Publication number: US20220029784A1
Application number: 17/498,560

Abstract:
Encryption engines shuffle data segments during encryption and/or decryption, thereby obtaining a random permutation of the data segments to be used during encryption and/or decryption. By shuffling the data during encryption/decryption and using the resulting random permutation for encryption/decryption, the encryption engines obfuscate the power consumption information that attackers might access as part of an SCA. In some examples, the encryption engines perform intra-round shuffling of the input data within a reduced-sized encryption datapath configured to iteratively compute a portion of an encrypted block of data.

Publication number: US20220030377A1
Application number: 17/498,544

Abstract:
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.

Publication number: US20220026663A1
Application number: 17/496,354

Abstract:
A method includes assembling a first lens and a second lens to form a first optical assembly in a first assembly and validation line; testing the first optical assembly in the first assembly and validation line; securing a coupling between the first lens and the second lens if a testing result satisfies a predetermined condition; and disassembling the first optical assembly into the first lens and the second lens if the testing result does not satisfy the predetermined condition; The method also includes prior to stacking the first lens and the second lens to form a second optical assembly, adjusting at least one of an optical center, a tilt, or a polarimetric angle of at least one of the first lens or the second lens in a second assembly and validation line; and stacking the first lens and the second lens to form the second optical assembly.
