Abstract: Methods and apparatus are provided for active vehicle cabin occupant detection system. The method includes predicting the presence of a vehicle occupant during operation of a vehicle in response to a door sensor indicative of a door opening, a carbon dioxide level and a pressure sensor in a passenger seat indicative of the vehicle occupant in the passenger seat, detecting the presence of the vehicle occupant using a vehicle cabin motion detector in response to the vehicle being shutdown, confirming the presence of the vehicle occupant using an infrared camera to detect a thermal signature of the vehicle occupant in response to the predicted presence of the vehicle occupant, and transmitting an alert via a wireless transmitter indicative of the presence of the vehicle occupant.

Abstract: Methods and apparatus are provided for active vehicle cabin occupant protection system. The method includes detecting a vehicle cabin temperature using a cabin thermal sensor, engaging a vehicle fan and opening a vehicle outside air ventilation duct in response to the vehicle cabin temperature exceeding a first threshold temperature, and starting a vehicle engine and engaging a vehicle air conditioning system in response to the vehicle cabin temperature exceeding a second threshold temperature wherein the second threshold temperature is greater than the first threshold temperature.

Abstract: An internal combustion engine includes a cylinder block defining a combustion chamber therein, and a cylinder head mated to the cylinder block such that the cylinder head covers the combustion chamber. The internal combustion engine also includes a fuel nozzle configured for injecting a fuel into the combustion chamber and a plasma igniter configured for ejecting a plasma into the combustion chamber to ignite the fuel. The plasma igniter extends through the cylinder head and protrudes into the combustion chamber. The internal combustion engine further includes a dielectric coating disposed on the cylinder head. A vehicle including the internal combustion engine is also disclosed.
