Abstract: A mobile communication device with replaceable function modules includes a main body and an externally connected device. The main body serves as a central member, and has a main hybrid joint including an electrical contact and a magnetic joint. The main hybrid joint of the main body is joined to a device hybrid joint of the externally connected device, so as to realize the function thereof.

Abstract: The present invention is a circuit that is set in a communication apparatus. The circuit is co-operated with a button of an audio receiving/transmitting device for triggering an on-hook or off-hook function when the communication apparatus receives an incoming call. The button is normally closed. The on-hook and off-hook functions are triggered by a triggering signal which is higher than a threshold value. Thus, the present invention doesn't execute the on-hook or off-hook function by an on/off button set in the communication apparatus but directly execute the button set in the audio receiving/transmitting device, which improved the convenience of the communication apparatus.

Abstract: A method of updating firmware of a circuit module includes providing a switch for selectively connecting the circuit module to a computing system and an update module. The circuit module enters a reset mode and an input/output pin of the circuit module switches to an input mode in response to power being supplied to the circuit module. The input/output pin is pulled to a first digital logic value, which controls the switch to connect the circuit module to the update module. While the circuit module is in the reset mode, the circuit module receives updated firmware from the update module. Then the circuit module enters a normal operation mode and switches the input/output pin to an output mode for outputting a second digital logic value. When the input/output pin outputs the second digital logic value, the input/output pin controls the switch to connect the circuit module to the computing system.
