Abstract: A serial presence detect (SPD) device includes nonvolatile memory to store SPD information. Parity information suitable for single error correct and double error detect (SEC-DED) is also stored in association with the SPD information in the nonvolatile memory. The combination of SPD information and parity information is organized into codewords addressable at each memory location. During an initialization period occurring after a power on reset and before the SPD device is accepting I2C commands, the SPD device checks each memory location (codeword) for errors. Each error detected is counted to provide an indicator of device health. Before the initialization period expires, the SPD device writes a corrected codeword back to the nonvolatile memory.

Abstract: This invention relates to a self-supervised privacy preservation action recognition system leveraging a learnable transformation anonymization function. The system is designed to process videos by removing spatial cues to protect privacy while retaining critical information for action recognition. The anonymization function, based on an encoder-decoder model, undergoes iterative training on a dataset to optimize the balance between obscuring privacy-sensitive information and preserving capability of recognizing actions. This training involves freezing and adjusting the weights of an action recognition branch and a self-supervised privacy removal branch to refine the model's effectiveness. The outcome is an anonymized video with minimized privacy information leakage, suitable for action analysis without privacy labels.
