  • Patent number: 7917951
    Abstract: An anti-virus system provider distributes an e-mail identifying content filtering rule seeking to identify e-mail messages suspected of containing an item of malware from a central source (20) to users (2). This distribution may be by an e-mail message itself which is appropriately signed and encrypted. At the user system (2), the received e-mail identifying content filtering rule is extracted from the e-mail message and added to the content filtering rules (18) being applied within that user system. In this way, malware which is distributed by e-mail may be identified by characteristics of its carrier e-mail rather than characteristics of the malware itself which not yet have been properly analyzed or the mechanisms for detecting such characteristics of the malware itself not yet put in place.

  • Patent number: 7880298
    Abstract: A semiconductor device thermal connection used to remove heat from a semiconductor device, such as an integrated circuit, includes a metallic barrier layer on the semiconductor device, and a high thermal conductivity material on the metallic barrier layer that joins the semiconductor device to a thermal heat spreader. The metallic barrier layer may be one or more sputtered layers, and the high thermal conductivity material may be a metallic material, for instance including indium, that is soldered onto the sputtered material. The high thermal conductivity material may form a primary thermal connection in conducting heat away from the semiconductor device. A secondary thermal connection may be made between the heat spreader and a heat sink. The secondary thermal connection may include a compressible solid carbon fiber material. A diaphragm may be used to contain the carbon fiber material, to prevent carbon fibers from coming into contact with the semiconductor device.

  • Publication number: 20110005203
    Abstract: A system includes a sampling module, a correlation determination module, and an injector control module. The sampling module samples first and second signals that indicate an amount of nitrogen oxides (NOx) upstream and downstream from a selective catalytic reduction (SCR) catalyst, respectively. The second signal further indicates an amount of ammonia downstream from the SCR catalyst when ammonia is released from the SCR catalyst. The correlation determination module determines an amount of correlation between the first and second signals, wherein the amount of correlation indicates a probability that ammonia is released from the SCR catalyst. The injector control module controls an amount of reducing agent injected into the exhaust gas upstream from the SCR catalyst based on the amount of correlation.

  • Publication number: 20110005209
    Abstract: A system includes an injector control module and an SCR optimization module. The injector control module controls an amount of ammonia (NH3) stored in a selective catalytic reduction (SCR) catalyst to maintain a first storage level. The SCR optimization module determines whether the first storage level maximizes a conversion efficiency of the SCR catalyst at a first temperature and minimizes a probability of NH3 slip when the temperature of the SCR catalyst transitions from the first temperature to a second temperature. The injector control module controls the amount of NH3 stored in the SCR catalyst to maintain a second storage level when the second storage level maximizes the efficiency of the SCR catalyst relative to the first storage level and minimizes the probability of NH3 slip relative to the first storage level.

  • Publication number: 20110005202
    Abstract: A system includes a filtering module that filters a first signal that indicates an amount of nitrogen oxides (NOx) in exhaust gas upstream from a catalyst, and that filters a second signal that indicates amounts of NOx and ammonia (NH3) in exhaust gas downstream from the catalyst. A slip determination module determines whether NH3 is present in exhaust gas downstream from the catalyst based on a frequency response of the first and second signals.

  • Patent number: 7858060
    Abstract: A dosing control system comprises a selective catalytic reduction (SCR) analysis module and a dosing management module. The SCR analysis module estimates an ammonia (NH3) slip rate downstream of an SCR catalyst, an NH3 conversion rate, an NH3 supply rate, and an NH3 oxidation rate. The SCR analysis module estimates an NH3 rate of change based on the NH3 slip, conversion, supply, and oxidation rates and estimates an NH3 storage change based on the NH3 rate of change. The SCR analysis module estimates NH3 stored by the SCR catalyst based on the NH3 storage change. The dosing management module controls dosing agent injection into an exhaust system upstream of the SCR catalyst based on the NH3 stored by the SCR catalyst.

  • Publication number: 20100306169
    Abstract: An apparatus, method and system to enable dynamic replication of Web servers across a wide area in response to access patterns by Web clients as well as in response to customer requests. The method for dynamically replicating one or more parent nodes on a network in response to a user request by a policy manager. The policy manager transmits the user request to an event module. The event module transmits the user request to a data consistency module, wherein the data consistency module maintains integrity of the data on the parent node. The event system communicates with a resource management module to ensure proper utilization of network resources, and transmits the routing request to a request routing module for appropriately balancing the network load. The request routing module is capable of providing optimal routing based on the network resources.

  • Publication number: 20100024389
    Abstract: A dosing control system comprises a selective catalytic reduction (SCR) analysis module, a dosing management module, an adjustment module, and an error module. The SCR analysis module estimates ammonia (NH3) stored by an SCR catalyst, a maximum NH3 storage capacity of the SCR catalyst, and a nitrogen oxides (NOx) measurement for a NOx sensor downstream of the SCR catalyst. The dosing management module controls dosing agent injection upstream of the SCR catalyst based on the maximum NH3 storage capacity and the NH3 stored. The adjustment module outputs an adjusted estimate of the NOx measurement based on the estimate of the NOx measurement, cross-sensitivity of the NOx sensor, and a delay period for exhaust flow. The error module selectively adjusts at least one of the NH3 stored and the maximum NH3 storage capacity based on a difference between the adjusted estimate and NOx measured by the NOx sensor.
