Abstract: Provided are a method, system and article of manufacture, wherein a first application receives a message from a second application, wherein both the first application and the second application execute on a node of a network that comprises a plurality of nodes. The first application also receives an identifier corresponding to a channel over which at least one other application can communicate with the second application, wherein the channel is a logical connection at an application level. The identifier that corresponds to the channel is stored with an identity of the second application. The stored identifier is accessed to allow the at least one other application to communicate with the second application over the channel.

Abstract: A magnetic head assembly with dual parallelogram supporting structure device and method of making the same has a single or multiple track magnetic stripe read head transducer mounted to a support structure by a dual parallelogram spring structure. This dual spring structure allows the head to move perpendicularly and rotationally to the magnetic stripe while preventing the head from rotating in the y direction, namely, preventing lateral movement. The novel magnetic head assembly is produced using a rapid and accurate assembly without the use of mounting screws in single and multiple track configurations. The unique spring also reduces wear on the magnetic heads which increases the functional life of the unit. The simple construction allows inexpensive manufacture of the magnetic head assembly, yet the durability of available manufacturing materials and the structure of the spring provide the magnetic head assembly with a long useful life, requiring little or no maintenance expense or upkeep.
