Abstract: This document describes medical systems that use artificial intelligence to facilitate autonomous or semi-autonomous medical procedures. For example, this document describes heart/lung machine systems that are used in conjunction with artificial intelligence systems to facilitate autonomous or semi-autonomous open-heart surgery operations.

Abstract: A method is provided for making a tubing, which includes forming a generally tubular inner layer by flowing a first material through an extrusion assembly. At least one non-tubular segment is formed along the length of the tubing by flowing a second material through the extrusion assembly. A generally tubular outer layer coaxial with the inner layer is formed by flowing a third material through the extrusion assembly. The segment is positioned between the inner and outer layers and oriented non-tangentially with an interface between the inner and outer layers. The resulting tubing, which may be suitable for medical applications, may have kink-resistant properties.

Abstract: A flexible, kink-resistant medical tube and a method and apparatus for making the same are provided. The tube includes a body having a first end, a second end, an outer surface and an inner surface. The tube includes a lumen defined by the inner surface of the body and extending between the first end and the second end. The tube also includes a helical structure within in the body.

Abstract: A radio-frequency-device test range (the Refractive Compact Range) includes a physical space having a source zone for placing an antenna or array of antennas, and a test zone for placing a sensor or other device to be tested. A lens and an apodizer are placed in the physical space between the source zone and the test zone. The lens serves to collimate radiated energy emanating from the antenna toward the test zone. The lens may have a surface treatment, such as an anti-reflective coating or a surface pattern, on one or both surfaces. The apodizer functions to keep energy from diffracting off the edge of the lens and getting into the field of view (the test zone). The sensor or other device to be tested may be placed on a moveable mount to allow it to be moved, to simulate relative movement of the device and a radio frequency source, such as radiated by an antenna.
