Starting a project is all about understanding: understanding Concept of Operation, use cases, mandatory features, optional features, schedule constraints, cost constraints. With the end-goal clearly in mind, the Fourth Dimension team can begin to evaluate feasibility, brainstorm potential solutions, identify hardware designs and code that can be re-used, find the risk areas and begin developing risk mitigation tactics.
Knowing what needs to be created evolves into how it’s going to be created. Starting with high-level system designs and functional architectures, the team iterates through spins of the design. The team works to arrive at an answer that balances all of the competing cost, schedule and functional components. The high-level design is broken down and further iterated into peer-reviewed, detailed designs.
Machining metal, fabricating and assembling PC boards, developing software; during the development phase the Fourth Dimension team brings the design to life. The engineers create and integrate the components to produce a prototype system. The test team performs extensive testing of the prototype to determine functional and environmental performance.
Prototyping and testing yields to design tweaks, software changes and finally fabrication and assembly of deliverable systems. More testing; burn-in, production, QC making sure that the product we deliver works as expected right out of the box.
Think of the PC board as the engine of the system. Pull out the engine and the system is just a paperweight.

- Tooling design
- Thermal & structural analysis
- Environmental and Reliability testing
- CAM, CNC machining, molding and vacuum casting
You built the electronics and put it in a great package. Maybe it should actually DO something. This is where software comes in to save the day.
Fourth Dimension software engineers are experienced with many different microprocessor platforms, ranging from 8-bit micros running basic applications to 32-bit micros running Linux. Our specialists can integrate sophisticated video and audio algorithms into DSP devices to support enhanced user experiences. Our engineers develop devices implementing a wide range of communication protocols: USB, Ethernet, UART, SPI, I2C, and RF including Bluetooth ®, Bluetooth Smart (BLE), ZigBee ®, WiFi, cellular and custom RF protocols.
Our embedded software team works as an integrated member of the project team throughout the entire development to help define feature requirements and create system architectures. The embedded software team provides test code used by the hardware design team to verify PCB designs and by system testers to verify in system operation.
