Classification: CPC G | IPC G

Claim 10:
11. An event detection unit comprising:
at least one processor;
a plurality of sensors coupled to the at least one processor, each of which is to measure a different characteristic of an event of a particular type; and
at least one memory accessible to the at least one processor and containing instructions, execution of which by the at least one processor causes the event detection unit to perform a process that comprises,
for each of the plurality of sensors,
receiving a sensor reading from that sensor;
obtaining a weight indicating contribution of a sensor reading of that sensor to detection of an event;
generating a non-event probability indicative of whether the sensor reading for that sensor corresponds to a non-event; and
generating an event probability indicative of whether the sensor reading for that sensor corresponds to an event;

generating a combined non-event probability based on the weights and the non-event probabilities from the plurality of sensors;
generating a combined event probability based on the weights and the event probabilities from the plurality of sensors;
determining that an event has been detected based on the combined non-event probability and the combined event probability; and
outputting an indication that the event has been detected in response to said determining.
