Abstract: The present disclosure relates to the technical field of wastewater treatment, and provides a wastewater treatment method and apparatus based on hydrate-based water vapor adsorption. The apparatus includes a wastewater evaporation zone, a hydrate formation zone, a hydrate decomposition zone, and a data acquisition and control system. Rising water vapor and condensed water formed during evaporation of wastewater at normal temperature react with a hydrate former on a cooling wall surface to form a hydrate, continuous evaporation of the wastewater is promoted, the hydrate is scraped off to a collecting zone below by a scraper after being formed, and the hydrate is decomposed into fresh water, thereby realizing wastewater treatment. The present disclosure provides a method for treating complex wastewater containing a plurality of pollutants, where water vapor is consumed to form the hydrate to promote wastewater evaporation, and water obtained from the decomposition does not contain pollutants theoretically.

Abstract: Multi-player co-located AR experiences are augmented by assigning characters and costumes to respective participants (a.k.a. “users” of AR-enabled mobile devices) in multi-player AR sessions for storytelling, play acting, and the like. Body tracking technology and augmented reality (AR) software are used to decorate the bodies of the co-located participants with virtual costumes within the context of the multi-player co-located AR experiences. Tracked bodies are distinguished to determine which body belongs to which user and hence which virtual costume belongs to which tracked body so that corresponding costumes may be assigned for display in augmented reality. A host-guest mechanism is used for networked assignment of characters and corresponding costumes in the co-located multi-player AR session. Body tracking technology is used to move the costume with the body as movement of the assigned body is detected.

The following interface includes methods for selecting objects and instructions for connecting a virtual object to a target object. In one example, the recording application presents on the display a virtual tether between the objects until a connecting action is detected. The following interface is presented on the display as an overlay, in the foreground relative to the physical environment.

Abstract: A virtual interface application presented in augmented reality (AR) is described for controlling Internet of Things (IoT) products. The virtual interface application enables a user of a portable electronic device to activate a virtual control interface overlay on a display, receive a selection from the user using her hands or feet, and send a control signal to a nearby IoT product which executes an action in accordance with the selection. The virtual control interface is presented on the display as a virtual object in an AR environment. The virtual interface application includes a foot tracking tool for detecting an intersection between the foot location (in the physical environment) and the virtual surface position (in the AR environment). When an intersection is detected, the virtual interface application sends a control signal with instructions to the IoT product.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) and a network entity may utilize multi-port mobility reference signals to assist with spatial based mobility procedures. The UE may receive a reference signal that is associated with multiple antenna ports. The UE may measure a multi-dimensional channel response based on the reference signal. The multi-dimensional channel response may be associated with measured channel metrics corresponding to the multiple antenna ports. The UE may transmit a report that includes a channel measurement vector based on the multi-dimensional channel response. The channel measurement vector may indicate multiple measured channel metrics for one or more dimensions of the multi-dimensional channel response. The network entity may transmit a message that indicates one or more metrics associated with mobility management for the UE based on the report that indicates the channel measurement vector.

Abstract: A method for detecting full-body gestures by a mobile device includes a host mobile device detecting the tracked body of a co-located participant in a multi-party session. When the participant's tracked body provides a full-body gesture, the host's mobile device recognizes that there is a tracked body providing a full-body gesture. The host mobile device iterates through the list of participants in the multi-party session and finds the closest participant mobile device with respect to the screen-space position of the head of the gesturing participant. The host mobile device then obtains the user ID of the closest participant mobile device and broadcasts the recognized full-body gesture event to all co-located participants in the multi-party session, along with the obtained user ID. Each participant's mobile device may then handle the gesture event as appropriate for the multi-party session. For example, a character or costume may be assigned to a gesturing participant.

The virtual rotational interface is presented on the display as a virtual object in an AR environment. The IMU control application detects the device orientation (in the physical environment) and in response presents a corresponding slider element on the virtual rotational interface (in the AR environment).

Abstract: Embodiments of the present disclosure relate to methods and apparatuses of transmitting information and receiving information in a wireless communication system. In the method of transmitting information, the information comprises at least two of a reference signal and more than one radio resource control (RRC) message.
