Abstract: A self-correcting exhaust gas temperature sensor system includes an exhaust gas temperature sensor, a controller and a storage device. The exhaust gas temperature sensor is configured to be disposed in an exhaust manifold of a vehicle. The controller is programmed to determine a reading of the exhaust gas temperature sensor at a predetermined time, determine a comparative temperature value, calculate an offset difference between the comparative temperature value and the reading of the exhaust gas temperature sensor, and based on the offset difference relative of the comparative temperature value, replace an exhaust gas temperature sensor offset value with the offset difference or with a threshold value. The storage device is configured to store the offset difference or the threshold value.

Abstract: An exhaust gas temperature sensor diagnostic system includes an exhaust gas temperature sensor, a controller and a storage device. The controller is programmed to wakeup after a predetermined time after engine shutdown, determine a temperature of the sensor and ambient temperature, calculate a difference in the temperature of the sensor after wakeup to a temperature of the sensor at engine shutdown, determine an estimated temperature of the sensor based on the ambient temperature and the predetermined time, add the difference in the temperature of the sensor at wakeup to the estimated temperature to determine a compensated estimated sensor reading, determine a difference between the compensated estimated sensor reading and a corrected sensor reading, compare the difference between the compensated estimated sensor reading and a corrected sensor reading to a threshold to determine whether the sensor is operating properly. The storage device is configured to store information related to the sensor.

Abstract: A vibration dampening mount assembly includes a housing, resilient material, a sleeve and a restricting structure. The resilient material is fixedly attached to an interior surface of the housing and defines a first chamber and a second chamber. The sleeve is disposed within the housing and is centrally attached to the resilient material. The restricting structure between the first chamber and the second chamber includes a first portion attached to the housing and a second portion attached to the sleeve. In response to movement of the sleeve relative to the housing, the second portion of the restricting structure moves relative to the first portion. The first portion and the second portion of the restricting structure define a fluid passageway therebetween. The cross-sectional area of the fluid passageway changes in response to movement of the second portion relative to the first portion.

Abstract: A method of making a three dimensional electrode having an active material layered between a current collector and a separator includes growing nanotubes at predetermined points on a first sheet of electron directing material, wherein the electron directing material is highly conductive and chemically inert; aligning the nanotubes in a direction perpendicular to the first sheet; functionalizing a distal end of each nanotube; bonding a second sheet of electron directing material to the functionalized distal end of each nanotube; depositing magnetic particles along the second sheet; applying a magnetic field to the magnetic particles to rotate the first sheet, the second sheet and the nanotubes ninety degrees to form an electron directing structure; and attaching the electron directing structure on a surface of the current collector with a polymer binder. The electron directing structure is configured to direct electron flow along a layered direction of the three dimensional electrode.
