Abstract: A linear guideway includes a rail, a sliding block with two foot members, a circulating member with two receiving chambers, two sets of balls and two lubricating plates. The receiving chambers of the circulating member receive the foot members of the sliding block respectively, so that the rail, each foot member of the sliding block and the circulating member form a circulation channel for one respective set of balls to run. The two lubricating plates are adjacent to the two circulation channels and contact the two sets of balls to provide lubrication to the balls. In this way, the linear guideway conceals two lubricating plates in the sliding block, which can maintain the length of the sliding block without affecting the stroke, and ensure that the running path does not produce a step difference, so that the smooth running of the ball can be kept consistent.

Abstract: A linear transmission device includes a screw, a moving member, a return element, and a sensor. The moving member is set in the screw to form a load path therebetween. The return element is set in the moving member and has a return path connected to the load path. The return path and the load path constitute a circulating path for balls to run. The moving member has an internal thread with an ineffective thread section. The moving member has a receiving groove adjacent to the ineffective thread section. The sensor is embedded in the receiving groove of the moving member without affecting the operation of the balls. Thus, the linear transmission device of the present invention can solve the problem of the sensor protruding from the moving member, so that the configuration of the surrounding space and the stroke of the moving member will not be affected.

Abstract: A device and a method for detecting states of a linear guideway including a sliding block and a slide rail are provided. The device includes a sensor located at a position corresponding to a side surface of the slide rail, and an analysis processer communicated with the sensor. The sensor detects the vibrating of the slide rail to generate a sensing signal. The analysis processer compares the sensing signal with at least one threshold, to determines occurrence of abnormalities. Therefore, the sensitivity for detection may be increased.

Abstract: A method for assessing preload degradation of a ball screw is to be implemented by a computer device. The method includes: obtaining an entry of time-domain vibration data based on a vibration signal which is related to vibrations of balls of the ball screw; obtaining an entry of frequency-domain vibration derived data based on the time-domain vibration data; obtaining a vibration eigenvector based on the entry of frequency-domain vibration derived data; performing preload assessment based on the vibration eigenvector, reference vibration vectors and a preload assessment range to obtain a result of the preload assessment; and determining whether preload degradation has occurred on the ball screw based on the result of the preload assessment.

Abstract: An adaptive active training system includes a motion module, a sensing module and a control module. The motion module includes a training unit and a motor connected to the training unit. The motor is configured to bring the training unit to move along a motion trajectory. The sensing module is configured to sense a physiological signal of a user when the user uses the training unit. The control module is connected to the motion module and the sensing module. The control module is configured to calculate a position of the training unit on the motion trajectory, obtain a threshold value corresponding to the position based on a motion model, and determine whether a magnitude of the physiological signal is greater than the threshold value.

Abstract: A clamping device includes a support base, a handle pivoted to the support base, a clamping unit including an upper jaw, a lower jaw and a slide respectively mounted in the support base, and a locking unit including a stop block and a locking bar respectively mounted in the support base. When the handle is pressed, the locking bar is driven to unlock the stop block for allowing movement of the slide, and then the slide is pushed by the handle to lift the lower jaw, causing the upper jaw and the lower jar block to clamp a side rail of an operating bed. When the handle is returned, the stop block is locked by the locking bar, so that the slide is positioned to prevent accidental loosening.
