  • Publication number: 20190328502
    Abstract: Disclosed are methods and devices for isolating all three of the left subclavian, left common carotid and brachiocephalic arteries from embolic debris that might flow through the aortic arch, via a single access point. A system may include an elongate flexible tubular sheath, having a proximal end and a distal end, and an inner member extending through the sheath and moveable relative to the sheath. A left subclavian element may be supported by the inner member. A filter membrane may be configured to isolate the aorta from the brachiocephalic, left common carotid and left subclavian arteries when the left subclavian element is expanded within the left subclavian artery and the sheath is retracted to expose the membrane. The left subclavian element may include a self expandable frame, which may carry a left subclavian filter.

  • Publication number: 20190284492
    Abstract: Fuels, hydraulic fluids and lubricants made of or comprising a portion of renewable hydrocarbon raw materials, as well as biodegradable fuels, hydraulic fluids and lubricants are known to support microbial growth. Highly toxicorganic biocides have been added to reduce microbial growth. The use of such biocides can now be avoided, by instead using a stable solution of boric acid in a solvent, the boric acid being completely dissolved or at least free from any particles larger than 100 nm in size, and adding this solution to the fuel, hydraulic fluid or lubricant to give a final concentration of boron in the range of 1-100 ppm, preferably 1-50 ppm in the product. While preventing microbial growth, the addition of boron also reduces corrosion, in particular microbiologically induced corrosion (MIC).

  • Patent number: 8112560
    Abstract: A direct memory access controller for controlling data transfer between a plurality of data sources and a plurality of data destinations is disclosed. The plurality of data sources and data destinations communicate with the direct memory access controller via a plurality of channels, the direct memory access controller further communicates with a memory and a processor. The memory stores two sets of control data for each of the plurality of channels and for the processor. The direct memory access controller is responsive to a data transfer request received from one of said plurality of channels or from said processor to access one set of said corresponding control data stored in said memory, said direct memory access performing at least a portion of said data transfer requested in dependence upon said accessed control data.

  • Patent number: 7805557
    Abstract: An interrupt controller and method are provided for handling interrupt requests generated by a plurality of interrupt sources. The interrupt controller comprises pend logic for receiving interrupt requests generated by the plurality of interrupt sources, and for each interrupt request, determining whether to accept that interrupt request for handling by the interrupt controller. Interrupt handling logic then selects an interrupt request from amongst those interrupt requests accepted by the pend logic, and generates an indication of the interrupt routine to be executed by a processor to process that interrupt request. The pend logic is arranged, for each of the interrupt sources, to detect a transition of the associated interrupt request from an unset state to a set state, and to accept the interrupt request upon such detection.

  • Patent number: 7607133
    Abstract: A data processing system 2 supporting interrupt handling is provided with an interrupt controller 24. The interrupt controller is responsive to save state data when interrupt processing is commenced by pre-emption of existing processing, whether that be background processing or another interrupt. If a further interrupt is required to be executed immediately after the interrupt which triggered the pre-emption, then the speed with which interrupt processing can be started is advantageously increased if that subsequent interrupt processing is performed without restoring and then resaving the original state data. The interrupts in this arrangement can be considered to be chained together without intervening save and restore operations.

  • Patent number: 7444546
    Abstract: An integrated circuit having a plurality of functional circuits interconnected via a functional bus is provided with a diagnostic bus-master circuit which uses bus transactions on the functional bus to perform diagnostic operations. These diagnostic operations can be performed in real time during normal speed operation of the integrated circuit to produce more accurate diagnostic results. The diagnostic bus-master circuit is particularly useful for reading data values from memory or writing data values to memory as part of diagnostic operations.

  • Patent number: 7278073
    Abstract: An integrated circuit is provided with a diagnostic data capture and output system in the form of a diagnostic data capture circuit which captures a data word and a context word from a bus. The bus may be the functional bus connecting functional circuits within the integrated circuit or a dedicated bus linking one or more functional circuits directly to the diagnostic data capture circuit. The diagnostic data captured is buffered within a first-in-first-out buffer and then serialised for output. The diagnostic data fields also include a time value indicative of the time at which the diagnostic data field concerned was captured and whether any diagnostic data fields have failed to be captured.

  • Patent number: 7206884
    Abstract: A data processing system 2 having a nested interrupt controller 24 supports nested active interrupts. The priority levels associated with different interrupts are alterable (possibly programmable) whilst the system is running. In order to prevent problems associated with priority inversions within nested interrupts, the nested interrupt controller when considering whether a pending interrupt should pre-empt existing active interrupts, compares the priority of the pending interrupt with the highest priority of any of the currently active interrupts that are nested together.

  • Patent number: 7197680
    Abstract: An integrated circuit including diagnostic circuitry having serial scan chains or debug bus access circuits for establishing communication using an interface circuit coupled with a bi-directional serial link to an external diagnostic device. The bi-directional serial link carries both data and control signals. The serial protocol provides for a pacing signal for indicating to the external diagnostic device when it is ready to receive more data and/or when it has completed a particular diagnostic operation. This provides a self-pacing ability. A training signal generated by the external diagnostic device is detected by the interface circuit on initialization and used to derive sampling point timings.

  • Patent number: 7152186
    Abstract: A data processing apparatus controls cross-triggering of diagnostic processes on a plurality of processing devices. The data processing apparatus comprises a routing module having a plurality of broadcast channels, one or more of the broadcast channels being operable to indicate the occurrence of a diagnostic event on one or more of the plurality of processing devices. The data processing apparatus also comprises an mapping module associated with a corresponding processing device. The interface module programmably asserts diagnostic event signals from the associated processing device to one or more of the plurality of broadcast channels and programmably retrieves diagnostic events signals from processing devices other than the associated processing device from one or more of the plurality of broadcast channels. The retrieved diagnostic event data is used to facilitate triggering of a diagnostic process on the associated processing device in dependence upon said retrieved diagnostic event data.

  • Patent number: 7124261
    Abstract: A data processing system 2 has a base data address region 24 and a bit-band data address region 28. Memory accesses to the bit-band data address region 28 are converted into memory accesses to the base data address region 24. In the process of this conversion specific bits within the base data address region 24 are picked out for access whether that be via a read-modify-write operation or a masked read operation as appropriate. In this way, bit access is provided to data values within the base data address region 24 by addressing specific address locations within the bit-band data address region 28.
