摘要:
A method for improving the reliability of host data stored on Fibre Channel attached storage subsystems by performing end-to-end data integrity checks. When a read or write operation is initiated, an initial checksum for data in the read/write operation is generated and associated with the data, wherein the association exists through a plurality of layers of software and attached storage subsystems. The initial checksum is passed with the data in the read/write path. When a layer of software in the read/write path receives the initial checksum and data, the layer performs an integrity check of the data, which includes generating another checksum and comparing it to the initial checksum. If the checksums do not match, the read/write operation fails and the error is logged. If the checksums match, the integrity check is repeated through each layer in the read/write path to enable detecting data corruption at the point of source.
摘要:
A system for coordinating error tracking, level setting and reporting among the various layers/components of a distributed storage system. Each component of the distributed system includes a trigger generation and response (TGR) utility, which generates an error tracking trigger (ETT), comprising: (1) an action that the initiator wants the stack's error tracking mechanisms to take; (2) a message that the initiator wants the stack to immediately post in its logs; and (3) a route/direction that the trigger is to be transmitted through the stack. The ETT is transmitted one layer at a time through the stack, and each intervening layer of the stack is equipped with a utility to examine the ETT and take the appropriate action(s), designated by the trigger. An error log is maintained by each layer of the stack and used to record information about the error and enable user determination of the source, timing and cause of errors.
摘要:
A method and system for remote diagnostic monitoring of a healthcare device, for example, a patient support system. The system includes a communication device configured to transmit sensor data received from a sensor system coupled to the patient support system and configured to generate sensor data relating to diagnostic information of the healthcare device. The communication device can also be configured to receive configuration data for configuring at least one of the healthcare device and the sensor system. The monitoring device is located geographically distant from the healthcare device, is coupled to the communication adapter by a datalink, for example, a telecommunication network, and is configured to receive the sensor data. The monitoring device is configured to determine, based on the received data, whether service or replacement of the healthcare device or a portion thereof is indicated.

摘要:
A power generating system comprising a bluff (non-streamlined) body placed in a fluid stream at ninety degrees to the flow direction creates a von Karman vortex street behind the body. In the process, feedback forces are generated that excite the bluff body into oscillation. The bluff body oscillatory movements are coupled to and energize a power generator. Means are employed for electrically varying the natural frequency characteristics of the bluff body such that, over a relatively wide range of fluid flow velocities, the bluff body oscillates at a resonant frequency of the body for maximum energy transfer from the fluid stream to the bluff body.

A defribrillator comprises first and second electrodes (A, B) for application to a patient, a voltage source (60), and an output circuit for connecting the voltage source across the electrodes upon the occurrence of a control signal (64). The output circuit includes a first current path connecting one side of the voltage source to the first electrode (A) and a second current path connecting the other side of the voltage source to the second electrode (B). Each of the current paths contains at least one solid state switching device USD1 (bo) or IGBT1. The switching device(s) USD1 (bo) in at least one of the current paths has no external control and characteristics similar to a Shockley diode.

The present invention provides systemic nucleic acid sequence delivery without conventional systemic administration aids (SAAs). In certain embodiments, vascular permeability agents (VPAs), such as VEGF, are used in conjunction with nucleic acid viral vectors, such as adeno-associated virus (AAV). The present invention also provides methods of treating disease by co-administration of nucleic cid sequences encoding Igf-1 and dystrophin or dystrophin-like proteins.
摘要:
A mechanism is provided for monitoring I/O activity of each device and the total I/O activity for each adapter. When there is low I/O activity for the tape subsystem, the I/O for the disk subsystems may be spread across all available adapters and paths. When I/O activity for the tape subsystem increases, the I/O activity for the disk subsystems may be reduced on the adapter processing the tape I/O, but will continue across all other adapters. If the tape subsystem begins to report errors due to I/O starvation, the disk I/O activity may be adjusted until the errors stop.
