System for integrating java servlets with asynchronous message
In a traditional application server that uses servlets, when a request is dispatched to a thread the service method of the appropriate servlet is called. When the service method returns the response is sent. This is sub-optimal in the case that an asynchronous event must occur before the response can be sent, because the thread running the servlet must block until the event occurs. The invention provides for asynchronous processing of such requests. In one embodiment, the invention provides an extension to the Servlet API which allows the service method to return (and thus the thread to be freed) before the response is ready to be sent. Then when the asynchronous event later occurs the response may be completed and sent.

System and method for implementing distributed priority inheritance
Priority inheritance is implemented across a distributed system, preferably by use of a mutual exclusion object, referred to as a pseudo-mutex, which provides operations for communicating priority of a task which is held to a different connected processor or node of a network and generating a dummy local command of priority at least equal to that of the held task at the remote processor or node in collaboration with a real-time operating system and middleware. The remote real time operating system then carries out priority inheritance in the normal manner to raise the priority of a blocked task, thus reversing any preemption of that task at the remote processor or node. The increase in priority avoids preemption of lower priority processes and thus increases the execution speed of the executing thread to release the existing lock at an earlier time; allowing a lock to be obtained by the higher priority thread. The middleware serves as an intermediary, communicating messages that include pseudo-mutex arguments or similar communications and requests for enabling priority inheritance across nodes.

The algorithm then optimizes the message transmission time-window by minimizing a peak usage request and an average usage request for each processor. The optimized transmission time-windows allows each processor to be separately scheduled.

Method for mitigating adverse processor loading in a personal computer implementation of a wireless local area network adapter
A personal computer's (PC) microprocessor is used to provide both the physical layer (PHY) and media access control (MAC) processing functions required to implement a wireless local area network (WLAN) adapter. This technique uses the polling mechanism associated with the power save (PS) functionality of WLAN protocol to relieve networking stress on the host processing system. It does this while maintaining networking integrity and packet delivery. The WLAN protocol polling mechanism is used to briefly inhibit the transfer of packets from the WLAN access point (AP) during peak periods of network traffic and/or host processor loading. Because the modulation, demodulation, and MAC functions, typically implemented in dedicated hardware on existing adapters are implemented in software running on the host PC microprocessor, other host system processes and applications can interfere with these time critical functions. Conversely, latency introduced by WLAN specific processing tasks during peak periods of network traffic may cause unacceptable delays to the other processes and applications requiring microprocessor attention. In addition to its primary stated purpose of allowing WLAN mobile stations to save power, this technique will use power save polling as a method for controlling delivery of network packets when the host is heavily loaded or when peak interrupt latencies make reliable packet delivery difficult or impossible.

A synthetic aperture radar acquires an image of one or more objects and identifies them as targets. The objects are located in the proximity of clutter within the image such of trees, or a tree line. The radar acquires a SAR image having pixels descriptive of the clutter and the object(s). Regions having object pixels are identified within the synthetic aperture image using an object identification (algorithm), where the object identification (algorithm) utilizes one or more historically known target characteristics and one or more measured characteristic to obtain an output. Boundaries are identified for the one or more objects within the output using an object isolation, such as, for example, a Watershed transform. Clutter pixels are identified external to the one or more objects. The clutter pixels are suppressed from the synthetic aperture image thereby generating a clutter reduced image containing the one or more objects. The objects are compared with known images of a probable target until a match is found, the match representing the target identification.

Aspects of the invention are directed to service and channel discovery in a digital broadcast network. A pilot synchronization symbol, which has known characteristics, is included as a first symbol of digital broadcast frames. The pilot symbol, which can be decoded without having to resort to trial and error methods, contains parameters for the rest of the signal.

If the fixed known part is not found from the examined signal, then the signal will be considered a non-digital-video-broadcast signal or an empty channel, and the receiver can promptly proceed to a next channel/frequency. In this way, detecting non-digital-video-broadcast and empty channels becomes relatively fast.

In a butterfly network, a number of switches are set to provide two paths that are independent of each other, from a first switch to a second switch, and from the first switch to a third switch respectively. Identification of switches to be set from among all switches in the butterfly network depends on the locations of the first switch, the second switch and the third switch relative to one another. The to-be-set switches are determined by starting with the first switch as a preceding switch, identifying the next switch for a path by simply changing the level number (e.g. incrementing the level number) of a preceding switch in the path, and by changing a bit of the row number of the preceding switch (e.g. by replacing the (α-th bit with a corresponding bit from the destination switch's row number), and repeating such acts with the just-identified switch as a preceding switch.

Optical storage medium, optical read/write apparatus, and optical read/write method
An optical read/write apparatus causes a read/write light beam from illuminating means to strike only one side of an optical storage medium including stacked data storage layers each of which is readable/writeable separately from the other layers. In this case, the optical read/write apparatus operates so that data is read/written from/into a second data storage layer after fully recording a recordable area of a first data storage layer. Thus, light can be shone with uniform intensity across the substantially entire recordable area of the second data storage layer without using a complex read/write system even under such conditions that the transmittance to light of the first data storage layer in the recordable area may vary depending on whether any data is recorded in the recordable area.

The head control method controls a protruding flying height of a head in which an energization amount applied to a heater element in the head to thermally expands the head. The head control method includes a resistance-value measuring step of measuring a resistance value of the storage element, an energization-amount calculating step of calculating an energization amount applied to the heater element such that the resistance value measured in the resistance-value measuring step reaches a reference resistance value, and a heater control step of performing control to apply the energization amount calculated in the energization-amount calculating step to the heater element.
Guided target search for hard disk drive applications
A technique to perform a guided partial response target search for characterizing a read channel of a disk drive. A target adaptation scheme pre-selects a plurality of targets from a pool of potential targets based on certain criteria and the selected targets are sorted in linear gradient orders. When target adaptation is being performed by comparing the equalizer output with an ideal reconstructed signal, a difference value sets a gradient vector that is used to determine which direction to move along the sorted list of targets to select the next target.
