An anti-counterfeiting electronic device includes a function component assigned with an identification code ID and a processor. The processor generates a random code K1 and transmits the random code K1 to the function component; the function component encrypts the random code K1 and the identification code ID to generate a key ID1. The processor further obtains the key ID1 from the function component and decrypts the key ID1 to generate an identification code ID2, and determines whether the identification code ID2 is the same as the ID and executes the system login command if the identification code ID2 is the same as the identification code ID. An anti-counterfeiting method is also provided.

A power switch circuit providing voltage to an output port is provided. The switch circuit includes a single power supply, a switch unit, a controlling unit, and a logic unit. The switch unit is connected between the single power supply and an output port and capable of being turned on and off alternatively for continuing or discontinuing power from the single power supply to the output port; the single power supply provides power to the output port. The controlling unit is configured for generating a voltage controlling signal and transmitting the voltage controlling signal to the logic unit. The logic unit receives and inverts the voltage controlling signal, and outputs the inverted voltage controlling signal to turn on or turn off the switch unit.

A multidimensional display apparatus includes a main display screen divided into at least three display areas including a first centre display area and at least two surrounded display areas, at least two reflective elements, and at least three display surfaces. The reflective elements are arranged above and inclined with respect to the second display areas, and a reflection surface of each of the reflective elements faces the corresponding second display area. One of the display surfaces is above the first display area, and the other two are corresponding to the second display areas, facing the reflection surfaces of the reflective elements. The contents displayed on the first display area is viewable on the display surface above, and the contents displayed on the second display areas are reflected by the corresponding reflection surfaces of the reflective elements and viewable on the other two display surfaces.

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:
An under-voltage protection circuit has a power input terminal connected to a battery, a power output terminal connected to an electronic device, a switch circuit for switching the power supply circuit from the power input terminal to the power output terminal, a control circuit for controlling the switch circuit, and a control voltage generating circuit that generates a first control voltage when the switch circuit is cut off. The control circuit controls the switch circuit in accordance with the first control voltage. The control voltage generating circuit further generates a second control voltage when the switch circuit is conductive, and then the control circuit controls the switch circuit in accordance with the second control voltage.
