Publication number: 20240056763Abstract: Embodiments relate to an audio system that performs equalization of audio signals based on one or more diffuse field head-related transfer functions (HRTFs) and device-specific data. User-specific data and device-specific data (i.e., transducer-specific data) are applied to an acoustic model to predict an acoustic response for a user. An equalization filter is then determined using the acoustic response and the one or more diffuse field HRTFs. The equalization filter is applied to a processed version of an audio signal to create a modified version of the audio signal. The modified version of the audio signal is presented to the user via a transducer array of the audio system. The audio system can further include a microphone assembly that reduces the Helmholtz resonance effect.Type: ApplicationFiled: October 25, 2023Publication date: February 15, 2024Inventors: David Brokenshire, Chuankeat Kho, Pablo Francisco Faundez Hoffmann, Chuming Zhao

Patent number: 11579672Abstract: The disclosed computing device may include electronic components, at least one of which is a processor. The computing device may also include a heat sink thermally coupled to the electronic components, as well as a temperature sensor that determines the current temperature inside the computing device. The computing device may further include a controller. The processor may generate a load schedule for the electronic components based on the current temperature inside the computing device. This load schedule ensures that a maximum temperature for the heat sink is not exceeded even when the total system power load exceeds, for a short period of time, the maximum sustainable power level the heat sink can dissipate. The controller may then load the electronic components according to the generated load schedule. Various other methods, systems, and computer-readable media are also disclosed.Type: GrantFiled: November 10, 2021Date of Patent: February 14, 2023Assignee: Meta Platforms, Inc.Inventors: Howard William Winter, Chuankeat Kho, Peter John Richard Gilbert Bracewell
