Abstract: The present disclosure relates generally to systems, apparatus, and methods, using non-transitory computer-readable storage media for controlling operation of a health-related device based on physiological data obtained from or about a user. More particularly, the disclosure provides a physiological data-driven control method and apparatus in which biomarker measurements are used to preset and adjust one or more operational characteristics of a therapeutic device during use by the user. In this disclosure, the terms biomarker and biometric are distinguished. Biomarkers are biological, medical indicators (e.g., blood pressure, skin temperature, etc.) used to assess physiological state, condition, or health status, whereas biometrics are unique, measurable physical traits (e.g., fingerprints, facial recognition) used for identification and security.

Abstract: A system for reducing EMF emissions in radiant heating devices comprises paired heating elements, such as halogen infrared tubes or carbon strips, configured to operate with reversed current directions to substantially cancel magnetic field emissions. A conductive shield, fabricated from a metallic material such as aluminum, copper, or stainless steel, is positioned between the heating elements and the user-occupied space and is electrically connected to earth ground to suppress electric field emissions. The combination of magnetic field cancellation through phase-inverted current flow and electric field attenuation via grounded shielding enables the simultaneous reduction of both electric and magnetic field components during normal operation. The system is suitable for use in infrared saunas, space heaters, and other AC- or DC-powered radiant heating applications, and may include control circuitry to manage current phasing, real-time EMF monitoring, and user-selectable EMF mitigation modes.

Abstract: An integrated cold plunge therapy system comprising: a hydro-circulation subsystem with single or multiple pump configurations and directional nozzles; an ice-forming cooling mechanism using thermally conductive coils coupled to a closed-loop refrigeration circuit; a multi-wavelength light therapy subsystem including infrared, red, green, blue, and ultraviolet emitters in waterproof configurations; sound therapy subsystem with liquid-coupled transducers for acoustic stimulation and ice management; and a caster wheel mobility system available in integrated and detachable attachment embodiments. The system is operable via manual or digital controls.
