Publication number: 20240132203Abstract: Systems and methods for fault toleration actuation include an actuator with a position. A first sensor measures a first parameter associated with the actuator. A second sensor measures a second parameter associated with the actuator. A sensor fusion module receives data from each of the first and second sensor and executes a sensor fusion process on the data received to estimate the position of the actuator. A fault detection module is configured to receive data from the first and second sensor, to receive sensor fusion data from the sensor fusion module, to compare the data received from the first and second sensor with the sensor fusion estimate, to identify an error in the data received from either of the first or second sensor based on the comparison, and to determine a fault exists in the first or second sensor based on the error.Type: ApplicationFiled: October 13, 2023Publication date: April 25, 2024Inventors: Ryan MADSON, Meng WANG, Richard Strong WALLACE, JR.

Publication number: 20220332436Abstract: A system and method for testing no-back systems. In one embodiment, the system and method includes multiple actuators that are driven in an asynchronous manner as to impart internal forces that mimic external loads on the system. The actuators can be monitored to determine whether the no-back systems are performing as expected when loads are applied to the actuators.Type: ApplicationFiled: April 15, 2022Publication date: October 20, 2022Inventor: Ryan Madson

Patent number: 10565486Abstract: A transaction card and carrier system. The system includes a panel assembly and transaction card assembly. The transaction card assembly includes a transaction card and one or more snap-off portions selectively detachable from the transaction card along a line of weakness. The transaction card assembly is anchored between at least two panels of the panel assembly along or within a seam or bind area formed by sealing the at least two panels together around or over the snap-off portion. At least one of the panels can further include one or more tamper indicating patterns, such as a starburst pattern. The transaction card assembly is adhered to the one or more tamper indicating patterns such that removal of the card ruptures the pattern.Type: GrantFiled: July 30, 2015Date of Patent: February 18, 2020Assignee: Travel Tags, Inc.Inventors: Shelle B. Pascua, Deborah Bartles, David L. Williams, Ryan Madson, Steven C. Dunn
