Introduction

Yuwei Liao is a prominent inventor based in Cary, NC (US), known for his contributions to wearable technology and grid monitoring systems. With a total of 7 patents, Liao has made significant strides in enhancing the accuracy and efficiency of heart-rate detection systems and monitoring grid devices.

Latest Patents

One of Liao's latest patents is focused on robust heart-rate detection techniques for wearable heart-rate sensors. This innovative system receives heartbeat data from a wearable sensor and executes a noise-reduction process to enhance the quality of the data. The process involves applying a lowpass filter, generating wavelet coefficients through a wavelet transform, and creating a reduced set of coefficients via thresholding. An inverse wavelet signal is then produced, allowing for the identification of R-peaks through peak detection. Ultimately, a heart rate curve is generated and modified using a Hampel filter to produce accurate heartbeat data for output.

Another notable patent is a grid status monitoring system that utilizes computer technology to monitor the status of grid devices through sensor measurements. The system clusters sensor data and monitored devices based on predefined distance values, allowing for efficient asset management. By computing distances between sensor event clusters and asset clusters, the system can generate an asset event list, which is visually represented on a map in a graphical user interface.
