THERMAL BATTERY INITIATION SEQUENCER

摘要

Electrical circuitry for initiating or firing a series of thermal batteries in sequence at predetermined time intervals, thereby enabling a series of small thermal batteries to deliver a fixed voltage output over a period of time equal to a multiple of the operating time of each individual battery. Small batteries capable of delivering a high-current density may thus be used in place of a more expensive larger battery which cannot produce the current density of a smaller battery.
