Abstract: The present invention relates to apparatuses, systems, and methods that manage the flow of fluids, such as, for example, water, through pipes. Specifically, the apparatuses of the present invention creates a backward pressure in fluid traversing a pipe when the fluid meets a spring loaded poppet valve, wherein the backward pressure within the pipe provides compression to the fluid effectively compressing entrapped gas bubbles within the fluid. The pressure in front of the poppet valve builds and moves the poppet valve away from a seat allowing the fluid with compressed gas bubbles to flow therefrom, which provides more accurate water meter measurements because less gas is being considered in said measurements. Moreover, the apparatuses of the present invention provide backflow prevention. Systems and methods for managing fluids are further provided.

Abstract: Example implementations may relate to methods and systems for detecting an event in a physical region within a physical space. Accordingly, a computing system may receive from a subscriber device an indication of a virtual region within a virtual representation of the physical space such that the virtual region corresponds to the physical region. The system may also receive from the subscriber a trigger condition associated with the virtual region, where the trigger condition corresponds to a particular physical change in the physical region. The system may also receive sensor data from sensors in the physical space and a portion of the sensor data may be associated with the physical region. Based on the sensor data, the system may detect an event in the physical region that satisfies the trigger condition and may responsively provide to the subscriber a notification that indicates that the trigger condition has been satisfied.

Abstract: A system includes a processor and a memory. The memory stores instructions that, when executed by the processor, cause the processor to perform operations including sending a primary multicast video stream and a secondary multicast video stream to a media device. The secondary multicast video stream is limited to intra-coded frames (I-frames) extracted from the primary multicast video stream. Transmission of each intra-coded frame (I-frame) of the secondary multicast video stream is delayed with respect to transmission of a corresponding I-frame of the primary multicast video stream. The delay is based on an amount of writing time to satisfy a buffer threshold of a video content buffer at the media device to prevent a noticeable time shift of video displayed by the media device when the media device switches from outputting the secondary multicast video stream to outputting the primary multicast video stream.
