Abstract: An extension for extending a client application for operation with a server across a network having a gateway or firewall includes an interface for integrating with the client application, and a communication initiator for repeatedly causing the client to initiate a communications session with the server, such that the communications session allows for communication between the client and the server.

Abstract: A static megasonic cleaning system for cleaning multiple objects having an exterior surface includes a cassetteless vessel having an internal cavity for receiving the multiple objects and an array of megasonic transducers mounted on the vessel. Each transducer emits a focused beam of megasonic energy into the cavity and is arranged so that the emitted beams from all of the transducers collectively envelop the entire exterior surface of the objects. The transducers are staggered to avoid internal mounting structure within the vessel and avoid unnecessary dissipation of the megasonic energy.
