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 method of disseminating information includes detecting, by a first monitoring device, a condition of an aspect of an infrastructure; transmitting data relating to the condition and a first time stamp; detecting, by a second monitoring device, the condition; transmitting data relating to the condition and a second time stamp; determining whether a difference in data indicates a problem of contamination; subsequent to an indication of the problem of contamination, determining an amount of the contamination, an approximate location of the contamination, a direction of contamination movement, and a speed of the contamination movement, based on the first time stamp and the second time stamp; determining whether a difference in data indicates corrosion within the infrastructure; and subsequent to the indication of corrosion, determining whether the data relating to the condition indicates an amount of corrosion determined to be the problem, and a level of severity of the corrosion.

Abstract: Example methods and systems for background subtraction re-initialization are disclosed. In an example method, computing system may use a set of active sensors to determine a background representation of a space that can be divided into subspaces with each subspace depicted by a quantity of data points that depends on the active sensors. The system may determine locations of objects moving the space using the active sensors and the background representation. In some instances, the system may receive an indication of a change in the active sensors and responsively determine new quantities of data points that depict each subspace after the change. The system may further adjust the background representation of the space by subtracting data points corresponding to the determined locations of the objects moving in the space from the new quantities of data points that depict each subspace of the space after the change in the active sensors.

Abstract: Aspects and implementations of the present disclosure are directed to methods and systems for a network tolerant to a network device that is temporarily absent from the control plane. In one aspect, in general, the system includes an event manager configured to send, to a controller configured to exchange control messages with a network device, a first request to temporarily withdraw the network device from control plane interactions. The event manager then triggers an event at the network device during which the network device is non-responsive to control plane interactions. After determining that the event has completed, the event manager sends the controller a second request to restore the network device. The controller is configured to request, responsive to the first request, a network application to transition to a tolerant state; and to request, responsive to the second request, the network application to transition to a sensitive state.
