| 20080271735 | Artificial airway - One embodiment of the invention includes a pediatric pacifier with a passage. An oropharyngeal airway may be inserted through the passage and into a patient's airway. The pacifier may be resilient and may be softer than the oropharyngeal airway. The pacifier may be removably coupled to the artificial airway. The pacifier may encircle, to varying degrees, various portions of the artificial airway. The pacifier may be sized so that no air may pass between the artificial airway and the patient's airway tissue. The pacifier and artificial airway may have numerous channels such as, for example, a first channel for conducting air and a second channel for aspirating fluids. The pacifier and/or artificial airway may come in sets that include variously sized pacifiers and/or artificial airways. The pacifier may also include a non-resilient plug that prevents the patient from fully closing its mouth and occluding its airway. | 11-06-2008 |

| 20090292439 | Method of controlling cylinder deactivation - A method of controlling a cylinder deactivation system is disclosed. Information from one or more sensors is received by a control unit. The control unit compares the current values of a parameter with one or more prohibited ranges in order to determine if cylinder deactivation should be prohibited. The one or more prohibited ranges are discrete ranges, each with a lower limit and an upper limit. | 11-26-2009 |
| 20100050630 | Turbocharged Engine Using an Air Bypass Valve - A system to cool exhaust gas entering a catalytic converter in a turbocharged engine is disclosed. An air bypass valve is controlled to vent pressurized air to the atmosphere to overrev a turbocharger when exhaust gas exceeds a predetermined temperature. The rotation of the turbocharger increases to maintain a desired boost pressure. When this occurs, the turbocharger absorbs more energy from the exhaust gas to maintain the desired boost pressure. Thus, the exhaust gas entering the catalytic converter is cooled. | 03-04-2010 |
| 20100282202 | Method for Controlling an Intake System - A method and a system for controlling an intake system for an engine is disclosed. The method includes steps for selecting an intake mode according to the current engine speed and the current cylinder mode. The method may be used for controlling an intake system in conjunction with a multi-displacement engine having one or more cylinders that may be deactivated. | 11-11-2010 |
| 20110029222 | METHOD FOR CONTROLLING CYLINDER DEACTIVATION - A method of controlling a cylinder deactivation system is disclosed. Information from one or more sensors is received by a control unit. The control unit compares the current values of a parameter with one or more prohibited ranges in order to determine if cylinder deactivation should be prohibited. The one or more prohibited ranges are discrete ranges, each with a lower limit and an upper limit. | 02-03-2011 |

| 20110172896 | CYLINDER INTAKE AIR AMOUNT CALCULATING APPARATUS FOR INTERNAL COMBUSTION ENGINE - A cylinder intake air amount calculating apparatus for an internal combustion engine is provided. The cylinder intake air amount calculating apparatus calculates a cylinder intake air amount which is an amount of fresh air sucked in a cylinder of the engine using an intake air pipe model equation which is obtained by modeling an intake pipe of the engine. An intake air flow rate which is a flow rate of fresh air passing through the intake pipe of the engine is obtained. The cylinder intake air amount is calculated by applying the intake air flow rate and a preceding value of the cylinder intake air amount to the intake pipe model equation. A predicted intake air flow rate which is a predicted value of the intake air flow rate is calculated. A predicted cylinder intake air amount which is a predicted value of the cylinder intake air amount is calculated by applying the predicted intake air flow rate and the cylinder intake air amount to the intake pipe model equation. | 07-14-2011 |

| 20110295525 | CYLINDER INTAKE AIR AMOUNT CALCULATING APPARATUS FOR INTERNAL COMBUSTION ENGINE - A cylinder intake air amount calculating apparatus for an internal combustion engine for calculating a cylinder intake air amount which is an amount of fresh air sucked into a cylinder of the engine, is provided. An intake air flow rate, which is a flow rate of fresh air passing through an intake air passage of the engine, is obtained, and an intake pressure and an intake air temperature of the engine are detected. A theoretical cylinder intake air amount is calculated based on the intake pressure, the intake air temperature, and a volume of the cylinder. A volumetric efficiency of the engine is calculated by dividing a preceding calculated value of the cylinder intake air amount by the theoretical cylinder intake air amount. The cylinder intake air amount is calculated using the volumetric efficiency, the intake air flow rate, and the preceding calculated value of the cylinder intake air amount. | 12-01-2011 |
