The following is only a sample of work done.
Fuel Cell Test Stand
Designed an Automated PEM Fuel Cell Test Stand based on a realtime open source OS.
Mining Industry Instrumentation
Designed a prototype Digital Inclination Probe for hard rock borehole drilling in the mining industry. Design specifications required included high accuracy, repeatability, work in harsh environments, work in an environmentally friendly manner, and determine drilling angle in a speedy manner.
This instrument was an embedded microprocessor controlled instrument that accessed high accuracy & high precission gravimetric sensors mounted on a printed circuit board to be inserted in a 26 mm diameter steel drill pipe. It was designed to operate in harsh environments including rough handling and a wide range of temperatures (-40° C to +55° C).
The requirement for environmental friendliness was achieved as the traditional instrument in this industry made use of vials of acid etching the glass vial to indicate drill angles. The disposal of the use-once vials created environmental hazards. This was replaced by the microprocessor based instrument.
A handheld instrument was developed to transmit the result from the instrument through the use of electromagnets.
This prototype was developed into a product line which served in various hard rock drilling from diamond mines in Nunavut to gold mining in central Quebec to use in hard rock drilling in dessert environments in the US South West.
The instrument helped reduce measurement time from 10-15 minutes to 30 seconds. When one is being paid by the foot drilled, time is money.
Material Testing Field
Designed a linux-based complex waveform generator for advanced material testing, thus allowing the experimenter to feed in complex waveform spectrum loading such as Turbistan, Falstaff and other custom defined load spectrum waveforms. This software based waveform generator was written in C and made use of Linux-based Comedi (linux control and measurement device interface) open-source software project.
Follow on contract expanded the functionality of the complex waveform generator. Added modules to communicate with external hardware through IEEE-488 GPIB interface. This was accomplished by making use of the Linux-GPIB open-source software project.
Diamond Sorting Machine
Designed a printed circuit board using manual interface control to adjust the level of vibration used to sort diamonds on a vibrafeeder. The control process involved an embedded microprocessor.
Developed a National Instruments LabWindows application for data acquisition/measurement and analysis of an asphalt test comducted on a servo-hydraulic material tester.
Worked on a computer based, cableless helicopter landing system. The solution involved a multi-camera VME-based realtime computer system that provided visual signals back to the helicopter pilot for landing on the deck of a ocean-going vessel in calm to moderate level seas.
