Abstract: A slide rail assembly includes a first rail, a second rail, an elastic member, a movable member and an electronic module. The second rail is movable relative to the first rail. When the second rail is located at a retracted position relative to the first rail and when the movable member is in a locking state, the elastic member is configured to be locked to accumulate the elastic force. The electronic module includes a driving device configured to drive the movable member to switch from the locking state to an unlocking state, in order to release the elastic force of the elastic member, such that the second rail is moved from the retracted position along an opening direction relative to the first rail in response to the elastic force of the elastic member.

Abstract: An electronic system is provided. The electronic system includes a processor and a first power management circuit. The processor generates and outputs a first data frame. The first data frame includes at least one first guard bit and a first address. The first power management circuit includes a first register. The first power management circuit receives the first data frame and determines legitimacy of the first address according to the least one first guard bit. In response to that the first address is legal, the power management circuit transmits a first response to the processor and accesses a first region in the first register according to the first address.

Abstract: A lock device adapted for a first object and a second object movable relative to the first object includes a slider, a driving module, a latch and a power module. The driving module can drive the slider to move between a locking position and an unlocking position. The latch is movable relative to the slider. The power module can provide electricity to the driving module. When the second object is located at a retracted position relative to the first object, the driving module can drive the slider to move to the locking position, so that the latch blocks the second object. When the driving module is not driven by the power module, the latch is driven by the second object moving in an opening direction to move from an original state to a non-original state for driving the slider to move from the locking position to the unlocking position.

Abstract: A mechanism is constructed by twelve-axis geometry and controlled by spherical coordinate, so that all torques in twelve axes can be parallelly integrated. Timing belts, pulleys, hollow shafts, and spur gears onto four arc-link sets are included. Via these transmission components, base arc-links can be indirectly but synchronously rotated by base driving modules and terminal arc-links can be indirectly but synchronously rotated by terminal driving modules. The final output torque can be integrated via serial linking and parallel cooperating by the twelve rotating modules. Therefore, four arc-link sets work cooperatively and effectively in group but bear no burden each other. The mechanism can be applied to a multi-axis composite machining center machine or a multi-time element detection measuring bed and shoulder joints or hip joints corresponding to robots.

Abstract: This new invented mechanism is geometrically defined by two concentric tetrahedrons. Four motors are mounted onto the four vertexes of an outer tetrahedron frame. Four outer arc-links which are driven by these motors are pivotally connected with another four inner arc-links which are pivoted by four vertexes of an inner tetrahedron frame. This mechanism not only extends the range in pitch, roll and yaw three rotational DoF for enlarging the limits of Stewart 6-axis motion platform but also increases two translational DoF for improving the shortage of gimbals type multi-ring mechanism. This mechanism can simulate high maneuvering motion (ex. Barrel roll or fast spin) as high-speed vehicles (ex. fighter or roller coaster) can to stimulate passengers with virtual-but-real and shocked-but-exciting sensation. This mechanism will be chosen as a motion platform or a space orientating mechanism for a theme park game machine or a military fighter trainer.

Abstract: A tool includes a working tool portion and an extendable handle joined with the working tool portion. The extendable handle includes a shaft, a tube, and an anti-rotation member that is unbiased so as to prevent, during application of relative rotational force between the shaft and tube, relative rotation between the shaft and tube and to prevent removal of a portion of the anti-rotation member from an axially arranged groove. A lock device is movable from a first position to a second position wherein when the lock device is in the first position the tube is prevented from moving axially relative to the shaft and wherein when the lock device is in the second position the tube can be moved axially relative to the shaft.
