Interoperability: RTIs Perspective

Interoperability: A PerspectiveStan SchneiderReal-Time Innovations, Inc. CEO & IIC Steering CommitteeYour systems. Working as one.1

Levels of InteroperabilityWhat level?Mandate?Guidelines?How?When?

RTIs Experience~800 DesignsHealthcareTransportationCommunicationsEnergyIndustrialDefense15+ Standards & Consortia Efforts


Interoperable Navy Open ArchitectureNext-generation of Lockheed AegisRaytheon DDG 1000Raytheon SSDSLCS (Lockheed and GDAIS)Raytheon LPD-17Many more, US and alliesHighly distributed systems include radar, weapons, displays, controls

Standards-based, high-performance middleware breaks vendor lock-in, drives interoperability ,and future-proofs the architectural design

2014 Real-Time Innovations, Inc.4Facilitate Plug-n-Play Across VendorsAudi hardware-in-the-loop simulation feeds realistic data to components for testingThe system offers plug-n-play between simulation vendor solutionsRTI middleware enables a modular test environment that scales to work with hundreds of devices

5Integrate New and OldThe VW Driver Assistance and Integrated Safety system combines radars, laser range finders, and video to assist safe operationThe V-Charge program demoed a self-driving vehicle in 2014The system integrates with existing CANbus through VW Cargate ECU

RTI enables advanced reactive systems in transportation

Revolution"GE Healthcare chose the DDS standard because it can handle many classes of intelligent machines.

RTI Connext DDS satisfies the demanding requirements of our devices and supports standardization on a single communications platform across product lines."

-- J Gustavo Perez, General Manager for MI&CT Engineering

7Improve Safety by Connecting DevicesHospital error is the 6th leading cause of preventable deathThe Integrated Clinical Environment (ICE) standard specifies interoperability for medical devicesRTI Connext DDS ties together many classes of devices from many vendorsRTI Connext DDS met all our needs whether were handling 12 patients, or 200. -- DocBox Founder, Tracy Rausch
