  • Publication number: 20070107517
    Abstract: Techniques are described for eliminating the potential continuity errors in fluid connection devices, such as tubes, which can arise in complex systems where many tubes are used. The techniques are based upon the use of ultrasound, light or pressure waves being transmitted along the connecting device using a transmitter and a receiver at either end. Methods are described to cover the external coupling of the transmitter and/or the receiver into the tubing thereby eliminating the need to compromise the connection. The described apparatus can be external to the system or integrated within it. The potential to carry information along the connection device is also disclosed.

  • Patent number: 7219185
    Abstract: A processor having the capability to dispatch multiple parallel operations, including multiple load operations, accesses a cache which is divided into banks. Each bank supports a limited number of simultaneous read and write access operations. A bank prediction field is associated with each memory access operation. Memory access operations are selected for dispatch so that they are predicted to be non-conflicting. Preferably, the processor automatically maintains a bank predict value based on previous bank accesses, and a confirmation value indicating a degree of confidence in the bank prediction. The confirmation value is preferably an up-or-down counter which is incremented with each correct prediction and decremented with each incorrect prediction.

  • Publication number: 20070096943
    Abstract: The present invention extends to configuring detection zones in a traffic monitoring system and to association of detection zones with corresponding traffic signal phases. One or more sensors detect targets within a roadway intersection. The sensors integrate acquired sensor data for the targets into track files. The track files are subsequently used to identify common target paths. A histogram is used to identify common target positions for stationary targets. From the common target positions and the common target paths detection zones are configured. Detection zones are associated with traffic signal phases so that specific detections can be created. Lane boundaries within the roadway intersection are inferred from the common target paths. Permanent stationary target locations are identified from the common target positions.

  • Patent number: 7191432
    Abstract: A high-frequency compound instruction mechanism and method allows performing a common compare immediate function before an add function has completed, thereby reducing the number of cycles to perform the add-compare function. By increasing the speed of performing the add-compare function, a branch mispredict signal may be provided to an instruction pipeline before data registers are affected by the pipelined instructions. The compound instruction mechanism of the preferred embodiments may be implemented within space that is primarily unused within arithmetic logic units, resulting in an implementation that only marginally increases space requirements on an integrated circuit.

  • Publication number: 20060264849
    Abstract: A closed system, spikeless, positive-flow valve device includes a body defining an internal cavity. At the proximal end of the body is an opening which is preferably sufficiently large to receive an ANSI standard tip of a medical implement. The valve includes a plastic, resilient silicon seal which fills the upper cavity and opening with an oval seal cap having a slit. The opening presses the oval seal cap to keep the slit closed in the decompressed state. The slit opens as the nose of the medical implement compresses the seal into the cavity and the seal cap is free from the opening. The housing also includes a fluid space which facilitates fluid flow between the medical implement and a catheter tip.

  • Patent number: 7124318
    Abstract: A multiple parallel pipeline digital processing apparatus has the capability to substitute a second pipeline for a first in the event that a failure is detected in the first pipeline. Preferably, a redundant pipeline is shared by multiple primary pipelines. Preferably, the pipelines are located physically adjacent one another in an array. A pipeline failure causes data to be shifted one position within the array of pipelines, to by-pass the failing pipeline, so that each pipeline has only two sources of data, a primary and an alternate. Preferably, selection logic controlling the selection between a primary and alternate source of pipeline data is integrated with other pipeline operand selection logic.

  • Patent number: 7099999
    Abstract: A computer system includes a main memory, at least one processor, and at least one level of cache. The system maintains reference history data with respect to each addressable page in memory, preferably in a page table. The reference history data is preferably used to determine which cacheable sub-units of the page should be pre-fetched to the cache. The reference history data is preferably an up or down counter which is incremented if the cacheable sub-unit is loaded into cache and is referenced by the processor, and decremented if the sub-unit is loaded into cache and is not referenced before being cast out. The reference counter thus expresses an approximate likelihood, based on recent history, that the sub-unit will be referenced in the near future.

  • Publication number: 20060180695
    Abstract: A seat belt retractor (10) has an actuator (14) for unlocking and locking the seat belt retractor (10). An inertial sensor (18) detects changes in vehicle acceleration and interacts with the actuator (14) to lock and unlock the seat belt retractor (10). The inertial sensor (18) has one inertial sensor mass, each mass (26, 27, 29, 30, 32, 33) has a wide portion (70) and a narrow portion (72). Preferably each inertial sensor mass (26, 27, 29, 30, 32, 33) has a high density body (31) embedded in the wide portion (70) of the elastomeric material (34). The inertial sensor mass (26, 27, 29, 30, 32, 33) has a greater density than the elastomeric material (34). Moreover, the elastomeric material (34) at least partially surrounds an exterior circumferential surface (38) of the inertial sensor mass (26, 27, 29, 30, 32, 33).

  • Patent number: 7089370
    Abstract: A computer system includes a main memory, at least one processor, and at least one level of cache. The system contains at least one segment table having multiple segment entries recording the assignment of segments in an address space. At least some segment table entries include pre-fetch data indicating which portions of a segment should be pre-fetched. Preferably, a segment table entry contains a list of pages for pre-fetching. Preferably, pre-fetching a listed page causes address translation data for the page to be cached in at least one address translation caching structure. Pre-fetching may also cause data contents of the page to be loaded into a cache.

  • Patent number: 7086058
    Abstract: Methods and apparatus are provided for eliminating hot spots on processor chips in a symmetric multiprocessor (SMP) computer system. Some operations, in particular, floating point multiply/add, repetitively utilize portions of a processor chip to the point that the average power of the affected portions exceeds cooling capabilities. The localized temperature of the affected portions can then exceed design limits. The current invention determines when a hot spot occurs and task swaps the task to another processor prior to the localized temperature becoming too hot. Moving of tasks to processors that have data affinity with the processor reporting a hot spot is considered. Further considerations include prioritizing unused processors and those processors that have not recently reported a hot spot.

  • Patent number: 7065694
    Abstract: Methods and apparatus are disclosed that provide for improved addressing of a register file in a computer system. The register file has one or more redundant words. A logical address in an instruction is mapped, during a predecode operation, to a physical address having a larger address space than the logical address. Addresses of nonfaulty words are mapped to the same word in the larger address space as the logical address. Logical addresses that point to faulty words are mapped to a redundant word that is in the larger address space but not in the address space of the logical address. Because all addresses presented to a register file decoder at access time point to nonfaulty words, no delay penalty associated with address compare during the access time is required.
