The method includes sampling the acoustic pressure wave generated in the operational system and sampling a previously generated corrective modulation signal, the previously generated corrective modulation signal having parameters. The method further includes performing fast Fourier transform processing on the sampled acoustic pressure wave.

Also, the method includes determining the frequency, phase and magnitude of a dominate pressure wave in the acoustic pressure wave based on the fast Fourier transform processing and the discrete Fourier transform processing.

Abstract: A method and implementing computer system is provided in which specific device identification information is acquired when a faulty condition is detected during an information transfer transaction, and the condition is reported to the device driver of the identified device for corrective action without initiating a system shut-down. In one example, PCI adapter sequence information, including tag number, requester bus number, requester device number and requester function number is captured and used in reporting an error condition in order to identify and isolate the adapter in a recovery operation.

Abstract: An apparatus and method for implementing mulitcast in system area network channel adapters are provided. With the apparatus and method, a multicast packet is received in a channel adapter of an end node. The channel adapter determines which local queue pairs are party of the multicast group identified by a destination local identifier in the multicast data packet. Based on this determination, the channel adapter replicates the data packet and delivers a copy of the data packet to each local queue pair that is part of the multicast group.

Abstract: A method and apparatus is provided in which Pipelined Packet Transfers (PPT) are implemented. The PPT methodology includes a request phase and a response phase. The PPT request phase involves a PPT request master delivering to a PPT request target a source address, a destination address and an information packet for the interrupt being requested. The PPT response phase involves the PPT request target becoming a PPT response master with the PPT response master delivering to a PPT request master a destination address and a data packet which includes the interrupt processing information. Pipelined Packet transfers (PPT) are ordered in accordance with a predetermined processing priority to improve performance and avoid deadlock.

A buffer re-naming methodology is implemented to eliminate internal request/completion transaction information transfers between bridge buffers thereby increasing system performance.

Abstract: An injector pack has a box which houses in separate positions a firing mechanism and a syringe housing. The firing mechanism has safe and cocked conditions and as it is located in the box it is constrained to adopt the safe condition by a sleeve grip being held against rotation while a protruding barrel co-operates with cams to rotate it. The firing mechanism when removed can be screwed by its barrel to the rear end of the syringe housing while that is held by the box, and then the whole injector can be withdrawn for use. The syringe is made operable by rotating the barrel to the cocked condition. Pressing the grip forwards then releases a plunger to act on the syringe. The previous retraction of the plunger can be done using a pillar formation upstanding within the box and over which the barrel can be sleeved.

Abstract: A method and implementing system is provided in which system bridge circuits are enabled to execute, or over-commit to, transaction requests from system devices for information transfers which exceed the bridge circuit's current capacity to receive the requested information on its return from a designated target device such as system memory or another system device. The transaction request is moved along the data path to the designated target device and the requested information is returned, in an example, to the requesting device. By the time the requested information is returned to the requesting bridge circuit, a number of the holding buffers usually have been freed-up and are available to accept and pass the information to the requesting device.
