  • Patent number: 11500158
    Abstract: Arrays of fiber pigtails can be used to project and receive light. Unfortunately, most fiber pigtail arrays are not aligned well enough for coherently combining different optical beams. This imprecision stems in part from misalignment between the optical fiber and the endcap spliced to the end of the optical fiber. The endcap is often polished, curved, or patterned, causing the light emitted by the endcapped fiber to refract or diffract as it exits the endcap. This refraction or diffraction shifts the apparent position of the beam waist from its actual position. Measuring this virtual beam waist position before and after splicing the endcap to the fiber increases the absolute precision with which the fiber is aligned to the endcap. This increase in absolute precision reduces the deviation in virtual beam waist position among endcapped fibers, making it easier to produce arrays of endcapped fibers aligned precisely enough for coherent beam combining.

  • Publication number: 20070052991
    Abstract: A test target is written in a non image zone at set time intervals. The test target is sensed. At least one of frequency, amplitude and phase of banding, which is inherent in a printing device, is determined based on the sensed test target. At least one banding compensation parameter based at least on one of the determined frequency, amplitude and phase of banding is determined. Characteristics of producing an image based on the determined banding compensation parameter are adjusted to compensate the banding inherent in the printing device.

  • Publication number: 20060228133
    Abstract: A shaft mounting and loading arrangement includes a shaft rotatably mounted within a frame of an imaging machine by a pair of spaced mounting bearings. A belt is entrained on the shaft between the bearings. The belt applies a belt load to the shaft along an axially length thereof. Loading is applied to the shaft at locations axially flanking the bearings to counteract deflection of the shaft caused by the belt load applied by the belt.

  • Publication number: 20060051141
    Abstract: A split drives system for a printer in which a single drive motor drives a first belt drive system for the image fusing system and a second and separate belt drive system driving the sheet registration system. This split drives system mechanically isolates the second and separate belt drive system from torque fluctuations in the image fusing system via the first belt drive system driving the image fusing system. Also, the split driving system can isolate torque variations in the driving of the print media fuser from the driving of the print media sheet transport.

  • Publication number: 20060024104
    Abstract: An imaging device for producing multicolor images from image data containing data representing an image of a first color and an image of a second color to be registered relative to the image of the first color onto a substrate by transferring toner of the first and second colors to the substrate is provided. The imaging device comprises a first imager, a second imager, a photoreceptor belt, a plurality of rollers mounted to a frame of the imaging device, an angular position sensor, an image data source and a controller. The plurality of rollers define a process path along which the photoreceptor belt is driven past the first and second imagers in a process direction. The plurality of rollers comprises a drive roller that exhibits an eccentricity for which a formula relating angular position as a function of the phase angle of the drive roller to eccentricity is known. The angular position sensor detects the phase angle of the drive roller.

  • Patent number: 6847853
    Abstract: An automated custom power supply design system uses an expert system containing a set of rules, including manufacturing limitations to limit design choices and ensure feasibility and manufacturability of the design. A design interface collects specifications from a user. A complement of power components for satisfying the electrical specifications is defined and mechanical specifications for each component are provided by the system for use in creating the mechanical design. After the mechanical design is established a thermal analysis is performed and the completed design is returned to a host computer. After an order is received, a computer integrated manufacturing system generates all of the specifications required to manufacture the components for the system and the system.
