  • Publication number: 20220113718
    Abstract: A cabinet with filter life prediction function and a method of predicting filter life are provided. The cabinet has an airflow module generating airflow flowing through a filter module. An air quality sensor continuously monitors the air quality sensing value of the airflow and records the sensed value in association with the sensing time. A regression analysis is performed based on the record data to obtain a regression model when a modeling condition is met. When a prediction condition is met, a time period for the currently sensed value to decrease to a threshold is calculated to be a predicted remaining life of the filter module. A notification is generated when the predicted remaining life of the filter module is less than a life threshold.

  • Patent number: 8061152
    Abstract: A wind speed detecting circuit includes a heating unit, a first temperature sensor, a second temperature sensor, a control unit and a driving unit. The first temperature sensor detects a first temperature of an internal portion of an electronic device, thereby generating a first detecting signal. The second temperature sensor detects a second temperature of the heating unit, thereby generating a second detecting signal. The control unit generates a modulation signal according to the first detecting signal and the second detecting signal. In response to the modulation signal, the driving unit generates a driving signal to control operations of the heating unit, so that a temperature difference between the first temperature and the second temperature is maintained constant. A specified relation between the wind speed and the modulation signal facilitates discriminating whether a dust-proof element of the electronic device needs to be replaced.
