Abstract: Devices, systems, and methods for imaging and measuring deflections in structures such as railroad rail are disclosed. One exemplary embodiment relates to a vision system having a high-speed, visible-light imaging camera and an evaluation unit configured for analyzing images from the camera to detect geometric variations in the structure. In a second example, additional sensors are used to identify the wheel location(s) in the same reference frame as the measurement system. In analyzing structures such as railroad track rail, the imaging camera can be coupled to a moving rail vehicle and configured for generating images of the rail as the vehicle moves along the track.

Abstract: The embodiments disclosed herein relate to various systems and methods for determining the residual stress in polycrystalline materials.

Abstract: The various embodiments herein relate to systems, devices, and/or methods relating to surgical procedures, and more specifically for accessing an insufflated cavity of a patient and/or positioning surgical systems or devices into the cavity.

Abstract: The embodiments disclosed herein relate to various medical device components, including components that can be incorporated into robotic and/or in vivo medical devices. Certain embodiments include various medical devices for in vivo medical procedures.

Abstract: The various embodiments disclosed herein relate to various robotic medical devices, including robotic devices that are disposed within a body cavity and positioned using a support component disposed through an orifice or opening in the body cavity. Additional embodiments relate to devices having arms coupled to a device body wherein the device has a minimal profile such that the device can be easily inserted through smaller incisions in comparison to other devices without such a small profile. Further embodiments relate to methods of operating the above devices.

Abstract: Apparatuses for guiding an endotracheal tube during intubation and associated methods of their use; the apparatuses formed to contain a plastic element able to hold deformations so as to conform the apparatus to the shape of a patient's endotracheal airway. The plastic element has sufficient give so as to minimize traumatic engagement with the inner surface of the airway lumen. Methods for using the apparatuses exploit indirect visualization where the person performing the intubation can shape the apparatuses so as to place the distal end into the field of view of the indirect visualization instrument even with minimal alignment of the patient's airway.
