Abstract: A method and system for determining a language of a call handled by an automatic call distributor is disclosed. The method includes the steps of detecting the call, sampling an audio portion of the call, fitting a plurality of templates to the sampled portion of the call, and determining a language of the call based upon a best relative fit between one of the plurality of audio templates and the sampled portion of the call.

Abstract: An apparatus and a method are provided for selectively eliminating weeds in agriculture operations. To provide selective elimination, at least two light (radiation) emitters, powered by an internal power source, are modulated to switch on and off at very high speeds. Each emitter emits radiation of a different emitter wavelength. The on/off modulation of one emitter is phase shifted by approximately 90.degree. with respect to the modulation of the other emitter. The pair of emitters are focused on a particular spot on the ground. The light beams, provided by the emitters, are reflected off a plant or the soil and are intercepted by a photodetector. Because plants have a characteristic spectral reflectance in regions of the electromagnetic spectrum which can be discriminated from the spectral reflectance of the background earth, the relative amplitudes of the reflected radiation at the two emitter wavelengths varies depending on whether the radiation is reflected off a plant or the soil.
