Publication number: 20240151678Abstract: The invention is notably directed to an oscillating reaction device. The device basically includes a structured layer of a matrix material and structural elements. Cavities are defined (for example, as blind holes) in the structured layer to allow the cavities to be filled with an oscillating reaction liquid containing nonpolar molecules of a given molecular species, with a view to triggering an oscillating reaction. Centers of the cavities are arranged according to a 2D lattice, whereby pairs of nearest-neighbor cavities of said cavities are, each, separated by a portion of the matrix material. This portion of material is selectively permeable to said nonpolar molecules. This, in operation, yields an inhibitory chemical coupling of the filled cavities of said pairs of nearest-neighbor cavities, where the inhibitory chemical coupling is mediated by said nonpolar molecules. Also, the structural elements connect the cavities to yield a positive chemical coupling of the filled cavities.Type: ApplicationFiled: November 7, 2022Publication date: May 9, 2024Inventors: Armin Knoll, Heiko Wolf, Philippe Marc Nicollier, Daniel Widmer, Jacqueline Figueiredo da Silva

Publication number: 20240031678Abstract: A method and apparatus of tracking poses of a rolling-shutter camera in an augmented reality (AR) system is provided. The method and apparatus use camera information and inertial sensor readings from Inertial Measurement Unit (IMU) to estimate the pose of the camera at a reference line. Thereafter, relative pose changes at scanlines may be calculated using the inertial sensor data. The estimated reference pose of the camera is then further refined based on the visual information from the camera, the relative pose changes and the optimized reference line pose of a previous image. Thereafter, the estimate of the scanline poses may be updated using the relative pose changes obtained in the earlier steps.Type: ApplicationFiled: October 2, 2023Publication date: January 25, 2024Inventors: Georg Halmetschlager-Funek, Jeroen Hol, Matthias Kalkgruber, Nikolaj Kuntner, Daniel Wolf

Publication number: 20230350206Abstract: Devices and methods for dynamic power configuration (e.g., reduction) for thermal management (e.g., mitigation) in a wearable electronic device such as an eyewear device. The wearable electronic device monitors its temperature and, responsive to the temperature, configures the services it provides to operate in different modes for thermal mitigation (e.g., to prevent overheating). For example, based on temperature, the wearable electronic device adjusts sensors (e.g., turns cameras on or off, changes the sampling rate, or a combination thereof) and adjusts display components (e.g., adjusted rate at which a graphical processing unit generates images and a visual display is updated). This enables the wearable electronic device to consume less power when temperatures are too high in order to provide thermal mitigation.Type: ApplicationFiled: July 6, 2023Publication date: November 2, 2023Applicant: Snap Inc.Inventors: Sumant Hanumante, Bernhard Jung, Matthias Kalkgruber, Anton Kondratenko, Edward Lee Kim-Koon, Gerald Nilles, John James Robertson, Dmitry Ryuma, Alexander Sourov, Daniel Wolf

Publication number: 20230205311Abstract: A method for calibrating a visual-inertial tracking system is described. A device operates the visual-inertial tracking system without receiving a tracking request from a virtual object display application. In response to operating the visual-inertial tracking system, the device accesses sensor data from sensors at the device. The device identifies, based on the sensor data, a first calibration parameter value of the visual-inertial tracking system and stores the first calibration parameter value. The system detects a tracking request from the virtual object display application. In response to the tracking request, the system accesses the first calibration parameter value and determines a second calibration parameter value from the first calibration parameter value.Type: ApplicationFiled: March 2, 2023Publication date: June 29, 2023Inventors: Georg Halmetschlager-Funek, Matthias kALKGRUBER, Daniel Wolf, Jakob Zillner
