    • A stab type fuze mechanism, such as the 30 mm M759 fuze mechanism, which utilizes a generally horse shoe shaped configuration anti-setback spin clip initially lodged in a grove within the body of a target sensing probe, but extending partially therefrom, which extending part rests against a ledge within the aluminum o-give—located rearward from the target sensing probe; thereby preventing the target sensing probe from moving rearward within the fuze during firing and setback. After firing, with the onset of spin, the anti-setback spin clip will open, expanding away from, out of, and clear of the grove and into a cylindrical channel in which the target sensing probe is lodged. Due to a thinned area at the apex of the clip, the expansion of the anti-setback spin clip will be a plastic deformation and the clip will remain expanded. With the expanded clip entirely clear of the grove—when the cartridge impacts its target, either a hard target, or a soft target, the obstructed forward travel of the cartridge will force the target sensing probe rearwards to impact the firing pin located immediately rearward thereof; thereby, forcing the firing pin rearward and initiating the firing train of the fuze, and subsequently, igniting the secondary explosive within the cartridge to cause detonate thereof.

    • A target discrimination system monitors an acceleration switch signal to determine an impact of a projectile on a target. During a sample period of approximately 1.0 milliseconds, the system repeatedly samples the acceleration switch signal, compares the sampled acceleration sensor signal with a reference voltage, and sets a comparator data output to logic one if the sampled signal exceeds the reference voltage. Otherwise, the comparator data output is set to logic zero. The system counts the instances that comparator data output equals logic one during the sample period and executes a selected delay. The selected delay is approximately 50 milliseconds if the counted number of instances exceeds a predetermined threshold of approximately two-thirds of the samples and, otherwise, the selected delay is approximately 10 milliseconds. The selective delay enables target discrimination and selective detonation of a projectile.
    • 目标识别系统监视加速切换信号以确定射弹对目标的影响。 在大约1.0毫秒的采样周期内,系统重复采样加速度开关信号,将采样的加速度传感器信号与参考电压进行比较,如果采样信号超过参考电压,则将比较器数据输出设置为逻辑1。 否则,比较器数据输出设置为逻辑0。 系统对采样周期内比较器数据输出等于逻辑1的实例进行计数,并执行选定的延迟。 如果所计数的实例数超过样本的大约三分之二的预定阈值,则所选择的延迟大约为50毫秒,否则所选择的延迟大约为10毫秒。 选择性延迟使得目标辨别和弹丸的选择性爆炸。
