A diplexer includes a first filter circuit, and a second filter circuit. The first filter circuit is coupled to a first port for providing a first signal path for a first radio frequency (RF) signal. The second filter circuit is coupled to the first port for providing a second signal path for a second RF signal. The first filter circuit includes a first tunable resonant circuit for tuning a first transmission zero corresponding to a first frequency multiplication of the first RF signal. The second filter circuit includes a second tunable resonant circuit for tuning a first transmission zero corresponding to a first frequency multiplication of the second RF signal. The first frequency multiplication of the first RF signal corresponding to the first filter circuit is a fourth harmonic of the first RF signal.

A battery management system for a main system of an electronic device is provided. The battery management system is electrically connected with plural battery units. The battery management system includes plural insertion slots and a battery detachment protection device. The insertion slots electrically connected with the main system. The plural battery units are docked with the corresponding insertion slots. The battery detachment protection device is electrically connected with the main system. When an external force is applied to the battery detachment protection device, the battery detachment protection device generates a system protection sensing signal. In response to the system protection sensing signal, a power supply condition of at least one battery unit in the corresponding insertion slot is adjusted, and the at least one battery unit in the corresponding insertion slot is permitted to be detached from the corresponding insertion slot or positioned in the corresponding insertion slot.

An electronic lock includes a base, an electromagnetic mechanism, a connecting mechanism, a clamping mechanism and a magnetically-attractable plate. The base has an opening. The electromagnetic mechanism has a protrusion block. The electromagnetic mechanism is installed within the base. The protrusion block is penetrated through the opening and exposed outside the base. The connecting mechanism is connected with a rear cover. The clamping mechanism is arranged between the connecting mechanism and the electromagnetic mechanism. Moreover, the magnetically-attractable plate is connected with the clamping mechanism. When the electromagnetic mechanism is electrically conducted to generate a magnetic attraction force, the magnetically-attractable plate is attracted by the magnetic attraction force, so that the clamping mechanism is attracted on the electromagnetic mechanism. By pushing the protrusion block of the electromagnetic mechanism, the clamping mechanism is correspondingly moved and disengaged from the connecting mechanism.
