An in-ear earphone with a capacitive sensing function is provided. The earphone includes a case, a speaker, a circuit board, and a capacitive sensing unit. The case has an extension tube and an accommodating portion. An ear tip is sleeved on the extension tube. The accommodating portion accommodates the speaker, the circuit board, and the capacitive sensing unit. A sound emitting surface of the speaker faces the extension tube. The circuit board is electrically connected to the speaker, and a sensing chip is disposed on the circuit board. The capacitive sensing unit includes a sensor and a conducting element. The sensor is electrically connected to the sensing chip through the conducting element. When the extension tube is inserted into an ear canal of a user, the sensor returns a sensing signal to the sensing chip, and the sensing chip sends a control signal to control sound output of the speaker.

A computer screen image displaying method is executed after power-on of a computer and includes: receiving data associated with a detected default display mode of a BIOS of the computer and a display mode stored in a display device coupled to the computer; and determining if the default display mode of the BIOS and the display mode of the display panel match, and if so, causing a video controller of the computer to output image signals according to the display mode of the display panel, and if not, causing the video controller to output image signals corresponding to the default display mode of the BIOS. Thus, screen orientation can be controlled during BIOS POST to spare the user the trouble of changing screen orientation under an operating system environment, thereby enhancing efficiency and saving system resources.

A circuit for eliminating pop sounds at power on and off by a moderate waveform, which includes a switch, a feedback network, an operational amplifier and an output network. When power-on, a first input terminal of the switch is connected to a low voltage, and an output terminal of the output network provides an operating DC bias which is gradually increased. When power-off, the first input terminal of the switch is connected to a reference voltage, and the output terminal of the output network provides an operating DC bias which is gradually reduced.

A backlight module (3) includes a light guide plate (31), a light source (32) and an optical conversion device (33). The light guide plate includes an incident surface (311), an emitting surface (312) adjacent to the incident surface and a bottom surface (313) parallel to the emitting surface. The incident surface maintains an oblique angle relative to the bottom surface. The light source is near the incident surface of the light guide plate for radiating light beams toward the light guide plate. The optical conversion device is disposed between the light source and the light incident surface, which is configured for transforming a polarization state of some of the light beams received from the light source such that the transformed light beams can enter the light guide plate through the incident surface.

A device power is supplied for running a storage device. When a device error occurs, a recovery operation is performed on the storage device. When the recovery operation fails, the device power is reset in a compatibility verification operation and the recovery operation is performed again on the storage device.

An exemplary alignment apparatus (2) includes a light source (50) for emitting light (501), a polarized light generator (51) for receiving the light and generating polarized light (504), a polarized light separator (52) for receiving the polarized light and separating the polarized light into a reflection polarized light beam (521) and a transmission polarized light beam (522) having capability to interfere with each other, a light reflector for changing transmission directions of the reflection and transmission polarized light beams to make the reflection and transmission polarized light beams parallel to each other, and a convergent lens (53) for making the reflection and transmission polarized light beams converge and interferingly irradiate a photosensitive polymer layer (30) to obtain an alignment layer (60). Unlike with conventional alignment apparatuses, because the alignment apparatus is no-rubbing, no-contact alignment apparatuses, debris and electrostatic charge are avoided or even eliminated.
