Patent number: 10201278Abstract: Systems and methods for detecting biometrics using a life detecting radar are disclosed. Life detecting radars can include transmit antennas configured to transmit continuous microwave (“CW”) radio signals that reflect back upon making contact with various objects. The signal can be systematically varied in frequency to provide a signal that is essentially continuous with short gaps between transmissions at different frequencies. The reflected return signals are received by one or more receive antennas and processed to detect one or more targets. The received signal can include a static (i.e. constant phase) signal corresponding to reflections from objects that do not move. The received signal can also include a phase varying signal that corresponds to reflections from a living target having measurable biometrics including (but not limited to) breathing patterns and heartbeats. Clutter can be removed and the remaining portions of the received signal are analyzed for target detection.Type: GrantFiled: April 18, 2014Date of Patent: February 12, 2019Assignee: California Institute of TechnologyInventors: James Paul Lux, Vaughn P. Cable, Salman-ul Mohammed Haque, Michael Ray McKee, Hirad Ghaemi, Richard Kalantar Ohanian

Patent number: 9986934Abstract: Systems and methods for detecting biometrics using microwave radar sensor modules are disclosed. Integrated microwave sensor modules can include a transmitter unit configured to generate at least one continuous wave transmit signal based upon at least one frequency control signal, a receiver unit configured to utilize a cancellation path to cancel contributions to a return signal based upon at least one cancellation path control signal, and a microcontroller unit that includes a processor, a memory containing a microcontroller application, where the microcontroller application configures the processor to generate at least one frequency control signal to generate least one CW transmit signal having a plurality of frequencies, generate at least one cancellation path control signal to automatically adjust the cancellation path in real time, receive at least one demodulated signal, digitize the at least one demodulated signal, and update the at least one frequency control and cancellation path control signals.Type: GrantFiled: January 29, 2015Date of Patent: June 5, 2018Assignee: California Institute of TechnologyInventors: James Paul Lux, Richard Kalantar Ohanian, Raymond Quintero, Troy Michael Torrez, Keizo Ishikawa, Michael Ray McKee, Salman-ul Mohammed Haque, Sarah Holmes, Carl Spurgers

Patent number: 9870457Abstract: Systems and methods for identifying and/or authenticating individuals utilizing microwave sensing modules are disclosed. A HEaRtbeat Microwave Authentication (HERMA) system can enable the active identification and/or authentication of a user by analyzing reflected RF signals that contain a person's unique characteristics related to their heartbeats. An illumination signal is transmitted towards a person where a reflected signal captures the motion of the skin and tissue (i.e. displacement) due to the person's heartbeats. The HERMA system can utilize existing transmitters in a mobile device (e.g. Wi-Fi, Bluetooth, Cellphone signals) as the illumination source with at least one external receive antenna. The received reflected signals can be pre-processed and analyzed to identify and/or authenticate a user.Type: GrantFiled: August 17, 2015Date of Patent: January 16, 2018Assignee: California Institute of TechnologyInventors: James Paul Lux, Edward Chow, Michael Ray McKee, Salman-ul Mohammed Haque, Andre Tkacenko
