Retractable AntennaMagnetic GuidingRF Cable Protection

This patent describes an electronic device with a movable component (like a camera) that carries an antenna radiator. To maintain high radiation efficiency, the device adjusts the position of the movable component to ensure a large antenna clearance area. A key feature is a magnetic guiding mechanism that controls the movement of the RF cable as the component retracts. This prevents the cable from tangling or sustaining bending damage during frequent extensions and retractions, ensuring stable connection quality while supporting high screen-to-body ratio designs.

Antenna DesignSAR ReductionIntegrated Housing

This invention focuses on reducing the Specific Absorption Rate (SAR) of antennas in electronic devices without compromising Total Radiated Power (TRP). The antenna radiator, integrated into the device's frame, features a specific vacancy area or cutout. This gap is strategically placed within the high-current region of the radiator, typically on the side facing the user. By altering the electric field distribution, it shifts the SAR hotspots away from the user, effectively lowering radiation absorption while maintaining stable wireless communication performance for narrow-bezel mobile devices.

Smart ToiletEnergy SavingProximity Sensing

This application provides a power management system for smart toilets to reduce energy consumption from features like seat heating. The toilet establishes a wireless connection with a user device to track its location. Based on distance thresholds, the toilet switches between power-saving and pre-heating modes. If the user is far away, the device enters energy-saving mode; as they approach, it begins pre-heating. Advanced versions use historical usage data to predict active periods, ensuring the toilet is ready when needed while minimizing idle power waste.
