Abstract: A data processing apparatus is provided with packing circuitry 130 arranged to receive said source data elements from said trace data receiver and applies a packing protocol to said source data elements to pack data of source data elements of a source trace stream into a packed trace data stream for supply to trace accepting circuitry in a format comprising acceptance data elements. The acceptance data elements have a bit-length that is not a factor of the source data element bit-length. In some arrangements the source data elements are non byte-sized data elements. In alternative arrangements, the packing circuitry packs a first positive integer number of source data elements into a data chunk comprising a second, different positive integer number of acceptance data elements.

Abstract: Vehicles with open loop hydraulic steering systems may suffer from jerky steering due to the necessity to have safety valves in the open loop system to prevent uncontrolled vehicle movement. Traditional open loop steering arrangements allow steering by controlling fluid quantities flowing from the pump to the drive motors. The disclosed vehicle has an open loop hydraulic drive system including first and second variable displacement motors for driving ground engaging mechanisms at first and second sides of the vehicle, respectively. The system includes a control mechanism configured for steering the vehicle by changing the displacement of one of the first and second motors. This allows the operator to change the drive motor speed range during travel.

Abstract: A gas delivery system includes a gas booster module for delivering natural gas from a utility gas service to power generation equipment installed in or around a building in a manner that meets the minimum volume and pressure requirements of the power generation equipment. The gas delivery system advantageously uses pipe of a relatively small size for delivering gas to the power generation equipment, thereby substantially reducing installation costs and eliminating the need for a welded gas line. The gas delivery system also provides a control system that facilitates close control over the gas flow and ensures compliance with local building codes and safety regulations and requirements.

Abstract: A routing protocol is provided for exchanging messages between an initial sender and an ultimate receiver, potentially via a set of intermediaries. The routing protocol provides an optional reverse message path that enables two-way message exchange patterns. The routing protocol can be expressed as a header entry within a message envelope, is independent of the underlying protocol, and can be generated at the application layer of a protocol stack. The routing protocol may allow each intermediary to process the message and dynamically alter the message path en route to the intended recipient.

Abstract: A sequence of processing transactions operating on a cached data set, which depend on each other because they operate on the same items of data from the data set. The transactions are saved until the master copy of the data becomes available. The transactions are played back against the master copy until one of the played back transactions fails because another transaction which operated on the same items of data but against a separate cached copy and originating from another application, was successfully played back on the master copy at an earlier time. At this point, all subsequent transactions which depended on the failing transaction are rolled back on the cached copy (with appropriate failure reports generated) and activity resumes from there. “Chained” (optimistic) transactions can therefore be applied to cached data and can be allowed to progress by recording their dependencies so they can be undone when required.

Abstract: Motion vectors for encoding a predicted frame relative to a reference frame are determined from a phase correlation of corresponding regions of the predicted frame and reference frame. Peaks in the phase correlation are identified, and the location of the peaks are used as candidate motion vectors. From this limited set of candidate motion vectors, the best motion vectors for predicting blocks within each region can be readily identified.

Abstract: An apparatus and a method to eliminate deadlock in a bi-directionally mirrored data storage system are presented. In some embodiments, a first and a second storage servers have established a mirroring relationship. To prevent deadlock between the storage servers and to reduce write latency, the second storage server may hold data received from the first storage server in a replication queue and send an early confirmation to the first storage server before writing the data to a destination volume if the first storage server is held up due to a lack of confirmation. In another embodiment, when the first storage server writes metadata of a persistent point-in-time image (PPI) to the second storage server, the second storage server may send a confirmation to the first storage server after copying the metadata, but before exporting the PPI at the second storage server.
