| 20090102426 | CHARGING SYSTEM AND METHOD FOR ELECTRONIC DEVICE - A charging system and method for an electronic device are used for controlling an external charging power supply to charge the electronic device. Electric quantity detection software running on the electronic device is used to detect electric quantity of a battery of the electronic device and to generate a signal indicating a message of performing a charging operation or indicating a message of stopping the charging operation. A Universal Serial Bus (USB) interface is disposed in the electronic device to output the signal. A USB control chip, disposed in a charging device, receives the signal and controls a switch to turn on or turn off the external charging power supply to charge or stop charging the electronic device. The charging system and method for an electronic device can effectively control the electric quantity of the battery of the electronic device without requiring a charging control circuit. | 04-23-2009 |
| 20090108809 | CHARGING SYSTEM AND METHOD FOR ELECTRONIC DEVICE CONTROLLED BY AUDIO OUTPUT - A charging system and method for an electronic device controlled by audio output are used for controlling an external charging power supply to charge the electronic device. An electric quantity detection software runs on the electronic device, for detecting an electric quantity of the electronic device and generating audio signals indicating a message of performing a charging operation or a message of stopping the charging operation. An audio output interface is disposed on the electronic device for outputting the audio signals. A decoding device is connected to the audio output interface for receiving the audio signal and controlling the external charging power supply to perform the charging operation or to stop the charging operation on the electronic device. The charging system and method for the electronic device can effectively control the electric quantity of the electronic device, without requiring any charging control circuits. | 04-30-2009 |
| 20090119059 | Position Detecting System and Method for Electronic Device - A position detecting system and method for an electronic device used an audio signal input module of the electronic device and a signal receiver to connect to the audio signal input module convert an external position signal into an audio signal. A position detecting software running on the electronic device analyzes the audio signal. Accordingly, the current position of the electronic device is obtained. The audio signal input module of the electronic device is employed as an input port for the external position signal, thus saving the construction cost of the system. Besides, the current position of the electronic device with an ever-changing position can be obtained during a test process, such that the electronic device can start or stop a test item accordingly. | 05-07-2009 |
| 20090187684 | AUTOMATIC INSPECTION SYSTEM AND METHOD FOR NOTEBOOK COMPUTER KEYBOARD INTERFACE - An automatic inspection system and method for a notebook computer keyboard interface are described. The method includes the following steps including scanning a notebook computer keyboard array to obtain a keyboard position corresponding table; running a testing software in the notebook computer to obtain a position value of a key under test from the keyboard position corresponding table; receiving a testing command from the testing software by an USB interface; constituting a virtual keyboard matrix with at least one matrix switching chip, for controlling the close action of a corresponding key position in the virtual keyboard matrix according to the testing command; transferring the actual key position value corresponding to the output close action to the notebook computer according to the configuration of the notebook computer keyboard interface; and receiving and comparing the actual key position value with the position value of the key under test. | 07-23-2009 |
