Abstract: A fixation module is disclosed, which is disposed in a groove at a corner of an electronic device casing. The fixation module includes a buckle and a fixation element with both ends serving as a first elastic fixation portion and a second elastic fixation portion respectively. A junction is disposed between the first elastic fixation portion and the second elastic fixation portion and connected to the buckle. The first elastic fixation portion and the second elastic fixation portion are clamped at a position corresponding to the junction, so as to keep a relative distance between the first elastic fixation portion and the second elastic fixation portion smaller than an interval between two opposite ends of the groove. By utilizing an elastic restoring force between the first elastic fixation portion and the second elastic fixation portion, the fixation element can be engaged onto a sidewall of the groove.

Abstract: A portable electronic device set is disclosed and includes a portable electronic device and an auxiliary assembly. The portable electronic device has an operating surface. The auxiliary assembly includes a frame body sitting on one side with respect to the operating surface of the portable electronic device. The frame body forms a holder extending outwardly from one sidewall of the frame body.

Abstract: A securing device for securing an electric device having a groove is disclosed. The securing device includes a base and a buckle-hook module. The base covers a portion of the electric device and has a connecting part corresponding to the groove. An operating unit and a buckle-hook unit of the buckle-hook module are rotatably disposed in the connecting part. The operating unit has a first position and a second position. The buckle-hook unit has an insert part. A resetting unit of tile buckle-hook module is disposed between the buckle-hook unit and the connecting part, so that the buckle-hook unit is rotated to and from. When the operating unit is moved from the first position to the second position, the insert part inserts into the groove, for securing the electric device.

Abstract: An audio output apparatus includes: an audio codec outputting an analog audio signal corresponding to a digital audio signal from a system controller; a switch unit having a first end coupled to the audio codec through a capacitor, and a grounded second end; and a switch controller triggered by a trigger signal to output a control signal to a control end of the switch unit such that the switch unit couples the capacitor to ground in response to the control signal. The trigger signal is generated by one of the system controller, the audio codec, and a power circuit supplying electric power to the system controller, the audio codec and the switch controller upon occurrence of a condition associated with pop noise, and is outputted to the switch controller before the pop noise is generated, such that the pop noise is conducted to ground via the switch unit.

Abstract: A charge circuit adapted to be used in an information system for charging a battery mounted in the information system, the information system being electrically coupled to a power source. The charge circuit includes a pulse width modulation controller electrically coupled to the battery for controlling a charge current to be delivered to the battery, and a system current detecting feedback circuit electrically coupled to the power source and to the pulse width modulation controller for outputting a control signal to the pulse width modulation controller in response to the comparison between a current outputted from the power source and a threshold value. The present invention also a charging method for an information system.
