Energy storing device e.g. cold gas generator has measuring unit that measures stored energy of device and interface that actuates releasing unit for communication with measuring unit

摘要

#CMT# #/CMT# The device (1) has releasing unit (11) having pyrotechnic actuator with ignition pill for releasing the stored energy of the device. A measuring unit (12) measures the stored energy of pressure and/or temperature in tank of device. An interface (13) actuates the releasing unit for communication with the measuring unit, so that the functionality of the device is tested. The interface is selected from electrical interface and digital current interface conforming to PSI5standard. #CMT# : #/CMT# An independent claim is included for a method for operating energy storing device. #CMT#USE : #/CMT# Energy storing device e.g. cold gas generator (claimed). #CMT#ADVANTAGE : #/CMT# The availability of sufficient energy for exercise of security functionality can be determined by monitoring stored energy or pressure. The need for providing additional interfaces and additional wiring between controller and device can be eliminated. The efficiency examination of generator can be performed with high accuracy. The release unit can be operated easily in safe manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a block diagram of the device for storing energy. 1 : Energy storing device 10 : Energy store 11 : Releasing unit 12 : Measuring unit 13 : Interface.
