Abstract: An airbag deployment system includes a helmet, a torso protection assembly, and an airbag assembly. The airbag assembly is coupled to one of the helmet and the torso protection assembly and includes an airbag, an inflation device configured to inflate the airbag, and a first coupling device. The first coupling device is configured to couple to a second coupling device provided on the other of the helmet and the torso protection assembly upon inflation of the airbag. The coupling resists relative movement between the helmet and the torso protection assembly.

Abstract: A composite medium may be artificially structured to enhance electron-phonon coupling in the composite medium, whereby to enhance a Cooper pairing instability in the composite medium. This yields a composite superconductor with superconducting properties (energy gap, critical temperature, etc.) more robust than the superconducting properties of the constituent media. The electron-phonon coupling may be enhanced by increasing the phononic density of states in the composite medium, by introducing hyperbolic phononic dispersion, phononic van Hove singularities, and/or reduced phonon group velocities.
