A mobile terminal including a display; a wireless communication processor configured to transmit a control signal to a content transmission device; and a controller configured to in response to an input for an execution of a content playback application, display a content playback setting screen on the display including a plurality of content reception devices, a plurality of input terminals of the content transmission device through which the content reception devices are connected to the content transmission device, and a plurality of thumbnail images corresponding to content data input via the respective input terminals, and in response to a selection of a first content reception device among the plurality of content reception devices and a selection of a first input terminal among the plurality of input terminals, transmit the content data received through the first input terminal of the content transmission device to the first content reception device, and in response to a selection of the first content reception device and a selection of a second input terminal among the plurality of input terminals, transmit the content data received through the second input terminal of the content transmission device to the first content reception device.

A network management system for a wireless communications network adaptively selects wireless modems to use in communicating messages between a control system and downhole equipment. The wireless modems are selected based on a monitored signal to noise ratio. The network management system may be centralized within the network or within a surface control system or can be decentralized so that a plurality of the wireless modems can adaptively determine routing in the network. The network management systems can be used in conjunction with a backbone network architecture to achieve further efficiencies in network throughput.

A wireless network connection method for an electronic device is provided, in which a first signal is transmitted to additional electronic device and is utilized to identify the electronic device. When the additional electronic device identifies the electronic device through the first signal, it establishes wireless communication between the electronic device and the additional electronic device. A second signal is transmitted to the additional electronic device. The second signal is an audio signal to instruct the additional electronic device to maintain the wireless communication.

A control device executing a networking framework for controlling a network of smart objects registered with a framework may interact with only those smart objects in a room. A radio frequency signal broadcast on the networking framework for reception by smart objects registered with the networking framework may cause each of the plurality of smart objects to transmit an ultrasound signal that may include an identifier, such as a generic identifier of the smart object that was assigned during registration with the network framework. The control device may receive the ultrasound signals only from the smart objects in the room. The control device may rename each smart object from which ultrasound signals were received with new identifying information that may include a reference to the room. The device may then communicate with the smart objects via the networking framework using the new identifying information.

Embodiments described herein include an acoustic telemetry system for use with an apparatus configured to rotate. The acoustic telemetry system includes one or more sensor nodes and at least one receiver node. In at least one embodiment, the telemetry system also includes at least one hub node positioned on the apparatus. Each sensor node is attached to or embedded in the apparatus. Each sensor node obtains data related to one or more operating conditions of the apparatus and the environment surrounding the apparatus. The one or more sensor nodes encode and transmit the data to the hub node or the receiver node using ultrasonic acoustic waves. In at least one embodiment, the hub node transmits the data to the receiver node. The receiver node decodes the data and monitors the one or more operating conditions of the apparatus.
