Abstract

A programmable munitions device (10) includes a transponder unit (12), a digital interface (18), and munitions unit (20). The transponder unit (12) receives a radio frequency signal from an interrogation unit (22). The transponder unit (12) decodes the radio frequency signal to obtain the digital data representing the transmitted information from the interrogation unit (22). The information is stored within a memory (14) and initiates the start of a time period within a timing unit (16). Upon activation, the munitions unit (20) reads the information within the memory (14) and a timing flag within the timing unit (16) through the digital interface (18). If the timing flag is set, indicating that the information within memory (14) is still fresh, munitions unit (20) causes the detonation of explosive material if the recognized event corresponds to the triggering event programmed within the memory (14). If the timing flag is cleared, indicating that the information programmed within the memory (14) is stale, the munitions unit ( 20) reverts to default settings within the digital interface (18) in determining whether the recognized event corresponds to the default settings.
