Abstract: A fuel cell electrical power generation system is described herein. The system uses a combustor to increase the pressure and temperature of exhaust gases from a fuel cell stack of the system. The combustor uses hydrogen from a hydrogen supply to provide fuel to the combustor. The increased temperature/pressure of the exhaust gases post combustion are used to rotate a turbine, which in turn rotates a compressor of a turbocharger. The compressor compresses incoming air to increase the power output and/or the efficiency of the system. An ebooster can be used in low load conditions, such as during a startup or during at time in which the electrical loading on the fuel cells is relatively low.

Abstract: Communication apparatus includes a one-way, hardware-actuated data relay, which includes a first hardware interface configured to receive a command from a communications network and a second hardware interface configured to convey the received command to a protected destination when the relay is actuated. A decoder includes a third hardware interface configured to receive a digital signature for the command from the communications network and hardware decoding logic coupled to verify the digital signature and to actuate the relay upon verifying the digital signature, whereby the command is conveyed via the second hardware interface to the protected destination.

Abstract: A method for communication includes receiving in a secure installation via a network from a remote user terminal an input comprising a stream of symbols that has been encrypted using a preselected encryption key. The encrypted stream of symbols is decoded in the secure installation using a decryption key corresponding to the preselected encryption key, to produce a clear stream of symbols. A computer program running on a processor in the secure installation is used in processing the symbols in the clear stream and generating a graphical output in a predefined display format in response to processing the symbols. The graphical output is outputted from the secure installation to the network in an unencrypted format for display on the remote user terminal.

Abstract: Communication apparatus includes at least first and second communication interfaces, configured for digital communication with first and second nodes. At least one processor is coupled between the communication interfaces, and is configured, upon receiving a message from one of the first and second nodes that is directed to the other of the first and second nodes, to carry out the following actions: when the message contains a command, to convey the command to the other of the first and second nodes; when the message contains status information, to convey the status information to the other of the first and second nodes; when the message contains a response to a command, to discard the response; and when the message contains a query, to block the query from reaching the other of the first and second nodes.

Abstract: Described are techniques used in monitoring the performance, security and health of a system used in an industrial application. Agents included in the industrial network report data to an appliance or server. The appliance stores the data and determines when an alarm condition has occurred. Notifications are sent upon detecting an alarm condition. The alarm thresholds may be user defined. A threat thermostat controller determines a threat level used to control the connectivity of a network used in the industrial application.
