Abstract: At least one processor configured to perform operations including receiving data from a plurality of disparate data sources; distilling and converting the data into a plurality of indexes to be usable by a single data structure; retrieving first and second sets of data elements from the plurality of indexes associated with first and second pluralities of entities, respectively; generating a predicted duration of time that the first plurality of entities will remain in a first position using the second set of data elements associated with the second plurality of entities; assigning first and second velocity indexes to each of the first and second pluralities of entities, respectively, to obtain pluralities of first and second velocity indexes; comparing each of the first velocity indexes to other first velocity indexes; comparing each of the second velocity indexes to other second velocity indexes; and generating, a velocity model.

Abstract: A device for monitoring an underground utility vault environment includes environmental sensors including at least one primary sensor and at least one secondary sensor, a processor for receiving output data from the sensors and for compiling an alarm data packet, and a communications module for transmitting data from the device. The processor determines whether an alarm condition is present based on the output data from the primary sensor(s) and, when an alarm condition is present, compiles an alarm data packet comprising data derived from the primary sensor(s) and secondary sensor(s), and causes the communications module to transmit the alarm data packet. The primary sensor(s) may include a carbon monoxide sensor. The device may include a waterproof housing, a plurality of internal sensors including a gas sensor, and a port for allowing gas exchange between the environment outside the housing and the gas sensor and preventing water ingress.
