    • There is provided an electrical pulse splitter (EPS) for an explosives system (10), the explosives system comprising an electrical pulse generator (EPG), the electrical pulse splitter (EPS), and first and second explosive charges (Ch1, Ch2) having respective first and second electrical initiators (D1, D2), The electrical pulse splitter (EPS) is configured to receive a primary electrical pulse from the electrical pulse generator (EPG), and to output first and second electrical pulses to the first and second electrical initiators (Ch1, Ch2) respectively. The second electrical pulse is output a length of time after the first electrical pulse is output, and the electrical pulse splitter is powered by the primary electrical pulse.

    • An acoustic reflector suitable for use as a reflective target for navigational aids and for location and re-location applications. The acoustic reflector comprises a shell arranged to surround a solid core. The shell is adapted to transmit acoustic waves incident thereon into the core. Within the core the acoustic waves are focused before being reflected from an opposing side of the shell to provide a reflected acoustic wave. The shell has at least two areas of transmissibility such that the waves incident on the shell follow separate paths within the core before being re-radiated and combining constructively to provide an enhanced reflected acoustic wave at one or more pre-determined frequencies.
    • 适用于导航辅助设备和位置和重新定位应用的反射目标的声反射体。 声反射器包括布置成围绕实芯的外壳。 壳体适于将入射到其上的声波传播到芯中。 在核心内,声波在从外壳的相对侧反射之前聚焦,以提供反射的声波。 外壳具有至少两个传输区域,使得入射到壳体上的波浪在重新辐射之前遵循分离的核心路径,并且建设性地组合以在一个或多个预定频率处提供增强的反射声波。
