Abstract: A headset controller for controlling two incoming radio signals for a headset that includes a left earcup and a right earcup. The controller includes a first radio signal input connection configured for receiving a first radio signal from a first radio, and a second radio signal input connection configured for receiving a second radio signal from a second radio different from the first radio. The controller also includes an electrical sensing and switching mechanism that is operative, when both channels have incoming signals, to send each signal separately to a respective earcup. The electrical sensing and switching mechanism is operative, when only one of the two channels has an incoming signal, to send that one signal to both earcups.

Abstract: A method of estimating a mass flow rate of nitrogen oxides in exhaust gas includes sensing a mass flow rate of a flow of exhaust gas from the engine. A nitrogen oxides base concentration for when the engine is operating at a reference state is defined, and a nitrogen oxides ratio for a current operating state of the internal combustion engine is calculated. The mass flow rate of the flow of exhaust gas, the nitrogen oxides base concentration, and the nitrogen oxides ratio for the current operating state of the engine are multiplied together to define an estimated value of the current mass flow rate of nitrogen oxides in the flow of exhaust gas from the engine. The estimated value of the mass flow rate of nitrogen oxides may be compared to the output from a nitrogen oxides sensor to determine proper functionality of the nitrogen oxides sensor.

Abstract: The disclosed adjustable ladder support mechanism solves the problem of unstable extension ladders with a mobile base that can be moved by one man, the base then expanded in both length and width. With the stable base set up, the ladder can be extended, the angle adjusted, and the operator can safely climb the ladder. Worries of the ladder slipping sideways off the ledge against which it is leaned are eliminated. The adjustable ladder support mechanism has two main sections: the base, which provides stability, and the tower, which raises the ladder above the ground.
