Software robustness through search for robust runtime implementations
Software program robustness is improved by successfully masking memory safety errors in the software program. For instance, at least some memory safety errors in a software program can be masked by using a runtime memory manager that approximates the semantics of an infinite heap memory manager. In one example, an approximation of an infinite heap memory manager is implemented by configuring a parameterized memory manager with parameter values such as padding to be added to each allocation on the heap and the amount of deferment before executing a call to free memory on the heap. Ideal configurations balance expected robustness with costs such as added memory and processing time. Ideal configurations can be identified through systematic search of a coordinate space of selected parameters. Ideal configurations can also be identified by statistically correlating success/failure data collected from execution of deployed instances of the software program to the configuration of the memory managers used therein. |

User nodes are enqueued directly to the queue and can be immediately dequeued on-demand by any thread. Preferably, the enqueueing and dequeueing operations include the use of load-linked/store conditional (LL/SC) synchronization primitives. This solves the ABA problem without requiring the use a unique number, such as a queue-specific number, and contrasts with conventional mechanisms that include the use of compare-and-swap (CAS) synchronization primitives and address the ABA problem through the use of a unique number. In addition, storage ordering fences are preferably inserted to allow the algorithm to run on weakly consistent processors. |

Systems and methods for reading only durably committed data in a system that otherwise permits lazy commit of transactions
A “lazy commit” allows database transactions to be committed faster by not waiting for log records of the transaction to be written to disk. When a system crash occurs during the commit process, transactions may be lost because the log data is not available to recreate the transaction. While lazy commits speed up processing, they also increase the potential for data inconsistency. This invention introduces the concept of “durable reads”—transactions that require isolation from lazy commit transactions and which must be guaranteed to read only durably committed data. When durable read transaction attempts to read data changed by a lazy commit transaction, the system ensures the lazy commit transaction's changes are first made durable. |

A consistent pseudo bid function is applied to determine the pseudo bids for each of the bids, or a variable pseudo bid function is selectively applied to some bids. The pseudo bid increases with increased bid prices and/or increased auction budgets. When a winning bid is identified, the winner's auction budget is debited the price of the item won, and the pseudo bid is recalculated using the remaining auction budget. Bidders submitting higher auction budgets are rewarded by being able to win more items because their auction budgets increase their pseudo bids. Recalculating pseudo bids based on remaining auction budgets allows different bidders to alternately win successive rounds as previous winners'auction budgets are reduced. |

Neural stimulation system providing auto adjustment of stimulus output as a function of sensed pressure changes
A neural stimulation system automatically corrects or adjusts the stimulus magnitude in order to maintain a comfortable and effective stimulation therapy. Auto correction of the stimulus magnitude is linked to the measurement of pressure in the vicinity of the electrode-tissue interface. Because the pressure near the electrode-tissue interface can provide a measure of the electrode contacts' proximity to the neural tissue, and hence quantity of electrical energy delivered to the neural tissue, a change in the measured pressure or pressure morphology indicates that the stimulation energy may need to be adjusted. Hence, changes in pressure provide a feedback mechanism that permit the system to effectively auto correct the stimulus amplitude in order to maintain a desired therapeutic effect. |

The tunnelled data traffic is then forwarded to the access edge node. The access edge node receives the tunnelled data traffic, and identifies the service binding corresponding to the received tunnelled data traffic. The access edge node then proceeds with redirecting the tunnelled data traffic to a second access node in accordance with the identified service binding therein. The redirected tunnelled data traffic is received at a second access node, where it is detunnelled and forwarded to the second user domain. The method also provides an access node and an access edge node for performing the invention. |

Generic routing encapsulation tunnel keepalives
A technique that enables a source endpoint of a tunnel employing encapsulation to determine if a destination endpoint of the tunnel is reachable or unreachable. The technique issues “keepalive” packets that are returned to the source endpoint by a reachable destination endpoint. The source endpoint of the tunnel constructs a keepalive packet containing a return-keepalive packet, encapsulates it and forwards it over the tunnel to the destination endpoint. The destination endpoint, in turn, decapsulates the packet to yield the return-keepalive packet and forwards the return-keepalive packet preferably over the tunnel towards the source endpoint. Upon arrival at the source endpoint, the return-keepalive packet is processed. By receiving the return-keepalive packets the source end-point concludes the destination endpoint is reachable. After a predetermined number of return-keepalive packets have not been received, the source endpoint concludes that the destination endpoint is unreachable. |

The conceptual core of the invention can be seen in providing measures which ensure that after a fault has been detected, for example a short circuit at the output, a current is supplied for a short period, for example 15 ms, which is of such a magnitude that a protective device can be reliably and quickly tripped. The period for this is selected in such a manner that electronic components, connected loads and feedlines are not damaged and destroyed. |

Guide for directing tape media along tape path while applying balanced lateral forces to minimize contact between guide and tape
A tape guide is provided for use in routing a tape media, used in a computer or other application, along a pre-specified path of travel. The tape guide is oriented along a vertical axis and comprises three sections or components joined together to form an integral guide structure. Upper and lower sections both comprise frustoconical sections, the respective dimensions of the two frustoconical sections being equal to one another in a useful embodiment. A tape is wrapped around the guide, whereby the tape is directed along its path of travel. As the tape moves, the upper and lower sections apply downwardly and upwardly directed biasing forces, respectively, to maintain the moving tape in an equilibrium position in order to avoid contact between the edges of the tape and any guide structure. |
