Detecting and handling affinity breaks in web applications
A system and method are disclosed, according to which, the responsiveness of client/server-based distributed web applications operating in an object-oriented environment may be improved by detecting and handling affinity breaks between a client and server. Affinity exists when a client's requests are all routed to the same server. This is often the case, for example, during secure online transactions. A problem occurs when the preferred server becomes temporarily unavailable, and the client's requests are directed to a different server. When the original server is restored, it must detect the fact that its affinity with the client was disrupted, and any client-specific data in its cache may be invalid. In an exemplary embodiment of the system and method disclosed herein, an “affinity command” is exchanged between the client and the server during each client request. The affinity command contains a user ID associated with the client and a “generation ID”, which is unique for each request. When a request is received from a client, the server examines the generation ID in the accompanying affinity command and compares it to its internally recorded value. If they match, the server knows it has not missed any requests. In this case, the server updates the generation ID and sends the new value back to the client, along with the requested cache entry. If the generation ID received from the client fails to match the recorded value, an affinity break is detected, and the server updates its cache from the database.

Persistent caching directory level support
The present invention provides a novel client side caching (CSC) infrastructure that supports transition states at the directory level to facilitate a seamless operation across connectivity states between client and remote server. More specifically, persistent caching is performed to safeguard the user (e.g., client) and/or the client applications across connectivity interruptions and/or bandwidth changes. This is accomplished in part by caching to a client data store the desirable file(s) together with the appropriate file access parameters. Moreover, the client maintains access to cached files during periods of disconnect. Furthermore, portions of a path can be offline while other portions upstream can remain online. CSC operates on the logical path which cooperates with DFS which operates on the physical path to keep track of files cached, accessed and changes in the directories. In addition, truth on the client is facilitated whether or not a conflict of file copies exists.

Apparatus and method for local oscillator calibration in mixer circuits
An apparatus and method for local oscillator calibration compensates for filter passband variation in a mixer circuit, such as a receiver circuit. The receiver includes at least a mixer circuit and a filter coupled to the output of the mixer. During operation, the mixer mixes an RF input signal with a first local oscillator (LO) signal to frequency translate a selected channel in the RF input signal into the passband of the filter. During a calibration mode, the RF input signal is disabled, and the first LO signal is injected into the filter input by leaking the first LO signal through the mixer circuit. The frequency of the LO signal is then swept over a frequency bandwidth that is sufficiently wide so that the actual passband is detected by measuring the signal amplitude at the output of the bandpass filter, thereby determining any variation in the passband of the filter from the expected passband. Once the actual passband is determined, then the frequency of the first local oscillator signal is adjusted or tuned to compensate for any frequency shift of the actual passband compared to the expected passband. Therefore, the selected channel is up-converted into the center of the actual passband of the bandpass filter and will not fall outside the passband. This enables the passband of the bandpass filter to be narrowed, as compared with conventional receivers that do not utilize this calibration procedure. For example, the bandpass filter can be narrowed to one or two channels wide.

Each of the transmitted signals includes a unique periodically-repeating sequence. A received signal is stored by the receiver for at least two repetitions of the periodically-repeating sequence. FFT operations are performed, and the resulting data frequency samples are pruned responsive to a hypothesized residual frequency, a procedure which significantly reduces the total number of subsequent calculations and therefore significantly reduces processing time. A correlation series is determined from the pruned samples and reference frequency samples corresponding to a hypothesized transmitter. If a match is found in the examination of this series, a code phase offset is determined; if not the process is repeated with another hypothesized residual frequency. Multiple correlation series similarly obtained may also be incoherently combined prior to this examination. The apparatus and method disclosed herein is particularly useful for combined position location and communication systems, especially those that are unsynchronized, such as assisted GPS (“A-GPS”) utilized on GSM and UMTS cellular telephone systems.
Method and system for weight generation in an adaptive array with spread spectrum
The present invention comprises a method and system for weight generation in an adaptive array with spread spectrum signals. Signals received by each antenna are amplified, weighted and summed. Complex weighting is achieved by splitting the signal into inphase and quadrature components, and adjusting the gain of each of these components before combining these weighted components. The output signal after combining of the weighted signals from each antenna is downconverted to baseband, creating inphase and quadrature baseband components. The baseband components are multiplied by the spread spectrum sequence to despread the output signal and reduce the bandwidth of the desired spread spectrum signal to the original desired signal bandwidth. The signals received by each antenna are also downconverted to baseband inphase and quadrature components. Each of these components is multiplied by the spread spectrum sequence to despread the output signal and reduce the bandwidth of the desired spread spectrum signal to the original desired signal bandwidth. The despread/filtered individual antenna signals are multiplied by the despread/filtered output signal to generate antenna weights.

