摘要: A small arms firing effects simulator utilizes a modular construction to egrate with the magazine of a weapon such as a rifle. The modular design resembles the ammunition clip and houses an expendable plastic coated plurality of pyrotechnic charges. An electrical control circuit is also housed within the module and serves to interface the pyrotechnic charges with the firing of the weapon, including semi-automatic and automatic firing as well as disabling the weapon when all rounds have been fired.

摘要: A bi-directional fibre-optic coupler providing about 70 dB to about 100 dB isolation from near end transmitter radiation in a system that transmits signals in opposite directions over a single fibre and thereby provides a low-loss coupler having operational characteristics to handle reception and transmission with sufficiently low value of crosstalk.
