Patent number: 9989553Abstract: Systems and methods are described herein for extracting inertial information from nonlinear periodic signals. A system for determining an inertial parameter can include circuitry configured for receiving first and second analog signals from first and second sensors, each sensor responsive to motion of a proof mass. The system can include circuitry configured for determining a difference between the first and second analog signals, determining a plurality of timestamps corresponding to times at which the difference crosses a threshold, and determining a plurality of time intervals based on the timestamp. The system can include circuitry configured for determining a result of applying a trigonometric function to a quantity, the quantity based on the plurality of time intervals and determining the inertial parameter based on the result.Type: GrantFiled: May 20, 2016Date of Patent: June 5, 2018Assignee: Lumedyne Technologies IncorporatedInventors: Richard Lee Waters, Mark Steven Fralick, Charles Harold Tally, IV, John David Jacobs

Patent number: 9910061Abstract: Systems and methods are disclosed herein for extracting system parameters from nonlinear periodic signals from sensors. A sensor such as an inertial device includes a first structure and a second structure that is springedly coupled to the first structure. The sensor is configured to generate an output voltage based on a current between the first and second structures. Monotonic motion of the second structure relative to the first structure causes a reversal in direction of the current.Type: GrantFiled: June 26, 2015Date of Patent: March 6, 2018Assignee: Lumedyne Technologies IncorporatedInventors: Richard Lee Waters, John David Jacobs, Charles Harold Tally, IV, Xiaojun Huang, Yanting Zhang, Mark Steven Fralick

Publication number: 20170003314Abstract: Sensors and systems are described herein for out-of-plane sensing. In particular, the sensors and systems relate to vibratory inertial sensors implementing time-domain sensing techniques with linear combinations of multiple signals. In out-of-plane sensing, these multiple signals may be produced from a single sense mass oscillation. Time intervals produced from linear combinations of these multiple signals can be used to measure inertial parameters, such as acceleration, and other values of interest.Type: ApplicationFiled: June 30, 2016Publication date: January 5, 2017Inventors: Richard Lee Waters, Charles Harold Tally, IV, Xiaojun Huang, John David Jacobs, Yanting Zhang, Mark Steven Fralick
