A method and an apparatus for determining a time offset are disclosed. The method includes: obtaining, by a device at a head end, a time-domain signal based on a received signal; and then determining a time offset based on values of peak-to-average ratios of a preset quantity of symbols starting from a qsymbol in the time-domain signal, where a peak-to-average ratio of the qsymbol is greater than a preset threshold. A new method for determining a time offset is provided, and takes advantages that the time-domain signal obtained by the device at the head end has stronger capabilities of resisting interference such as frequency offset and phase noise. The method for determining a time offset can be applied both to initial ranging and periodic ranging.

The present disclosure relates to compensating method for cell assembly. According to a deviation value of a key position of a measured array substrate, a compensation value of an exposure parameter of black matrix process of a color film substrate is calculated in real time by using historical measurement data of batches. The compensation value is fed back to a manufacturing apparatus in real time. The manufacturing apparatus corrects the key parameter of the apparatus timely according to the compensation value of the exposure parameter of the black matrix, to manufacture a color film substrate matching with the array substrate.

The present invention provides a method and apparatus for generating index as well as a search method and a search apparatus. Index entry comprises at least a search item identifier corresponding to a search item, one or a plurality of index items generated from one or plural pieces of search information, and an accumulator for the search information. The accumulator is generated by accumulating the search information, or accumulating ciphertext of information containing the search information, or accumulating data mapped from information containing the search information. At the time of searching, the index items and the accumulator are provided to a searcher. The searcher extracts search information from the index items and checks whether the extracted search information is complete by using the accumulator. In one embodiment, the accumulator is incorporated in an encrypted inverted index.
