Abstract:
An unmanned aerial vehicle (UAV) flying method for helping an UAV flying to a location of an owner of the UAV or flying to a predetermined place includes the following steps of: triggering the UAV into a hijacked mode; ascertaining if the UAV is capable of flying or not; the UAV flying to the location of the owner or to the predetermined place if the UAV is capable of flying; and, the UAV sending a distress signal to the owner if the UAV is not capable of flying. Therefore, the UAV is capable of flying back or sending information after entering the hijacked mode, so as to avoid or lower the loss caused by losing the UAV or the UAV being captured by the captor.

Abstract:
A matching method between a wearable smart device and a terminal is disclosed, in which the wearable smart device is disposed with a plurality of LEDs. The matching method includes: the terminal triggering the designated wearable smart device to generate an emitting status for each of the LEDs; and the terminal displaying an interactive interface for a user to input the emitting status of each of the LEDs, in which when the emitting status of each of the LEDs inputted by the user is the same as the emitting status of each of the LEDs triggered by the terminal, a communication connection is established between the terminal and the designated wearable smart device. A matching system is disclosed herein as well.
Abstract:
A method for watching high-definition cable TV programs includes: a blue-tooth learning remote controller learning remote-controller controlling instructions of a high-definition cable TV set top box, and uploading the learned instructions to a smart terminal such that the smart terminal controls the high-definition cable TV set top box; the smart terminal controlling the high-definition cable TV set top box to choose high-definition cable TV programs; the high-definition cable TV set top box outputting a HDMI signal; the smart TV dongle receiving the HDMI signal, and outputting the HDMI signal to a high-definition TV; the smart TV dongle performing an encoding and a packing on the HDMI signal and then transmitting the packed signal to the smart terminal by using a wireless manner; and the smart terminal performing a de-packing and a decoding on the received signal and then playing the decoded signal on the smart terminal.
Abstract:
A Zigbee network system comprises a backup Zigbee coordinator, a Zigbee coordinator, and at least a router, and the network group data is instantly copied to the backup Zigbee coordinator. In this way, the backup Zigbee coordinator can replace the broken Zigbee coordinator, so that there is no need to restart the Zigbee network system. Accordingly, user can seamlessly transmit the data through the Zigbee network system without the influence of the broken Zigbee coordinator.
Abstract:
An unmanned vehicle includes a vehicle body and at least one arm assembly. The arm assembly is coupled to the vehicle body. The arm assembly includes a first rotating member, a second rotating member, and a propeller. The second rotating member is coupled to the first rotating member. The propeller includes a propeller rim encircling an outer edge of the propeller and a rotatable axle coupled to the second rotating member. The the rotatable axle extends along a rotating axis. The second rotating member is configured to turn the propeller by rotating the rotatable axle about the rotating axis. The first rotating member is configured to rotate and effect a movement of the second rotating member so as to selectively adjust the rotatable axle to align the rotating axis at least with a first axial direction and a second axial direction.
Abstract:

Abstract:
A solid object manufacturing system comprises: a controlling device, a solid object manufacturing device and a projecting device. The control device generates a solid object model and then divides the model into a plurality of layer images. The control device then adjusts the height of a lifting table of the solid object manufacturing device and controls the projecting device to project one of the layer images on the lifting table synchronously, so as to guide user to form an article by using a printing module of the solid object manufacturing device. The solid object manufacturing system guides user to complete the article by projecting the layer images and adjusting the height of the lifting table.
