DETERMINING THE CHRONOLOGY AND CAUSALITY OF EVENTS
First Claim

1. A computer-implemented method comprising:
- receiving, from a first sensor at a first time, a description of a first event;
receiving, from a second sensor at a second time, a description of a second event; and
determining that the first event preceded the second event.

Abstract
An example method includes calculating latency bounds for communications from two sensors to a collector (i.e., maximum and minimum latencies). After the collector receives an event report from the first sensor and an event report form the second sensor, the collector can determine, using the latency bounds, whether one event likely preceded the other.

11. A non-transitory computer-readable medium having computer readable instructions stored thereon that, when executed by a processor of a computer, cause the computer to:
-
receive, from a first sensor at a first time, a description of a first event; receive, from the first sensor, a description of a third event; receive, from a second sensor at a second time, a description of a second event; receive, from the second sensor, a description of a fourth event; and determine that the first event preceded the second event by; determining that the first event preceded the third event; determining that the third event preceded the fourth event; and determining that the fourth event preceded the second event. - View Dependent Claims (12, 13)

16. A system comprising:
-
a processor; a computer-readable medium; and non-transitory computer-readable instructions stored thereon that, when executed by the processor, cause the system to; determine a minimum latency associated with a first sensor; receive, from the first sensor at a first time, a description of a first event; determine a maximum latency associated with a second sensor; receive, from the second sensor at a second time, a description of a second event; and determine that the first event preceded the second event by; comparing the first time minus the minimum latency for the first sensor with the second time minus the maximum latency for the second sensor. - View Dependent Claims (17, 18, 19, 20)
