Abstract: An apparatus and method for determining presence and absence of one or more individuals in an occupancy space. The apparatus comprises a processing apparatus and a memory, the memory being configured for storing data indicating that expiry of a timer was responded to, and data indicating that a signal from a sensor was responded to. The processing apparatus has a number of modes in which it is responsive to a signal from a sensor and/or responsive to expiry of a timer so as to determine presence and absence.

Abstract: A system comprises a first detector for detecting whether a multi-occupancy space is occupied by at least one individual and a plurality of second detectors for detecting whether an individual is present in each of a respective plurality of spaces within the multi-occupancy space. A controller is configured to monitor whether an individual is present in the multi-occupancy space based on a signal derived from the first detector. If the presence of at least one individual is detected based on the signal derived from the first detector, the controller determines occupancy of the multi-occupancy space based on signals derived from the plurality of second detectors.

Abstract: A system for continuous analytics comprises an in-memory storage and a processor. The processor receives a query that indicates an analytic function to be performed on a combination of static data and real-time data. The processor loads the in-memory storage from a first source external to the processor with data that was stored as the static data. At the same time that the in-memory storage is already loaded with the static data, the processor continuously receives ephemeral real-time data as it is being generated by a second source external to the processor. The processor runs the analytic function from the query against the in-memory storage loaded with the first data and the real-time data that is being continuously received, in combination, to produce a result of the analytic function. The result is stored and time-stamped in the in-memory storage as an analytic cube.
