摘要： A hay-type crop harvester has a chassis supported on the ground on wheels and normally displaceable along the ground in a predetermined travel direction. A crop cutter is mounted ahead of the wheels on the chassis and extends transversely substantially the full width of the chassis so as to cut a swath of crop and pass it backward. A central crop conditioner is provided on the chassis between the wheels thereof and two outer crop conditioners are each provided on a respective side of the chassis to respective sides of the wheels. An auger provided with oppositely directed screwthread formations at each of the conditioners transports the crop laterally so that after being cut in a single wide swath it is subdivided into three portions each of which is fed to a respective conditioner. Thereafter the portions may be laid down in windrows between and outside the wheels of the harvester.

摘要： A row-crop harvester has a frame displaceable in a predetermined travel direction and formed with a plurality of forwardly open throats each provided with a respective conveyor chain each in turn spanned over a respective drive sprocket. Each such drive sprocket is carried on a respective drive shaft having a drive gear that meshes with the drive gears of the conveyor chains to each side. Each drive shaft with its respective sprocket and gear are together mounted in a respective housing bolted to the frame of the harvester and having a mounting flange whose outer periphery corresponds to the pitch circle of the respective drive gear. A main gear meshing with one of the drive gears rotates all of these drive gears simultaneously, and each conveyor chain has a stretch exposed in a respective throat of the machine which is opposite the stretch of the flanking chains for backward advance of cut crop.

摘要： A row-crop harvester has a frame displaceable along the ground and formed with a plurality of forwardly opening throats at each of which is provided an endless conveyor chain spanned over a drive sprocket and an idler sprocket. A fluid cylinder mounted on the frame is provided for each of the idler sprockets so that when this cylinder is pressurized it can urge the respective idler sprocket away from the respective drive sprocket and tension the respective conveyor chain. A pressure-responsive switch is connected to each of the fluid cylinders and to a magnetic clutch between the drive for the chopper and drive sprockets for the harvester. When the pressure drops suddenly in any of the cylinders, as happens when a chain breaks, his pressure-responsive switch will respond and open the clutch to shut down the harvester.

摘要： Embodiments of the present invention exploit redundancy of succeeding FFT spectra and use this redundancy for computing interpolated temporal supporting points. An analysis filter bank converts overlapped sequences of an audio (ex. loudspeaker) signal from a time domain to a frequency domain to obtain a time series of short-time loudspeaker spectra. An interpolator temporally interpolates this time series. The interpolation is fed to an echo canceller, which computes an estimated echo spectrum. A microphone analysis filter bank converts overlapped sequences of an audio microphone signal from the time domain to the frequency domain to obtain a time series of short-time microphone spectra. The estimated echo spectrum is subtracted from the microphone spectrum. Further signal enhancement (filtration) may be applied. A synthesis filter bank converts the filtered microphone spectra to the time domain to generate an echo compensated audio microphone signal. Computational complexity of signal processing systems can, therefore, be reduced.

摘要： The invention provides a method for determining a set of filter coefficients for an acoustic echo compensator in a beamformer arrangement. The acoustic echo compensator compensates for echoes within the beamformed signal. A plurality of sets of filter coefficients for the acoustic echo compensator is provided. Each set of filter coefficients corresponds to one of a predetermined number of steering directions of the beamformer arrangement. The predetermined number of steering directions is equal to or greater than the number of microphones in the microphone array. For a current steering direction, a current set of filter coefficients for the acoustic echo compensator is determined based on the provided sets of filter coefficients.
