Abstract

A device for indicating the type of ammunition provided in or on the ammunition unit comprises a distinguishable specific identification allocated for each type of ammunition and made up of electronic device with different electrical characteristics depending on the type of ammunition, including a status-changing element which can change between at least two statuses having different electrical characteristics. A control circuit is provided for controlling change-over of the status-changing element between the at least two statuses having different electrical characteristics, the process of the status changes controlled by the control circuit being indicative of the type of ammunition contained in the ammunition unit.

Independent Claims | See all claims (11)

1. 1. A device for indicating the type of ammunition provided in or on the ammunition unit comprising:a) a distinguishable specific identification means allocated for each type of ammunition and made up of electronic means with different electrical characteristics depending on the type of ammunition, said electronic means including a status-changing element which can change between at least two statuses having different electrical characteristics; andb) a control circuit for controlling change-over of said status-changing element between said at least two statuses having different electrical characteristics, the process of the status changes controlled by the control circuit being indicative of the type of ammunition contained in the ammunition unit.
2. 6. An ammunition unit comprising:a cartridge;at least one ammunition charge in said cartridge, means for activating release of the ammunition charge in response to an activating signal and a device for indicating the type of ammunition charge which is contained in the ammunition unit, said device including:a) a distinguishable specific identification means allocated for each type of ammunition and made up of electronic means with different electrical characteristics depending on the type of ammunition, said electronic means including a status-changing element which can change between at least two statuses having different electrical characteristics; andb) a control circuit for controlling change-over of said status-changing element between said at least two statuses having different electrical characteristics, the process of the status changes controlled by the control circuit being indicative of the type of ammunition contained in the ammunition unit.
3. 8. A release system comprising:at least one release unit having a magazine for ammunition units, each ammunition unit being provided with a device for indicating the type of ammunition charge contained in the ammunition unit, the device including a distinguishable specific indication means for associated ammunition type and including a status-changing element with at least two statuses having different electrical characteristics and a control unit for providing electrical input signals to said ammunition unit and means for detecting status changes of said status-changing element of said indicating device and for determining the type of ammunition based on the status changes.
