Inventor: HOFER JUERGEN
IPC: A01D41/127
Filed: 2004-11-01
Abstract: An automatic steering of an agricultural tractor on a surface of a field to be processed is accomplished by equipping the tractor with a camera for taking a picture of a region of the field, which is in front of the tractor, including the surface that is to be processed, generating a pixel data file from a picture signal of the camera, generating texture information with respect to the texture of the surroundings of the pixels contained in the data file, classifying the pixels of the pixel data file while considering the texture information, in order to generate a binary information as to whether or not a particular pixel is to be associated with the surface that is to be processed, generating a steering signal based on the results of the classification, and repositioning the steering device of the harvesting machine according to the steering signal so that the machine is steered automatically along the surface that is to be processed.

Title: Bromide reduction process in liquid solutions
Inventor: ZIEGENBALG GERALD
IPC: C01D3/06
Filed: 2004-11-23
Abstract: The invention provides a method for reducing bromine levels in brine solutions such as potassium chloride brine solutions. Bromide in solution is converted to hypobromite by the addition of an oxidant such as sodium hypochlorite. Hypobromite is precipitated by the addition of a metal cation such as magnesium under conditions of basic pH.  The process is pH dependent such that the most efficient removal of bromine is achieved at a sodium hydroxide concentration of 90 - 200 mM. The pH optimum is also temperature dependent such that increased temperature lowers the optimal pH for bromide removal. The invention further provides a bromine-reduced potassium chloride product, suitable for uses in industrial applications. By the method of the invention bromine levels in a potassium chloride feed stock can be reduced by 97% or more.

IPC: H03F3/21
Filed: 2004-12-03
Abstract: A pulse width modulator is presented herein and it includes a pulse width driver circuit that receives a time varying ramp signal that is modulated by a time varying analog input signal to produce a pulse width modulated drive signal comprised of turn-on pulses having widths that vary with variations in the magnitude of said input signal. A switch is turned on by each drive pulse for a time duration dependent upon the duration of each drive pulse and provides an output signal therefrom. A negative bias amplifier provides a negative bias signal that has pulsations that are synchronized with said drive pulses but of opposite phase. A combiner combines output signal with the negative bias signal to provide a combined output signal.

Title: Audio coding system using spectral hole filling
Inventor: ROBINSON CHARLES QUITO
IPC: G10L19/02
Filed: 2003-05-30
Abstract: Audio coding processes like quantization can cause spectral components of an encoded audio signal to be set to zero, creating spectral holes in the signal.  These spectral holes can degrade the perceived quality of audio signals that are reproduced by audio coding systems. An improved decoder avoids or reduces the degradation by filling the spectral holes with synthesized spectral components. An improved encoder may also be used to realize further improvements in the decoder.

Title: Determining surface properties of a roadway or runway from a moving vehicle
Inventor: TAYLOR CHARLES LEONARD
IPC: E02F3/00
Filed: 2005-01-27
Abstract: The present invention relates to the measurement of the depth of a contaminant, e.g. snow, found on a roadway or runway from a moving vehicle by measuring the distance between where a beam of light hits the upper surface of the contaminant and where the beam of light should have hit the roadway or runway based on the position of the light source. To eliminate the effects of pitch and roll on the measurements a second light source provides a reference spot, whereby the contaminant depth calculations can be performed independent of the distance between the roadway or runway and the light sources. A video recording device, such as a digital camera, is used to capture images of the spots, whereby the distances can be measured by adding the number of pixels between the spots in the images. The present invention can also be used for determining the surface texture/roughness and the coefficient of friction of the roadway or runway by increasing the sensitivity of the recording device to capture minute changes in relative spot position, and by utilizing complex signal processing to correlate the changes in relative spot position to surface texture/roughness.
