Over the years Page Associates has been involved in a number of projects that
contribute to our wide range of experience. A sampling of the projects includes:
- Medical Industry - Laboratory Instrument Control
Developed software and collaborated in the hardware design of a series of medical
devices which use electrofusion/electroporation to deliver medication or other
substances into the cells of the subject under treatment. The mechanism involved
is a precisely controlled sequence of electrical pulses which open gaps in the
cell walls of the cells to be treated. The software maintained a library of
pulse sequence protocols, controlled the administration of the pulse protocols,
and maintained records of their use. The software was written in a combination
of VB.NET and C.
- Filtration Testing Industry - Gas Mask Testing Instrument
Developed software and electronics of a next generation instrument used to test
the quality and fit of military gas masks. I was responsible for the
conceptualization, design, fabrication, and testing of two circuit boards
involving three microprocessors, a touch-screen LCD interface and high precision
analog circuitry. In addition to the electronics, I developed all required
software both for testing the low-level functionality of the machine and for
the end user interface. I completed the project on schedule and below cost.
The implementation involved a combination of microprocessor types and was
coded in C.
- Filtration Testing Industry - Salt Based Aerosol Filter Testing Instrument
Designed microprocessor based hardware and software for the control system of an
instrument to test commercial filters and filter materials using a salt based aerosol.
The design involved a distributed microprocessor system with eight microprocessors
and a touch-screen GUI control panel. Each of the microprocessors is capable of
stand-alone operation which is used in diagnostic testing. The modular approach
to the system design was targeted to minimize cost and maximize flexibility of
expansion and ease of maintenance. The instrument successfully passed all
commercial code compliance requirements (both safety and EMC/EMI). We also
provided support for the transition to manufacturing. The design included
a combination of PIC32, PIC24, PIC18, PIC16, and SiLabs microprocessors and
was coded in C.
- Filtration Testing Industry - Oil Based Aerosol Filter Testing Instrument
Redesigned the control system for an instrument to test filter materials using
an oil based aerosol. The effort included re-write of the existing software
from an old version of Basic to C. The re-write also included customer
requested feature enhancements. In addition, I redesigned the control system
in a way that cut the production cost in half while adding additional
capabilities. The microcontroller used was an 8032 variant.
- Filtration Testing Industry - Hot Oil Aerosol Generator
I developed an electronic control system for an instrument that produces
oil-based aerosols for industrial testing applications. The instrument
used a hot inert gas for the aerosol generation and the electronics were
carefully designed to ensure the safe operation of the instrument. The
resulting instrument complied with all relevant international code
requirements and was lower in manufacturing cost than its predecessor.
- Chemical Industry - Order Entry and Fulfillment
Developed a system for ordering characterized chemical standards for a large
chemical company. Using the web interface, a customer could determine what
compounds were available and place orders for samples. Once the orders were placed,
the system queued orders for fulfillment and prompted a technician through the
retrieval of the compounds from inventory and the weighing of the appropriate
amounts. The software provided all required labeling for the samples, invoices and
all the documentation (MSDS, Chain of Custody, etc.) that were required for
international shipment of the compound. In addition to the ordering functions of
the system, the inventory of compounds was tracked including storage location,
special handling considerations, and a timetable for re-characterization of the
- Chemical Industry - Order Fulfillment
Developed an order fulfillment system that enabled researchers to retrieve samples
from a large inventory of research compounds. The system received orders from a
mainframe order entry system and provided software for the scheduling of order
processing, the retrieval of compounds from a semi-automatic compound storage and
retrieval system and management of the weigh stations that dispensed the samples
including the preparation of shipping documents. The system replaced an aging
hardware and software with no interruption in service and a major (3X) increase in
- Chemical Industry - Instrument Interface
This job involved the development of an interface between a Brinkman Titrator and a
testing lab's sample submittal and LIMs systems. The program was responsible for
prompting the operator through sample preparation and testing. The software produced
appropriate labels for the samples and printed reports as well as making the results
available to the LIMS.
- Fibers Industry - Automated Testing
Designed software to operate a custom sample analyzer for a large fibers company.
The system handled the sample preparation and logging into the testing system.
Since the testing procedure involved toxic materials, the prepared samples were
inserted into a robotic testing station that performed the test without human
intervention. Upon completion of the test, the waste products were disposed of and
the results of the testing transferred to the plant-wide process quality control
system. Page Associates developed all the software involved from the sample
preparation to the logging of results, including the control software for the
- Fibers Industry - Automated Testing System
Participated in hardware design and developed all software for an automated yarn
testing system. The system consisted of a sample dispatcher and four test
instruments. A rack of yarn bobbins were rolled up to the dispatcher and the free
end of the yarn was introduced to the dispatcher. When the machine operator
pressed "Start", the dispatcher would deliver a sample of yarn to each of the test
instruments until all bobbins on the rack had been tested by all instruments. Test
results from the various instruments were collected by the dispatcher and combined
into a complete report on the testing of the rack. The report was both printed and
shipped to a central database.
- Equine Industry - Registry Management Software
Developed a complete registry management package for a major equine breed registry.
The package handled all aspects of the registry, both of the membership and their
horses. A full range of reports is available including membership directories,
labels, membership statistics, etc.
- Equine Industry - Website
Designed a website for an equine breed registry which include information of
pedigrees of horses, advertising for sellers, and reference material on the breed.
The site was designed with flexibility in mind and most of the changeable material
on the site can be managed by the registry office without involving outside support.
- Food Industry - Quality Testing
Replaced a DOS C application with a Win32 GUI application for a food processing
company. The replacement was driven by the need to add features, replace aging
hardware, and improve reliability. The application was responsible for the
automated testing of samples of the incoming crop to determine the quality of the
crop and thus the payment to the producer. The timing on this project was driven by
the harvest schedule and was developed on time and the conversion of eight testing
stations and training of the operators was completed on schedule for the harvest.
- Fibers Industry - Website
Performed a major redesign of a website for a large specialty fibers company. The
enhancements included improved navigation, expanded information, and slide-
shows/movies depicting the use of the products.
- Optoelectronics Industry - Automated Testing
Translated an unsupported application written in HPVEE to Visual Basic. The
application was designed to control a test station that measured properties of an
optical device. The station operator was prompted through the identification of the
device to be tested and the connection of the device to the test fixture. Once
connected, the station performed a series of automated tests by communicating with
optical spectrum analyzer and signal generators through a GPIB buss. The results of
the testing were made available in a report and a datafile.
- Fibers Industry - Test Instrument Control Software
Provided enhancements and support for an orphan legacy application (PC DOS/C Language)
which controlled a multiproperty test instrument. Developed a Win32 replacement
for the application which retained all the functionality of the old software and
added numerous usability and maintenance enhancements.
- Petroleum Industry - Oil Tank Measurement System
Developed control and analysis software for a proprietary system for the measurement
of wall thickness in oil tanks which allowed tanks to be inspected without
emptying the tank first.
- Instrument Manufacturer - Instrument Control Software
Developed embedded control software for an instrument which measures the properties
of air filtration devices.
