PHM Technology Demonstration
The PHM Society provides an opportunity for participants to show off their diagnostic and prognostic engineering approaches through PHM technology demonstrations. The concept of the demonstrations is to offer a hands-on learning experience for attendees. Multiple daily demonstrations will be given as hands-on tutorials to small groups. Each tutorial will last for approximately 30 minutes where attendees will be allowed to ask questions.
PHM Society 2012 Technology Demonstration Sign-Up Process
All conference attendees are invited to attend interactive, hands-on hardware demonstrations. There are five demonstrations from which to choose (see below for details). Each demo is planned for approximately 30 minutes. Due to limited space, attendees must sign-up at the conference registration desk. Since the group sizes are restricted to small, demonstrations are conducted several times and time slots to attendees are allotted first come first serve on the sign-up sheet.
- The Cranfield University IVHM Center of Excellence (CoE) will present Use of Physical and Functional Approach as IVHM Design Tools for Detection and Isolation of UAV Fuel System Faults. This demonstration will showcase the IVHM CoE approach in the development of health management solutions for high-tech high value assets using COTS tools. The system under investigation is a UAV type of fuel system test rig capable of producing high quality data for normal and five abnormal scenarios (a clogged filter, a degraded pump, a stuck valve, a leaking pipe, and a clogged nozzle).The demonstration will be focused on usage of physical and functional analysis for development of fuel system health management solutions. Output of the functional model (various sensor sets and diagnostic rules associated which each individual sensor set solution) will be demonstrated on the fuel rig.
- The Inherently Conductive Polymer (ICP) Based Structural Health Monitoring (SHM) Sensing System demonstration is provided by Crosslink (www.CrosslinkUSA.com). The ICP based SHM sensing system is composed of SHM sensors, a wireless transmission module, and central control station. Two types of SHM sensors (strain gauge and acoustic emission sensor) will be used. The signals captured by these strain/stress sensors and damage sensors will be wirelessly communicated to the central control station. The data collection & analysis, diagnostic, and prognostic calls will be handled by the central control station.
- The Electrical Power System (EPS) Testbed demonstration is provided by NASA Ames Research Center (prognostics.nasa.gov). The EPS Testbed provides a means for evaluating diagnostic algorithms through the controlled insertion of faults in repeatable failure scenarios. This demonstration will give an overview of the testbed hardware, software, and datasets. We will connect remotely to the testbed at NASA Ames to show a real-time demonstration of fault injection and on-line diagnosis using Hybrid Diagnosis Engine (HyDE), a diagnostic algorithm developed by researchers at Ames.
- The Modular COTS Hardware and Software for Commercialization of Prognostics Systems demonstration is provided by National Instruments (www.ni.com). It illustrates a COTS platform for integrating a prognostics system. Signal processing options for feature extraction are also shown. Modular hardware components and a source code framework are reviewed to describe the COTS components used.
- The Smart, Ultra Low Power, Wired and Wireless Sensor Suites for PHM demonstration is provided by Sporian Microsystems, Inc. (www.sporian.com). The demonstration will feature an operating network of wired and wireless PHM sensor suites and a gateway computer to display and visualize collected PHM data. The demonstration will be fully interactive including temperature and humidity measurements, inertial measurements, and over-the-air programming of smart-sensor parameters. Parameters such as sensor polling frequency and alarm threshold will be interactively varied.

NOTE: Demonstration hardware, concepts, material, data, etc., were required to be cleared for public release.
Interested parties submitted a brief write-up (mini-proposal) of their proposed PHM technology demonstration, including:
- demonstration description
- amount of attendee interaction expected (additional consideration will be given for this criterion)
- educational value
- demo requirements (size, weight, facilities needed, etc.)
- what needs to be shipped
- how it needs to be stored.
As an incentive, a reimbursement of up to $1000.00 (US) is offered to each demo team for shipping expenses. Tables, chairs, power, and a flat panel display are provided if required.
