Abstract: A dustproof device is provided for use with a ball screw which includes a screw rod and a nut mounted around the screw rod. The dustproof device includes an annular body and an elastic valve plate. The annular body is disposed inside the nut and penetrated by the screw rod and has an outer annular surface provided with a debris exit. The debris exit has one end in communication with a spiral passage formed between the screw rod and the nut. The elastic valve plate, which is provided at the opposite end of the debris exit of the annular body, can be pushed open by a fluid and thus opens the debris exit, allowing the debris generated by the ball screw to be discharged through the debris exit along with the fluid, thereby contributing to extending the service life of the ball screw.

Abstract: A method of detecting a preload of a linear guide includes: applying an external force to the linear guide with an external force applying device, wherein the external force applying device sends an impact signal while applying the external force; sensing with a sensor a vibration signal sent from the linear guide because of vibration thereof which occurs under the external force; and receiving the impact signal of the external force applying device and the vibration signal of the sensor and calculating the preload of the linear guide according to a received result, with a signal analyzer. Therefore, with the method of the present invention, the preload of the linear guide is precisely tested regardless of environmental factors.

Abstract: A multidirectional foot controller includes a base, a first platform, a second platform, and two pedals successively stacked and assembled together. The multidirectional foot controller is activated by having the two pedals depressed simultaneously, and then controls an externally connected endoscope to move forward or backward by a first platform, or controls the endoscope to move leftward or rightward by a second platform. By having only one of the pedals depressed, the multidirectional foot controller can change the field of view of the endoscope.

Abstract: A linear actuator includes a linear module including a base, a screw rod mounted in the base and a transmission carriage threaded onto the screw rod, and a support module including two support carriages movably mounted on the screw rod at two opposite sides relative to the transmission carriage, a protective cover disposed at one side of the base and connected to the two support carriages, two pulley blocks mounted at the two opposite ends of the protective cover and a cable wound round the pulleys of the pulley blocks and connected to the transmission carriage and the base by a respective cable connection plate. Thus, the transmission carriage utilizes the cable to carry one pulley block and then the protective cover, causing the protective cover to carry the two support carriages and the other pulley block, achieving the effect of supporting the screw rod.

Abstract: A flexible bearing including spacers is provided. The flexible bearing includes: an outer race including a rolling groove; an inner race arranged in the outer race and including a rolling trough corresponding the rolling groove to collectively define a loading passage; rolling elements arranged in the loading passage; and spacers each including a retention section for receiving and retaining the rolling elements. Two adjacent ones of the spacers are in contact engagement with each other with end faces thereof and the two end faces are respectively a concave surface and a convex surface. The concave surface and the convex surface of the spacers are allowed to undergo relative sliding so as to allow the spacers to adjust, with respect to each other, an angular position thereof during an operation of the flexible bearing in order to prevent the spacers from interfering with the outer race or the inner race.

Abstract: A lower limb spasticity measurement method includes the step of setting the lower limbs of the person in a lower limb orthotic device of a gait activity machine, the step of starting up a motor of the gait activity machine to drive the lower limb orthotic device for lower limb activity, the step of getting a statistical distribution data from the output torque of the motor within a predetermined time and then calculating the statistical distribution data to obtain a threshold, and the step of determining whether the output torque of the motor is greater than the threshold or not, and then stopping motor if the output torque of the motor is greater than the threshold. Thus, the method of the invention can accurately measures spasticity in the lower limbs of a person without the use of sensors, effectively saving the cost of equipment.

Abstract: A threadless linear guide includes a rail, a slide block, a recirculation assembly, and a fixing member. The slide block, the recirculation assembly, and the fixing member are positionable with respect to each other through retention engagements therebetween so that the components can be coupled to each other without screws. A reinforcement plate is provided for reinforcing the strength of the recirculation assembly for the recirculation assembly is generally formed of injecting molding, while the fixing member and the reinforcement plate are made of metal. Thus, with the fixing member and the reinforcement plate enclosing the recirculation assembly, any foreign object jamming in the interior would not cause the rolling bodies to eject out through the recirculation assembly during the operation of rolling bodies.

Abstract: An electric gripper system includes a motor driving a gripper mechanism, a sensor, and a controller. The sensor is assembled onto the motor for generating a current position of the gripper mechanism. The controller has a control segment, a transceiver segment, an accessible segment, and a driving segment. The control segment generates a target position according to a relative-position command value of the transceiver segment and an absolute cumulative position of the accessible segment. The control segment generates a driving datum based on a difference between the current position and the target position, and on a rotation rate of the motor. The driving segment uses the driving datum to drive the motor to move the gripper mechanism. With calculation among the relative-position command value, the absolute cumulative position, and the current position, the motor is prevented from accumulating positional deviation.
