Abstract: Methods, systems, and articles of manufacture consistent with certain principles related to the present invention enable a computing system to receive a serialized message including a target object that is associated with at least one member object. The computing system may invoke a deserialize method on a deserializer associated with the target object. In the event the deserialize method cannot completely deserialize the target object, the deserializer may configure a state object returned by the method to monitor a deserialization status associated with the at least one member object. The deserializer may also create an instance builder object that may complete deserialization of the target object in response to receiving a notification reflecting that the at least one member object is deserialized.

In this manner, state management is provided for each entity bean object based on the associated state management type using a corresponding state object. The state management type can be a memory replicated state management type, a disk replicated state management type, a non-replicated state manage type.

Abstract: A static random access memory (SRAM) unit is provided having a read control module, a write control module, and a bypass. The read control module is configured to communicate a read signal defined to read from a first address in the SRAM unit. The write control module is configured to communicate a write signal defined to write to a second address in the SRAM unit. The bypass is disposed to connect the write control module to the read control module. The bypass is further configured to prevent a simultaneous communication of the read signal and the write signal when the first address and the second address are equivalent.

Abstract: The time cost of collecting a region in a Garbage-First garbage collector is adjusted to account for concurrent thread activity. The overhead of a concurrent thread is tracked by dividing elapsed time into relatively short time “windows” and monitoring the system during those windows to determine how long that thread is scheduled to run during those windows. Using measurements of this type for each concurrent thread, the percentage of each elapsed time window dedicated to each concurrent thread is determined. Finally, by summing the percentages of elapsed time dedicated to concurrent thread activity, the cost of collecting a region can be increased by adding the overhead attributable to concurrent activity.

Abstract: Methods, systems, and articles of manufacture consistent with the present invention train a real-time health-monitor for a computer-based system while simultaneously monitoring the health of the system. A plurality of signals that each describe an operating condition of a subject data processing system are monitored in real-time.

The known signal dataset includes a signal value for at least one signal that describes an operating condition of one of a plurality of subject data processing systems. A new signal dataset having an entry for each monitored signal and a corresponding signal value is prepared simultaneously with monitoring the plurality of signals and determining whether there is a problem.

Abstract: An improved method and system for edge adaptive interpolation. The method uses a “9×2” window to detect the edge direction with post-processing to remove any artifacts due to the possible false edge detection, and a hierarchical scheme is employed to reduce the computation required. The method detects if there is edge existing along the current pixel. If there is no edge, then the edge detection output will be 90 degrees (the interpolation will be performed along the vertical direction). If an edge does exist, the method determines whether the edge direction falls within a first or second direction group. Once the edge direction is assigned to a particular group (e.g., 0–90 degrees or 90–180 degrees), the edge direction will be detected among five (5) possible directions. To further improve the edge detection precision, and also to remove the possibility of false edge direction detection, a post-processing technique may be applied to the edge direction signal.

The first and second node each include a protocol server adapted to associate and to send an address to a node requesting an address in the group of nodes, and a memory adapted to store an association address-identifier of a node requesting an address. The protocol server is further capable of requesting the management layer of a node for an indication informing if said node acts as the current monitor node, and attributing, to the current monitor node, the ownership of a list of associations, said list comprising associations of the memory.

Abstract: An apparatus that minimizes phase error and jitter in a phase-locked loop. The apparatus includes a phase/frequency detector, a charge pump, a loop filter, a voltage-controlled oscillator, and a frequency divider, which are coupled together to form a phase-locked loop. The charge pump within the phase-locked loop contains a pull-up network and a pull-down network which are coupled to each other, and a current compensation device. If the pull-up network and the pull-down network are both conducting, the current compensation device adjusts currents flowing through the pull-up network and through the pull-down network such that the currents are substantially equal. This ensures that very little current flows into the loop filter, thereby substantially minimizing a build-up of charge on a capacitor in the loop filter, which can cause phase error and jitter in the phase-locked loop.

Abstract: A display of wavelength elements can be produced from resonant structures that emit light (and other electromagnetic radiation having a dominant frequency higher than that of microwave) when exposed to a beam of charged particles, such as electrons from an electron beam. An exemplary display with three wavelengths per pixel utilizes three resonant structures per pixel. The spacings and lengths of the fingers of the resonant structures control the light emitted from the wavelength elements. Alternatively, multiple resonant structures per wavelength can be used as well.
