Publication number: 20220118709Abstract: In an example, a method includes segmenting, using a processor, a virtual volume comprising a representation of at least a part of an object to be generated in additive manufacturing. The virtual volume may be segmented into a plurality of segments and the object may be intended to have a first color. Additive manufacturing control instructions may be determined for the segments. The additive manufacturing control instructions may comprise instructions for distributing the print agent composition and the additive manufacturing control instructions for each segment may be determined based on the thermal properties of a print agent composition intended to provide the first color to compensate for variations in object dimensions associated with the thermal properties.Type: ApplicationFiled: July 8, 2019Publication date: April 21, 2022Applicant: Hewlett-Packard Development Company, L.P.Inventors: Matthew A.

Publication number: 20220083023Abstract: According to examples, an apparatus may include a processor and a memory on which are stored machine-readable instructions that when executed by the processor, may cause the processor to identify a first orientation of a first surface portion of a three-dimensional (3D) model. The instructions may also cause the processor to, based on the identified first orientation of the first surface portion, determine a first thickness of a first section of a first geological region of the 3D model, the first section being adjacent to the first surface portion, in which a plurality of different orientations of 3D model surface portions are correlated to a plurality of different thicknesses. The instructions may further cause the processor to define the first section of the first geological region to have the determined first thickness.Type: ApplicationFiled: May 3, 2019Publication date: March 17, 2022Applicant: Hewlett-Packard Development Company, L.P.Inventors: Matthew A. Shepherd, Vanessa Verzwyvelt, Jacob Wright, Xin Cheng, Dennis J. Schissler, Morgan T. Schramm

Patent number: 10477054Abstract: In one example, a document scanner has a fixed-position scan bar and a built-in translatable calibration target. The scan bar has a linear array of imaging elements aimed in an imaging direction. The calibration target is spaced apart from and parallel to the linear array, and has a planar surface orthogonal to the imaging direction spanning the length of the linear array. The target is translatable during a calibration in a direction in a plane of the surface.Type: GrantFiled: August 24, 2018Date of Patent: November 12, 2019Assignee: Hewlett-Packard Development Company, L.P.Inventors: Wesley R.

Patent number: 5973815Abstract: A screen-printed reflector reflectively redirects light from a scanner bulb in a substantially uniform illumination pattern across a desired scan area of a document to be scanned. A middle or central portion of the reflector is printed with a non-reflective pattern, while the end portions of the reflector are composed of highly reflective polyester textured matte that in combination with the non-reflective pattern substantially equalizes the illumination across the desired scan area of the document being scanned. The manner of using and constructing the screen printed reflector, provides a fast and efficient method for tuning a light distribution profile to provide a sufficient light reflective pattern that compensates for non-uniform light distribution patterns produced by scanner bulbs.Type: GrantFiled: February 25, 1998Date of Patent: October 26, 1999Assignee: Hewlett-Packard CompanyInventors: Dennis J.
