Abstract

The present invention relates to an object oriented architecture that includes a plurality of host aircraft interface objects that enable a plurality of different host aircraft or variants to be attached or interfaced to an associated store, such as a targeting pod or a weapon system. The union of all aircraft hosts and variants are packaged and maintained as one executable capable of adapting to the predetermined suite of identified hosts and host variants. At least one or more interface objects provide a virtual translation layer which is dynamically determined and allocated during instantiation. Auto detection of the host aircraft/host aircraft variant provides the specific interface protocol by which the store can process and provide status via a predetermined signal format.

Claims

1. A method of installing, on a weapons, targeting, or tracking platform, which is a host system, a weapon, or targeting or tracking unit, which is an associated store that operates with multiple hosts and host variants, the method comprising the steps of:

attaching the associated store directly to the host system via at least one attachment point in said store;

detecting the host system with the attached associated store;

establishing communications between the associated store and the detected host system, said establishing including activating a communication control interface in the associated store;

capturing incoming control data from the detected host system with said communication control interface;

translating messages received from the detected host system into a format recognizable to said associated store and messages sent from said associated store into a format recognizable by said host system with a message translator in said store; and

translating the captured control data within said associated store according to a functionally mapped software architecture for the associated store via a virtual translation layer;

wherein the store is a single device that includes the communication control interface, the message translator;

the virtual translation layer, and said attachment point.

2. A method according to claim 1 wherein the host system is an aircraft.

3. A method according to claim 2 wherein the host aircraft includes a plurality of variants.

4. A method according to claim 1 wherein the associated store is a targeting pod.

5. A method according to claim 1 wherein the associated store is a weapon.

6. A method according to claim 3 where detecting further includes utilizing predetermined and unique interface protocol attributes relating to message size and type of host sub-addresses to identify a correct host variant.

7. A method according to claim 1 where said activating includes establishing parameters of said communication control interface based on the host system detected during said detecting.

8. A method according to claim 1, where the communication control interface includes a common physical interface;

and

where detecting includes attaching the store to the host via the common physical interface.

20. The method of claim 1, the method further comprising isolating detected host system attributes from common core capabilities of the associated store.

22. The method of claim 1, where said translating the incoming control data includes associating an incoming control signal with at least one object function in the software architecture.

25. The associated store of claim 22, where the common core capabilities are represented by at least one class in the software architecture.

9. An associated store, which is a weapon, or targeting or tracking unit, configured to operate with multiple hosts and host variants, which are weapon, or targeting or tracking platforms, the store comprising:

at least a first processor that detects the attached host system;

a communication control interface that controls communications with the detected host system and captures incoming control data from the host system;

a message translator that translates messages received from the host system via the control interface;

a virtual translation layer that translates the incoming control data according to a functionally mapped software architecture for the store;

at least one module that is responsive to the first processor and communicates with the host system; and

at least one attachment point configured to attach the store directly to the host, where said attachment point includes at least part of said communication control interface;

wherein the processor, communication control interface, message translator, virtual translation layer, module, and said attachment point are included in a single associated store device.

10. An apparatus according to claim 9 where the host system is an aircraft.

11. An apparatus according to claim 10 wherein the host aircraft includes a plurality of variants.

12. An apparatus according to claim 9 wherein the associated store is a targeting pod.

13. An apparatus according to claim 12 wherein the targeting pod includes a FLIR, a digital video module and a recorder.

14. An apparatus according to claim 12 where the targeting pod further includes a laser control module and a navigation module.

15. An apparatus according to claim 9 where the associated store is a weapon.

16. An apparatus according to claim 10 wherein the associated store is a targeting pod and the host aircraft includes a plurality of variants.

17. An apparatus according to claim 16 where the first processor processes predetermined and unique interface protocol attributes relating to message size and type of host sub-addresses to identify a correct host variant.

18. An apparatus according to claim 9 where the first processor establishes parameters of the communication control interface based on the detected host system.

19. An apparatus according to claim 9, the apparatus further comprising a common physical interface that attaches the associated store to one of a plurality of hosts or host variants;

and

where the first processor detects the host system via the common physical interface.

21. The associated store of claim 9, where the virtual translation layer isolates detected host system attributes from common core capabilities of the associated store.

23. The associated store of claim 9, where virtual translation layer translates the incoming control data by associating an incoming control signal with at least one object function in the software architecture.

24. The method of claim 21, where the common core capabilities are represented by at least one class in the software architecture.
