Abstract: A method for deduplication applicable to a file chunked into a plurality of deduplicated chunks is provided and includes: defining a calculation range in the file according to types of the chunks in the file, where the calculation range includes a plurality of consecutive chunks in the file; generating an evaluation value according to the types of the chunks in the calculation range to determine whether to mark the chunks in the calculation range; and re-chunking and deduplicating the marked chunks in the file. A computer-readable medium and a file system corresponding to the method for deduplication are also provided.

Abstract: A method for identifying video signal source is provided. The method includes the following steps. A first identification code is assigned to a first transmitter device by a receiver control unit of a receiver device. A first video data is transmitted by the first transmitter device. The first video data and a first identification image corresponding to the first identification code are combined as a first combined video data by the receiver control unit. The first combined video data is outputted to a display device by the receiver control unit.

Abstract: A portable electronic device includes a main body and a first battery module. The main body includes a base, two first engaging portions respectively disposed on two ends of a side of the base, a casing installed on the base, and a first connecting terminal set disposed on a surface of the casing adjacent to the side of the base and electrically connected to an electronic component. The first battery module includes a first housing whereon a plurality of holes is formed, two first constraining portions for engaging with the corresponding first engaging portions respectively, and a first transmission terminal set for contacting the first connecting terminal set. The portable electronic device further includes a first latch structure. The first latch structure includes a plurality of first hooks for engaging inside the plurality of first holes on the first housing.

Abstract: A backlight module includes a lighting unit including a primary light guiding unit and a light source, and an auxiliary light guiding unit. The light source is disposed at one side of the primary light guiding unit, and emits light toward the primary light guiding unit to be guided thereby for projecting in a first direction. The auxiliary light guiding unit includes a light collecting portion disposed at one side of the lighting unit opposite to the first direction for collecting light leaking from the lighting unit, and a light guiding portion extending generally transversely from one end of the light collecting portion for guiding the light collected by the light collecting portion to emit in a second direction different from the first direction.

Abstract: An OLED display with a current stabilizing device employs a voltage boosting and current stabilizing device which is coupled between the driving-voltage line of the data driver and the data-power-supply wires to produce an output voltage higher than the driving voltage by boosting the driving voltage of the data driver, and then to maintain the current of the OLEDs at a constant level by performing current limiting, so that the problem of the current-ununiformity caused uneven luminance of the conventional OLED display can be solved, and the possibility that the luminance of the OLED panel will decay in a short period of time is reduce.
