Abstract: In some embodiments, a system for non-destructively testing an object may include a probe. The probe may include a body including a shoe, at least one magnetostrictive sensor assembly supported by the shoe, at least one coupling device of a first type supported by the body, and at least one coupling device of a second type supported by the body. The at least one coupling device of the first type may be configured to provide a first force for coupling the probe to the object. The at least one coupling device of a second type may be configured to provide a second force for coupling the at least one magnetostrictive sensor assembly to the object. In some embodiments, the system may include a pulser/receiver unit configured to be communicatively coupled to the at least one magnetostrictive sensor assembly.

Abstract: The present disclosure is directed to a system for calibrating cameras with a fixed focal point. In particular, a camera calibration system comprising one or more computing devices can project a plurality of fiducial markers on a target surface using the plurality of collimators. The camera calibration system can capture, using the camera, a plurality of images of the target surface with the camera, wherein the camera is rotated between each captured image in the plurality of images. The camera calibration system can compare the plurality of images with a ground truth projection. The camera calibration system can generate calibration data based on the comparison of the plurality of images with the ground truth projection. The camera calibration system can store the calibration data for use in rectifying the camera.

Abstract: Systems and methods for applying signals, including contralesional electromagnetic signals, to neural populations, are disclosed. A particular method can be directed to treating a patient having a subject neural population in a first (e.g., ipsilesional) hemisphere of the brain, with the subject neural population having, or previously having, a functionality capable of being improved. The method can include directing an application of electromagnetic signals at least proximate to a target neural population at a second (e.g., contralesional) hemisphere of the brain to at least constrain a functionality of the target neural population, which has transcallosal communication with the first hemisphere.

Abstract: Electromagnetic signal delivery for tissue affected by neuronal dysfunction, degradation, damage, and/or necrosis, and associated systems and methods are disclosed. A method in accordance with one embodiment of the invention includes identifying an affected region, with the affected region including neuronal tissue that, at least during a pre-dysfunctional period, was in neural communication with neuronal tissue in a dysfunctional region. The affected tissue can be functionally adversely affected by neuronal dysfunction in the dysfunctional region. The method can further include applying electromagnetic signals to the neuronal tissue in the affected region. For example, the electromagnetic signals can be applied to a hypo-active neural region that is not physically damaged, and has been identified as likely to recover at least in part as a result of electromagnetic signals. Signals can be applied at sub-threshold levels to cortical and/or subcortical regions.
