Patent number: 11789996Abstract: Embodiments of the present disclosure provide systems, methods, and computer storage media for implementing a nuanced-color search and recommendation system. Employing various techniques described herein, an improved search engine for categorizable items is provided to generate accurate color-based search results and recommendations that are relevant to a nuanced color provided as a search parameter. In various implementations, digital assets that depict categorizable items can be analyzed to characterize the depicted items with, among other things, a particular shade of a determined dominant color. In this way, categorizable items can be searched based at least in part on a selected shade of a particular dominant color to generate a primary search result. In further embodiments, other categorizable items can be generated as recommendations based on characteristics of the primary search result.Type: GrantFiled: May 6, 2022Date of Patent: October 17, 2023Assignee: EBAY INC.Inventors: John Weigel, Niaz Ahamed Khaja Nazimudeen, Padmapriya Gudipati, Timothy Keefer, Fujun Zhong, Ashmeet Singh Rekhi, Kenneth Crookston, Shane Lin, Suchitra Ramesh, Rodolfo Gonzales, Atiq Islam

Patent number: 11086925Abstract: Systems and methods for improving a search process are provided. A networked system accesses, from online sources, fashion trend information including pictures illustrating fashion trends. The networked system determines a plurality of top fashion trends, and extracts, using an image detection algorithm, images of fashion items from a picture associated with each of the top fashion trends. Using the extracted images, the networked system performs an image search for matching inventory items. The networked system then generates and stored a plurality of fashion trend user interfaces, whereby the plurality of fashion trend user interfaces each comprise selectable elements that represent the plurality of top fashion trends. At runtime, the networked system receives an indication to initiate a search for fashion by trends, and in response, accesses the plurality of stored fashion trend user interfaces. One of the plurality of stored fashion trend user interfaces is presented on a user device.Type: GrantFiled: September 24, 2018Date of Patent: August 10, 2021Assignee: eBay Inc.Inventors: Ashmeet Singh Rekhi, Shane Lin, Suchitra Ramesh, An Feng-I Chen, Padmapriya Gudipati, Justin Nicholas House, Kenneth Crookston, John Weigel, Timothy Keefer, Satya Krishna Suman Voleti, Zhe Sun

Patent number: 9267523Abstract: An improved sensor assembly is provided that allows for close proximity detection of one or more objects by isolating a first sensor from a second sensor within the sensor assembly using isolation boots and a unique mounting structure. Each sensor has at least a portion positioned within an isolation boot, and the isolation boots are supported between a base plate and a support plate by one or more base plate ribs and one or more support plate ribs. The sensor is therefore prevented from otherwise contacting the base plate or the support plate.Type: GrantFiled: January 7, 2013Date of Patent: February 23, 2016Assignee: General Electric CompanyInventors: Jonathan Charles Crosby, William John Weigel
