Problem statement : deriving from how fire alarms work and are networked.

                    electromagnetic/hydraulic lever based push/pull release mechanisms.

Opportunity : Emergency exit are key mechanism's for any structural design,

              deriving from structural cabling....security survielance equipments,

              also some schema used in air-craft ...emergency-exit design,

              ...deriving computer-systems used in air-craft design ...


               ....innovative security/safety/fire/emergency exit design that lock/un-lock based on

               various factors used in security survielance ...viz. fire-alarms/security-camera/monitoring systems,

               access to emergency equipment can also guided by these factors (access to fire-extinguishers/foam ..etc)
