Abstract: A pairing method for mobile device includes steps of: establishing a wireless communication link between a first mobile device and a second mobile device; configuring the second mobile device to send a second data relating to a second movement of the second mobile device in a specific period; configuring the first mobile device to receive the second data from the second mobile device and determining whether or not the second data is matched with a first data relating to a first movement of the first mobile device in the specific period ; and pairing the first mobile device with the second mobile device if the first data is matched with the second data. A corresponding pairing system for mobile device is also provided.

Abstract: The present invention discloses a light emitting device power supply circuit, a light emitting device control circuit and an identifiable light emitting device circuit therefor, and an identification method thereof. The light emitting device control circuit includes an operation signal generation circuit and an identification circuit. The operation signal generation circuit determines whether the light emitting device control circuit operates in an identified mode or amiss mode according to an enable signal. In the identified mode, the light emitting device control circuit operates a power stage circuit to supply an output current to an identifiable light emitting device circuit. In the miss mode, an output voltage is maintained at a predetermined level. The identification circuit determines whether the light emitting device control circuit switches from the miss mode to the identified mode according to whether the output voltage meets a condition.

Abstract: A method for extra appending data in a multiple layer disc is provided. The capacity of the data zone in the multiple layer disc is fixed, and each layer comprises a plurality of appended sessions. When multiple layer disc is mounted, it is determined whether data is appended in zones following a middle zone. If the data is appended in the zones following the middle zone, a first jump address is obtained from a table of extended contents to serve a start address of appending the data. Data is appended to the multiple layer disc. An end address of appending the data is recorded in the table of extended contents to serve a second jump address for a next appending operation.

Abstract: A method for determining a write type of a disc includes determining whether the disc is a recordable disc or a re-writeable disc, determining whether a lead-in area of the disc comprises a program memory area or not when the disc is a recordable disc or a re-writeable disc, identifying formats of the last two blocks of a track in a closed session of the disc when the lead-in area of the disc comprises the program memory area, and determining the write type of the disc according to the formats of the last two blocks.

Abstract: The invention discloses a method for adjusting the temperature in an optical information reproducing apparatus, including a spindle motor for driving an optical information medium disposed within the optical information reproducing apparatus and a pick-up head unit for retrieving/recording data from/to the optical information recording medium. By the method according to the invention, the temperature in the optical information reproducing apparatus is cooled down by an air flow caused by the rotating optical information recording medium driven by the spindle motor.
