Latest Patents

Lange is associated with 1 patent: “Appliance energy estimation based on voltage sensing.” The invention describes systems and methods that use voltage signals measured at a standard electrical outlet to estimate energy usage by appliances in a home or other location. It can use those measurements to estimate the resistance of a service-drop line wire and the voltage entering the service panel. Together, these values can help determine the current drawn by an operating appliance, without requiring current measurement of the electrical circuit.

Career Highlights

Lange is associated with Amazon Technologies, Inc. His patent focuses on estimating appliance energy consumption using measurements available at ordinary electrical outlets.