Head suspension with multilayer ground, flexure with multilayer ground, and methods of manufacturing them
A head suspension includes a load beam to apply load onto a head that writes and reads information to and from the hard disk and a flexure attached to the load beam and supporting the head. The flexure has write wires and read wires connected to the head. The flexure includes a substrate made of a conductive thin plate, a base insulating layer made of flexible resin and formed on the substrate, and the wires are arranged on the base insulating film. A ground layer is formed at least partly between the substrate and the base insulating layer. The ground layer only corresponds to the write wires in a width direction of the flexure. The conductivity of the ground layer is higher than that of the substrate that is made of a conductive thin plate.
Suspension with locally stiffened load beam
A loadbeam is locally stiffened by either, 1. the addition of strategically placed extra material to the loadbeam, 2. not removing material during the etching process to form the loadbeam, or 3. special forming, by crimping or bending, at specific sites on the beam. The use of local stiffening, when placed about the loadbeam dimple or between the dimple and flexure attachment points, with or without additional damping, can significantly improve the dynamical response of the loadbeam and eliminate vibrational modes of a slider mounted on the loadbeam during HDI interactions with disk surface asperities during disk drive operation.
Head slider capable of being reliably released from effect of moving recording medium
A medium-opposed surface of a slider body is hemisected into first and second areas by the centerline extending in the longitudinal direction of the slider body. The second area is designed to generate a positive pressure larger than that generated at the first area when a load acting on the slider body in a direction toward a recording medium decreases. The head slider of the type is allowed to enjoy the imbalance of the lift on the slider body. This imbalance can be utilized to intentionally induce increases in the roll angle and the pitch angle of the slider body. The increase in the roll and pitch angles causes disappearance of the lift and the negative pressure generated at the medium-opposed surface. The head slider can reliably be distanced from the moving surface of the recording medium solely with the assistance of the airflow acting on the medium-opposed surface.
Magnetic head slider having aperture to prevent fall forward and magnetic disk drive for using said slider
When the flying height of a magnetic head slider lowers, there arises the problem that the magnetic head slider assumes a forwardly falling attitude and a front edge portion of a leading end of the magnetic head slider comes into contact with a magnetic disk surface, causing damage to the disk surface. To address the problem, one aspect of the invention is directed to a magnetic head slider which includes an air bearing surface, a leading end and a trailing end. Three flying pads are formed on the air bearing surface and a step bearing surface is formed around the first and second flying pads near the leading end and a negative pressure groove for producing a negative pressure is formed in such a manner that the leading side is surrounded by the step bearing surface. The third flying pad is formed near the trailing end and is provided with a magnetic head. A step bearing is formed on the leading side of the third flying pad. Further, the magnetic head slider is formed with an aperture in a front edge portion of the leading end.
Perpendicular magnetic recording medium and magnetic storage apparatus using the same
Embodiments in accordance with the present invention provide a perpendicular recording medium with low noise and high recording density by reducing the effects from noise generated from the vicinity of the interface with the intermediate layer of the recording layer, in a perpendicular recording medium utilizing a granular recording layer containing oxygen or oxide additive in a cobalt-chromium alloy formed on an intermediate layer with a ruthenium or ruthenium alloy layer. A first recording layer and a second recording layer are formed in order on an intermediate layer of ruthenium or ruthenium alloy. The first recording layer and the second recording layer are comprised of cobalt as the main material in a granular structure containing chromium and oxygen. The saturation magnetization of the first recording layer is lower than the saturation magnetization of the second recording layer. When a first recording layer saturation magnetization is set as Ms1(emu per cubic centimeter), a second recording layer saturation magnetization is set as Ms2(emu per cubic centimeter), and the first recording layer film thickness is set to t1 (nm), then (Ms2−Ms1)×t1 will be larger than 0 (memu per square centimeter) and smaller than 0.15 (memu per square centimeter).
Perpendicular magnetic recording write head with a self aligned stitched write shield
A perpendicular magnetic recording (PMR) head with single or double coil layers has a small write shield stitched onto a main write shield. The stitched shield allows the main write pole to produce a vertical write field with sharp vertical gradients that is reduced on both sides of the write pole so that adjacent track erasures are eliminated. From a fabrication point of view, both the main pole and the stitched shield are defined and formed using a single photolithographic process, a trim mask and CMP lapping process so that the main shield can be stitched onto a self-aligned main pole and stitched shield.
Mounting spindle shaft in magnetic disk drive
A magnetic disk drive has a problem in that when a shock in excess of a force used to fasten a spindle shaft to a cover is applied, the spindle shaft becomes inclined. Embodiments of the invention overcome this problem. In one embodiment, a cover is formed with a recessed portion at a location opposite to a spindle shaft. The recessed portion is formed with a projection having an end to be in contact with an inclined portion of a tapped hole of the spindle shaft. Thus, a “plug-like” structure is formed. Preferably, a gap between the cover and the spindle shaft is not present. With this structure, even if the shock is applied from outside, the projection of the cover acts as a stopper to suppress a displacement between the spindle shaft and the cover, thus preventing inclination of the spindle shaft.
