    Abstract: A control method of an electrical adjustable table is provided. The control method of the electrical adjustable table includes following steps. Initialize an internal setting value or a user setting value. Enter a static status. Extend or shrink a table foot for adjusting the height of a table plate heading to a first direction according to an operation to a hand control device. Stop adjusting the height of the table plate when a motion sensor unit is used and detects the table plate tilted during adjusting the height of the table plate. The method effectively prevents the table plate to keep lifting when the table plate hits an obstacle to avoid objects fallen, the obstacle damaged or malfunction of the electrical adjustable table.

    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: 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 portable device for controlling an external electrical adjustable apparatus is provided. The portable device comprises a case, a signal transmitter connected to the electrical adjustable apparatus, a tilt sensor sensing a tilted angle, a memory storing a threshold angle and a processor. The processor 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. This present disclosed example can effectively prevent article placing on the carrying structure from falling and prevent the electrical adjustable apparatus or the obstacle from being damaged by continual stretching/shortening after collision.
