Abstract: A wireless communication method is provided. The method includes sending, by a wireless communication device, a broadcast message to a terminal device. The broadcast message may include device identification information of the wireless communication device. The method may further include receiving, by the wireless communication device, a scan request message sent by the terminal device. The method may further include sending, by the wireless communication device, a scan response message to the terminal device in response to receiving the scan request message. The scan response message may include attribute data associated with the wireless communication device, and the attribute data may include identification information of content associated with a physical location of the wireless communication device.

Abstract: Systems and methods are provided for providing information associated with media contents are provided. The method comprises broadcasting a communication address associated with a playing device configured to play the media contents, the broadcasted communication address enables a user terminal device to communicate with the playing device; receiving, from the user terminal device, a request to acquire information associated with the media contents; determining an identifier associated with the information; and transmitting the identifier to the user terminal device. The identifier enables the user terminal device to acquire the information.

Abstract: An automatic auxiliary workover rig includes a silo body arranged on a skid-mounted baseplate, a guide-roller type elevator, a random-folding type traveling block rigid guide device, a truck-mounted folding type manipulator, a slip, a flatcar up-down adjustment device, a detecting and conveying device, and a transfer device. The automatic auxiliary workover rig cooperates with an existing workover rig to complete ascending and descending of a sucker rod of an oil pipe during minor overhaul. The slip is located above a wellhead blowout preventer, and is configured to clamp and loosen the oil pipe of a wellhead. The silo body is configured to store and output the oil pipe. The truck-mounted folding type oil pipe manipulator garbs the oil pipe and then ascend and descend the oil pipe, meanwhile the manipulator is equipped with a height adjusting device to realize flexible joint in tube thread fastening and unfastening.
