Components of HIPPS
A system that closes the source of over-pressure within 2 seconds with at least the same reliability as a safety relief valve is usually called a HIPPS. Such a HIPPS is a complete functional loop consisting of:
- sensors, (or initiators) that detect the high pressure
- a logic solver, which processes the input from the sensors to an output to the final element
- final elements, that actually perform the corrective action in the field by bringing the process to a safe state. In case of a HIPPS this means shutting-off the source of overpressure. The final element consists of a valve, actuator and solenoids.

“Hence, a generative grammar must be a system of rules that can iterate to generate an indefinitely large number of structures. This system of rules can be analyzed into the three major components of a generative grammar: the syntactic, phonological, and semantic components.”
—Noam Chomsky (b. 1928)
