Automated Tester for Surgical Neuro-Monitoring

One of the other projects listed included developing some firmware and providing debug and verification support for a spinal surgery neuro-monitoring device. This project was to update an automated test platform for that device. The automated tester must be capable of accurately measuring stimulation currents, and providing a small analog signal output to test the acquisition inputs of the surgical device.

The scope of work included updating an existing design used for a previous generation product to be able to test the new device. While the core of the design was able to be re-used, there were significant changes to the testing requirements which required hardware, firmware, and software design changes. New, modular PCB’s were designed and new firmware packages were developed. Some of the functionality included embedded USB device implementation, peripheral simulation via UART, FPGA development, and ADC and DAC implementation.
