    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 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.

    Abstract: A linear actuator includes a housing, motors, actuator members, clutch members, a base, a clutch driver, and a pulling handle. The motors are disposed in the housing. The actuator members are respectively disposed in the housing and corresponding to a respective one of the motors. Each clutch member is connected between a respective one of the motors and a respective corresponding one of the actuator members. The base is disposed on an outer surface of the housing, a flange is disposed on an outer surface of the base, and a guiding slot is formed on the base. The clutch driver is in the base and connected to each of the clutch members. A cam contacting against the flange is formed on an end of the pulling handle, and a shaft is inserted through the end. The shaft is inserted through the guiding slot to connect the clutch driver.
