Software/Hardware Design by TOS Systems

A single source for multi-discipline designs

Thank you for visiting the TOS Systems Inc. Software/Hardware design services page. TOS is located in the Wellesley Massachusetts area. We can provide on site consulting in the greater Boston area, or off site designs at our office. TOS Systems is a full-service engineering firm that offers a comprehensive set of system layout, hardware design, software engineering, product design, and project management capabilities.

TOS System's design capabilities include computer programming, embedded system design, firmware design, system design, digital design, analog design, electro-mechanical integration, air quality modeling and measurement, sensor design, transducer design, data collection design, telemetry design, and project management. We have moved many instruments through their complete development cycle from initial concept through design goal specifications, software/hardware design, prototype development, packaging, production, assembly, testing, certification, and documentation phases. The computer-controlled instruments we have helped develop include: extreme resolution auto-focusing scanning microscopes for the bio-tech industry, high speed CCD inspection equipment for the semiconductor and nanotechnology industries, automatic laser inspectors for the magnetic media industry, robotic handling systems for clean room applications, LED and laser triangulation based distance monitors for security systems, and environmental monitoring instruments for air quality.
