  • Patent number: 11406726
    Abstract: The disclosed Multi-function Germicidal Apparatus and Method, is an elevation actuator equipped mobile floor-standing air convection system including an electromagnetic radiation oscillating head mounted dish with zoom and focusable UV beam projectors which sweep across a horizontal plane to inactivate airborne pathogens. An open end germicidal chamber behind an open center nozzle is equipped with multi-wavelength UV lights to inactivate passing pathogens and irradiate TIO2 coated charge plates to generate hydroxyl radicals. A fan pushes contaminated air through a chamber discharging remnant pathogens and air mixed through a nozzle to create a high velocity air mixture farther away from the opening. An oscillating and focused UV beam forms a tubular shaped virtual cage encircling exiting pathogens for continuous inactivation. Convection forced pathogens disperse to the floor are picked up by a floor fan and sent back to a chamber and UV beams for repeating inactivation.

  • Publication number: 20210299311
    Abstract: An autonomous drone operated remotely via wireless networks is instructed by its owner flying about in an unoccupied room to activate a system of selectable air and surface disinfection modules. An air purifier captures particles in ambient air and switches on an oscillating motion tubular shaped cage mounted with a plurality of Ultraviolet C spectrum, long range zoom and focusable lens LED projectors to disinfect virus and bacteria. A fan assisted forced air Ozone generator module speeds up disinfecting inconspicuous spots to destroy hidden viruses. Disinfection is completed after the half-life time of dispensed Ozone and an oxygen recovery module rapidly converts residual ozone still in air back to normal oxygen molecules enabling a shortened waiting time for occupants to return to the treated room. A negative ions module subsequently switches on to refresh the air.

  • Patent number: 10589116
    Abstract: A wearable pain management apparatus includes a drum shaped oscillatory motion driver mounted with electromagnetic coils attached to a non-stretching belt tightly strapped around a user's waist. The driver's top surface is pressed against the back of the user's waist. A belt has a ratchet buckle and a group of elongated tracks. A holster with a battery pack is securely clipped onto the belt. A center mounted motor drives a set of torque conversion planetary gears. An off center mounted mass rotates and causes unbalance and an oscillatory motion. A power cable laminated between two surfaces of the belt body terminates on a switch. The user holds a deep breath while pulling hard on the belt end causing the ratchet buckle to lock on the tracks. This action effectively places hand pressure on the apparatus rubbing on their back via the Oscillatory Pulsed Electromagnetic Field to speedily alleviate pain.

  • Patent number: 10501180
    Abstract: A first drone equipped with a high energy Directional Ultrasound Parametric Speaker Array and a second drone equipped with an Acoustic Dispersion Cannon are used to fight wildfire. The first drone is distanced far from a burning flame but in close proximity to a fire target. Both drones are guided by GPS to communicate with remote operators. Once the target is locked, the first drone blasts the target with Amplitude Modulated Ultrasound. The Ultrasound is self-demodulated into a lower frequency audio sound when it encounters a hot flame of richly charged ions. The lowered frequency sound pushes and pulls the flame forward and backward rapidly away from the combustion source, causing it to be disconnected from the flame which instantly cools down and is extinguished. The second drone blasts the combustible source with powerful sonic shockwaves to disperse the still hot particulates further apart to prevent the source being reignited.

  • Publication number: 20180235044
    Abstract: A multi-group brightness controllable LED tube comprises a multi-input source selector which directs electric power to the tube from a set of diversion switches inserted between a power source and preexisting ballast. The diversion switches automatically re-establish new electric current paths to supply the LED tube power and safely bypass the preexisting ballast. The LED tube also comprises a digital sub section selector for selecting two groups of SMD (surface mounted device) LED strip lights for intensity control. When first turned on, the light will be at 66% brightness. A first toggle action dims the light to 33% brightness, and a second toggle action brings it up to 100%. The third toggle will reset the LED tube to 66% brightness. The retrofitted LED tube is suitable for single end as well as double end fixtures without a complicated conversion process. Furthermore, fixtures can be reverted back to original fluorescent operation.

  • Patent number: 9999213
    Abstract: An autonomous drone integrated with wide bandwidth, high energy acoustic wave generators sent to evict and eradicate agricultural pests within a patrolling area. The drone hovering close to a plant bombards its leaves and fruits with high energy acoustic waves via frequency and tone determined by an onboard synthesizer through acoustic power amplified to drive the sideways and bottom mounted acoustic wave generators. Agricultural pests such as caterpillar, beetle and the like are bombarded with powerful acoustic waves causing their bodies to vigorously vibrate and resonate with synthesizer frequency to dislodge or kill the pests. Other insects such as moths are forced airborne by a propeller's strong downdraft and are electrocuted by integrated high voltage screens. Inside a hotel room, the drone hovers close to a surface of a bedding mattress, bombarding the surfaces with powerful acoustic waves tuned to frequencies that cause bed bugs to resonate and die.

  • Patent number: 9807996
    Abstract: A drone with a high-voltage trap seeks, identifies, pursues and destroys flying insects within a patrolling area. During its passive attracting mode, the drone lands on a designated ground site and attracts insects with light, sound, and scents. Once insects are lured, the high voltage screens trap will immediately electrocute targeted insects. In its active offensive mode, the drone hovers closer to insect nests using its high-velocity propellers, producing strong downdraft jet streams to disturb the nest and force insects, such as mosquitoes and the like, to evacuate their nest. Once insects are airborne, the drone pursues fleeing insects from below or behind, making use of its propellers and vacuuming the fleeing insects. Slow flying insects that come in contact with the high-voltage electrified screens are immediately electrocuted. Insects that are vacuumed into the fast-spinning propellers blades are knocked down and killed. A rectified charging pad recharges the drone batteries.
