  • Patent number: 9003792
    Abstract: In an exemplary embodiment, an internal combustion engine includes an oxidation catalyst configured to receive an exhaust gas flow from the internal combustion engine, a urea injector positioned downstream of the oxidation catalyst to inject a urea flow into the exhaust gas flow and a mixer positioned downstream of the urea injector to mix the exhaust gas flow and the urea flow to form a mixed exhaust gas and urea flow. The engine also includes a particulate filter and catalytic reduction assembly positioned downstream of the mixer to receive the mixed exhaust and urea flow from the mixer to form a treated exhaust gas flow and an exhaust gas recirculation system coupled to the particulate filter to receive a portion of the treated exhaust gas flow and recirculate the portion of the exhaust gas flow to be mixed with a fresh air flow for the internal combustion engine.

  • Publication number: 20150032808
    Abstract: A method, apparatus and computer-readable storage medium distribute a non-live content stream in a network. An initial meta-file is transmitted in response to a request for the content, which identifies a division of the content stream into blocks, and available sources for delivery of the blocks. The initial meta-file can identify a first multicast and a second multicast server, assigning a first and second portion of the blocks for delivery using the first and second multicast source server, respectively. The first and second portions are transmitted using the first and second multicast source servers, respectively. The first and second portions correspond to distinct non-overlapping portions of the non-live content stream. The initial meta-file can also identify a unicast source server, assigning a third portion of the blocks for delivery using the unicast source server, the third potion being transmitted by the unicast source server.

  • Publication number: 20140347186
    Abstract: Embodiments described herein relate to an analyte monitoring device having a user interface with a display and a plurality of actuators. The display is configured to render a plurality of display screens, including a home screen and an alert screen. The home screen is divided into a plurality of simultaneously displayed panels, with a first panel displays a rate of change of continuously monitored analyte levels in interstitial fluid, a second panel simultaneously displays a current analyte level and an analyte trend indicator, and a third panel displays status information of a plurality of components of the device. When an alarm condition is detected, the display renders the alert screen in place of the home screen, the alert screen displaying information corresponding to the detected alarm condition. Furthermore, the actuators are configured to affect further output of the analyte monitoring device corresponding to the detected condition.

  • Patent number: 8424290
    Abstract: A method and control system for controlling an engine during diesel particulate filter regeneration includes a diesel particulate filter (DPF) regeneration request module that generates a DPF regeneration request signal and an idle condition module that generates an idle condition signal when the engine is at an idle condition. A DPF regeneration control module initiates a timer in response to the DPF regeneration request signal and the idle condition signal. The DPF regeneration control module controls the engine oxygen level to a second level less than a first level corresponding to a non-idle speed level, and after a time period, controls the engine to generate oxygen at a third level greater than the second level.

  • Publication number: 20130021478
    Abstract: A method of diagnosing problems experienced with remote control operation of electronic devices includes monitoring background noise signals with a receiver of a signal processing electronic device, such as a set-top box, for use in receiving and rendering multimedia content via a separate display monitor. The electronic device has an internal remote control unit enabling remote control of the signal processing electronic device via wireless signals emitted from a separate remote controller. The background noise signals are analyzed with a signal processing unit residing in the electronic device. From the analysis, the electronic device generates a representation with respect to the background noise signals. The representation may be provided to the end user, technician or call center operator in a readily understandable form for purposes of readily verifying a noise interference problem and providing guidance with respect to mitigation. A device, such as a set-top box, is also disclosed.
