TLD America
Windsor, CT

2013  Consultant: Electrical Engineer - PLC Controls

Working closely with systems designers, I design and program PLC based control systems for the LCU-025-CUP, a compact, self-contained, trailer-mounted, Liquid Coolant Supply (LCS) Cart designed to supply chilled polyalfaolefin (PAO) coolant to the aircraft liquid coolant loop for the purpose of removing the electrical heat loads from the avionics of the F-35 Joint Strike Fighter. The LCU-025-CUP can be powered by its own diesel engine generator set supplying either 380 VAC at 50 Hz or 460 VAC at 60 Hz or can be connected to utility power. The system makes use of CANopen and J1939 to control various components such as the diesel engine electronic control unit, the variable frequency drive (VFD) to drive the compressor, and to interconnect PLC components. The continuous flow control architecture makes use of several heaters, a compressor, and a chiller to operate the system over the temperature range of -40 to 140 degrees Fahrenheit. The system uses an electronic detector to remove water from the PAO by heating the fluid and drawing a vacuum in the reservoir while recirculating the fluid internally. Likewise, particles in the fluid are detected and a sophisticated filtering system purifies the PAO to a level greater than it is supplied by the manufacturer.

CAS Medical Systems
Branford, CT

2012  Consultant: Software Engineer - Automation

I design and program automated test systems. Working from engineering design specifications I designed and programed a National Instruments LabView based test application used in the manufacture and testing of the company’s cerebral tissue oxygen saturation monitoring equipment line. The system I created allows the manufacturing engineer to create a ‘script’ of commands to be issued to the embedded processor of the unit under test over TCP/IP using a Telnet interface instructing the embedded system to run a particular test and respond with the PASS/FAIL status. The result is the automated collection of a series of tests from which a test report is automatically generated using LabView Microsoft Office Reporting Toolkit. I also designed and programmed a Microsoft Visual Studio VB.NET application to read and write 1K and 4K Dallas Semiconductor One Wire memory devices. My application writes information during the manufacturing process and reads it back during the testing process. I integrated this application to the LabView test application using the .NET framework.

DRS Consolidated Controls
Danbury, CT

2011  Consultant: Senior Software Devolment & Test Engineer
Military & Commercial Nuclear Control Systems.

DRS-CC is a company that manufacturers, produces, and developes digital nuclear controls, nuclear sensors and transmitters, custom drive controls, rotary/linear actuators, and networked Human-Machine Interface (HMI) products used in commercial nuclear power generation plants and by the US Navy. Design, development, and programming of automated Verification & Validation (V&V) systems via embedded systems programming of Texas Instruments F28335 Digital Signal Processor (DSP) and Intel 8051 Microcontroller using Object Orientated Programming (C++), in conjunction with National Instruments Lab View (LV) and Test Stand (TS). For instance, I program a test application running on the target hardware (TI F28335) to accept a hex coded command over the serial component interface and in turn switch in the various integrated circuit hardware components via the serial peripheral interface (SPI) to analysis the requested sensor input through the analog-to-digital converter (ADC) and send the result back to the requesting system, in this case the Lab View test application. In other cases the LV/TS system is running automated scripts which exercise the control system and actuator to the system requirements, automatically logging test data and generating a test report which may be evaluated for the official test record. The target hardware uses current and voltage interfaces to the actuator and RS-485 serial and Profibus network interfaces to plant Human Machine Interface (HMI) components.

Consulting position to augment client automation programming skill set.

Emhart Glass Research
Enfield, CT

1999 - 2004  Senior Systems Engineer

Electrical systems project engineer responsible for the design, development, commercialization, and deployment of two key components of the glass forming process, the 840 Glass Conditioning Forehearth Control System and the Servo Electric Take Out (SETO). Experience working to ISO-9001 and product development to Product Development Plan (PDP) methodology.


