摘要:
The present invention is related to an apparatus and a method for controlling operations of low sound output in an audio system. Embodiments of an apparatus and a method for controlling an operation of an audio woofer in a machine provided with an audio system such as a portable computer can operate using at least one or more information of an audio data type, an audio signal, an audio channel number and a power source. Therefore, it is possible to accurately select and listen to an audio of a high-pass component only by stopping operations of a low-pass component for an audio as reproduced. In addition, embodiments of the present invention can extend a time for using a battery by controlling operations of a woofer, when using the battery power.

An apparatus and method for audio level information recording/management and an audio output level adjustment can record or adjust in accordance with a recorded audio file level information. An audio file can be partitioned into a header information area, an audio data area, and a tag information area where audio file level information can be additionally recorded to indicate an output level of audio data to be reproduced. A digital audio system can check audio level information recorded in an audio file requested to be played and adjust the output level of audio data to be reproduced of the audio file on the basis of the checked audio level information additionally or in combination with a user entered audio volume level. Therefore, the output levels of audio data to be reproduced of respective audio files can be directly or automatically adjusted to a desired level.

An apparatus and method for adjusting the output level of audio data to be reproduced can adjust any one of audio files of different types to a consistent or reference level prior to amplifying at a desired level (e.g., user selected volume). Therefore, digital audio systems and methods according to embodiments of the present invention can reproduce audio files of various types such as an MP3 audio type, MPEG2 audio type and AC3 audio type, and the output level of audio data to be reproduced of each of the audio files can be adjusted to a value corresponding to an audio volume level set by a user, which can prevent or reduce the output levels of the audio data from becoming different because of audio recording levels and recording formats of the audio files set in creation or recording processes thereof.

An apparatus and method for controlling data communication in a wireless local area network (LAN) can check a remaining power level of a host computer battery and determine a data transmission characteristic such as a data transfer speed and/or power save mode period based on the checked battery power, and then adjust the current data transfer speed or power save mode period according to the determined value. For example, a controller of a wireless LAN can transmit information corresponding to the determined transmission characteristic to an access point or another station. Therefore, a station of the wireless LAN card can reduce or prevent power of the battery from being abruptly diminished because of use of the wireless LAN.

Method for controlling a drying course of a laundry dryer including the steps of (a) starting a drying course by using high temperature drying air, and sensing dryness of a drying object periodically, (b) determining a dryness saturation time point at which the dryness sensed thus exceeds a preset reference value Q, (c) determining a load of the drying object according to the drying saturation time point T_sat, and (d) varying a drying algorithm depending on the load of the drying object determined thus, whereby preventing a small amount of laundry from sticking to a drum in a drying course by varying a control algorithm of the drying motor in a case an amount of the drying object is determined to be small accurately with reference to a saturation time point of an electrode sensor.

Controlling heat generated by a computer includes using a thermal sensor configured to monitor temperature of a CPU, a peripheral device controller configured to determine if the monitored temperature of the CPU is higher than a threshold temperature, and an application program configured to designate one or more operating modes for the CPU. The operating modes includes a clock setting and power setting for the CPU based on results from the peripheral device controller. An operating system is configured to implement the clock signal and power settings for the CPU based on results from the application program.

A steam generator for a steam oven. The steam generator includes a water injection unit for supplying water from the outside to the steam generator therethrough; a water tank installed outside a cooking chamber for storing the water supplied through the water injection unit; a flow adjusting unit installed at an outlet of the water tank for adjusting the quantity of the supplied water; a steam pipe connected between the flow adjusting unit and the cooking chamber for changing the water therein into steam and supplying the steam to the inside of the cooking chamber; and a heater installed in the steam pipe for heating the water supplied to the inside of the steam pipe, thereby reducing the overall size of the oven to relatively increase the size of the cooking chamber, and rapidly generating the steam without increasing the capacity of the heater to shorten the overall cooking time.
