    Abstract: A speech signal is received at an input. At least one electrical value associated with the received speech signal is tracked. A dynamic adjustment of the speech signal is determined. The dynamic adjustment is selected at least in part so as to minimize a distortion and minimize an over-amplification of the speech signal based at least in part upon an analysis of the at least one electrical value. The dynamic adjustment is further selected to obtain a desired output signal characteristic for the speech signal presented at an output. The dynamic adjustment value is applied to the speech signal and the adjusted speech signal is presented at the output. The gain of the signal can also be limited to prevent over-amplification.

    Abstract: A continuous stream of noise is created from a plurality of input signals. A smoothing spectrum estimate is continuously calculated from the continuous stream of noise. Noise is responsively removed from a selected one of the plurality of input signals using the smoothing spectrum estimate. The removal of the noise from the selected input signal is performed substantially synchronously and in time alignment with the creating of the continuous stream of noise and the calculating of the smoothing spectrum estimate.

    Abstract: Residual frequency components of a reference signal are suppressed from an error signal. A magnitude of the frequency domain representation of the reference signal is divided by a magnitude of the frequency domain representation of LMS-filtered representation of the error signal to obtain a frequency domain ratio of the frequency domain representation of the reference signal to the frequency domain representation of the LMS-filtered signal. The frequency domain ratio of the frequency domain representation of the reference signal to the frequency domain representation of the LMS-filtered signal is multiplied by the frequency domain ratio of the frequency domain representation of the reference signal to the frequency domain representation of the LMS-filtered signal, to obtain a frequency domain signal having reduced residual frequency components of the reference signal.

    Abstract: A control system for controlling the release of an accessory from any quick hitch coupler coupling the accessory to a hydraulically operable arm of a machine, operated by a pressurized hydraulic system. The control system can be used with a coupler for coupling an accessory to a dipper arm and a control system for such a coupler, such as a quick hitch coupler for coupling an accessory to a dipper arm of a back actor such as may be used by an earth working apparatus. The quick hitch coupler comprises a body member adapted for coupling to the dipper arm, a fixed engaging means mounted on the body member for engaging a first one of a pair of coupling pins mounted on the accessory, and a moveable engaging means mounted on the body member for engaging a second one of the pair of coupling pins of the accessory.

    Abstract: A container for scaling fish prevents the scattering of loosened scales from the fish during scaling. The present container has an open top with liquid impervious walls and floor. The floor slopes to a drain, which may pass through the floor or through a low point along one wall. The drain includes a guard or screen therein, to prevent passage of fish scales or similarly sized articles therethrough. The container is filled with water with the drain capped, or the container is placed in a sink or basin which is filled with water. A fish may then be placed in the container and scaled, with the viscosity and density of the water precluding scattering of the removed scales. When scaling has been completed, the water is drained from the container, with the scales carried to the drain by the water flow and captured by the guard for ease of removal.
