Electronic device with a plurality of charging modes
An electronic device with several charging modes includes a transmission module, a central control module, an interface module, and a power module. The transmission module includes a first connecting terminal for connecting an external electronic product and produces a corresponding identification signal according to each external electronic product. The central control module supplies different power supplies to each external electronic product and produces a corresponding power setting signal. The interface module obtains a different power supply for each external electronic product through the transmitting module and converts each different power supply into a same charging power according to the power setting signal and identification signal. The power is stored in the power module to charge the power module, so that the electronic device just needs a transmitting module to obtain the power from any external electronic product, and thus greatly improve the convenience of charging the electronic device.

A TV set (20) with a function of rejecting telephone calls is provided. The TV set includes a first communication port (201) and a second communication port (210) respectively connected with a telephone network (30) and a telephone (40). A switching circuit (209) is interposed between the first communication port and the second communication port; a decoder (202) is connected to the switching circuit and used for decoding a caller ID of an incoming call from the telephone network and transmitting the decoded caller ID to a display unit (205) to be displayed and to a MCU (203); and the MCU for invoking an automatically rejecting module (208) to automatically rejecting the incoming call by switching off the switching circuit according to rejection information stored in a memory. A related method is also provided.
An electronic book reading apparatus mainly includes a user interface, an operation controlling unit, and a display unit. The user interface allows a user to flip an appropriate number of pages of a displayed electronic book. The user interface includes a plurality of sensing units for generating sensing signals in response to the flipping operations. The operation controlling unit is used for determining a speed and direction of the flipping operations and generating a speed signal and a direction signal according to the sensing signals. The display unit receives the direction signal, flips the appropriate number of pages of the displayed electronic book in a corresponding direction according to the received speed signal and direction signal, and displays the resulting page of the electronic book after flipping. A related method is provided.
A mobile communication device is provided. The mobile communication device includes a processing unit, a battery unit, a solar cell unit, an electronic switch circuit and an analog to digital converter (ADC). In the mobile communication device, the solar cell unit receives a light and thus a luminance and transforms the luminance into an analog voltage. The ADC is configured to convert the analog voltage into a digital voltage. The processing unit is used to transmit a control voltage according to the digital voltage. In response to the control signal, the electronic switch circuit is controlled to turn the solar cell unit on or off and the solar cell unit provides all, a portion or none of a working current required for the processing unit according to the action of the electronic switch circuit. In addition, a luminance value may be generated according to the light received by the solar cell unit so that a user may be aware of the light quality of the ambient environment, thereby preventing himself/herself from reading under a poor light source environment thus protecting his/her eyesight from being damaged.

A present invention provides a PDA with a built-in current limiting device. When powered by a battery, the PDA outputs a current to an external device, wherein the current is within a first current range. When powered by external power through an adapter, the PDA outputs the current to the external device, wherein the current is within a second current range. The first current range is smaller than the second current range. Additionally, a current limiting device built into a PDA is disclosed.
