Patent number: 11176396Abstract: First and second confidence values are determined. The first confidence value corresponds to a likelihood that, from a position and an orientation of a mobile computing device, the mobile computing device is pointing to a visual code. The second confidence value corresponds to a likelihood that, from an image captured by the mobile computing device, the mobile computing device is pointing to the visual code. Whether the mobile computing device is pointing to the visual code is determined based on the first confidence value and the second confidence value.Type: GrantFiled: June 29, 2017Date of Patent: November 16, 2021Assignee: Hewlett-Packard Development Company, L.P.Inventors: Lucio Polese Cossio, Renato Oliveira da Silva

Patent number: 11176238Abstract: In some examples, a mobile device registers an account of a first service with an account control service, the account control service separate from the first service. In response to the mobile device being authorized with respect to the account control service, the mobile device searches for a target device that is within a communication range of the mobile device. The mobile device transmits, to the target device found in the search, a credential of the account of the first service being accessed by the target device over a network.Type: GrantFiled: July 12, 2016Date of Patent: November 16, 2021Assignee: Hewlett-Packard Development Company, L.P.Inventors: Lucio Polese Cossio, Fernanda Maira Gallina, Renato Oliveira da Silva, Alan Brochier

Publication number: 20210197462Abstract: In one example, a topographic build plate for an additive manufacturing system. The build plate is to support a 3D object fabricated layer-by-layer, and is divided into plural blocks each having a build surface. In-between fabrication of layers of the object, a first one of the blocks is offset in a Z-direction from a second one of the blocks to position the build surfaces of the first and second blocks at different Z-direction locations to replace at least a portion of a support structure of the 3D object.Type: ApplicationFiled: January 31, 2017Publication date: July 1, 2021Applicant: HEWLETT-PACKARD DEVELOPMENT COMPANY, L.P.Inventors: Alan BROCHIER, Gustavo CALLEGARI, Lucio POLESE COSSIO, Fernanda Maira GALLINA, Renato OLIVEIRA DA SILVA

Patent number: 10872113Abstract: Techniques are described herein for image recognition and retrieval. A system for image recognition and retrieval includes an imager to capture a plurality of image frames. The system also includes an image eliminator to discard any image frame of the plurality of image frames that does not meet a specified quality threshold. A remaining set of image frames is obtained. An image grouper groups the remaining set of image frames into groups of a specified number. A group of image frames is obtained. The system further includes a feature identifier to identify and describe features of the group of image frames. A requester sends a query to a content-based image retrieval server. The query contains descriptors for the features of the group of image frames.Type: GrantFiled: July 19, 2016Date of Patent: December 22, 2020Assignee: Hewlett-Packard Development Company, L.P.Inventors: Andre Rabelo, Lucio Polese Cossio, Renato Oliveira da Silva, Edwin Csrlo Ribeiro Marinho, Fernanda Vieira de Barros Almeida, Fäbio Almeida Melo, Victor Hazin da Rocha, Deise Miranda Borges

Patent number: 10244358Abstract: Mostly, motion signals are inaccurate, especially if the mobile device is not a proprietary device, and one has to reckon that the bearer wears the mobile device somewhere else than where it is supposed to be worn in order to coincide with the laboratory conditions. However, the information conveyed by the motion signals is sufficient in order to discriminate and detect between different typical wearing/carrying conditions, and accordingly position tracking based on such motion signals may be rendered far more efficiently by, first of all, using the motion signals gained from the one or more motion sensors so as to attribute them to one of a plurality of analysis parameter sets so as to obtain a selected analysis parameter set and, second, analyzing the motion signals using the selected analysis parameter set so as to obtain a signal indicating a locomotion of the bearer.Type: GrantFiled: September 24, 2018Date of Patent: March 26, 2019Assignee: Fraunhofer Portugal ResearchInventors: Dirk Elias, Vânia Guimarães, Bruno Aguiar, Lourenço Castro, David Ribeiro, Manuel Monteiro, Tiago Rocha, Carlos Ferreira, Susana Carneiro, André Costa Lima, Joana Silva, Renato Oliveira

Patent number: 9704210Abstract: In one example, a system including an isolation engine, a normalization engine, and a channel engine is described. In the example, the isolation engine generates mark data using a mark technique based on a first input color channel and a second input color channel, the normalization engine scales intensity values of a set of pixels of the mark data to a greater range, and the channel engine generates output channel data for a plurality of output color channels from normalized mark data based on the scaled intensity values.Type: GrantFiled: November 30, 2015Date of Patent: July 11, 2017Assignee: Hewlett-Packard Development Company, L.P.Inventors: Renato Oliveira da Silva, Lucio Cossio
