Abstract: The present disclosure provides devices and systems for prevention from air born viruses, bacteria or contaminants, in particular, the device acts as an air shield that is placed on the human forehead and generates a differential high pressure in front of the human face that blocks the viruses from reaching the face. The device is composed of air fans with controlled speeds, air filters, an air cone, an air slot, and controlled circuitry to operate the device.

Abstract: The present disclosure is directed to systems, device and methods for cancer ablation treatment of human and animal subjects through the application of a combination of electromagnetic sources, in particular, microwave and radio frequency radiation that are focused on a tumor harboring magnetic or other metallic nanoparticles to result in synergetic heating effect whereby the tumor is heated to ablative temperature due to the strong absorption of the nanoparticles while the surrounding healthy tissue is hardly affected.

Abstract: The present disclosure provides devices, systems and methods for hyperthermia cancer treatment by supplying ferromagnetic nanoparticles to a target area having or suspected of having cancer cells, the ferromagnetic nanoparticles are configured to attach to the cancer cells and heat by absorbing magnetic energy, and radiating the target area with microwaves such that the target area is within a nearfield range of the radiated microwave, and the microwave radiation nearfield is magnetically biased such that the ratio of magnetic energy to electric energy is greater than 1.
