Abstract: An application can executes a plurality of tasks and responds to interrupts. The application can include an event logger that writes data values to an event log stored in an assigned partition of memory in response to a call to the event logger, wherein the call includes an identifier of an event and parameters corresponding to the data values, and the event logger ceases further writing to the event log in response to the identifier of the event matching a predefined stop identifier.

Abstract: The present disclosure addresses a system and method for failure tolerant communications using a transmission control protocol, preferably SCTP. In a preferred embodiment, an association is created between two instances of SCTP, where each instance is an endpoint. While an SCTP association provides for multiple IP addresses providing for multiple paths between the instances, it expressly does not provide for failover of the node occupied by the instance itself. The preferred embodiment provides a duplicate instance of SCTP on a separate node in the cluster which provides a hot back-up to the primary instance. The duplicate instance is maintained by replicating the state information for the association to keep the duplicate instance relatively synchronized with the primary instance.

Abstract: A PSTN service control point including multiple subsystems, a memory storing inbound SS7 messages and a SS7 module which internally routes outbound messages directed to the same point code. On receipt of an inbound SS7 message, a SS7 controller stores the complete message in the memory. The SS7 module routes the message to a first subsystem which processes the message and adds new information to the stored message in memory. If the first subsystem needs to collaborate with a second subsystem, it routes the SS7 message through the SS7 module which checks the outgoing message point code. If the destination point code matches the first subsystem point code, the SS7 module treats the message as an inbound message and routes it internally to the second subsystem.

Abstract: An inflatable dunnage bag is formed by a flat, flexible triangular envelope constructed of heavy kraft paper and a sealed inner plastic liner which is inflatable through a valve. The bag is used for shoring load by standing it upright with its base topmost, horizontally oriented, and positioned adjacent the top of the load and its apex positioned contiguous to the bottom perimeter of the load.

Abstract: A dunnage bag having multiple outer plies of paper and an inner ply of plastic has a baffle means opposite the inflation valve to prevent dry burn constituting either a piece of corrugated paper or a similarly flat member of sufficient included area to baffle substantially all of the air projected through the valve and having an expanded thickness sufficient to separate the confronting surfaces of the plastic ply a discrete distance so that the air stream directed through the valve will be diffused transversely and thereby dissipate any vibratory forces tending to produce a dry burn on the plastic ply.

Abstract: A dunnage bag having multiple outer plies of paper and an inner ply of plastic has an air diffuser extending across the inflation valve outlet and connected to the bag to prevent dry burn from inflation of the bag by high-pressure air. The diffuser constitutes a porous flat member having an expanded thickness and through which an air stream is expanded by deforming the member spherically outwardly, thereby to diffuse the flow of air and prevent any vibratory forces tending to produce a dry burn effect on the plastic ply opposite the valve outlet.
