摘要:
Lamp capsules and systems thereof having a socket, socket holder, and lens holder are provided. Socket holders include a plurality of fins extending radially and outwardly therefrom, and define a cavity into which a lamp is placed. Systems include a lens positioned in the lens holder, and a snoot is connected to the lens holder.

摘要:
Versioned metadata allows multiple versions of metadata for a given object to exist concurrently on a system thereby supporting the parallel execution of operations which would otherwise be mutually exclusive. Metadata updates are permitted while other objects maintain access to another version of the metadata through a versioning infrastructure. The versioning infrastructure allows the creation of new versions of metadata, maintains obsolete versions in the system as long as they are being used by any object, and deletes the obsolete versions once they are no longer in use.
摘要:
A system, method, computer program and article of manufacture for sharing metadata among cursors is provided. A metadata object marked as a versioned object can have multiple versions. Program units can share these versions of object metadata as opposed to copying the non-versioned object metadata into their memory. These program units may contain a pointer to an object's metadata but are otherwise void of the metadata information for the object. A locking protocol for the metadata ensures concurrency control and triggers dependency tracking. A locking protocol for the cursors controls cursor dependency status.

A system includes a gateway that is configured to receive a message from a source for transmission to a destination and multiple communication channels on which to transmit the message to the destination, where the communication channels include different types of communication channels. The system includes a decision engine that is operably coupled to the gateway and the communication channels. The decision engine is configured to select a first communication channel from the communication channels to route the message for transmission to the destination. The decision engine is configured to select a second communication channel from the communication channels to route the message for transmission to the destination in response to a period of time expiring without receiving an acknowledgement from the destination via the first communication channel, where the second communication channel is a different type of communication channel than the first communication channel.
摘要:
A tracking system for reflecting electromagnetic radiation from a source to a target area, having at least one reflecting surface or mirror mounted to a support that fixes the reflecting surface orientation to focus electromagnetic radiation on the target area when the reflecting surface is at a first location at a first predefined time. The system has a path with at least the first location and a second location. The reflecting surface is movable along the path to maintain focus on the target area. The reflecting surface may have an orientation with a fixed declination angle and fixed hour angle. The source may include a moving source such as the Sun.
摘要:
A technique for automatically generating a report comprising normalized differences in performance statistics between two separate periods. In one embodiment of the invention, database performance statistics are collected on a periodic basis over various time periods. In order to accurately compare database system performance between two discrete periods of time, the difference in the performance statistics of each period are normalized prior to comparing the two periods with each other. By normalizing the statistical differences in each period prior to comparing the differences, periods of different lengths of time as well as different levels of database system load may be compared. In one embodiment, a report is automatically generated which lists the performance statistics being evaluated, the difference in the statistic between each period, the value of each statistical difference as normalized by database time, and the difference between the normalized values.
摘要:
A hanger bar assembly includes a first hanger bar member that includes a first rail segment. The first hanger bar member also includes a first channel segment that includes a first channel. The first hanger bar member also includes a first transitional middle segment extending between the first rail segment and the first channel segment. The hanger bar assembly further includes a second hanger bar member that includes a second rail segment. The second rail segment is positioned in the first channel of the first channel segment. The second hanger bar member further includes a second channel segment that includes a second channel. The first rail segment is positioned in the second channel. The second hanger bar member also includes a second transitional middle segment extending between the second rail segment and the second channel segment.
