    摘要: The present invention provides a method for creating uniform pressure at a nip comprising the acts of providing a stationary inner core, pivotally mounting a plurality of shoes to the stationary inner core, creating a plurality of annular chambers wherein each of the shoes occupies one of the chambers. In addition, the method further provides filling each of the chambers with a magneto-rheological fluid, surrounding the plurality of chambers, shoes, and stationary inner core with a thin, metal, rotatable shell; detecting a deformation in the shell and changing a magnetic field in at least one of the chambers to change a viscosity of the magneto-rheological fluid to correct the deformation.

    摘要: A system and method of controlling laser power output levels includes a laser (9) and a control circuit (27) for energizing the laser. A sensor (11) that measures power output from a back facet of a laser element (17) of the laser provides feedback to the control circuit so as to maintain power output from the laser constant. The back facet of the laser element is covered with a coating that has transmission and reflection characteristics that are relatively insensitive to minor changes in the wavelength of the laser. The coating is preferably a thin metallic layer which provides a constant and adequate reflectivity and low transmittance. With the specific metallic layer on the back facet, the transmittance remains relatively consistent even when there is a change in wavelength. This provides for consistent readings at the sensor.

    摘要: A method of making a panoramic image includes capturing a first image (30) defining a first overlap region (115) capturing a second image (40), and defining a second overlap region (215). Two points (150, 151) in the first overlap region are identified and a first vector (175) overlap region connecting the two points is defined. Two points (250, 251) in the second overlap region which correspond to the two points in the first overlap region are identified and a second vector (275) the two points is defined. If points in the first vector match points in the second vector, determine if the first and second vectors are parallel. If the vectors are not parallel, rotate the second vector image until the second vector is parallel to the first vector.
