Abstract: A fluid compressor includes a housing; a compression chamber within the housing; a motor; a shaft that is rotated by the motor; and a piston assembly including at least two pistons directly connected to each other without any connecting rods. The piston assembly performs a reciprocating motion when acted on by the shaft such that the at least two pistons move within the compression chamber to compress a fluid.

Abstract: Presented herein are systems and methods to automatically and periodically retrieve clinical trial data from an EDC source, process the data to transform it from its initial representation as retrieved from the EDC source into table-based format, and store the resultant transformed data in an intermediate data storage layer for access by stakeholders. Accordingly, instead of accessing source data, such as EDC ODM-XML data directly from an EDC source, a stakeholder may retrieve clinical trial data from the transformed data stored in the data storage layer. The systems and methods provide transformed data that better serves the needs of stakeholders during a clinical trial.

Abstract: An apparatus and method in a computer system allows a software application to specify an intended stride access when writing data elements into a memory. A memory control in the computer system writes data in a manner that provides improved access performance when accesses to the data elements are performed using the intended stride. The memory system uses a hashing mechanism that uses the intended stride to store the data elements in such a way that accessing the data elements at the intended stride will ensure that consecutive accesses are not to the same group or bank of memory. Sequential accesses of the data elements also are ensured not to be directed to the same group or bank of memory. The memory can be divided into memory portions; different memory portions of the computer storage can have different intended strides.

Abstract: Methods and apparatus that may be utilized to improve the scalability of multi-processor systems are provided. Data packets constructed in accordance with a defined coherence protocol may be encapsulated in standard I/O packets. As a result, the same interconnect fabric may be used to route coherent data traffic and I/O data traffic.

Abstract: A unified tag subsystem for a multilevel cache memory system. The unified tag subsystem receives a cache line address including a tag index portion, a high order part and an optional cache line extension field. The tag index portion indexes a tag memory which has way-specific address tags, and lower level flags. A comparator compares the high order part with each way-specific address tag to detect a match. Lower level hit logic determines a hit when comparator detects a match and the lower level flag indicates a valid lower level cache entry; and an upper level hit logic determines a higher level cache hit when the comparator detects a match and the upper level valid is set. In particular embodiments, lower level flag indicates a way of storage where associated data may be found in lower level cache data memory.

Abstract: A load bar (10) comprises a hollow main body (11) having a first and a second open end (21, 22). A first arm (12) is received through the first open end (21) of the main body (11), and is laterally movable therein. A second arm (13) is received through the second open end (22) of the main body and is also laterally movable therein. The positions of the first arm (12) and the second arm (13) with respect to the main body (11) and with respect to each other are releasably securable and adjustable. Also, a bulkhead is provided comprising a load bar (10) as above, and further comprising a header wall (80).
