          Question:
          How to detect sudden increase or decrease in value for an event using proton run time?

          Description:
          I am developing an application using proton CEP and Orion Context Broker. I have sensor that updates the temperature and CEP gets the temperature update as an event. I want the CEP to produce an alert if there is a difference of 10 in two consecutive updates.

          For example:
          Last update from sensor is 35. If the next update is less than 26 or greater than 44 I need CEP to produce an alert.

          How can I write a rule to achieve this?
