Abstract: With respect to pandemics, restaurants, stadiums, cafeterias, and bars are among the most dangerous places to socialize due to the form of interaction. Exchange of bacteria and viruses are facilitated intensively from the mouth and nose via air transport in droplets of saliva and bodily fluids being deposited on surfaces, foods, and in the air. The present development creates a comfortable environment where the air-space of each customer is separated by invisible cold-hot air and vis-UV barriers, which take away bacteria and viruses, destroying them and preventing recirculation while offering pleasant, clean, and sanitized ambient conditions for a face to face meeting. An immersive experience can be provided with surrounding screens and gas therapy that may be customized according to the customer's preferences. Food distribution is performed with a robotic shuttle system and when the customer departs, an extensive cleanup is performed using chemicals and UV irradiation through robotic systems.

Abstract: COVID-19 is a large virus with remarkable resilience, propagation and multiplication features that require complex technologic systems and manners to assure a reasonable protection. A transparent, multiuse face mask with valves and for inhalation of air from a specialized filter placed in a cleaner air space, and an exhalation valve that drives the exhaled air via a tube to a filter bladder placed on wrist and from there to a tube that has the release end near ground, or can be connected to the aspiration tube of the infrastructure, that removes it, preventing recirculation. The general convention that defines the usage method is that the building, buss, and any other enclosure provide clean antiseptic air above and consumer s have to release their exhalations down near floor from where the structure to remove them by a controlled air flow similar to clean rooms.

Abstract: An electrical transformer system using helical electrodes applied to a plasma. Systems and methods transform DC voltages and currents to different DC voltages and currents. Instead of using wires and iron cores similar to known transformers, the present DC to DC transformer system exploits plasma, helical electrodes, an axial magnetic field and radial magnetic field coils, with a control system to specify a radial magnetic field at the edge of a specified magnitude. A DC input voltage is applied, and an output is taken from electrodes at opposite the ends of the central apparatus. The system and apparatus contains a radial magnetic field embedded in the helical electrodes; the secondary current is taken from either solid or split (slotted) electrodes. Methods are disclosed for changing the output voltage and current relative to the input values. The system can function as either a stepup or a stepdown transformer.

Abstract: An apparatus and corresponding systems and methods for managing electric power, particularly a transformer system and method, and more specifically a transformer for direct current. An example apparatus includes a chamber configured to contain plasma.

At output electrodes extend from the chamber. The output electrodes conduct a second direct current, from the induced motion in the plasma, for delivery from the chamber.

The system includes apparatus which contains a radial magnetic field embedded in the helical electrodes. The system also offers methods for changing the output voltage and current relative to the input values. Thus, the system can function as either a stepup or a stepdown transformer.

Abstract: A tissue sampling apparatus and method obtain a sample of tissue from a selected site and place a hemostatic plug at the selected site. The apparatus includes an external needle and an internal needle within the external needle. A chamber in the internal needle is divided by a divider member into a plug compartment for receiving a hemostatic plug, and a sample compartment for receiving a tissue sample. The divider member is resiliently biased into the plug compartment and the internal needle is movable relative to the external needle for admitting the hemostatic plug into the plug compartment and displacing the divider member into the sample compartment, and then closing the chamber. The apparatus then is advanced to the selected site where relative movement between the internal and external needles opens the chamber, allowing the divider member to expel the hemostatic plug from the plug compartment, and admitting a tissue sample into the sample compartment.

Abstract: A novel set of flexible dialysis tube, needles, tubing and related attachments that may be used to improve the blood sampling, removal, and reinfusion process and reduce the medical hazards of such procedures for the patient. It consists in a special perforation needle over which a plastic tube is passed into the blood vessel, flexible dialysis tube remains inserted and opens gently then bends and morphs to the body structure assuring a good blood flow. A version of flexible dialysis tube may have inside valves and actuators so that bi-directional flow can be obtained following a single vessel puncture instead of two, for procedures such as hemodialysis. An exterior connection box allows a patient to connect to an external blood processing device (hemodialysis) quickly and safely. Further, the device is designed to stay in place for several days or more, further reducing the risks and discomforts of repeated vessel punctures.

Abstract: A method and device to generate electric energy on demand by fusion or transmutation nuclear reactions produced inside a super-capacitor that uses inter-atomic field's particularities obtained inside nano-structures, by using temperature, density and electric fields in order to modify nuclear entanglement and quantum non-localities particularities in order to control nuclear reaction rate of an inserted material, called nuclear fuel, facilitated by the nano-structure nuclear composition, called burner, that controls the non-local nuclear reaction. Fusion or transmutation generated nuclear particles' energy is converted using a super-capacitor made of a micro-nano-hetero structure meta-material that loads from the nuclear energy and discharges by electric current.
