Abstract: A method for identifying actions of an electric equipment is provided. The method includes: measuring a utility power signal of the electric equipment during a period of time; analyzing a waveform characteristic of the utility power signal in the period of time to acquire a set of characteristic values, and identifying a current control procedure corresponding to the utility power signal from a set of control procedures according to the set of characteristic values, the current control procedure including one or more action stages whose first action stage corresponds to a first action parameter; determining whether a deviation between the waveform characteristic of the utility power signal corresponding to the first action stage and the first action parameter is within a tolerance range; triggering a warning event when the deviation between the waveform characteristic of the utility power signal and the first action parameter is outside the tolerance range.
Abstract: A brewing quality measuring device including an electronic scale, a thermometer, a position maintaining device and an operating/control unit is provided. The electronic scale includes a platform used for placing a container having a brew therein. The thermometer has a measuring portion. The position maintaining device is used for holding the measuring portion of the thermometer at a measuring position. The operating/control unit is used for receiving measuring signals from each of the electronic scale and the thermometer. The measuring position corresponds to a specific position of the container when the container is placed on the platform, so that the thermometer measures the temperature of the brew at the measuring position.
