Latest Patents

His latest patents focus on methods and apparatus for radio frequency sensing in diverse environments. One of the key innovations involves a system that can sense the contents of a closed container by analyzing a wireless signal reflecting from an RFID tag on the outside. The frequency response of the tag's antenna is influenced by the relative permittivity of the contents and the tag's environment. Measurements can be taken 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. These channel ratios are then processed through a variational autoencoder, which generates synthetic data that provides insights into multipath environments without revealing the contents. The output can be transformed into synthetic channel estimates, which are useful for anomaly detection or training classifiers to identify the contents of the container.
