    Abstract: A cooling system for a subterranean power line may include a cooling tube configured to house a fluid. Heat generated by the subterranean power line may be radiated and/or conducted to the cooling tube and absorbed by the fluid within the cooling tube. As the fluid heats up, it may change phase from a liquid to a gas. The hot gas may rise to a heat-exchanging condenser configured to dissipate the heat and condense the fluid back into a liquid. The cool, condensed liquid my return from the heat-exchanging condenser to the cooling tube. Risers, gas transport tubes, pressure regulation systems, fluid storage tanks, and other components described herein may increase the efficiency of the cooling system and/or otherwise improve the viability of the cooling system for subterranean power lines.

    Abstract: An active torso support includes multiple force applying elements for applying force to selected regions of a torso of a subject, to reduce or prevent injury or discomfort, under the control of control circuitry on the torso support. Target regions for application of force are selected by detecting the position of a landmark in or on the torso of the subject relative to a portion of the torso support, and selecting one or more force applying elements closest to the target region. Force can be applied according to spatial or temporal patterns, selected in response to user input or detected motion or activity of the subject. Related devices and methods are described.

    Abstract: Described embodiments include a system, device and method. A described device includes a layer of a first material configured to reflect a substantial portion of a specified incident air blast wave energy. The layer of the first material has an acoustic impedance substantially mismatched to air's acoustic impedance, and a thickness less than about 3 mm. The device includes a layer of a second material configured to attenuate a substantial portion of the specified incident air blast wave energy utilizing an inelastic response. At least a portion of a back surface of the first material is proximate to at least a portion of a front surface of the second material.
