Abstract: A system and method for disabling adaptation in an adaptive feedforward control system at low speeds. The method includes generating a noise signal representative of undesired noise detected by a noise sensor of a vehicle and generating a noise-cancellation signal via a controller within the vehicle. Residual noise resulting from the combination of the acoustic energy of the noise-cancellation signal and the undesired noise is detected by a reference sensor, which generates an error signal based on the residual noise. The error signal and a speed signal from a speed sensor on the vehicle are transmitted to an adaptive processing module for the generation of a filter update signal. The adaptive processing module selectively permits or prevents the filter update signal to adapt filter coefficients of a filter when the speed signal is within a set of conditions.

Abstract: A method for establishing a power profile for a computing device and then using that profile for future power calculations and cost savings estimates after the implementation of a selected power scheme in the computing device is disclosed. This is accomplished by establishing a power profile on a model computing device and then matching that profile to other machines that are similar in configuration. Each tested machine has a power profile that is recorded and saved in cloud based memory storage. A striated matching methodology is utilized to provide the best profile match for each target machine in the enterprise which allows for accurate power calculations for each machine based upon similar original target machine profiles. Once power calculations are done for target machines based on the established profiles, power schemes can then be deployed across an enterprise computing landscape and power calculations taken again to determine potential power savings.
