In particular embodiments, an integrated search system and method for clustering search results into a plurality of groups based on its contents, each of the groups linked by a representative image, is disclosed. The system includes a clustering engine, an image engine, a database, and a web server. The clustering engine is configured to cluster resources stored in the database into a plurality of groups, each group including resources related to a common topic. The image engine determines a representative image for each of the groups. The database stores information on resources included in each of the groups and a representative image for the group. In one embodiment, the web server is configured to provide a user a plurality of images, each representing a group of resources related to common topic, where as the number of resources included in each group increases, a size of a representative image for the group becomes larger. As such, a user can recognize the level of importance of popularity of topics associated with each group of resources by viewing its representative image.

A wobble signal reproducing device and method. The wobble signal reproducing device may include a computation unit for outputting a push-pull signal by use of a signal picked up by wobbling an optical disc; a wobble band pass filter (BPF) unit for applying band pass filtering to the push-pull signal based on a first control signal, applying low pass filtering to the band pass filtering-applied signal based on a second control signal, and outputting a wobble signal; a wobble phase locked loop (PLL) unit for generating a channel clock signal based on the wobble signal, wherein the first and second control signals correspond to the channel clock signal, the wobble BPF unit applies the band pass filtering at a center frequency varying based on the first control signal, and applies the low pass filtering at a cutoff frequency varying based on the second control signal. Accordingly, the wobble signal reproducing device and method can effectively reproduce a wobble signal in the CLV mode as well as in the CAV mode in which the spindle motor rotates at a constant speed.

摘要:
A folding analog-to-digital converter including: a reference voltage generator, a track-and-hold circuit and a first pre-amplification circuit. The reference voltage generator generates a plurality of reference voltages. The track-and-hold circuit generates a sampling control signal having a voltage level lower than or equal to a level of a power supply voltage by maintaining an initial level of a boost capacitor voltage at a level lower than a level of a power supply voltage, and samples and holds an input voltage signal in response to the generated sampling control signal to generate a sampled signal. The first pre-amplification circuit amplifies each of voltage differences between the sampled signal and each of the plurality of reference voltages.
