Engineering and Product Development

Total Design LLC consists of a core team of highly experienced engineers that have a
proven 15 year record of working together to accomplish the completion of projects that
range from several thousand to several million dollars.

The group has combined professional experience in excess of 90 years. Accomplishments

include systems with analog signals such as, temperature, pressure, flow, and radiation and the

communication of these data to central computers using wired and wireless techniques.

Skills include:

Sensor use, design and development.

• Radiation sensors; Scintillation, Geiger, Semiconductor, Ion Chambers.
• Commonly used industrial sensors; temperature, pressure, distance, proximity and flow.

Signal conditioning and A/D conversion

• Current measurement down to femto amps level.
• Ten decade log current measurement.
• Differential and common mode.

Microprocessor embedded hardware and software design

• 32-bit, 16-bit, & 8-bit platforms (Intel, Motorola, uChip).
• High level software development in C, C++.
• Embedded real time operating systems and schedulers.
• Industry standard compilers, GNU, Keil, Borland.
• Customized logic design using standard ICs and PLDs.

Industrial communication networking and protocols

• Serial networks; RS232, RS485.
• High speed networks; Ethernet, ModbusTCP, DeviceNet, Profibus.

Industrial control applications including PLC, motor controllers, PID loop, stepper motor drives

PC Programming for data collection and display

• Visual Studio & Visual C++.
• Intellution visualization software.

System design and integration

Customer site support

• Installation, training, start up, & troubleshooting.

Schematic Capture

We draft electronic circuit schematics for electronics engineers who relay on us to enhance their

own circuit design by dovetailing the electronics schematics with the PCB layout and parts

procurement.

We draft electronic circuit schematics because there is strong demand from our customers.

Supposing an electronics engineer has completed their concept and logic of the design, including

components selection. they may need help in completing his schematics if they are in the form of

• CAE files which need more detail work before extraction of the Bill of material (BOM)
• and Netlist.
• Hard copy marked up with changes or
• Hand drawn diagrams.

If you require, we can complete your CAD schematics for you or go directly for PCB layout

design.
