Apparatus and Method for Generating Nitric Oxide in Controlled and Accurate Amounts
A nitric oxide generator generates nitric oxide from a mixture of nitrogen and oxygen such as air treated by a pulsating electrical discharge. The desired concentration of nitric oxide is obtained by controlling at least one of a frequency of the pulsating electrical discharge and duration of each electrical discharge pulse.
Apparatus for applying nitric oxide to a treatment site
A device for generating and delivering Nitric Oxide (NO) to a treatment site includes a main unit, an applicator, a connector hose, and a mobile stand. The main unit provides power and a gas to the applicator via the connector hose. The applicator includes a plasma generator for generating NO in a plasma state. The main unit including a user interface to enable a user to control at least one operational aspect of the device. The applicator includes a pistol grip handle, a trigger for actuating the plasma generator, a hose connection for coupling to the connector hose, and a cowl portion for spacing a tip of the plasma generator at a predetermined distance from a treatment site. Sensors are provided with the applicator for sending feedback and monitoring application site temperature, proximity to the application, applicator motion and the like.

Selective catalytic reduction steady state ammonia slip detection with positive perturbation
Described herein is a method for detecting steady state ammonia slip for a motor vehicle having an internal combustion engine and an emissions control system. The emissions control system includes a selective catalytic reduction (SCR) device, a NOx sensor, and a controller. The controller executes a method for ammonia slip detection that includes determining if the SCR device is at steady state, comparing a NOx measurement from the NOx sensor with a predicted NOx value. If the NOx measurement exceeds the predicted NOx value by a threshold, perturbing a reductant injection, the perturbation having a selected magnitude and a selected duration. The method also includes measuring a NOx value resulting from the perturbation and computing a gradient thereof relative to the measured NOx, and ascertaining if a gradient of the NOx resulting from the perturbation exceeds a threshold and identifying a reductant slip condition if so.
