• Designed laser scanner optics and managed the laser scanner compliance to the Bureau of Radiological Health regulations.
• Developed the optics, alignment procedures, and computer testing programs for the concave holographic grating spectro- colorimeter. This was the first stable colorimeter on the market, helping the company increase market share.
• Created the energy transfer optics for hazemeters, glossmeters, and colorimeters. In one case my design transferred over twice the optical energy to the detectors, allowing us to use less expensive parts and increasing the profit margin.
• Developed a patented fiber-optics ring illuminator for tristimulus colorimetery. This illuminator proved to be very reliable and cost effective.

• Designed interfacing circuits for computer-to-instrument communications and control. This allowed us to have a high profit add-on to existing instruments.
• Was project engineer for the CE certification of the Flo-System instruments. I was able to enhance these instruments with modifications that allowed us to get these devices certified and keep our European market open.
• Redesigned pc-board layout of op-amp circuits to help reduce RFI for CE compliance.

• Designed UHF receiver/transmitter circuits and boards to facilitate digital communications from underground devices to stationary vehicles. This addition to our product saved our customers man-hours and support costs.
• Created both active and passive RF circuits for amplification and filtering. In one case, my inexpensive filter design removed the problematic signals allowing our device to pass the CE tests.
• Developed antennas for UHF/VHF data links from manholes to stationary vehicles. These antennas were more effective and less expensive than off-the-shelf items.
• Performed EMC testing and redesign of microprocessor electromagnetic flow meters for CE compliance. The redesign was relatively inexpensive and allowed Marsh-McBirney to sell its premier flow meters in Europe.
