A handheld device with switchable signal receiving modes includes a telescopic antenna, a telecommunication transceiver module, a satellite signal module, and a switch circuit. Upon receiving a switch signal, the switch circuit couples the telescopic antenna to the telecommunication transceiver module, and adjusts the telescopic antenna to a first length, so that the telecommunication transceiver module transmits and receives a signal of a first frequency, or the switch circuit adjusts the telescopic antenna to a second length, so that the telecommunication transceiver module transmits and receives a signal of a second frequency. Alternatively, the switch circuit couples the telescopic antenna to the satellite signal module, and adjusts the telescopic antenna to the second length, so that the satellite signal module receives a satellite signal. Thereby, the handheld device can receive signals of various frequencies via one antenna, so that different functional modules transmit and receive signals of different frequencies.

A handheld device with a fast-charging capability is adapted to be connected to a charger to obtain an electric power. The handheld device includes a battery, a charging circuit, a safety circuit, a control unit, and an input module. The charging circuit is electrically connected to the charger and transfers an electric power to the battery. The safety circuit is used for restricting an upper limit of the electric power transferred by the charging circuit. The input module is provided for a user to input an emergency charge command. Upon receiving the emergency charge command, the control unit instructs the safety circuit to lower the restriction on the charging circuit, so as to raise the upper limit of the electric power that can be obtained by the charging circuit, thereby accelerating the charging of the battery.

The invention discloses a connector, which includes a first connecting unit, a second connecting unit, a third connecting unit, and a determining unit. Moreover, the first connecting unit is capable of being electrically connected to a first power source and/or a first data source; and the second connecting unit is capable of being electrically connected to a second power source and/or a second data source. Additionally, the determining unit is electrically connected to the first connecting unit and the second connecting unit respectively, for selectively outputting a data signal and/or a power signal based on a connecting status. Furthermore, the third connecting unit is electrically connected to the determining unit and an electronic device, for transmitting the data signal and/or the power signal from the determining unit to the electronic device.

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.

A dual-mode touch input apparatus, mounted in an electronic apparatus and capable of arbitrarily switching around a 1-D input mode and a 2-D input mode, comprises a touch pad, a flexible printed circuit board (FPCB) and a control chip. The FPCB is used for detecting a position of a user touch and issuing a detection signal to the control chip. The control chip is used for determining whether the dual-mode touch input apparatus is at the 1-D input mode or the 2-D input mode and producing a cursor signal in response to the user touch to control movement of a cursor on a screen of the electronic apparatus.
