Abstract: A touch input device includes a primary touch panel, a primary touch driver, an environment compensation unit, a processor, and an operation module. The primary touch panel generates a first change of electric charge distribution according to a touch on the primary touch panel from a user. The primary touch driver generates a touch signal according to the first change of electric charge distribution to the primary touch panel. The environment compensation unit detects a second change of electric charge distribution of an environment and generates a compensating signal. The processor processes the touch signal and the compensating signal to produce a reliable touch signal. The operation module performs a function according to the reliable touch signal.

Abstract: A burning system includes an indentifying module, a dividing module, a calculating module, an index module, and a burning module. The identifying module identifies bad blocks of the flash memory. The dividing module reads all blocks of the flash memory in sequence, and when one or more continuous blocks being read are bad blocks, groups the bad blocks and the previously read good block as a storage sector. The calculating module calculates a bad block ratio of each storage sector. The index module assigns a priority level to each storage sector according to the bad block ratio of the storage sector, and associates each priority level of the storage sectors with a start address. The burning module accesses the storage sectors in an order of the priority levels of the storage sectors, and begins writing programs into the storage sectors from the associated start addresses.

Abstract: The electronic device and a preventing data loss method adapted for an electronic device are disclosed. The electronic device includes a storage unit to store an application. The method includes the steps: running an application in response to user input. Detecting the user input in real time and starting to time when the user input is not detected, and evaluating whether the period timed reaches a predetermined time period. If the predetermined time period is elapsed, suspending the application and detecting an electric energy of a battery providing power to the electronic device; evaluating whether the electric energy of the battery reaches a preset value. If the electric energy of the battery reaches the preset value, making a backup of process data associated with the suspended application in the storage unit.

Abstract: A portable electronic device includes an input unit, an audio processing unit, a low pass filter, and at least one vibrator. The input unit is configured to generate operation signals in response to user inputs. The audio processing unit is configured to retrieve an audio file when an operation signal from the input unit for playing the audio file is received, decode the audio file, and convert the decoded audio file to analog audio signals. The low pass filter is configured to transmit analog audio signals with heavy bass to at least one vibrator. The at least one vibrator is configured to create physical vibration in response to the analog audio signals with heavy bass to physical vibration.

Abstract: An audio device includes a headphone jack to receive a headphone plug, an audio output unit connected to the headphone jack, a detecting unit, and a control unit. The detecting unit detects insertion of a headphone plug into the headphone jack when playing an audio file. The control unit directly decreases an output power of the output unit to a first preset value within a preset period in response to the detected insertion of a headphone plug into the headphone jack, and gradually increases the output power of the output unit to a second preset value after the preset period is elapsed. A related method is also provided.

Abstract: An audio device includes a headphone jack to receive a headphone plug, an audio output unit connected to the headphone jack, a detecting unit, and a control unit. The detecting unit detects insertion or removal of a headphone plug from the headphone jack. The control unit decreases an output power of the audio output unit to a preset value within a preset period in response to the detected insertion or removal of the headphone plug, and recovers the output power of the output unit to an original value after the preset period is elapsed. A related method is also provided.
