A method and apparatus for initiating communications on a shared channel in a mobile communication system are provided. A user equipment transmits an uplink signal for requesting communications on the shared channel to a Node B, and waits for a delay duration without monitoring a downlink after transmitting the uplink signal. When the delay duration has elapsed, the user equipment monitors the downlink during a valid period and determines whether a downlink signal responding to the uplink signal is received in a transmission time interval within the valid period. When the downlink signal is received in the valid period, the user equipment transmits and receives data on the shared channel.

An electronic apparatus having a load (90) including: a power supply unit (70) supplying a driving voltage to the load (90); an inverter unit (50) switching the driving voltage; and a control voltage supply unit (30) outputting a first control voltage lower than a reference voltage applied to one terminal of the inverter unit, and a second control voltage higher than the reference voltage, thus controlling the inverter unit. Thus, the electronic apparatus and power circuit are capable of improving a control voltage applied to an inverter unit (50) to reduce the switching loss of the inverter unit.

The invention provides a vehicle surroundings monitoring system for synthesizing and displaying images captured by a plurality of cameras (CA1-CA4) to provide images that, near the border (BLA12,BLA23) between partial images, are more accurate and more readily understood by the user than has been the case conventionally. In the synthesized image, a partial image captured by a first camera and a partial image captured by a second camera are adjacent to one another at their border. Near this border, the capturing directions of the first and the second cameras both substantially match the direction of the border. Consequently, images of objects near the border extend along the border, and thus do not disappear on the synthesized image.

Embodiments of the invention provide a method for recording bursts on a disk and a related apparatus. In accordance with an embodiment of the invention, a method for recording bursts on a burst field of a servo sector of a disk comprises generating a first write current corresponding to burst data provided by a write channel circuit, and generating a second write current having a higher frequency than the first write current using a high frequency AC current generator, wherein the high frequency AC current generator is independent from the write channel circuit. The method further comprises selectively applying the first write current to a write head in response to a signal and selectively applying the second write current to the write head in response to the signal.

Provided is a wireless mobile communication system in which a mobile station reports a headroom value indicating the magnitude of currently used transmission power and additionally usable transmission power. An uplink scheduling method of a Base Transceiver Station (BTS) includes normalizing the headroom value according to a pre-set reference transmission format; determining a mean data rate of the mobile station; and determining a priority of the mobile station considering the normalized headroom value and the mean data rate.

A method and system for providing to a user a set of alternative query suggestions is disclosed. The method, system and computer readable medium product in accordance with embodiments of the invention includes generating an index of all words in a corpus of documents available to the application, generating a popularity table for the index having a popularity value for each word in the index based on occurrences of the word in the corpus, comparing each entry in the popularity table to suggestions from a word generator, compiling a lexicon of word generator suggestion words that are found in the popularity table, submitting each word in the search query to the word generator to determine suggestion words, and displaying to the user one or more of the suggestion words from the lexicon that are more popular than the query word.
摘要:
An optical recording/playback apparatus and a method for adjusting playback parameters of the optical recording/playback apparatus are disclosed. The method includes loading an optical disc, determining whether there is data recorded on a data zone of the optical disc, recording test data on an optimal power control (OPC) zone on a playback parameter adjustment area of the optical disc at a reference power when there is no data recorded in the data zone, and adjusting a playback parameter while reading the playback parameter adjustment area, and recording data in the data zone after the adjustment.
