A way of reducing undesirable audio signals is provided. A portable device is provided that comprises a sensor to sense an audio signal and a control unit that is communicatively coupled to the sensor. The control unit is provided to receive a first audio signal from a storage unit and to generate a second audio signal based on at least a portion of the sensed audio signal to reduce an undesirable audio signal. The control unit is further provided to combine the first audio signal and the second...

Fungal pathogen is applied to weeds in such a manner that misting or an extended dew period is not necessary to germinate and grow the fungus. In particular, an oil-in-water invert emulsion containing a special additive is applied to the weeds at the same time or immediately after application of the fungal pathogen, wherein the special additive is (a) wax or (b) lecithin in combination with a calcium salt. Lecithin particularly is effective as an emulsifying agent for forming the emulsion, and f...

Isolated and purified peptides and variants thereof, useful to prevent or treat antibody-mediated diseases, or indications caused by an undesirable antibody response to a given antigen, are provided. Also provided are peptides and methods useful to prevent or treat indications associated with the use of viral vectors in gene replacement therapy. Further, a method to inhibit or prevent aberrant immune responses to exogenous, non-infectious antigen is provided.

A system includes proxy logic which detects situations which, unless action is taken, would result in undesirable bus behavior. In one embodiment, the target device of a bus cycle includes proxy logic which determines when the target device is unable to respond correctly to a bus cycle. In this situation, the proxy logic blocks a bus signal from being received by the addressed logic in the target device, thereby preventing the target device from responding at all. In another embodiment, proxy lo...

Tertiary phosphine oxides containing two halomethyl radicals effectively control the growth of undesirable plants, particularly grasses.

A method of and a system for minimizing undesirable brake release in the brake system of a train having a pneumatic brake on each car connected to a brake pipe which is controlled by a brake pipe controller. The method includes determining the status of the brake system throughout the train and determining a minimal brake pipe reduction for the brake pipe controller, using the status of the brake system. The determined minimal brake pipe reduction is displayed by itself or in combination with th...

This invention relates to pyrazolidine compounds, to a method for preparing the same by the reduction of either a pyrazolium or a pyrazolinium salt, and to a method for controlling undesirable plant species therewith.

Isolated and purified peptides and variants thereof, useful to prevent or treat antibody-mediated diseases, or indications caused by an undesirable antibody response to a given antigen, are provided. Also provided are peptides and methods useful to prevent or treat indications associated with the use of viral vectors in gene replacement therapy. Further, a method to inhibit or prevent aberrant immune responses to exogenous, non-infectious antigen is provided.

Whether a selected operating path has an undesirable multiple circuit is determined before operating current is applied by rapidly sampling the voltage level across a selected operating path at a predetermined time after constant current, less than that required for operation, is applied to it. When the path is good, voltage across it at the sampling time is substantial, but when a multiple circuit decreases the inductive impedance normally provided by operating windings, the voltage is decrease...

An apparatus for detecting undesirable combustion characteristics in spark-ignited internal combustion engines. A sensor and a band-pass filter tuned to the frequency of the knock vibration are provided with an output of the band-pass filter being compared with a reference value. The result of the comparison is correlated with undesirable combustion characteristics to be recognized. A rectifier is provided for solid-borne sound signals received by the sensor with the signals passing through the ...
