  • Patent number: 7206008
    Abstract: A method for improving color-to-color registration in a printing device. The method includes printing a plurality of multi-color images, measuring the relative locations of a first portion of each multi-color image having a first color of each image and a second portion of each multi-color image having a second color of each image, for each image, comparing at least one difference between the first portion's location and the second portion's location with at least one desired difference between the first portion's location and the second portion's location to generate a list of positional errors, using a least square regression analysis of the list of positional errors to determine shift amounts required for placement of each first portion in subsequently generated images to within a desired degree of accuracy, and adjusting the placement of the first portion of each subsequently generated image by the determined shift amounts.

  • Publication number: 20070040363
    Abstract: Side impact airbag system for a vehicle includes a side airbag arranged to deploy along a left or right side of the vehicle and an electronic crash sensor. The electronic crash sensor includes a housing, a mass arranged within the housing to be movable in a lateral direction relative to the housing in response to lateral accelerations of the housing, and a control mechanism for controlling deployment of the side airbag and which is responsive to the motion of the mass only in the lateral direction. The housing is mounted in such a position and a direction as to sense an impact into a side of the vehicle resulting in lateral acceleration of the housing. The electronic crash sensor may generate a signal representative of the movement of the mass.

    Abstract: A printing system and method is provided. The printing system includes one or more printing system modules, at least one media sheet path interfacing the printing system modules, and a job scheduler for executing one or more printing system print jobs. The job scheduler routes a media sheet to one or more printing system modules for preshrinking or preenlarging without marking and subsequently routes the preshrunk or preenlarged media sheet to one or more printing system modules for marking. The method of printing includes generating a print job to be printed using one or more printing system modules. Print jobs requiring two or more printing system modules for marking are executed by routing a media sheet to one or more printing system modules for preshrinking or preenlarging without marking, and subsequently routing the preshrunk or preenlarged media sheet to the one or more printing modules for marking.

    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 includes 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 includes 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: 7070202
    Abstract: Vehicle including a side impact sensor system having a longitudinally extending outer skin arranged on a side of the vehicle, a system housing arranged inward of the outer skin and having an opening facing a portion of a passenger compartment, an inflatable airbag arranged in the system housing, an inflator arranged in connection with the system housing, and a sensor system for detecting an impact into a side of the vehicle. The sensor system includes a sensor housing and a mass arranged therein and movable relative thereto housing in response to acceleration in excess of a threshold value. Movement of the mass relative to the sensor housing provides an indication of a side impact for which deployment of the airbag is desired. The inflator is actuated in response to a side impact by the sensor system in order to expel the airbag through the opening into the passenger compartment.

  • Patent number: 7052038
    Abstract: A vehicle including a side impact crash sensor, a transfer structure interposed between the side of the vehicle and the sensor and an occupant restraint system such as a side impact airbag system. When an object strikes the side of the vehicle or vice versa, the transfer structure serves to transfer the lateral force from the side of the vehicle to the sensor and is designed so that it does not distort upon the application of the lateral force. The side impact crash sensor detects the force or acceleration applied to the side of the vehicle, and the airbag system connected to the sensor deploys an airbag based on the detected force or acceleration. The transfer structure may be constructed to account for mismatch between the point of impact of an object on the side of the vehicle and the location of the sensor.