840 Glass Conditioning Forehearth Control System

The 840 Glass Conditioning Forehearth Control System project was undertaken by the company with the goal of providing the customer enhanced human machine interface (HMI) and customizable graphics, continuous data trending & job storage, a platform for future software products, VLAN (proprietary Arcnet LAN interface) compatible , multi-language support, and commonality of Emhart control components (in support of economy of scale cost reductions). The company also needed a control platform which could accept control schemes downloaded from higher level algorithms being developed by the companies thermodynamics and controls scientists.

A typical forehearth line consist of 10 control loops. The goal of this stage of the forehearth control is to keep the outer edges of the glass flow hot while cooling the center of the flow in order to achieve the optimal temperature of the gob disbursed from the spout. Any particular job (ware product) has it's own optimal temperature. All of the HMI programming on this project was performed by me using the ICONICS Genesis 32 platform.

  • Servo Electric Take Out

    A robotic arm like mechanism which removes just formed glass bottles from the blow mold setting them down on the transfer plate. The movement accelerations of the servo motors are programmable and designed to prevent backlash which would deform the still hot glass. High reproducibility enables optimized processes times.

    The SETO control system consist of a control module and an amplifier module for each glass forming section on a particular line (typically 8, 10, or 12 sections in a forming system). The control modules consist of a 486 micro processor motherboard running VX Works and a proprietary C/C++ software application, a handheld terminal port, and an Arcnet communications board for downloading job specific acceleration, deceleration, and position settings. The amplifier module drives the AC servo motor in that section and reads back encoder information for precise repeatable movements.

  • Turbomotive, Inc.
    Hamden, CT

    1992 - 1999  Chief Engineer for Control Systems, Data Acquisition, Man-Machine Interface Programming.

    Responsible for design and programming data acquisition, controls, and software man-machine interfaces for a wide variety of aircraft turboprop, turbofan and APU engines, as well as aircraft components. Hands-on experience in systems integration, field installation, and sensor troubleshooting.

    Developed real-time data reduction programs which allowed our customers to verify that the engine or component under test was meeting the requirements of a particular test point. This greatly reduced rework as our customers no longer had to remove the engine, send the results to engineering, and wait to see if the engine or component passed. The savings our customers realized made our equipment invaluable and contributed to a 7-year period of sales growth and company expansion.

    Software systems include real-time data presentation and mathematical corrections, step-by-step procedures for engine testing, alarm monitoring, custom data logging, real-time engine test pass/fail evaluation, and custom reporting. All programming done by myself or employees reporting to me. Hands-on experience in systems integration, field installation, and sensor troubleshooting.

    Beyond monitoring and reporting many systems included complex and interacting control applications. For example, at one point I design, programmed and implemented a system of some 25 interacting PID based control loops for a test stand to perform endurance "burn in" testing of the Pratt & Whitney F119 oil pump manufactured by Parker Hannifin. This pump consist of 8 sumps, each sump must have precise control of oil temperature, flow, and pressure. The system design allowed for test profiles of an indefinite number of power points for user defined intervals which do not begin until all controlled parameters reach their setpoints within user defined tolerances.

    Responsible for all activities related to control system and HMI including estimating, personnel, budgeting, schedule, purchasing, and training.

    ARINC-429 & MIL-STD-1553

    While building a test cell for the Allison (now Rolls Royce) 2100A and 2100D3 I employed SBS ARINC-429 and MIL-STD-1553 boards to off load the FADECs and integrate the Arinc and 1553 data into the test cell application (real-time so operators can conduct tests) as well as into the test reports. These servers were used again in subsequent test cells for other engine models. I have also hand coded ARINC-429 drivers to be used in test cell and test bench applications. Below I have listed some screen prints. In these examples I break out the individual bits of each word as well as decode the value.

    Aircraft Maintenance Technology featured one of our test cells (some of the screens are shown above). In this article our customer talks about how the test cell we delivered allowed his firm to optimize the testing of overhauled TFE731 turbofan engines.

    In the late 1990s Turbomotive was purchased by Canadian engineering company Aholus, a manufacturer of wind tunnel systems. After roughly two years Aholus ran in to financing issues. At this point they desolved Turbomotive and, to the best of my knowledge, desolved themselves in the mid 2000s. Many former Turbomotive employees joined a Connecticut based startup operating in the same industry.
