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.

An internet-of-things (IOT) robotic sterilization system that operates autonomously for use in the prevention of diseases, e.g., Coronavirus Disease 2019 (COVID-19), caused by pathogens such as coronavirus SARS-CoV-2 and other pathogens present within an interior space is described. A robotic sterilization device is communicatively coupled to the IOT base module via an IOT network, and includes a misting or fogging system fluidically coupled to a liquid reservoir, a sensor module including plurality of sensors, a controller, and a locomotion system. The robotic sterilization device navigates a path within the interior space while creating a disinfecting mist with the misting system, and may coordinate with other IOT-connected devices, such as the HVAC system, UV Vent sterilizers, scent dispensing appliances, and others to more efficaciously sanitize the interior space to protect humans by eliminating pathogens.

An omni-bearing intelligent nursing system and method for a high-infectious isolation ward, including: a nursing robot, including a robot body and a controller; a plurality of collectors, arranged in the isolation ward and used for detecting the physiological index of the user and transmitting the physiological index to a remote control system; a communication network, in a star topology structure and including a plurality of communication modules, and configured to realize the communication of each the nursing robot, the collector and the remote control system; and the remote control system, receiving the information of the collector, performing feature extraction on the collect multi-element physiological signals, combining the basic information of the user, perform learning by a decision tree model, dynamically adjusting the corresponding nursing level, and sending an instruction to the corresponding nursing robot.

A flow control system for three-dimensional (3D) control of fluids with a high spatiotemporal resolution using alternating magnetic fields is disclosed. This technology is applicable to many disciplines, including fluid dynamics, microfluidics, electrochemistry, metallurgy, and healthcare. In particular, the proposed technique can address challenging problems such as turbulence control, drag reduction, contactless mixing, crystal growth control, and targeted drug delivery.
