    Abstract: A protection circuit for protecting a rechargeable battery is provided. The protection circuit includes a voltage-threshold generating unit and a comparing unit. The voltage-threshold generating unit is for generating a threshold voltage. The comparing unit is for comparing the threshold voltage to the rechargeable battery voltage and outputting a charging enable signal or a charging disable signal according to the comparison result. The comparing unit outputs the charging enable signal if the amplitude of the threshold voltage is lower than that of the rechargeable battery, or outputs the charging disable signal as the amplitude of the threshold voltage is equal to or higher than that of the rechargeable battery. A battery charger apparatus using the protection circuit is also provided.

    Abstract: The static and dynamic characteristics of smoke are developed for extracting smoke pixels of an image and effective smoke detection. In static characteristic, a chromaticity-based analysis is employed to extract grayish pixels in the moving region from a monitored area. Then, a circumference-based disorder measurement in dynamic characteristic is developed to obtain the smoke pixels from the grayish pixels. To enhance the reliability of alarming, a fuzzy system is introduced to judge if the smoke will spread out by checking its growth-rate.
