Abstract: A bicycle security apparatus includes a housing standing on a supporting plane (ground), at least one drive device disposed in the housing, at least one latch connected to the drive device and a control unit mounted onto the housing. The latch is reciprocally rotated by the drive device to achieve the locked condition and the unlocked condition. The control unit can recognize the identity of the operator such that a man with fraudulent intentions can not steal a bicycle from the bicycle security apparatus.

The basic input output system chip stores basic input output system program and includes a write protection pin and a plurality of status registers. The main control chip includes a plurality of general purpose input output pins. One general purpose input output pin is electrically connected to the write protection pin of the basic input output system chip, the voltage level of the general purpose input output pin is controlled by performing different command programs of the basic input output system program, and the status registers and the basic input output system chip are selectable to be in a write protection mode or a writable mode under the control of the voltage level of the write protection pin of the basic input output system chip.

Abstract: A computer having a BIOS recovery function includes a baseboard management controller (BMC) circuit, a main control circuit, a switching module and a BIOS chip. The switching module is connected to the BMC circuit and the main control circuit. The BIOS chip stores BIOS programs for the computer and is selectively connected to the BMC circuit and main control circuit by the switching module. When the BIOS programs are corrupted, the switching module selects the BMC circuit to communicate with the BIOS chip. New BIOS programs can be sent to the BIOS chip to update the corrupted BIOS programs.

Abstract: An automatic bike locking charging machine is provided.

Abstract: An apparatus for regulating temperature of a central processing unit (CPU) (10) includes a temperature sensor (11), a timer interruption generator (12), a timer interruption processing module (13), and a temperature monitor (14). The temperature sensor is used for obtaining a current temperature of the CPU, and transforming the current temperature into corresponding temperature parameters. The timer interruption generator is used for setting a time interval, and generating a timer interruption signal at each time interval. The timer interruption processing module is used for calculating an appropriate temperature value according to the temperature parameters from the temperature sensor when the timer interruption signal is received from the timer interruption generator. The temperature monitor is used for automatically regulating the current temperature of the CPU according to the calculated temperature value. A related method is also disclosed.
