Filed: 2002-06-26
Abstract: <P>PROBLEM TO BE SOLVED: To provide a working vehicle having turning performance similar to that of a turning HST to the conditions of fields, with a travel transmission basic drive system having high turning performance.  <P>SOLUTION: The working vehicle comprises a steering lever 88 for changing the direction of a body of the working vehicle to the right or left, right and left axles b having rotating speeds changeable with the lever 88, and transmission means for changing the rotating speeds of the light and left axles b so that a radius of turn can be smaller in proportion to the manipulated variable of the lever 88 to be displaced. The lever 88 to be displaced to an approximately maximum position on the light or left side is changeable into a standard turn mode where the axle b located inside during turn is speed-reducible into a stopped condition, a gentle turn mode where the axle b located inside during turn is speed-reducible into a preset low-speed rotating condition, instead of the stopped condition, and a sudden turn mode where the axle b located inside during turn is speed-reduced into the stopped condition and then speed-increased in a reverse direction.  <P>COPYRIGHT: (C)2004,JPO

Title: Method and system for determining degree of polarization
Inventor: ECKERT JOHN
IPC: G01J4/04
Filed: 2002-06-27
Abstract: PROBLEM TO BE SOLVED: To provide a system and a method for accurately determining a degree of polarization(DOP). SOLUTION: Source light of unknown polarization is input into a polarization controller. The polarization controller transforms the polarization of the source light into a plurality of different polarizations. The transformed source light output by the polarization controller is input to a fixed polarizer, which passes a maximal transmitted intensity of the transformed source light at a given transformation perpendicular to an axis of propagation of the source light. The polarizer passes a minimal transmitted intensity of the transformed source light at a transformation orthogonal to the transformation at which the maximal transmitted intensity is passed. The discriminated transformed source light output by the fixed polarizer is input to a light-wave power meter, which measures the intensity thereof.  The maximal and minimal measured transmitted intensities of the discriminated transformed source light can be used to determine the DOP of the source light. In the alternative, Mueller calculus can be used to determine the degree of polarization when at least, four polarization transformations are performed by the polarization controller and angles by which a half-wave plate and a quarter-wave plate of the polarization controller are rotated are known.
