Title: Apparatus and method to provide a safe meeting space for face-to-face communication and in-person events
Inventor: DANIEL MICHAEL NORRIS
IPC: E04H3/10
Filed: 2021-09-27
Abstract: The invention provides a safe ‘meeting space’ through which persons can talk to each other normally, without the risk of airborne pathogens passing between them. The meeting space of the invention offers no physical barrier such as glass, which would reduce the quality of communication and diminish the user experience. Persons may see and hear each other through the meeting space but pathogens cannot substantially pass through it. This means users will not be exposed to virus such as coronavirus, covid-19 or SARS or bacterial infection. Various means substantially destroy / inactivate / remove pathogens from the meeting space. For example, solar IR/UV, a convective updraft, airborne antipathogenic agents / ions and/or an electrostatic attractor to remove pathogens. Display means may be incorporated into the meeting space as may sound reflecting components.
