Case Study: Obturation Device

Obturation Device used by endodontists during root canal procedures.

Working closely with our client’s mechanical and industrial design teams, Pentad Design developed the hardware and firmware for an obturation device used by endodontists during root canal procedures.

The Dental Device synthesizes complex stimulus output waveforms, synchronously alt tagreads back the response waveform then rapidly executes customized algorithms to present a real-time display. The DSP also handles keyboard scanning, CAN bus, LCD panel, timers, power management, audio output, user Interface, and communication with a PC.

Embedded Software/Firmware Design Services

Pentad Design develops creative embedded software solutions for clients in the medical, aerospace, industrial, and consumer electronics industries. Our engineers have many years of experience and our hardware and software teams collaborate early in the development process to create an integrated design to meet your strategic objectives.

We can quickly develop your product to the prototype stage or take it all the way to the final manufacturing stage inclusive of any test development that may be needed along the way.

Our background and experience with many diverse industries enable us to work within your quality system requirements.
