Abstract: A hot spot defect detecting method and a hot spot defect detecting system are provided. In the method, hot spots are extracted from a design of a semiconductor product to define a hot spot map comprising hot spot groups, wherein local patterns in a same context of the design yielding a same image content are defined as a same hot spot group. During runtime, defect images obtained by an inspection tool performing hot scans on a wafer manufactured with the design are acquired and the hot spot map is aligned to each defect image to locate the hot spot groups. The hot spot defects in each defect image are detected by dynamically mapping the hot spot groups located in each defect image to a plurality of threshold regions and respectively performing automatic thresholding on pixel values of the hot spots of each hot spot group in the corresponding threshold region.

Abstract: A battery safety management procedure applicable to a battery safety management system is provided. The battery safety management system includes a controller, storage, and battery. The battery safety management procedure is stored in the storage and executed by the controller to perform steps of: determining whether a power level of the battery is greater than or equal to a power level threshold and determining whether a power storage time is greater than or equal to a time threshold; and performing a discharging procedure when the power level of the battery is greater than or equal to the power level threshold, and the power storage time is greater than or equal to the time threshold. Time control and power level control prevents the battery from being in a prolonged state of high power level to reduce the chance of battery swelling, leaks, abnormalities, and damage, thereby extending battery service life.

Abstract: A charging method includes detecting whether two battery modules are balanced, simultaneously charging the two battery modules by a first charging current when the two battery modules are balanced, and executing a specific charging procedure when the two battery modules are not balanced. The step of executing the specific charging procedure includes charging by the first charging current a first battery module between the two battery modules that is not balanced and disconnecting the other between the two battery modules, and simultaneously charging the two battery modules by a second charging current upon the first battery module reaching balance, wherein the second charging current is less than the first charging current.

Abstract: A power protection method for an electronic device includes supplying power to an electronic device through a power supply path, detecting a positive current of the power path, detecting a negative current of the power path, comparing a current amount of the positive current with a current amount of the negative current, and disconnecting the power path when the current amount of the positive current is not equal to the current amount of the negative current.

Abstract: A charging method includes calculating a remained lifetime of a battery unit based on a health state and a battery temperature of the battery unit, charging the battery unit by a charging voltage with a first potential when the remained lifetime is higher than a lifetime threshold, and charging the battery unit by the charging voltage with a second potential when the remained lifetime is smaller than or equal to the lifetime threshold.

Abstract: A dynamic cypher authentication system is applied to an electronic device having an authentication password. The system includes an input module, a password triggering module, an operation module, and an authentication module. The input module receives an operator password input by a user. The password triggering module generates a trigger signal and then generates a prompt password according to the trigger signal. The operation module performs a mathematical operation on the prompt password according to the operator password, so as to generate the authentication password. The authentication module receives a login password and compares the login password with the authentication password, so as to determine whether to authorize a login request on the electronic device.
