    摘要： Aspects concern a system and method for determining a state of an electronic device comprising a processor arranged in wireless signal communication with the electronic device to obtain a first wireless signal associated with the electronic device, convert the first wireless signal to a first signal measurement, and compare the first signal measurement with a first threshold; wherein if the first signal measurement is less than the first threshold, the processor is operable to obtain a plurality of successive wireless signals associated with the first wireless signal and corresponding signal measurements over a predetermined period to determine a gradient measure, and if the gradient measure is negative over the predetermined period, the processor determines that the electronic device is in a first state.

    摘要： A device control method is disclosed. The method is applied to a communication system, and the communication system includes a first device, a second device, and a third device. The first device, the second device, and the third device communicate with each other by using a near field communication technology. The method includes: The second device sends a first message, where the first message carries an identity of the second device; the third device sends a second message, where the second message carries an identity of the third device; the first device determines an angle of arrival AOA of a signal of the second device based on the received first message; the first device determines an AOA of a signal of the third device based on the received second message; the first device sends a third message to the second device based on the AOA of the signal of the second device and the AOA of the signal of the third device; and the second device performs a response operation in response to the received third message. Embodiments of this application can implement coordinated control for a plurality of devices through a simple operation, thereby effectively improving user experience.

    摘要： A two-way signal positioning method and a two-way signal positioning system thereof are disclosed. The method includes the following steps: controlling a locating device to be measured to transmit a plurality of positioning signals of a plurality of transmission powers; causing a plurality of known locating devices to receive the plurality of positioning signals and return a plurality of response signals to the locating device to be measured; recording the strengths of the plurality of positioning signals, the strengths of the plurality of response signals, the plurality of corresponding receiving times and the coordinates of the plurality of known locating devices to a database; identifying the known locating devices corresponding to the stronger signals; and obtaining a signal strength-distance function and a signal strength-distance standard deviation function from the database so as to identify the device location of the locating device to be measured.

    摘要： The invention relates to monitoring of a data centre, in particular through use of measurements from signals received by multiple receivers at multiple locations from sensors distributed throughout the data centre. Example embodiments include a computer-implemented method of monitoring a data centre (110) comprising a plurality of sensors (101a-d) and a plurality of receiver hubs (102a-c), each receiver hub (102a-c) configured to receive radio signal packets from each of the plurality of sensors (101a-d), the method comprising: determining for each sensor (101a-d) an array of parameters derived from the radio signals packets received by each hub (102a-c); determining a change over time in the array of parameters for each sensor (101a-d); and providing an alert if the change over time for one or more of the plurality of sensors (lOla-d) exceeds a predetermined threshold.
