摘要:
A PBI compound includes imidazole nitrogens at least a portion of which are substituted with a moiety containing a carbonyl group, the substituted imidazole nitrogens being bonded to carbon of the carbonyl group. At least 85% of the nitrogens may be substituted. The carbonyl-containing moiety may include RCO—, where R is alkoxy or haloalkyl. The PBI compound may exhibit a first temperature marking an onset of weight loss corresponding to reversion of the substituted PBI that is less than a second temperature marking an onset of decomposition of an otherwise identical PBI compound without the substituted moiety. The PBI compound may be included in separatory media. A substituted PBI synthesis method may include providing a parent PBI in a less than 5 wt % solvent solution. Substituting may use more than 5 equivalents in relation to the imidazole nitrogens to be substituted.

A computer system includes a video input device that generates video data representing a field of view in front of the video input device. The computer system further includes a buffer and a video processing module. The buffer is configured to record a video clip of the field of view in front of the video input device. The video processing module is connected to the buffer and the video input device. The video processing module includes a video capture device to encode the video data, and a signal processing module. The signal processing module processes the encoded video data in order to calculate an average value of the video data indicative of motion within the field of view in front of the video input device. The signal processing module generates an alarm if the average value is above a predetermined threshold value.

An adapter for sterilizing a needleless connector that has interior and exterior surfaces. The adapter includes a proximal portion that is coupleable in electromagnetic radiation receiving communication with an electromagnetic radiation source and a cavity portion that is coupleable with the needleless connector and that is shaped to receive at least a portion of the needleless connector. The proximal portion and the cavity portion are made from a translucent material so that electromagnetic radiation from the electromagnetic radiation source can, upon operation, propagate through and be refracted by the translucent material to sterilize both the interior and the exterior surfaces of the needleless connector.

Virtually-integrated wire harness design and automated production systems and methods that achieve completely integrated data management by automatically producing scripts to dynamically propagate production commands and data to various subsystems for handling assembling necessary circuits and wire harness layout boards to produce corresponding batches of wire harnesses while script-based methods control configuring, testing, and using wire harness layout boards, and assembling, testing, reworking, and delivering wire harnesses. As derived from CAD-created specifications, the production system uses a programmable, automated wire C&C center prepares individual wire circuits. While automatic wire indexing, sorting, and delivery systems transfer circuits into, and retrieve circuits from, a transportable programmable, automated, indexed storage system equipped with an array of individual circuit tubes, and a script-controlled assembly system sends visual, aural, and other cues to help an assembler populate and configure a wire harness layout board with connector blocks and turn posts, and guides the assembler in building, testing, reworking, and delivering the corresponding batch of wire harnesses.

A system (10) and methods (800, 900) for routing optical signals are disclosed. The system includes a large core hollow waveguide (30) having a reflective coating (40) covering an interior surface (32) of the hollow waveguide configured to guide a light beam (104). At least one area based beam splitter (50) is integrally formed with the hollow waveguide and has an angled reflective surface (52) with a selectable height (H) relative to the interior surface. The angled reflective surface is oriented to redirect a predetermined amount of the light beam (114) based on the height of the angled reflective surface.

The invention generally relates to monoclonal antibodies that recognize at least one compound from the group consisting of (+) methamphetamine, (+) amphetamine, and (+) 3,4-methylenedioxymethamphetamine ((+) MDMA). Generally speaking, the monoclonal antibodies do not recognize (−) methamphetamine, (−) amphetamine, or (−) MDMA.

A router for use in a network includes a scalable architecture and performs methods for implementing quality of service on a logical unit behind a network port; and for implementing storage virtualization. The architecture includes a managing processor, a supervising processor; and a plurality of routing processors coupled to a fabric. The managing processor has an in-band link to a routing processor. A routing processor receives a frame from the network, determines by parsing the frame, the protocol and logical unit number, and routes the frame to a queue according to a traffic class associated with the logical unit number in routing information prepared for the processors. An arbitration scheme empties the queue in accordance with a deficit round robin technique. If a routing processor detects the frame's destination is a viral entity, and so is part of a virtual transaction, the router conducts a nonvirtual transaction in concert with the virtual transaction. The nonvirtual transaction accomplishes the intent of the virtual transaction but operates on an actual network port, for example, a storage device.

A processor module includes a processor and a voltage regulator both mounted on a carrier. The voltage regulator is mounted with its contacts under compression to ensure good electrical contact with pads on the carrier. Heat sinks mounted respectively on the processor and the voltage regulator are rigidly coupled to each other to provide rigidity to the module and thus maintain the desired compression of the voltage regulator contacts.
