Title: Liwen Chen - Innovator in Signal Processing and Adhesive Technologies

Introduction: Liwen Chen is a talented inventor based in Shanghai, CN. She is currently employed at Dow Global Technologies LLC, where she contributes her expertise in innovative technologies. Although she has not yet been granted any patents, her work is focused on advancing signal processing methods and adhesive compositions.

Latest Patent Applications: Liwen Chen has filed several notable patent applications. One of her latest applications is for a "Signal Processing Method and Electronic Device." This application discloses various signal processing methods and electronic devices, including a method applied to an electronic device that features a microphone array and a camera. The method involves performing sound source localization on a first audio signal obtained from the microphone array to derive sound source direction information. Additionally, it processes a first video captured by the camera to obtain user direction information. Based on these two sets of information, a target sound source direction is determined, and a user lip video is obtained in that direction. Furthermore, a second audio signal is captured, and a third audio signal is generated using a voice quality enhancement model.

Another significant application is titled "Article with Adhesive Composition Having a Block Composite Compatibilizer." This disclosure presents an article that includes a first substrate made of a first propylene-based polymer and a second substrate made of a second propylene-based polymer. The adhesive composition located between these substrates consists of a block composite compatibilizer, an ethylene-based polymer or a propylene-based polymer, a tackifier, and a wax. This composition enhances the bonding strength between the two substrates, resulting in improved lap shear strength.

Conclusion: Liwen Chen is an innovative inventor whose work in signal processing and adhesive technologies holds great promise for future advancements. Her contributions at Dow Global Technologies LLC reflect her commitment to developing cutting-edge solutions in her field.
