wheel and the tool link to rotate about the fourth imaginary axis when the second wheel rotates. The robotic arm is relatively smaller, obstructs the operator less and produces a wider sphere of action.

Abstract: A ball screw with support devices includes a nut base having two sides equipped with the support devices for preventing the screw from deflection. Two runner structures are provided near two ends of the screw. The runner structure includes a driving wheel and a driven wheel having different diameters and concentrically installed. The nut base is connected to the driving wheel via an active connecting element for driving the driving wheel to rotate. The driven wheel moves with the driving wheel and is connected to the support devices via passive connecting elements so that the support devices and the nut displace synchronously. By controlling a diameter ratio between the driving and driven wheels, the nut and the support devices displace with proportional speeds, thereby allowing the support devices to always stay at the two sides of the nut as designed and provide reliable support.

Abstract: A linear actuator includes a slide, a first half return member, a second half return member and a slide block. The first and second half return members are hollow frames and sleeved onto the rail. A circulation path can be formed when the first and second half return members and the slide block are assembled together, the second half return member is directly disposed in the first radial gap of the first half return member, and the slide block is directly disposed in the second radial gap of the second half return member. Furthermore, there is no level difference in the first and second return grooves of the two half return members, which will prevent noise caused during movement of the rolling elements, reduce impact of the rolling elements against the circulation path, and therefore extending the life of the linear actuator.

Abstract: A method for controlling gait-training apparatus using biofeedback is provided. A biosignal-detecting loop is used to detect and analyze the electromyographic signal of a user using the gait-training apparatus. A feedback control loop is used to drive the gait-training apparatus and determine the fatigue level of the user. When the user's muscle starts to become fatigue, the feedback control loop can further adjust the threshold for triggering the gait-training apparatus to retain the training session so that the training intensity can be regulated on-line and the user's muscle can be trained effectively based on the concept of progressive overload.
