Solution Overview
Problem
Aircraft platforms with legacy MIL-STD-1760 interfaces are incompatible with modern UAI-equipped weapons, requiring significant software upgrades and hardware modifications, which is costly and inefficient for integrating miniature munitions.
Innovation Solution
An interface bridge that translates between the MIL-STD-1760 interface and UAI, enabling real-time logical or messaging translation, time stamp conversion, and data conversion to facilitate the integration of UAI weapons on legacy platforms without major avionics software changes.

Engineering Contradiction Analysis
1Adaptability or versatility
If legacy MIL-STD-1760 interfaces are used on aircraft platforms, then compatibility with older weapon systems is maintained, but integration with modern UAI-equipped weapons becomes incompatible requiring significant software upgrades and hardware modifications
Solution Approach 1:
An interface bridge is introduced as an intermediary device between the legacy MIL-STD-1760 bus controller and the modern UAI remote terminal. The interface bridge receives messages from the MIL-STD-1760 bus controller, detects the time stamping technique used, determines a recomputed time tag, and transmits the message with the recomputed time tag to the UAI remote terminal, thereby enabling compatibility without modifying the legacy aircraft platform software.
Solution Approach 2:
The interface bridge creates a virtual copy or translation layer that mimics the UAI protocol on the legacy MIL-STD-1760 platform. By implementing a software-based translation mechanism, the system replicates modern UAI functionality on older hardware without requiring physical hardware modifications to the aircraft avionics.
2Adaptability or versatility
If significant software upgrades and hardware modifications are implemented to achieve compatibility, then modern UAI weapons can be integrated, but integration costs increase significantly
Solution Approach 1:
The interface bridge serves as a cost-effective intermediary solution that avoids expensive platform-wide software upgrades and hardware modifications. By isolating the translation functionality to a single interface bridge unit, the integration cost is dramatically reduced while maintaining full compatibility with modern UAI weapons.
Solution Approach 2:
The integration solution is segmented into a modular interface bridge that handles only the protocol translation function, separate from the main aircraft avionics system. This segmentation allows the legacy platform to remain unchanged while adding modern capability through a standalone, affordable interface device.
3Measurement precision
If time stamp conversion is implemented at the interface bridge, then accurate time tagging is ensured for precise weapon operation, but processing complexity increases
Solution Approach 1:
The interface bridge autonomously detects which time stamping technique is used in incoming messages and automatically determines the appropriate recomputed time tag without external intervention. The system self-manages the time stamp conversion process by identifying the message format and applying the correct conversion algorithm, thereby maintaining precision while minimizing operational complexity.
Solution Approach 2:
The interface bridge incorporates feedback mechanisms where it monitors incoming message formats, detects the time stamping technique used, and adjusts its processing accordingly. This feedback-driven approach allows the system to handle multiple time stamping techniques dynamically without requiring complex manual configuration or processing logic.
Data Source
AI summary
A technology is described for converting a time tag in a message. The message can be received from a military standard-1760 (MIL-STD-1760) bus controller. The message can include a time tag in accordance with a first time stamping technique. The time tag in the message can be detected as being in accordance with the first time stamping technique based on contents of the message. A recomputed time tag for the message can be determined in accordance with a second time stamping technique. The message with the recomputed time tag can be transmitted to a Universal Armament Interface (UAI) remote terminal.
