Abstract: An treatment bath for use in the manufacture of copper plated or metallized semiconductor devices and a method of inhibiting corrosion of copper plated or metallized surfaces and circuitry in the semiconductor devices immersed in an aqueous fluid in a treatment bath comprising adding to the aqueous fluid an effective corrosion inhibiting amount of one or more aromatic triazole corrosion inhibitors; fluorometrically monitoring the concentration of aromatic triazole corrosion inhibitors in the aqueous fluid; and adding additional aromatic triazole corrosion inhibitor to the aqueous fluid to maintain an effective corrosion inhibiting concentration of the aromatic triazole corrosion inhibitor in the aqueous fluid.

Abstract: A method and system are provided to perform a process of dynamically establishing an ad-hoc network including a plurality of work machines, one or more of which move within a work environment, and each of which includes a gateway. The process may be performed by a respective gateway included within a respective one of the work machines and includes determining a first set of work machines that are within direct communication range of the respective work machine based on the respective work machine's current location within the work environment. Further, the process includes determining a second set of work machines that are in direct communication range of one or more of the work machines in the first set.

Abstract: Methods and systems of the present invention are provided for performing proxy control functions in an environment including one or more work machines. Such methods and systems may leverage one or more gateways to serve as a proxy for one or more distinct modules. A gateway, located in a work machine, may be programmed with proxy logic that performs functions associated with certain modules used in a work machine environment. The gateway may monitor a data link and retrieve broadcasted messages. The broadcasted messages may include source and/or destination module address identifiers. The gateway may retrieve messages from the data link based on a determination that the message is destined for a module for which the gateway serves as a proxy. The gateway may route a retrieved message, using a mapping structure, to the appropriate proxy logic that performs functions associated with the destination module.

Abstract: A method and system are provided to perform a process of managing communications in an environment including a work machine having one or more on-board data links connected to one or more on-board modules and a gateway, and one or more off-board data links connected to one or more off-board systems and the gateway. In one embodiment, the process includes receiving a request generated by a first off-board system and transmitted on a first off-board data link and invoking a firewall application that performs a firewall process. The firewall process may include identifying a destination device associated with the request and determining whether the request is authorized based on a profile associated with the first off-board system.

Abstract: Methods and systems are provided for performing protocol conversions in an environment including a work machine having one or more modules coupled to one or more data links. Such methods and systems may leverage one or more gateways to perform tunneling, translating, and bridging operations. Tunneling processes may include receiving a message from a source module in a first protocol, encapsulating the message within transmission units of a second protocol, and transmitting the encapsulated message via the second protocol. Translating processes may include receiving, by the gateway, a message in a first data link protocol including a parameter identifier. The gateway may match the parameter identifier with a parameter identifier included in a translation table and scale associated parameter data using a scale factor corresponding to a second data link protocol. The gateway may then provide the scaled parameter data to a module using the second data link protocol.

Abstract: A room space such as a caravan is provided with a gas fired space heater having an upright casing within which is located a sealed surface combustion unit having a radiant plaque on one side of which gas is burnt. Primary and secondary air for combustion are fed from inlets below the floor of the room to appropriate sides of the plaque. The products of combustion pass upwardly to an upper part of the casing and then are deflected by a baffle sideways and downwardly to an outlet located below the plaque and below the floor of the room.
