A bone member fastener for closing a craniotomy includes a cap and a base interconnected by a narrow cylindrical collar. The cap has an externally threaded stud that screws into an internally threaded bore of the collar, thereby allowing the cap and base to be brought into clamping engagement against the internal and external faces of a bone plate and surrounding bone. In a particularly disclosed embodiment, the base of the fastener is placed below a craniotomy hole with the collar projecting into the hole, and the stud of the cap is screwed into the bore of the base from above the hole to clamp a bone flap against the surrounding cranium. This device provides a method of quickly and securely replacing a bone cover into a craniotomy. The distance between the cap and base can be selected by how far the threaded stud of the cap is advanced into the internally threaded collar. The fastener is therefore adaptable for use in several regions of the skull having various thicknesses. An insertion tool with a long handle permits safe and convenient placement of the base between the brain and the internal face of the bone plate. Some disclosed embodiments of the fastener have a cap and base that conform to the curved surface of the skull, for example by having an arcuate shape or flexible members that conform to the curvature of the bone plate and surrounding cranial bone as the fastener is tightened.

Various embodiments are disclosed of a failure detection system for a solid-state data storage system that can experience difficulties, such as system failure or loss of data integrity, when it runs out of spare storage locations. Spare storage locations can be used by a solid-state data storage system to replace storage locations that have become defective. In one embodiment, a count is kept of the available spare storage locations in a system, or sub-system, and when the amount of available spare locations drops to a threshold value, an action can be taken to avoid the consequences of an impending failure. In other embodiments, the available spare storage locations are monitored by keeping track of the percentage of initially available spare locations still remaining, by keeping track of the rate of new spare locations being used, or by other techniques. In various embodiments, the early failure detection system responds to detection of a possible impending failure by taking one or more of a variety of actions, including, for example, sending an alert notification, enabling additional storage capacity, copying portions of the data stored in the system to other secure storage locations, shutting the system down, and taking no action.

A fault-tolerant node for synchronous heterogeneous database replication and a method for performing a synchronous heterogenous database replication at such a node are provided. A processor executes a computer program to generate a series of database transactions to be carried out at the fault-tolerant node. The fault-tolerant node comprises at least two relational database management systems, each of which are different relational database management system products, each implementing snapshot isolation between concurrent transactions. Each system comprises a database and a database management component. For each database transaction, operation instructions are provided concurrently to each of the systems to carry out operations on their respective databases and to provide respective responses. The responses generated by the systems either comprise an operation result or an exception. Only one of the systems is configured with a NOWAIT exception function enabled, which returns an exception when it is detected that two or more concurrent transactions are attempting to modify the same data item. The other systems are configured with the NOWAIT exception function disabled. The fault-tolerant node detects that two or more concurrent transactions are attempting to modify the same data item, and ensures that all systems apply the same order of modification of the data item by the concurrent transactions.

In a duplex chat conversational trading system, trader terminals monitor for new incoming messages from the time a trader starts to input a new message to the time it is sent. If an incoming message is detected, sending of the message is inhibited and the trader is alerted to the new incoming message whereupon he can confirm his message, modify it or resend it. Messages are exchanged via a chat server which assigns a unique reference number to each message. Where a message received at the server is sent in reply to an earlier message it carries the reference of the earlier message. The server compares this reference to the most recent reference it has logged and notifies the parties of a crossover if the references are not the same.

The present invention relates to a policy resolution method and system, access network and terminal device for enabling modular network-assisted policy resolution, wherein the policy resolution is divided into separate stages each handling specific types of trigger events and performing specific types of policy actions. The separate stages are processed in a chronological order during a policy resolution round, and trigger events which occur during a policy resolution round are frozen until the start of the next policy resolution round. Thereby, modular policy resolution with reduced delays and oscillations can be achieved. Moreover, policy processing can be divided into a policy decision point functions in the network and a policy enforcement point function in the network or terminal device, so that terminal resources used for policy resolution can be saved.

A method and apparatus for transferring AC electrical power to a load from a first power source to a second power source provides for a time delay in the transfer to avoid problems associated with differences in the phases between the power sources. The phase of the voltage waveform from each power source is sensed continuously, and the phase difference is known at all times, so that it can be used when the transfer is necessary. The method and apparatus monitors the voltage from the first power source, and initiates the transfer from the first power source to the second power source in response to an unacceptable condition from the first power source. The second power source is connected only after waiting for a period of time corresponding to the appropriate time delay. By avoiding instantaneous transfers and providing for a delay in the switching to a secondary power source, the present invention avoids the problems associated with transformer saturation, and the resulting draw of a large amount of current from the power source that can cause upstream circuit breakers to trip open, and uninterruptible power systems and engine generators to malfunction.
