摘要： 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.

摘要： A battery management system includes a power converter, a first switch, a second switch, a first detecting unit, and a CPU. The power converter is configured to divide current provided by the power supply into a first and a second output current, according to a working current of a system load in a normal state, the first output current is used to power the system load, and the second output current is used to charge a battery unit. The CPU is configured to determine whether the value of current detected by the first detecting unit is greater than a threshold value, and further controls turning on the first switch to power the system load using the first output current, and turn on the second switch to charge the battery unit using the second output current.

摘要： A scanning circuit includes n column wires, a ground column wire, n row wires, n*n keys, and n diodes. The column wires and the ground column wire cross the n row wires to form n*(n+1) intersections. The ground column wire having a terminal is for being connected to the high voltage source and the other terminal is grounded. A control unit includes n ports electrically connected to the row wires correspondingly. The diodes are set on n intersections of the matrix, and each diode has a positive terminal electrically connected to the corresponding row wire, and a negative terminal electrically connected to the corresponding numbered column wire. The n*n keys are set on the intersections except where the diodes are located, the n*n keys are connected across column wires, the ground column wire, and the n row wires correspondingly. A related method is also provided.

摘要： A method to store point-in-time data, comprising establishing a block size, providing source data storage comprising (S) blocks, and target data storage comprising (T) blocks. The method configures (B) source storage segments and (B) target storage segments, and receives updated point-in-time data for original point-in-time data written to an (i)th source storage segment. The method then determines if a (j)th target storage segment comprises available storage capacity to store the original point-in-time data. If a (j)th target storage segment comprises available storage capacity to store the original point-in-time data, the method writes the original point-in-time data to that (j)th target storage segment.
