    Abstract: An actuator with switchable releasing speed includes an actuation rod, a screw, and a motor. The motor drives the screw rotating so that the actuation rod axially moves relative to the screw. The motor includes a stator, a rotor, a plurality of commutators, and at least three brushes. The at least three brushes have a positive brush, a negative brush, and at least one auxiliary brush. The positive brush is connected to a positive DC voltage. One of the negative brush and the least one auxiliary brush is adjusted to connect to a negative DC voltage so as to change a rotational speed of the rotor, thereby controlling a movement speed of the actuation rod. Accordingly, the releasing speed of the actuator is switchable.

    Abstract: A liftable table foot frame (1) that is easily assembled includes a horizontal frame body (10), a post (20), a side wing (30) and a linking mechanism (40). The horizontal frame body (10) includes a horizontal rod (11). One end of the post (20) pivotally connects to the horizontal rod (11). The side wing (30) includes a plate body (31) and inserting blocks (32) connected to the plate body (31). The inserting blocks (32) separately couple with an end of the horizontal rod (11). The linking mechanism (40) connects the post (20) and the side wing (30). When the post (20) is turned out relative to the horizontal rod (11), the inserting blocks (32) are driven toward the horizontal rod (11) through the linking mechanism (40) to tense and position. Thus, easiness and convenience of assembling can be increased.

    Abstract: A portable device for controlling an external electrical adjustable apparatus is provided. The portable device has a case, a signal transmitter connected to the electrical adjustable apparatus, a tilt sensor sensing a tilted angle and a controlling operation, a memory storing a threshold angle and a processor. The processor generates a controlling signal according to the controlling operation, and transmitting the controlling signal to an electrical adjustable apparatus for making the electrical adjustable apparatus raise/lower. The processor further determines that the electrical adjustable apparatus has collision when receiving a controlling signal used to control the electrical adjustable apparatus and the tilted angle is not less than the threshold angle, and sends a stopping signal to the electrical adjustable apparatus via the signal transmitter for making the electrical adjustable apparatus stop raising/lowering when determining that the electrical adjustable apparatus has collision.
