Publication number: 20240359578Abstract: A system may include an energy provision system, a first converter, a second converter, a traction system, and an auxiliary system. The energy provision system may provide a first voltage. The first converter may increase the first voltage from the energy provision system from the first voltage into at least a second voltage. The traction system of a vehicle may be powered by the second voltage from the first converter. The second converter may decrease the first voltage from the energy provision system from the first voltage to a third voltage which may be less than the second voltage. The auxiliary system of the vehicle may be powered by the third voltage from the second converter that may be less than the second voltage.Type: ApplicationFiled: April 25, 2024Publication date: October 31, 2024Applicant: Transportation IP Holdings, LLCInventors: Henry Todd Young, Jason Daniel Kuttenkuler, Daniel Robert Wallace, David Andrew Ryan, Jeffrey John Wolff

Publication number: 20240354298Abstract: The methods and systems for improving communication distribution. In particular, the methods and systems for improving communication distribution in environments where there is both the need for end-user specific data (e.g., customized content) and/or data storage constraints. For example, in order to address the security/privacy concerns during communication distribution, the methods and systems use a novel architecture that limits the amount of data that must be stored. Specifically, the system does not require permanent storage of communications featuring end-user specific data prior to the distribution of these communications. Accordingly, the storage requirements are greatly diminished, and privacy/security concerns are avoided.Type: ApplicationFiled: June 28, 2024Publication date: October 24, 2024Inventors: John WOLFF, Ruiyi ZHU, Marc RIVA, Natasha HORN, Vasanthi BHEEMAVARAPU, Robert COSTANTINO

Patent number: 12079978Abstract: This invention provides a system and method for determining the location and characteristics of certain surface features that comprises elevated or depressed regions with respect to a smooth surrounding surface on an object. A filter acts on a range image of the scene. A filter defines an annulus or other perimeter shape around each pixel in which a best-fit surface is established. A normal to the pixel allows derivation of local displacement height. The displacement height is used to establish a height deviation image of the object, with which bumps, dents or other height-displacement features can be determined. The bump filter can be used to locate regions on a surface with minimal irregularities by mapping such irregularities to a grid and then thresholding the grid to generate a cost function. Regions with a minimal cost are acceptable candidates for application of labels and other items in which a smooth surface is desirable.Type: GrantFiled: November 15, 2021Date of Patent: September 3, 2024Assignee: Cognex CorporationInventors: Mikhail Akopyan, Lowell D.

Patent number: 11562502Abstract: This invention provides an easy-to-manufacture, easy-to-analyze calibration object which combines measurable and repeatable, but not necessarily accurate, 3D features—such as a two-sided calibration object/target in (e.g.) the form of a frustum, with a pair of accurate and measurable features, more particularly parallel faces separated by a precise specified thickness, so as to provide for simple field calibration of opposite-facing DS sensors. Illustratively, a composite calibration object can be constructed, which includes the two-sided frustum that has been sandblasted and anodized (to provide measurable, repeatable features), with a flange whose above/below parallel surfaces have been ground to a precise specified thickness. The 3D corner positions of the two-sided frustum are used to calibrate the two sensors in X and Y, but cannot establish absolute Z without accurate information about the thickness of the two-sided frustum; the flange provides the absolute Z information.Type: GrantFiled: May 18, 2020Date of Patent: January 24, 2023Assignee: Cognex CorporationInventors: Aaron S.

Patent number: 11240435Abstract: The techniques described herein relate to methods, apparatus, and computer readable media configured to determine parameters for image acquisition. One or more image sensors are each arranged to capture a set of images of a scene, and each image sensor comprises a set of adjustable imaging parameters. A projector is configured to project a moving pattern on the scene, wherein the projector comprises a set of adjustable projector parameters. The set of adjustable projector parameters and the set of adjustable imaging parameters are determined, based on a set of one or more constraints, to reduce noise in 3D data generated based on the set of images.Type: GrantFiled: September 28, 2020Date of Patent: February 1, 2022Assignee: Cognex CorporationInventors: Robert Wolff, Thomas Penny, Marcus Große

Patent number: 10775160Abstract: This invention provides a system for measuring displacement of an object surface having a displacement sensor that projects a line on the object surface and receives light from the projected line at an imager in a manner defines a plurality of displacement values in a height direction. A vision system processor operates on rows of imager pixels to determine a laser line center in columns of imager pixels in each of a plurality of regions of interest. Each region of interest defines a plurality of rows that correspond with expected locations of the projected line on the object surface. A GUI can be used to establish the regions. In further embodiments, the system generates grayscale images with the imager. These grayscale images can be compared to a generated height image to compensate for contrast-induced false height readings. Imager pixels can be compared to a reference voltage to locate the line.Type: GrantFiled: August 6, 2018Date of Patent: September 15, 2020Assignee: Cognex CorporationInventors: Robert A.

Patent number: 10438036Abstract: This invention provides a system and method for reading and decoding ID features located on a surface of a curved, sloped and/or annular object, such as a tire moving on a conveyor. A plurality of 3D sensors are operatively connected to a vision system processor. The sensors are calibrated by calibration parameters to generate a stitched-together 3D image of a field of view in a common coordinate space. A motion conveyance (e.g. a conveyor) causes the object and the 3D sensors to move in relative motion, and the conveyance provides motion information to the vision system processor. An ID finder locates ID features within a version of the 3D image and a decoder (e.g. an OCR reader) generates data from the ID features. The ID finder can locate a trained portion of the ID and the search for variable code elements at a known orientation relative to the trained portion.Type: GrantFiled: November 9, 2016Date of Patent: October 8, 2019Assignee: Cognex CorporationInventors: Matthew R.
