Publication number: 20240135656Abstract: A cross reality system enables portable devices to access stored maps and efficiently and accurately render virtual content specified in relation to those maps. The system may process images acquired with a portable device to quickly and accurately localize the portable device to the persisted maps by constraining the result of localization based on the estimated direction of gravity of a persisted map and the coordinate frame in which data in a localization request is posed. The system may actively align the data in the localization request with an estimated direction of gravity during the localization processing, and/or a portable device may establish a coordinate frame in which the data in the localization request is posed aligned with an estimated direction of gravity such that the subsequently acquired data for inclusion in a localization request, when posed in that coordinate frame, is passively aligned with the estimated direction of gravity.Type: ApplicationFiled: December 26, 2023Publication date: April 25, 2024Applicant: Magic Leap, Inc.Inventors: Javier Victorio Gomez Gonzalez, Miguel Andres Granados Velasquez, Mukta Prasad, Dominik Michael Kasper, Eran Guendelman, Keng-Sheng Lin

Publication number: 20240135707Abstract: To determine the head pose of a user, a head-mounted display system having an imaging device can obtain a current image of a real-world environment, with points corresponding to salient points which will be used to determine the head pose. The salient points are patch-based and include: a first salient point being projected onto the current image from a previous image, and with a second salient point included in the current image being extracted from the current image. Each salient point is subsequently matched with real-world points based on descriptor-based map information indicating locations of salient points in the real-world environment. The orientation of the imaging devices is determined based on the matching and based on the relative positions of the salient points in the view captured in the current image. The orientation may be used to extrapolate the head pose of the wearer of the head-mounted display system.Type: ApplicationFiled: October 8, 2023Publication date: April 25, 2024Inventors: Martin Georg Zahnert, Joao Antonio Pereira Faro, Miguel Andres Granados Velasquez, Dominik Michael Kasper, Ashwin Swaminathan, Anush Mohan, Prateek Singhal

Patent number: 11935180Abstract: Examples of the disclosure describe systems and methods for presenting virtual content on a wearable head device. In some embodiments, a state of a wearable head device is determined by minimizing a total error based on a reduced weight associated with a reprojection error. A view reflecting the determined state of the wearable head device is presented via a display of the wearable head device. In some embodiments, a wearable head device calculates a preintegration term based on the image data received via a sensor of the wearable head device and the inertial data received via a first IMU and a second IMU of the wearable head device. The wearable head device estimates a position of the device based on the preintegration term, and the wearable head device presents the virtual content based on the position of the device.Type: GrantFiled: April 7, 2022Date of Patent: March 19, 2024Assignee: Magic Leap, Inc.Inventors: Yu-Hsiang Huang, Evan Gregory Levine, Igor Napolskikh, Dominik Michael Kasper, Manel Quim Sanchez Nicuesa, Sergiu Sima, Benjamin Langmann, Ashwin Swaminathan, Martin Georg Zahnert, Blazej Marek Czuprynski, Joao Antonio Pereira Faro, Christoph Tobler, Omid Ghasemalizadeh

Patent number: 9166922Abstract: A communication device for an industrial communication network which can be operated in a redundant manner comprises a first and a second transmitting and receiving unit that transmit data packets in a bumpy or bumpless manner inside the industrial communication network and are selectively changeable over to a bumpy or bumpless transmission mode. An evaluation unit is connected to the first and/or second transmitting and receiving unit(s) and detects data packets to be transmitted in the bumpy or bumpless manner inside the industrial communication network. Redundancy handling and filter units for received redundant data packets are deactivated when a data packet to be transmitted in the bumpy manner is detected. A memory unit is assigned to the first and/or second transmitting and receiving unit(s) and buffers at least one data packet to be transmitted in the bumpy manner during a predefined period of time in the bumpy transmission mode.Type: GrantFiled: April 24, 2013Date of Patent: October 20, 2015Assignee: Siemens AktiengesellschaftInventors: Hermann Angst, Franz-Josef Götz, Michael Kasper, Joachim Lohmeyer

Patent number: 8986602Abstract: The reactor is used for producing nano-particles of metal from volatile moieties in flow through mode. The reactor comprises at least a first feeder and a second feeder on one end of the vessel. The first feeder feeds the moiety in the form of an educt fluid into the reactor. This fluid is a mixture of metal moieties and a bearer fluid, entering the reactor in a vaporized state, in which the bearer fluid is used as a carrier gas. The second feeder is used as a radiator means to heat up the educt fluid within the reactor. By providing the heating fluid through the second feeder control over some environmental conditions like ambient temperature within the reactor is achieved and dissociation of the metal moieties under such controlled conditions leads to quantitative production of selected nano-particle morphologies.Type: GrantFiled: August 29, 2011Date of Patent: March 24, 2015Assignee: Directa Plus S.p.A.Inventors: Robert Mercuri, Michael Kasper, Emilie Bekaert, Peter Axmann
