Publication number: 20240037254Abstract: In one embodiment, a device may extract, from one or more bodies of text, a data usage restriction for a particular type of data. The device may send, to a user interface, the data usage restriction extracted from the one or more bodies of text for presentation for a user. The device may receive, via the user interface, feedback from the user regarding the data usage restriction. The device may generate a data compliance constraint that controls how an application service handles the particular type of data, based on the data usage restriction and the feedback from the user.Type: ApplicationFiled: July 29, 2022Publication date: February 1, 2024Inventors: Marcelo Yannuzzi, Arash Salarian, Herve Muyal, Jean Andrei Diaconu, Jelena Kljujic, Carlos Goncalves Pereira

Patent number: 11763814Abstract: Digitized audio command is decoded to generate audio features. An in-domain confidence score is calculated for a model trained by a limited set of peripheral device commands. An out-domain confidence score is calculated for a model trained without the peripheral device commands. The best score determines whether to process the audio locally or at a remote server. In some embodiments, a likelihood ratio (LR) is calculated of the in-domain and out-domain confidence scores. Based on the likelihood ratio, a locally decoded audio command is performed, or the audio features are sent to a remote server for processing to determine the audio command.Type: GrantFiled: June 21, 2021Date of Patent: September 19, 2023Assignee: Logitech Europe S.A.Inventors: Arash Salarian, Milos Cernak, Pablo Mainar, Jean-Michael Chardon, Niccolò Antonello

Publication number: 20210216135Abstract: An AR/VR input device include a processor(s), an internal measurement unit (IMU), and a plurality of sensors configured to detect emissions received from a plurality of remote emitters. The processor(s) can be configured to: determine a time-of-flight (TOF) of the detected emissions, determine a first estimate of a position and orientation of the input device based on the TOF of a subset of the detected emissions and the particular locations of each of the plurality of sensors on the input device that are detecting the detected emissions, determine a second estimate of the position and orientation of the input device based on the measured acceleration and velocity from the IMU, and continuously update a calculated position and orientation of the input device within the AR/VR environment in real-time based on a Beyesian estimation (e.g., Extended Kalman filter) that utilizes the first estimate and second estimate.Type: ApplicationFiled: March 29, 2021Publication date: July 15, 2021Inventors: Andreas Connellan, Arash Salarian, Fergal Corcoran, Jacques Chassot, Jerry Ahern, Laleh Makarem, Mario Gutierrez, Maxim Vlasov, Olivier Guédat, Padraig Murphy, Richard Peter Perring

Patent number: 9658701Abstract: Embodiments of the invention are directed to input devices configured for use with computing devices. The present invention relates to input devices configured with a plurality of sensors configured to determine the displacement and position of the input device. Tracking of the input device may be switched from an optical sensor to an inertial sensor based on the speed of movement of the input device or based on the input device detecting that loss of tracking has occurred. In some embodiments, a gyroscope may be configured to modify data from the inertial sensor module to correct for fictitious accelerations generated when the input device is rotated.Type: GrantFiled: January 27, 2014Date of Patent: May 23, 2017Assignee: Logitech Europe S.A.Inventors: Arash Salarian, Nicolas Chauvin, David Tarongi Vanrell
