Patent number: 11861873Abstract: One implementation involves a device receiving a stream of pixel events output by an event camera. The device derives an input image by accumulating pixel events for multiple event camera pixels. The device generates a gaze characteristic using the derived input image as input to a neural network trained to determine the gaze characteristic. The neural network is configured in multiple stages. The first stage of the neural network is configured to determine an initial gaze characteristic, e.g., an initial pupil center, using reduced resolution input(s). The second stage of the neural network is configured to determine adjustments to the initial gaze characteristic using location-focused input(s), e.g., using only a small input image centered around the initial pupil center. The determinations at each stage are thus efficiently made using relatively compact neural network configurations. The device tracks a gaze of the eye based on the gaze characteristic.Type: GrantFiled: August 5, 2022Date of Patent: January 2, 2024Assignee: Apple Inc.Inventors: Thomas Gebauer, Raffi Bedikian

Patent number: 11740166Abstract: Disclosed herein is a method for determining elastic properties of a test body by the use of tensile or compressive loading in a test stand, wherein a centroid line is defined for a longitudinal axis for the test body, centroid line miming through elastic centers of gravity of infinitesimally thick discs which lie orthogonally to the longitudinal axis and into which the test body can be divided. The test body is clamped at two clamping points by clamping devices, and a force is introduced at, at least one of the two clamping points in the direction of the respective other clamping point such that a line of action of a force introduced at, at least one of the clamping points is substantially parallel to a connection line between the two clamping points. Furthermore, by providing additional material or springs to the test body, the center of gravity line of the test body is converted into a modified centroid line of the entire system consisting of the test body and additional material or springs).Type: GrantFiled: November 2, 2018Date of Patent: August 29, 2023Assignee: Fraunhofer-Gesellschaft zur Förderung der angewandten Forschung e.V.Inventors: Malo Rosemeier, Thomas Gebauer

Patent number: 11734570Abstract: The present disclosure describes techniques for training a neural network such that the trained network can be implemented to perform a utility task (e.g., a classification task) while inhibiting performance of a secondary task (e.g., a privacy-violating task). In some embodiments, the techniques include training a neural network using a first loss associated with a first task and a second loss associated with a second task different from the first task. In some embodiments, this includes performing a first training operation associated with the first loss, and performing a second training operation associated with the second loss, wherein the second training operation includes providing, to the neural network, a plurality of input items associated with the second task.Type: GrantFiled: October 29, 2019Date of Patent: August 22, 2023Assignee: Apple Inc.Inventors: Daniel Kurz, Thomas Gebauer, Dewey H.
