Abstract: Two portable disinfection systems for indoor air disinfection are provided. One system is designed to be equipped with an external Far-UVC lamp as UV source, while the other is designed to be equipped with an internal Far-UVC tubular lamp as UV source. The system's portability makes it versatile and applicable in many different scenarios. The portability of these systems makes them versatile and suitable for various scenarios, including room disinfection and public transportation. They can function as standalone air disinfection units or be integrated with existing technologies to further reduce airborne pathogen concentrations.

Abstract: A method for recovering lithium from a lithium-containing solution is provided. A lithium-containing solution with an adjusted pH value or an unadjusted pH value is mixed with a meta-aluminate, and the pH value is adjusted to weak acid/neutral, so that lithium can be separated from the lithium-containing solution in the form of a precipitate of LiaX·2Al(OH)3·nH2O. Then, the precipitate is converted into a lithium adsorbent of (1-m)LiaX·2Al(OH)3·nH2O and a LiaX-containing filtrate through desorption of lithium. High-purity Li2CO3 is obtained by performing precipitation of lithium on the LiaX-containing filtrate.

Abstract: A lithium ion adsorbent includes a material having a chemical formula of LiCl.2Al(OH)3.nH2O. n is an integer from 1 to 3, a specific surface area of the lithium ion adsorbent is 20-36 m2/g, an average pore diameter of the lithium ion adsorbent is 20-35 nm, a total pore volume of the lithium ion adsorbent is 0.15-0.32 mL/g, a D10 of the lithium ion adsorbent is 3-12 ?m, a D50 of the lithium ion adsorbent is 12-22 ?m, and a D90 of the lithium ion adsorbent is 20-40 ?m.

Abstract: An online system receives information describing events corresponding to actions associated with a third party system performed by an individual. The received information describes event types and times at which the events occurred. The online system generates nodes of a directed graph associated with the third party system, in which each node corresponds to an event type. For each event, a node count associated with a node corresponding to the event's type is incremented by the online system. Pairs of consecutively occurring events are identified based on times at which the events occurred and an edge describing each transition from one event to another is generated by the online system. The online system determines an edge count for each transition indicating a number of edges describing the transition as well as a sequential order of event types based on one or more node counts and one or more edge counts.

Abstract: The present disclosure discloses a method, apparatus, and system for sharing a virtual reality (VR) viewport.

Abstract: The present invention discloses a networked communication system. The networked communication system comprises a multipoint control unit (MCU) operating a MCU server to receive and process multimedia data transmitted from a plurality of networked communication devices functioning as clients of the MCU. The multimedia data transmitted from each of the clients further include meta-data identifying each of the clients transmitting the multimedia data and the MCU server further processes the multimedia data according to the meta-data to position the multimedia data in a plurality of frames for real-time multiple party display for each of the clients.

Abstract: A video player instance may be prioritized and decoding and rendering resources may be assigned to the video player instance accordingly. A video player instance may request use of a resource combination. Based on a determined priority a resource combination may be assigned to the video player instance. A resource combination may be reassigned to another video player instance upon detection that the previously assigned resource combination is no longer actively in use.

Abstract: Disclosed is a method for video monitoring based on Universal Plug and Play (UPnP), comprising the steps of: a camera device saves an improved Digital Media Server (DMS) function; after receiving the request transmitted by a Digital Media Control (DMC) device, for obtaining the video stream, the camera device analyzes the request for obtaining video stream by the improved DMS function and then starts camera shooting. Also disclosed is a device and system for video monitoring based on UPnP. The present invention can provide function of real-time video monitoring in the UPnP network architecture.
