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.

First claim

What is claimed is:

1. A portable device for controlling an external electrical adjustable apparatus, comprising:
a case;
a signal transmitter installed in the case and connected to the electrical adjustable apparatus;
a tilt sensor sensing a tilted angle;
a memory storing a threshold angle;
a human-machine interface used to receive operation and trigger a raising/lowering-controlling signal;
a standby unit installed in the case and electrically connected to the human-machine interface; and
a processor installed in the case and electrically connected to the signal transmitter, the tilt sensor, the memory, the human-machine interface and the standby unit, the processor being configured to determine that a carrying structure of the electrical adjustable apparatus has collision when receiving the raising/lowering-controlling signal used to control the electrical adjustable apparatus and the tilted angle is not less than the threshold angle, and sending a stopping signal to the electrical adjustable apparatus via the signal transmitter for making the electrical adjustable apparatus stop raising/lowering the carrying structure;
wherein the standby unit forwards the raising/lowering-controlling signal received from the human-machine interface to the processor, and keeps a path between the human-machine interface and the processor conductive for a standby time when failing to receive the raising/lowering-controlling signal.

2. The portable device for controlling the external electrical adjustable apparatus according to claim 1 , wherein the threshold angle is 0.3 degrees.

3. The portable device for controlling the external electrical adjustable apparatus according to claim 1 , wherein the signal transmitter is Bluetooth transmitter, Wi-Fi transmitter or ZigBee transmitter.

4. The portable device for controlling the external electrical adjustable apparatus according to claim 1 , wherein the tilt sensor is gyroscope or accelerometer.

5. The portable device for controlling the external electrical adjustable apparatus according to claim 1 , wherein the standby unit is optical coupler.

6. The portable device for controlling the external electrical adjustable apparatus according to claim 1 , wherein the portable device is smart glasses, smart watch, tablet, smart wristband or smart ring.
