    Abstract: Systems and methods for determining turbine engine system stability encompass measuring or otherwise determining values of performance parameters, storing a data set of such values in memory, generating a stability indicator, and displaying the stability indicator on an operator interface. The stability indicator is generated by a processor operating in data communication with the computer memory, utilizing customized software algorithms to remove high frequency components, apply an adaptive filter to adjust selected parameters according to a target value of a selected target parameter, and apply a stochastic filters to estimate true values of the selected parameters, based on the remaining variation.

    Abstract: Loudspeaker systems and assemblies are provided in which mid-frequency producing drivers are provided on opposing sides of a high frequency source comprising a linear high-frequency source connected to a waveguide. Crossover circuitry is provided such that the acoustic output from the mid-frequency drivers overlaps with that of the high-frequency source over an intermediate frequency range associated with acoustic interference between the mid-frequency producing drivers. In some embodiments, the mid-frequency producing drivers are recessed behind the output of the waveguide, and optionally angled outwardly from the waveguide, in order decrease the distance therebetween.

    Abstract: A control and distribution system provides electrical power distribution, audio signal distribution, and control signal distribution to one or more audio components, such as a powered loudspeaker element or a signal conditioning device such as a rack-mounted amplifier. Embodiments allow for the monitoring and/or control of parameters and/or components at or near the endpoint of the system. These parameters or components include low-level parameters associated with the external audio devices, as opposed to merely higher level parameters of the system. The control and distribution system may include an uninterrupted power source for providing power in an online or offline mode to selected components of the external audio devices. In some embodiments, online backup power is provided to low-power components without providing power to amplifiers within the external audio devices.
