    "goal": "Remote, non-lethal incapacitation of humans by inducing disorientation, motion sickness and vomiting.",
    "problem_addressed": "Need for a stun weapon that can incapacitate hostile individuals through walls without causing permanent injury.",
    "concept_summary": "A handheld or portable system that emits a directed radio-frequency (RF) beam. The beam creates Lorentz forces on ionic currents in the vestibular hair cells and other sensory nerves, disrupting mechanical transduction and chemical processes, leading to loss of balance, severe motion sickness and vomiting.",
