摘要:
A method for calibrating a luminance includes measuring a default luminance value of a display device when the display device is set at a default user-configured luminance configuration, calculating a calibration parameter according to a target luminance value and the default luminance value, and storing the calibration parameter in the display device so that the display device exhibits a display luminance value substantially identical to the target luminance value according to the calibration parameter when the display device is set at the default user-configured luminance configuration.

An audio output device including a casing, a first speaker component, a second speaker component and a sound-guiding board, and a video/audio output device using the same are disclosed. The first speaker component is a circular speaker, and is disposed at the casing. The first speaker component faces towards a first direction. The second speaker component is disposed at the casing, and faces towards a second direction which is different from the first direction. The sound-guiding board is a square plate body, located above the first speaker component, and is separated at a predetermined distance from the first speaker component.

A fatigue monitoring apparatus includes a fatigue detecting helmet. The fatigue detecting helmet includes a cap, a first electrode, a second electrode, a fatigue computation device and a power supply. The first electrode is disposed in the cap to contact a head, thereby obtaining a first physiological information. The second electrode is positioned out of the cap to contact the head, thereby obtaining a second physiological information. The fatigue computation device and the power supply are disposed on the cap. The fatigue computation device includes a brainwave computation module and a fatigue judgment module. The brainwave computation module is electrically connected to the first and second electrodes for obtaining a brainwave information based on the first and second physiological information. The fatigue judgment module is electrically connected to the brainwave computation module for obtaining a fatigue information based on the brainwave information.

A light bar includes a wiring substrate, a plurality of light sources, and at least one high efficient heat-dissipating component. The wiring substrate has a first surface and a second surface opposite to the first surface. The second surface is divided into at least one high efficient heat-dissipating section and at least one low efficient heat-dissipating section. The light sources are respectively disposed on the first surface opposite to the high efficient heat-dissipating section and the low efficient heat-dissipating section. The high efficient heat-dissipating component is disposed on the high efficient heat-dissipating section.
摘要:
A method for quickly determining a compression format of an audio-video file by a playback device, where the playback device includes a receiver, a detector, a register, and a processor, is disclosed. The method includes receiving an audio-video file by the receiver; using the detector to detect whether a tag portion exists behind a header of the audio-video file; using the processor to skip the tag portion to set a starting point for loading the audio-video file when the detector detects the tag portion; using the processor to filter out audio-video compression formats not compatible with the tag portion; and using the processor to load a first part to the buffer from the starting point, and determine a compression format of the audio-video file according to the first part.
