The invention provides methods and devices for stereo encoding and decoding using complex prediction in the frequency domain. In one embodiment, a decoding method, for obtaining an output stereo signal from an input stereo signal encoded by complex prediction coding and comprising first frequency- domain representations of two input channels, comprises the upmixing steps of: (i) computing a second frequency-domain representation of a first input channel; and (ii) computing an output channel on the basis of the first and second frequency-domain representations of the first input channel, the first frequency domain representation of the second input channel and a complex prediction coefficient. The method comprises performing frequency-domain modifications selectively before or after upmixing.

A mobile device responds in real time to media content presented on a media device, such as a television. The mobile device captures temporal fragments of audio-video content on its microphone, camera, or both and generates corresponding audio-video query fingerprints. The query fingerprints are transmitted to a search server located remotely or used with a search function on the mobile device for content search and identification. Audio features are extracted and audio signal global onset detection is used for input audio frame alignment. Additional audio feature signatures are generated from local audio frame onsets, audio frame frequency domain entropy, and maximum change in the spectral coefficients. Video frames are analyzed to find a television screen in the frames, and a detected active television quadrilateral is used to generate video fingerprints to be combined with audio fingerprints for more reliable content identification.

A hand-held portable electronic device housing latch and release system including a permanent magnet, a magnet latch plate, a spring and an electromagnetic coil. The permanent magnet is adapted to be connected to a first housing member of a hand-held portable electronic device and the magnet latch plate is adapted to be connected to a second housing member. A magnetic field of the permanent magnet is adapted to exert a magnetic holding force on the magnet latch plate when the first and second housing members are in a first position relative to each other. The spring is adapted to bias the first and second housing members away from the first position. The electromagnetic coil is adapted to at least partially reduce the magnetic holding force by the permanent magnet on the magnet latch plate.

Provided are a speech restoration system and method for concealing packet losses. The system includes a demultiplexer that demultiplexes an input bit stream and divides the input bit stream into several packets; a packet loss concealing unit that produces and outputs a linear spectrum pair (LSP) coefficient representing the vocal tract of voice and an excitation signal corresponding to a lost frame, when a packet loss occurs; and a speech restoring unit that synthesizes voice using the packets input from the demultiplexer, outputs the result as restored voice, and synthesizes voice corresponding to a lost packet using the LSP coefficient and the excitation signal input from the packet loss concealing unit and outputs the result as restored voice when the lost packet is detected, wherein the packet loss concealing unit repeats linear prediction coefficients (LPCs) of a last-received valid frame, produces a first excitation signal for the lost frame using a time scale modification (TSM) method, when the lost frame is voiceless, and produces a second excitation signal by re-estimating a gain parameter based on the first excitation signal, when the lost frame is voiced.

A flip type mobile telephone is provided with a flip cover attached thereto. The flip type mobile telephone comprises a telephone body provided with a keypad and a hinge shaft provided at an end of the telephone body. A flip cover is hingedly connected to the telephone body through hinge caps inserted onto the hinge shaft. The flip cover covers or exposes the keypad when respectively opened and closed. At least one electromagnet is provided at one side of the telephone body which applies an electromagnetic force toward the flip cover. At least one permanent magnet is provided at a side of the flip cover adjacent to the permanent magnet when the flip cover is closed. The permanent magnet allows opening of the flip cover by applying a magnetic force having a polarity opposite to that of the electromagnet when the electromagnet is energized. Accordingly, the flip cover can be opened by means of the repulsive magnetic force produced between the electromagnet and the permanent magnet when the electromagnet is actuated. The electromagnet can be momentarily energized by pressing the mobile telephone's on/off switch when turning the telephone on for use. Thus, the mobile telephone's keypad is conveniently exposed when the mobile telephone is activated for use.

Disclosed herein is a cooling/heating air conditioner with a humidifying function. The cooling/heating air conditioner comprises a refrigeration cycle mechanism including a compressor, an outdoor heat exchanger, expansion units, indoor heat exchangers, and a 4-way valve, to enable both cooling and heating operations, a condensed water collecting device to receive and store condensed water, which is produced in part of the outdoor heat exchanger and indoor heat exchangers serving as evaporators, a steam generating device to change the condensed water gathered via the condensed water collecting device into humidifying steam, and a humidifying spray device to supply the steam generated in the steam generating device to rooms. The cooling/heating air conditioner has the effect of realizing more pleasant air conditioning environment in a heated room that may be easily dried, and of achieving effective utilization of the condensed water.
