A human activity recognition privacy protection method and system for a wearable device

This invention discloses a method and system for protecting privacy in wearable devices for human activity recognition, aiming to solve the problems of existing methods struggling to balance privacy and utility, and high resource consumption on the edge. The method first acquires multi-channel time-series signals from the wearable device and constructs fixed-length feature vectors. Based on a sensitive attribute inference model and the number of high-risk features, it divides the device into high-risk and low-risk feature sets. Only the high-risk feature sub-vectors are subjected to perturbation noise to generate perturbation latent representations, which are then uploaded to an edge server along with the low-risk feature set. The edge server generates the final feature vectors and assesses the risk of privacy leakage. An offline evaluation is used to construct a privacy-utility trade-off, dynamically adjusting the perturbation dimension and noise amplitude. This invention achieves targeted protection of high-risk features, maximizing the preservation of key recognition information, reducing edge computing power and communication overhead, adapting to the differentiated needs of different scenarios, and balancing privacy security and activity recognition performance.

A type of integrated distribution box

This invention relates to the field of power equipment technology, and more particularly to an integrated distribution box. The invention utilizes a movable partition plate within the ventilation cavity, constrained by a guiding component and reset by an elastic element. The sudden change in pressure difference between the inside and outside of the box serves as the driving force, causing the partition plate to shift and instantaneously reduce the flow gap within the ventilation cavity, thereby significantly increasing the equivalent flow resistance of the lateral flow channel. This adaptive variable damping mechanism effectively suppresses the "pumping effect" caused by air pressure pulsations, preventing the instantaneous large-scale intake of external moisture and dust. It automatically resets after the pressure difference stabilizes to ensure normal heat dissipation. Simultaneously, the staggered arrangement of the perforation array forms a physical maze, achieving an automatic balance and consideration of dynamic protection level and heat dissipation efficiency without electrical control intervention.

This utility model belongs to the field of air source heat pump technology, specifically an air source heat pump condensate drainage structure. It includes a rotating shaft, with a drainage base mounted on one end of the shaft. A movable rod is mounted inside the mounting base via a pin. A ball bearing is movably mounted inside a groove, and a cylinder is mounted on the top side of the ball bearing. A circular block is mounted on one end of the movable rod, and a spring is fixed between the circular block and the bottom of the cylinder. A drain pipe is connected to the other side of the drainage base. When condensate accumulates, the increased weight of the drainage base puts pressure on the movable rod, compressing the spring and causing one end of the drainage base to sink, ensuring sufficient water storage. As condensate is continuously drained, the weight of the water on the base decreases, and the compressed spring releases its elastic potential energy, pushing the circular block upwards. The drainage base returns to a certain tilt angle, allowing condensate to slowly flow into the drain pipe along the tilted surface. This achieves a dynamic balance between the tilted drainage and water storage functions of the drainage base, improving drainage efficiency.
