Patent number: 11600084Abstract: A method of price text detection by an imaging controller comprises obtaining, by the imaging controller, an image of a shelf supporting labels bearing price text, generating, by the imaging controller, a plurality of text regions containing candidate text elements from the image, assigning, by the imaging controller, a classification to each of the text regions, selected from a price text classification and a non-price text classification. The imaging controller, within each of a subset of the text regions having the price text classification: detects a price text sub-region and generates a price text string by applying character recognition to the price text sub-region. The method further includes presenting, by the imaging controller, the locations of the subset of text regions, in association with the corresponding price text strings.Type: GrantFiled: May 5, 2017Date of Patent: March 7, 2023Assignee: Symbol Technologies, LLCInventors: Mingxi Zhao, Yan Zhang, Kevin J.

Publication number: 20210017552Abstract: Disclosed herein is a method for effecting atom or group transfer polymerization comprising polymerizing one or more radically-polymerizable monomers in the presence of a system comprising an electrically active micro-organism, a transition metal catalyst, one or more radically-polymerizable monomers, and a radical initiator. Micro-organism respiratory electron flux is harnessed to control the performance of a metal-catalyzed polymerization. The bacterial electron transport pathways of the electroactive micro-organisms can be engineered to tune and adapt various function of the electroactive micro-organism and its role in polymerization. Polymerization may be accomplished under aerobic or anaerobic conditions. Freshly cultured micro-organisms or lyophilized micro-organisms may be used to direct polymerization.Type: ApplicationFiled: March 26, 2019Publication date: January 21, 2021Inventors: Benjamin KEITZ, Gang FAN, Chris DUNDAS, Austin GRAHAM, Nathaniel LYND
