Abstract: A water outlet box of a pressure-type flushing system and a toilet using the water outlet box, including a water outlet box main body and a first one-way valve assembly. The water outlet box main body is formed with a water-passing cavity, a water inlet, at least one water outlet and a vent, with the water inlet, the water outlet and the vent all connecting with the water-passing cavity. The first one-way valve assembly is provided opposite to the water inlet to open or block the water inlet, and when the pressure-type flushing system finishes flushing, the first one-way valve assembly blocks the water inlet. The vent is provided at the top of the water-passing cavity and is open to the atmosphere. The water outlet box main body is provided with several water inlet pipes in communication with the functional devices of the pressure-type flushing system.

Abstract: The present application provides a displaying base plate and a displaying device, which relates to the technical field of displaying. The displaying device can ameliorate the problem of screen greening caused by electrostatic charges, thereby improving the effect of displaying. The displaying base plate includes an active area and a non-active area connected to the active area, the non-active area includes an edge region and a first-dam region, and the first-dam region is located between the active area and the edge region; the displaying base plate further includes: a substrate; an anti-static layer disposed on the substrate, wherein the anti-static layer is located at least within the edge region; and a driving unit and a touch unit that are disposed on the substrate, wherein the driving unit is located within the active area.

Abstract: A system for creating virtual environments for virtual events is disclosed. The system allows the user to create any event in a virtual environment. The system comprises a computing device, a database in communication with the computing device, and one or more user devices with camera in communication with the computing device. The computing device comprises a processor and a memory in communication with the processor, wherein the memory stores a set of instructions executable by the processor. The user devices communicate the computing device via a network using an application software or mobile application or web-based application executed in a computer-implemented environment or network environment. Each user device is configured to create and/or access the virtual events. The computing device is configured to communicate one or more virtual attendees present in their physical location and virtually put the attendees in their virtual space in the virtual event.

Abstract: A user and test sample authentication system and method for identifying COVID-19 infected users is disclosed. An authentication platform receives a first user profile data from a first user device to register to an authentication service and generate a first scannable image. The platform receives a second user profile data from the second user device for registration and generates a second scannable image. A purchase order of a medical kit is placed to perform one or more diagnosis procedures on the first user to identify if the first user is infected by COVID-19. The diagnosis data is encoded to the first scannable image to form a unique corona ID. On scanning the unique ID, the diagnosis data and the user profile data are displayed, whereby the presence of coronavirus infection of the first user is determined before contacting one or more individuals to prevent spread of the disease or infection.
