Patent number: 11163105Abstract: A sensor system includes an optical fiber. A set of wavelength shift sensors are inscribed on the optical fiber. The set includes at least one first wavelength shift sensor configured to reflect a first wavelength band of input light as a first optical output signal. The first wavelength shift sensor has a first value of an optical characteristic that modifies intensity of the first optical output signal. At least one second wavelength shift sensor is configured to reflect a second wavelength band of input light as a second optical output signal. The second wavelength shift sensor has a second value of the optical characteristic that modifies intensity of the second optical output signal, wherein the second value is different from the first value.Type: GrantFiled: December 28, 2020Date of Patent: November 2, 2021Assignee: Palo Alto Research Center IncorporatedInventors: Kyle Arakaki, Peter Kiesel, Ajay Raghavan

Patent number: 10330734Abstract: A system detects and/or predicts metal ion plating events of a metal ion energy storage device. The system includes an optical sensor disposed internally within or externally on a metal ion energy storage device wherein the optical sensor has an optical output that changes in response to strain within a metal ion energy storage device. A current sensor senses current through the metal ion energy storage device. Plating detection circuitry measures a wavelength shift in the optical output of the optical sensor and estimates a state of charge (SOC) of the metal ion energy storage device based on the current. An expected wavelength shift is determined from the estimated SOC. A plating event can be detected and/or predicted based on the difference between the expected wavelength shift and the measured wavelength shift.Type: GrantFiled: July 18, 2017Date of Patent: June 25, 2019Assignee: Palo Alto Research Center IncorporatedInventors: Bhaskar Saha, Anurag Ganguli, Ajay Raghavan, Peter Kiesel, Kyle Arakaki, Julian Schwartz

Patent number: 10317256Abstract: A monitoring system includes optical sensors disposed on one or more fiber optic waveguides. Each optical sensor is spaced apart from other optical sensors and is disposed at a location along a route defined by a transportation structure that supports a moveable conveyance. The plurality of optical sensors are mechanically coupled to one or both of the transportation structure and the moveable conveyance. Each optical sensor provides an optical output signal responsive to vibrational emissions of one or both of the transportation structure and the conveyance. The monitoring system includes a detector unit configured to convert optical output signals from the optical sensors to electrical signals. A data acquisition controller synchronizes recordation of the electrical signals with movement of the conveyance.Type: GrantFiled: April 14, 2017Date of Patent: June 11, 2019Assignee: Palo Alto Research Center IncorporatedInventors: Ajay Raghavan, Kyle Arakaki, Andreas Schuh, Alex Hegyi, Peter Kiesel, Anurag Ganguli
