Abstract: A method performed by a computing system comprises receiving shape information for an elongate flexible portion of a medical instrument. The medical instrument includes a reference portion movably coupled to a fixture having a known pose in a surgical reference frame. The fixture includes a constraint structure having a known constraint structure location in the surgical reference frame. The elongate flexible portion is coupled to the reference portion and is sized to pass through the constraint structure. The method further includes receiving reference portion position information in the surgical reference frame; determining an estimated constraint structure location in the surgical reference frame from the reference portion position information and the shape information; determining a correction factor by comparing the estimated constraint structure location to the known constraint structure location; and modifying the shape information based upon the correction factor.

Abstract: A system includes a control means for receiving an input from a user, a manipulator means configured to support a tool having a tool frame, and processing means configured to perform a method. The method involves receiving, from an image capturing system with an image frame, one or more images. The tool is visible in the one or more images. The method further involves determining an estimated frame transform based on the one or more images. The estimated frame transform is used in defining an unknown frame transform between the image frame and the tool frame. The method also involves determining, in response to the input received at the control means, an output movement for the tool based on the estimated frame transform, and causing movement of the tool based on the output movement.

Abstract: A speaker comprises a housing, a transducer residing inside the housing, and at least one sound guiding hole located on the housing. The transducer generates vibrations. The vibrations produce a sound wave inside the housing and cause a leaked sound wave spreading outside the housing from a portion of the housing. The at least one sound guiding hole guides the sound wave inside the housing through the at least one sound guiding hole to an outside of the housing. The guided sound wave interferes with the leaked sound wave in a target region. The interference at a specific frequency relates to a distance between the at least one sound guiding hole and the portion of the housing.
