Patent number: 11365074Abstract: In an example, a tray cover extender may include a cover rack attached to a movable tray cover such that movement of the cover rack is transferred to a movement of the movable tray cover. Further, the tray cover extender may include a pinion gear operably engaged with the cover rack so as to actuate or move the cover rack if the pinion gear is actuated. The example tray cover extender may also include a tray rack attached to a media tray. The tray rack may actuate or move the pinion gear as the media tray is moved past the pinion gear. The cover rack may extend the movable tray cover from a first position to a second position if the pinion gear actuates the cover rack.Type: GrantFiled: July 31, 2017Date of Patent: June 21, 2022Assignee: Hewlett-Packard Development Company, L.P.Inventors: Xiaoxi Huang, Deming Xu

Patent number: 11210348Abstract: The present disclosure provides a data clustering method based on K-nearest neighbor, which sorts data points to be clustered in ascending order according to the maximum radiuses of K-nearest neighbors of the data points, that is, according to the density, and perform the first pass across the data points after sorting the data points in ascending order to incorporate the data points that conform to the statistical similarity into the same cluster; then perform the second pass across the data points with smaller cluster density according to the scale required during the clustering to find out all noise points and incorporate non-noise points into the nearest large-density cluster, so as to realize data clustering, which has the benefits of no need to preset the number of clusters and know the probability distribution of the data and convenience to set parameters.Type: GrantFiled: April 27, 2019Date of Patent: December 28, 2021Assignee: HUIZHOU UNIVERSITYInventors: Jinqiu Huang, Deming Xu, Changlin Wan

Patent number: 10471749Abstract: Examples of a hinge set for used for mounting a protractible component of a device are described herein. In an example, the hinge set comprises a support hinge and a guide hinge, each having a first end and a second end. The first end of the support hinge is to pivotably couple to the protractible component and the second end of the support hinge is pivotably coupled to a frame of the device. Further, the first end of the guide hinge is to guide the protractile component and the second end of the guide hinge is to pivotably couple to the frame.Type: GrantFiled: October 30, 2015Date of Patent: November 12, 2019Assignee: Hewlett-Packard Development Company, L.P.Inventors: Deming Xu, Keng San Chia, Jaewan Park, Amy Wan, Chee Hiang Koh

Publication number: 20180174328Abstract: The invention relates to a turning radius-based corner detection algorithm, comprising: S1: removing noise by Gaussian filtering and computing a gradient value of each pixel of an original image; S2: locating a neighboring pixel with closest grayscale to the pixel within given neighborhoods therearound; S3: computing a turning radius between the pixel and the closest neighboring pixel thereof; S4: computing a turning radius threshold; S5: marking a pixel with the turning radius which is greater than the threshold and maximum in the given neighborhoods as a corner. By the solution, the present invention can locate corners in images accurately and restrain fake corners resulting from noises and textures, and also can simplify the computation of the threshold and raise the computation efficiency, whereby automatic detection is realized and effect of corner detection is improved. The invention is applicable to 3D reproduction, visual locating, measurement, etc.Type: ApplicationFiled: May 19, 2016Publication date: June 21, 2018Inventors: Changlin Wan, Deming Xu, Jianzhong Cao, Xiaohui Wei

Publication number: 20150319323Abstract: The disclosure relates to a scantling unit (20) comprising an interlocking assembly (45). The interlocking assembly (45) comprises; an interlock arm (40) pivotably connected to a scanner base of the scanning unit (20) and movable between a locked position and an unlocked position; and a biasing mechanism, for biasing the interlock arm toward the locked position, A combo gear (31) of the scanning unit (20) is locked by the interlocking assembly (45), thereby being prevented from, rotating, before a scan bar driver gear (26) of the scanning unit (20) engages with the combo gear (31) of the scanning unit (20).Type: ApplicationFiled: January 21, 2013Publication date: November 5, 2015Applicant: HEWLETT-PACKARD DEVELOPMENT COMPANY, L.P.Inventors: Deming XU, Xiao-Hua ZHOU, Song ZHANG
