Techniques for discovering a device in a wireless network are described herein. For example, a first device may send a network discovery solicitation message to a second device to solicit a communication relationship (e.g., request connection to a parent). The network discovery solicitation may include one or more information elements that indicate a channel function associated with the first device and a listening window during which the first device will be listening for communications. The second device may use the channel function to frequency hop and send a network discovery message to the first device during the listening window. The network discovery message may include one or more information elements to establish a sampled schedule for the first device moving forward.

A remote control apparatus is disclosed. The remote control apparatus comprises: a microphone; a communication unit; a storage unit for storing pattern information of a non-audible sound for identification of the locality of an external electronic device; and a processor for broadcasting, through the communication unit, information acquired on the basis of an ambient sound received through the microphone, and when a non-audible sound based on broadcasted information output from an electronic device is received through the microphone, comparing a pattern of the received non-audible sound with pattern information stored in the storage unit, and transmitting a pairing request signal to the electronic device on the basis of a comparison result.

A method collects data, a physical or physico-chemical parameter and/or an operating state, during operation of a sensor. The sensor contains a measuring element which provides elementary measuring units, which correspond to a physical or physico-chemical variable or the physical or physico-chemical parameter, as raw measurement data, and the sensor has a communication device and a memory. To determine the measurement resolution of the sensor, the conditions for generating time stamps are first determined using a correlation model. Time stamps of successive raw measurement data are generated in the sensor on the basis of the correlation model. The time stamps are transmitted with the result that the raw measurement data acquired by the measuring element are reconstructed and evaluated based on the time stamps using the correlation model. Wherein operating state monitoring of the sensor is carried out by comparing current time stamps with historical and/or empirical time stamps.

The present disclosure discloses a time synchronous hybrid analog and digital sensor data acquisition system and method, comprising analog sensors, digital modules, digital sensors, hubs for networking a plurality of heterogeneous sensors, a local-area network device and a data processing terminal. The present disclosure solves the problem that data cannot be compared due to time difference in acquisition for the reason that the sampling time of different sensors cannot be synchronized precisely in the existing experiments and practical engineering, and also solves the problems of single function, low integration level and manpower consumption when different sensor instruments work separately. The data acquisition system of the present disclosure can be directly connected to various heterogeneous sensors to realize synchronous acquisition, synchronous transmission and simple and fast operation. The present disclosure greatly increases the time precision, amplitude precision and efficiency of synchronous acquisition, reduces the labor cost, and has wide application prospect.
