Title: Alaa Khaddaj: Innovator in Radio Frequency Sensing

Introduction

Alaa Khaddaj is a notable inventor based in Cambridge, MA (US). He has made significant contributions to the field of radio frequency sensing, with a focus on innovative methods and apparatuses that enhance the understanding of contents within closed containers.

Latest Patents

Alaa Khaddaj holds two patents, both centered around methods and apparatus for radio frequency sensing in diverse environments. His latest patent describes a system that can sense the contents of a closed container by analyzing a wireless signal that reflects from an RFID tag on the outside of the container. The frequency response of the tag's antenna is influenced by the relative permittivity of the contents and the tag's environment. This frequency response can be measured in both line-of-sight and multipath environments. Channel estimates are calculated based on these measurements, and channel ratios are derived by dividing line-of-sight channel estimates by multipath channel estimates. The resulting channel ratios are then fed into a variational autoencoder, which generates synthetic data that contains information about multipath environments but not the contents. The output of the variational autoencoder can be converted into synthetic channel estimates, which may be utilized for anomaly detection or to train a classifier to identify the contents of the container.
