Abstract:
The present disclosure provides an event stream processing system, comprises a gateway device and an external module. The gateway device comprises an event processing engine, and the external module comprises external processor. The event processing engine comprises an event grouping unit, a catch-collector, a processor and an event generator. The event processing engine processes a plurality events of the event stream corresponded to a rule. The event grouping unit groups the events corresponded to the rule. The catch-collector couples to the event group unit, configured for storing a first group event. The processor couples to the event group unit, configured for processing a second group event. The external module calculates the first group event and generates a first processing result. The event generator integrates the first processing result of the first group event and a second processing result of the second group event and generates a derived event.
Abstract:
An electronic apparatus includes a selection unit, a storage unit and a processing unit. The selection unit and the storage unit are coupled to the processing unit. The selection unit selects a first reference point proximate to the electronic apparatus. The storage unit stores a plurality of second locations of a plurality of second reference points. The processing unit executes a single-point distance measurement between the electronic apparatus and a first location of the selected first reference point, provides the electronic apparatus auxiliary positioning information by selecting the second locations stored in the storage unit and generates a speculative location of the electronic apparatus by further computing the results of the single-point distance measurement and the auxiliary positioning information.
