Patent number: 10670565Abstract: A method and system for inspecting a structure. The method may comprise sending a pulsed wave signal into the structure from a transmitter array. The method may detect a response signal in response to sending the pulsed wave signal into the structure at a group of receivers in a receiver array. The method may identify a group of time delays between sending the pulsed wave signal and may detect the response signal generated in response to the pulsed wave signal at the group of receivers. The method may identify a group of intensities for the response signal detected at the group of receivers. The method may determine a distance to a reflector within the structure using the group of time delays and the group of intensities.Type: GrantFiled: April 12, 2017Date of Patent: June 2, 2020Assignee: The Boeing CompanyInventors: Keith Daniel Humfeld, Scott D.

Patent number: 10487245Abstract: A method of decoupling an adhesive system from a contact surface of an object is disclosed. The adhesive system has a full adhesive strength in a de-energized state. The adhesive system comprises a backing, carbon nanotubes, each having a first end region, coupled to the backing, and a second end region, opposite the first end region, and charged nanoparticles, each coupled to the second end region of at least one of the carbon nanotubes. The method comprises steps of electrically charging the backing and disengaging the adhesive system from the contact surface. Electrically charging the backing creates an electrical repulsion force between the backing and the charged nanoparticles, so that the full adhesive strength of the adhesive system is decreased to a reduced adhesive strength. Disengaging the adhesive system from the contact surface comprises applying a disengagement force to the adhesive system sufficient to overcome the reduced adhesive strength.Type: GrantFiled: January 21, 2019Date of Patent: November 26, 2019Assignee: The Boeing CompanyInventors: Keith Daniel Humfeld, Scott D.
