Mechanical Design: Based on some very aggressive requirements, Andrews-Cooper created an innovative mechanical design that enabled the mechanism to use one motor to both rotate and actuate the product consumable (breath cartridge). In addition to the breath cartridge, the rotational portion of the device was required to house the optical components including two PCAs, two lenses, two filters, and a light-tight enclosure. Andrews-Cooper designed the handle which contained a pressure transducer calibrated to measure air flow for obtaining a 3 Liter breath sample. (Note: the breath cartridge, not designed by Andrews-Cooper, obtains a sample by installing it into a handle from which a breath sample is extracted).
Electrical Design: Andrews-Cooper designed all the electronics in the handle and the device. This included all the motion electronics (motor control), a touch screen display, USB, battery power, and optics control and processing.
Firmware Design: Andrews-Cooper did all of the firmware associated with the parent device. This firmware also interfaced with a web portal for data storage. A-C created screen images and did the touch screen software.
