摘要： A method for estimating an operational parameter of a motor is to be implemented by an estimating device. In the method, the estimating device is configured to: receive an acoustic signal attributed to operation of the motor; process the acoustic signal to obtain a plurality of sample points in the frequency domain, each of which has a frequency and a corresponding amplitude; compute an estimated peak frequency using a centroid method based upon the frequencies and the amplitudes; from a plurality of peak frequencies and a plurality of known values of the operational parameter corresponding respectively to the peak frequencies, select a part of the peak frequencies approximate to the estimated peak frequency and a corresponding part of the known values of the operational parameter; and compute an estimated value of the operational parameter based upon the peak frequencies and the known values of the operational parameter.

摘要： A method of reducing energy consumption is to be performed by a network node, and includes configuring the network node to perform the consecutive steps of: b1) setting an initial value for each of first and second parameters; b2) skipping to step b5) if the second parameter is smaller than a random value; b3) estimating an amount of energy required for, and computing a probability of, data transmission therefrom; b4) selecting one of other network nodes corresponding to a greatest value of the first parameter for serving as a transmission route; b5) determining whether data transmitted thereby has reached a destination network node, and skipping to step b7) if affirmative; b6) updating the first parameters of the other network nodes, and returning to step b2); and b7) updating the first parameters of the network nodes belonging to an optimal route.
