Abstract
This page connects the engineering question, system architecture, implementation, measurements, figures, code, and follow-up work behind each project. The same reading order is used for research projects, conference papers, coursework, technical notes, and external training so that a visitor can move from the question to the actual output without searching through separate archives.
Research Map
Radar · Biomedical Signal Processing
600 seconds of concurrent ECG, SCG, and FMCW radar acquisition. AO/AC candidate timing across 848 corresponding beats.

Public details will be expanded after disclosureMethodology
Define the signal, interface, constraint, and failure condition.
Separate sensing, processing, communication, control, and outputs.
Build firmware, RTL, signal processing, models, and UI paths.
Use synchronized data, reference models, regression, and failure tests.
Publish figures, code, papers, reports, and reproducible links.

Image Gallery
Where a publication-style architecture figure is missing, the site uses a source-based SVG/HTML diagram first. Final figures are published only after their labels, arrows, components, and values match the underlying material.
