Each switch of the fabric connected to a storage device used in the snapshot process contains a write interceptor module which cooperates with hardware in the switch to capture any write operations which would occur to the snapshot data area. The write interceptor then holds these particular write operations until the original blocks are transferred to a snapshot or separate area so that the original read data is maintained. Should a read operation occur to the snapshot device and the original data from requested location has been relocated, a snapshot server captures these commands and redirects the read operation to occur from the snapshot area. If, however, the read operation is directed to the original drive, the read is provided from the original data areas, even if the data had been replaced. The snapshot server determines the existence of particular snapshot devices, allocates their storage locations, provides this information to both the service interfaces and the write interceptors and handles read and write operations to the snapshot device.

A virtual network has a plurality of nodes. Each node has the capability to provide a service to another node. Each node maintains a list for storing entries each representing a link to another node; each entry contains the address of the other node and a label identifying a service that that other node may provide. Each node also has a store for storing messages received from other nodes, these messages serving to propose a link and containing the identity of the node originating the message, a label identifying a service that that other node may provide and a label identifying a service that that other node requires. When a node needs a service that it is not itself able to provide, it searches the link list for a link having a label that matches the service needed, and in the event that such a link is found it transmits to the node identified by the link a message requesting the service. If, however, no such link is found, it searches the message store for a message identifying another node where the label identifying a service that that other node may provide matches the service needed and the label identifying a service that that other node requires matches the service that the node needing the service has the capability to provide. In the event that such a message is found it initiates the creation of a corresponding entry in the link list. If no such message is found, the node needing the service generates a message serving to propose a link and containing its own identity, a label identifying a service that it has the capability to provide and a label identifying the service that it needs.

System and methods for recognizing sound and music signals in high noise and distortion
A method for recognizing an audio sample locates an audio file that most closely matches the audio sample from a database indexing a large set of original recordings. Each indexed audio file is represented in the database index by a set of landmark timepoints and associated fingerprints. Landmarks occur at reproducible locations within the file, while fingerprints represent features of the signal at or near the landmark timepoints. To perform recognition, landmarks and fingerprints are computed for the unknown sample and used to retrieve matching fingerprints from the database. For each file containing matching fingerprints, the landmarks are compared with landmarks of the sample at which the same fingerprints were computed. If a large number of corresponding landmarks are linearly related, i.e., if equivalent fingerprints of the sample and retrieved file have the same time evolution, then the file is identified with the sample. The method can be used for any type of sound or music, and is particularly effective for audio signals subject to linear and nonlinear distortion such as background noise, compression artifacts, or transmission dropouts. The sample can be identified in a time proportional to the logarithm of the number of entries in the database; given sufficient computational power, recognition can be performed in nearly real time as the sound is being sampled.

Using nonlinear filtering while resizing an image to preserve sharp image detail
One embodiment of the present invention provides a system that uses nonlinear filtering while resizing an image to preserve sharp detail. The system starts with an original image, which is a digital image comprised of a plurality of pixels. Next, the system resizes the original image.

A lock-out circuit is switchable between active and inactive states and receives the supply voltage at a supply node to generate, in the active state, an output voltage on a output terminal thereof. A protection circuit protects against electrostatic discharge, having at least one first diode coupled between the supply node and the output terminal. A cut-off electronic lock couples, in the inactive state, the supply node to the supply terminal by reverse biasing the at least one first diode to make a voltage of the output terminal float.
Thin-film magnetic head having an antistatic layer preventing a protective coat from being electrostatically charged
Provided is a thin-film magnetic head in which a noise due to the voltage potential difference between the read head element and the protective coat surface is suppressed. The thin-film magnetic head comprises: a read head element, one end surface of the read head element reaching an head end surface on the ABS side; a protective coat formed on the head end surface in such a way to cover at least the one end surface of the read head element; and at least one antistatic means for preventing the protective coat from being electrostatically charged, formed on/above the element formation surface, one end surface of the at least one antistatic means reaching the head end surface, the protective coat covering a portion, not the whole, of the one end surface of the at least one antistatic means on the head end surface.
Magnetic recording medium, recording and reproducing device, magnetic recording medium-magnetizing method, and magnetic recording medium-magnetizing device
A magnetic recording medium enhances the quality of a reproducing signal. The magnetic recording medium has a servo pattern formed in a servo pattern area on at least one surface of a disk-shaped substrate by a concave/convex pattern having convex portions (recording areas) and concave portions (non-recording areas), and a data track pattern formed by the concave/convex pattern in a data recording area on the at least one surface of the disk-shaped substrate. In a state where recording data is not recorded in the data recording area, the convex portions in the servo pattern area are DC-magnetized, and the convex portions in the data recording area are AC-magnetized.
Method and apparatus for adaptive gain balancing of at least one of two rotational sensors in a hard disk drive
A hard disk drive and its circuit board and an integrated circuit are disclosed using two piezoelectric devices each having one terminal used to generate signal. The first signal goes to one input of a differential amplifier. The second signal goes to an amplifier whose gain is controlled to create an amplified second signal for the differential amplifier whose output and the first and second signals create a selected signal received by an A/D converter to create a sampled signal used to create a linear disturbance signal and/or a rotational compensation signal, which in turn are used to control the gain of the amplifier to minimize a PES envelope and/or a harmonic PES envelope either in calibration or normal operation of the hard disk drive.
