Publication number: 20240127075Abstract: Machine learning is a process that learns a model from a given dataset, where the model can then be used to make a prediction about new data. In order to reduce the costs associated with collecting and labeling real world datasets for use in training the model, computer processes can synthetically generate datasets which simulate real world data. The present disclosure improves the effectiveness of such synthetic datasets for training machine learning models used in real world applications, in particular by generating a synthetic dataset that is specifically targeted to a specified downstream task (e.g. a particular computer vision task, a particular natural language processing task, etc.).Type: ApplicationFiled: June 21, 2023Publication date: April 18, 2024Applicant: NVIDIA CorporationInventors: Shalini De Mello, Christian Jacobsen, Xunlei Wu, Stephen Tyree, Alice Li, Wonmin Byeon, Shangru Li

Patent number: 11837937Abstract: A haptic actuator may include a base, a field member coupled to the base and that may include spaced apart permanent magnets. The haptic actuator may also include a coil having a loop shape defining a slotted opening therein, and a spring member suspending the coil so that the field member is within the slotted opening and permitting relative movement of the field member and the coil.Type: GrantFiled: August 10, 2020Date of Patent: December 5, 2023Assignee: Apple Inc.Inventors: Kathryn K. Wopat, Fu-Ying Huang, Hari Vasudevan, Xin Alice Wu, Shingo Yoneoka

Publication number: 20230006528Abstract: A double helix actuator is disclosed that includes a double helix coil wound around a movable proof mass that is enclosed within a magnetic structure. The double helix coil and the magnetic structure are arranged relative to each other so that the magnetic field generated by the entirety of the double helix coil contributes to a linear force direction of the actuator. The double helix actuator produces a greater linear force density compared to traditional racetrack coil actuators, where only a portion of the coil contributes to the linear force. The double helix actuator also produces torque in addition to linear force which allows the double helix to provide unique haptic sensations in a variety of applications.Type: ApplicationFiled: February 18, 2022Publication date: January 5, 2023Inventors: Jere C. Harrison, Alex J. Speltz, Xin Alice Wu
