A system for
characterizing the 3-dimensional output profile of an x-ray probe tip
source. It included multi-axis motion control of the x-ray source and
the ion chamber x-ray detector, flexible displays with overlaid graphs, and
automated curve fitting and treatment planning. |
|
|
Feedback control
systems for varying probe tip x-ray output during radiation treatments. |
|
|
Production
test systems for an artery plaque mapping catheter product and its laser and
detector components. Also, a control and infrared spectra acquisition system
for the earlier clinical trial version of the product. |
|
|
A powerful,
flexible research system for automatically examining blood slides and
counting cancerous cells. The system included microscope stage
position and magnification control, microscope camera control, image
analysis, and many levels of configuration and calibration. |
|
|
A prototype
electrochemical blood analysis system with pump and valve control, flexible control and
measurement sequence scripting, reading of sensors, and display and storage
of results. |
|
|
A large LabVIEW program that
acted as the "firmware" inside a commercial automated radiopharmaceutical synthesizer. The program
controlled syringes, valves, and heaters, measured temperature, pressure, and radiation level, and
provided the user interface to control the instrument including real-time animated
illustrations. |
|
|
A field-test system
characterizing the performance of aircraft weapons laser targeting during flyover. The
system recorded laser spot position on a target many times per second using a video camera
and real-time image analysis. |
|
|
An instrument
control, data acquisition, dose monitoring, and session logging system for
exposing military aircraft to RF radiation for susceptibility testing. |
|
|
A field-test system characterizing
the signal strength spatial pattern of military transmitting antennas. |
|
|
A monitoring
and logging system in the printing press room at a major metropolitan
newspaper. The system sensed and graphed the speed and phase of different
newspaper-grabbing conveyors. |
|
|
A production
test system for loudspeakers and microphones, testing frequency response,
distortion, and other parameters. The system had a highly flexible
interface for reference calibration and for configuring frequencies, levels,
pass-fail limits, test sequence scripting, and display format. |
|
|
A production
test system for complete functional test of a laser, detector, and
controller unit, including keeping track of serial numbers and to what point
each unit had been tested. |
|
|
A production
test system for an advanced chemical analyzer product that kept track of
pass-fail limits, serial numbers, lots, and yield and displayed and printed
neat charts of production statistics. |
|
|
A production
test system for an ionized gas generating instrument used in advanced IC
fabrication reactors. The system controlled a complex test station
containing many valves, flow controllers, sensors, and voltage outputs. |
|
|
A system for
characterizing stresses in a huge electric motor. Included 3-axis
control of rotor position, sweeping the 3 axes through steps in any nested
order, and display, saving, and recall of readings from multiple load cells
and magnetic flux sensors. |
|
|
A very large
LabVIEW program that acted as the "firmware" inside a commercial instrument
for measuring moisture content in gases. The program ran on a
single-board Pentium computer and managed a 40-panel user interface, each
with several functions, while
performing continuous data acquisition and curve fitting. |
|
|
A system that
listens for data from over 30 serial ports simultaneously and writes the
data to a multi-sheet Excel workbook. It included a flexible user
interface for laying out the spreadsheets and specifying the destination cells or
columns for each piece of data received. |
|
|
A sensor
monitoring system of over 100 channels with flexible strip chart display,
data save and recall, and flexible channel assignment. |
|
|
A multi-channel,
timed pattern of analog voltage sources with flexible pattern construction
and viewing tools. |
|
|
A factory
calibration system for a programmable voltage/current source commercial
instrument. |
|
|
Custom circuit
boards to enable the computer to measure and limit current draw on voltage
source lines. |
