Abstract:
A lens structure, a light source device, and a light source module are provided. The light source device includes a light emitting device and a lens structure. The light emitting device is capable of emitting a light beam. The lens structure includes a first surface, a second surface opposite to the first surface and four total internal reflection surfaces connected to the second surface. Some of the total internal reflection surfaces connect to the first surface. The first surface has a recess. The light emitting device is disposed at the recess. The second surface is a free-form surface. The light beam is capable of entering the lens structure through the first surface, and leaving the lens structure through the second surface.
Abstract:
An exemplary USB interface device includes a circuit board and a USB socket mounted on the circuit board. The USB socket includes a connecting port, a plurality of electrical pins and fixing pins extending from a side of the USB socket. The circuit board defines first and second inserting hole groups. The USB socket can be selectively inserted into the first or second inserting hole group according to the type of USB socket. When the electrical pins and the fixing pins of the USB socket are inserted into and fixed on the first inserting hole group of the circuit board, the second inserting hole group is standing idle. When the electrical pins and the fixing pins of the USB socket are inserted into and fixed on the second inserting hole group of the circuit board, the first inserting hole group is standing idle.
Abstract:
A flashing apparatus controlled by an audio signal on a motherboard and a method for the same is proposed. The flashing apparatus has at least one cold cathode fluorescent lamp (CCFL), a motherboard and a controller. The CCFL is connected to a high voltage cable and receives a high voltage power to emit light of at least one color. The motherboard executes a sound effect software to send a lighting pulse signal to the controller. The controller is electrically connected to the high voltage power for the CCFL. The controller receives the lighting pulse signal and converts it into the high voltage power to make the CCFL flash.

Abstract:
A computer system includes an input output (I/O) device, an I/O control chip, an audio file processing unit, an audio interface, an audio chip, and a power supply. The I/O control chip is configured for receiving a music playing command from the I/O input device, and outputting an audio control signal according to the music playing command. The audio file processing unit stores audio files, and receives the audio control signal to read a corresponding audio file and output an audio processing signal. The audio interface is configured for connecting to an audio device. The audio chip is configured for receiving and processing the audio file according to the audio processing signal, and outputting an audio signal to the audio interface. The power supply supplies standby power to the I/O control chip, the audio file processing unit, and the audio chip when the computer system is not booted up.
