Abstract: A method for diagnosing an air filter status includes receiving, by a controller, sensor data indicative of a mass air flow rate, an air temperature and an air pressure of an air cleaner assembly including an air filter, determining an air filter life remaining from the sensor data, and receiving data indicative of a vehicle condition. The method also includes determining when a first condition is satisfied and when true, triggering an air filter leakage alert. When the first condition is not satisfied, the controller determines when a second condition is satisfied. When the second condition is satisfied, the controller determines when a third condition is satisfied, and when the third condition is satisfied, triggers an air filter snow intrusion alert. When the second condition is satisfied and the third condition is not satisfied the controller triggers an air filter blockage alert.

Abstract: There is provided an apparatus for plating a portion of a work piece. The apparatus comprises a fixture having a cavity formed therein. The cavity is dimensioned to receive the portion of the work piece. An attaching means is provided for attaching the fixture to the work piece whereby a sealed chamber is formed between the fixture and the work piece. An inlet port in the fixture fluidly communicates with the sealed chamber. An outlet port in the fixture fluidly communicates with the sealed chamber. A circulation system fluidly connects to the inlet port and the outlet port and includes a source of a plating solution. The circulation system is operable to circulate a plating solution through the sealed chamber.
