  • Electronic time opener and opener setter system
    Patent number: 3986457
    Abstract: An electronic time opener and opener system is utilized for initiating the pening of a plurality of munition cannisters at an accurate settable time after ejection from a high speed aircraft. Analogue circuitry is used in the opener setter to measure the capacitance of an RC circuit of the electronic time opener, immediately prior to cannister ejection. Upon the basis of this pre-ejection measurement a proper voltage charge is generated to obtain sufficient energy to actuate a detonator in the munition at the proper time. The combined opener and opener setter system permit accurate tuning while using wide tolerance capacitance components in the electronic time opener.
