Latest Patents

Among Jiajin An's latest patents is a groundbreaking system for user voice activity detection in headsets. Many devices equipped with automatic noise cancellation (ANC) technology fall short as their voice microphones tend to pick up ambient noise. An's invention provides a solution by automatically muting and unmuting the voice microphone based on the user's speech, thus improving communication clarity without requiring manual operation. Furthermore, this innovation intelligently utilizes relationships between feedback and feedforward signals in ANC circuitry, minimizing the need for additional hardware.

Another notable patent addresses earbud operation during earbud insertion detection. This method allows headphones to generate input signals that determine whether they are being worn. If no insertion event is detected after a set period, the headphones enter a low power mode, conserving battery life. After a further extended period without detection, they transition into an ultra-low power mode, significantly reducing power consumption while maintaining functionality.
