Patent number: 8890086Abstract: An ion detection system for detecting ions whose velocity varies during an operating cycle. The ion detection system includes a dynode electron multiplier (e.g., a microchannel plate (MCP)) having a bias voltage input, and a bias voltage source to apply a bias voltage to the bias voltage input of the dynode electron multiplier. With a fixed bias voltage applied to its bias voltage input, the dynode electron multiplier has a gain dependent on the velocity of ions incident thereon. The bias voltage applied by the bias voltage source to the bias voltage input of the dynode electron multiplier varies during the operating cycle to reduce the dependence of the gain of the dynode electron multiplier on the velocity of the ions incident thereon.Type: GrantFiled: June 18, 2013Date of Patent: November 18, 2014Assignee: Agilent Technologies, Inc.Inventors: Noah Goldberg, James L.

Patent number: 8875491Abstract: An exhaust gas aftertreatment system and method are provided. The system comprises a controller, a pump, and a volume quantity dispensing unit. The volume quantity dispensing unit comprises a pressure transducer comprising an electric pressure sensor, at least one fine atomizing nozzle for apportioning the aqueous solution directly into an exhaust gas flow, and at least one means for changing a pressure value. The means changes the pressure value in such a way that a pressure output signal from the pressure transducer to the controller is modified from an actual pressure value sensed by the pressure sensor. A first signal provided by the controller to the pump and a second signal provided by the controller to the volume quantity dispensing unit are adapted based on the output signal from the pressure transducer and a further signal indicative of an operating state of the internal combustion engine.Type: GrantFiled: August 17, 2012Date of Patent: November 4, 2014Assignee: Cummins Ltd.Inventors: Friedrich Zapf, Thorsten Pelz, Heico Stegmann

Patent number: 8874397Abstract: A user obtains a set of modules, inserts them into slots of a chassis, and interconnects the modules to form a modular instrument. A signal path extends through the modules. To support calibration of the signal path, a first of the modules (or the chassis or a calibration module) includes a calibration signal generator. A computer directs the first module to apply the calibration signal from the generator to the signal path, and measures the power (or amplitude) of the output of the signal path. The computer reads a factory-measured value A of the calibration signal amplitude from a memory of the first module (or the chassis or the calibration module). The value A and the measured output power of the signal path are used to determine a gain of the signal path. The system compensates for that gain when the signal path is used to measure live operational signals.Type: GrantFiled: January 14, 2011Date of Patent: October 28, 2014Assignee: National Instruments CorporationInventors: Tamir E.
