Conference proceedings front matter may contain various advertisements, welcome messages, committee or program information, and other miscellaneous conference information. This may in some cases also include the cover art, table of contents, copyright statements, title-page or half title-pages, blank pages, venue maps or other general information relating to the conference that was part of the original...
In determining the optimal allocation of spare parts and labor in a machine shop, in addition to the planned inspections, the random failures must be considered. The expected number of failures must be therefore assessed. At present, literature on the subject mostly discusses minimal repairs and failure replacement, giving only a little attention to partial repairs. These models ignored the time period...
A trend has emerged toward the development of critical systems hosted on the Ethernet databus. Ethernet enjoys unprecedented standardization in commercial networks, and a vast network of engineers with training and experience. It is now commonly known that implementations of deterministic Ethernet for avionics networks known as ARINC 664 part 7 exist on several commercial airframes. In other platforms,...
This Paper defines a method of Certifying a Test Station for use by an organization's Production team, and for Validating its proper functionality. The Production team of any organization is the customer of the Test Equipment development team. The deliverable to the Production team is the Test Station, whose performance must be Validated in order to guarantee that it can adequately provide Pass/Fail...
The aviation industry has many aircraft in use after more than twenty years of life with some aircraft achieving the fifty years of life milestone. The avionics aboard the older aircraft are based on circuitry elements with diminishing or no manufacturing sources. Entire families of integrated circuits are no longer available, such as the early Intel processors and peripherals, 54C series CMOS logic...
This paper describes the recent best practice guidelines incorporated into the IEEE Std 1641.1 amendment, to both help users with the techniques to develop their own signal models for their test systems, but also using the ATLAS as a comprehensive source of material, how to map traditional ATLAS NOUNS and Modifiers into reusable TSF libraries, for incorporation into tools and ATE platform as test...
Deployed test and health monitoring systems must actually manage two tasks: (1) the testing and monitoring the device under test, and (2) the testing and monitoring the test system itself. The ability to isolate and identify faults is crucial to deployed test and health monitoring systems. Understanding failure mechanisms provides invaluable insight regarding whether the device under test is, in fact,...
As defense budgets have decreased in recent years while the equipment becomes more complex, Automatic Test Systems have also become more complex. At the same time system engineering requirements demand more and better requirements verification. One recent program had over 1000 requirements that needed some sort of verification. This paper discusses the techniques and statistics used to capture, evaluate,...
For modern Automatic Test Equipment (ATE) one of the common tasks is the process of re-imaging and re-configuration of the test station. This can occur due to hardware faults, disk corruption, or planned software updates. With the requirement of modern systems to also have Information Assurance (IA) updates, this can increase the frequency of re-imaging a system (as it may be more efficient to do...
As the new technology of test and diagnosis, condition monitoring and health management has been the core system of autonomous logistics of military equipment, and it has important role in ensuring the combat readiness, improving the operational effectiveness and reducing the total cycle cost of equipment. In this paper, focused on the condition monitoring and health management of active electronically...
AXie is a new standard for constructing automatic testing systems (ATS). It provides an open, high-performance platform for instrument modules. However due to some practical consideration, such as the reuse of existing modular instruments or bench top instruments, compatibility should be taken into account when constructing a new ATS based on AXIe system. In this paper we propose a mixed ATS architecture...
Automated Test Systems (ATSs) can join the Internet of Things (IoT) at multiple layers and benefit both the overall IoT concept as well as advance the goals of ATSs. Logistics and sustainment are traditionally brought into the IoT conversation through asset tracking, transportation, and Health and Usage Monitoring Systems (HUMS). However the IoT has additional aspects that can be related to logistics...
The initial focus for the cyber security community has been to make operating systems and networks more secure and harder to penetrate. These improvements are making it more difficult to exploit these systems, driving attackers to turn their attention to embedded systems and hardware exploitation. It is expected that new threats from improperly secured embedded operating systems, poorly defended firmware...
To test the stability and performance of an airplane, it's necessary to adjust its barycenter during the trial fight. To cope with this issue, a novel real-time adjustment system for the barycenter of airplane is proposed based on compactRIO (cRIO). With the unique construction of cRIO, the designed system has adopted the hardware-software co-design concept. The program-able hardware (FPGA within...
In this paper, a customized software tool to manage remote access to test equipment is presented. The software tool is developed using LabWindows/CVI and runs on Ethernet over TCP protocol. Ethernet is used as the media for communication and control since a local-area-network (LAN) infrastructure is mostly available in a facility; and almost all commercial-off-the-shelf (COTS) equipment manufacturers...
In recent years, synthetic test instruments have become increasingly popular in the automatic test equipment (ATE) market. This type of instrument gives users the ability to create custom solutions to better meet their test requirements. FPGA (Field Programmable Gate Array) based solutions are the most common synthetic test instrument on the market today. FPGA based solutions can work well due to...
Being able to record and analyze data securely have a paramount importance to meet the needs of both military and civilian applications. Therefore, data acquisition systems are used to meet the needs of complex applications. A data acquisition system capable of data conversion, collection and transfer is described in this paper. This system is implemented on FPGA, because of high processing speed...
