CASE STUDIES

Problem. Scope. Technology. Outcome.

Each example focuses on the engineering decisions and deliverables that moved the project forward—not unsupported marketing claims.

01

INDUSTRIAL IOT

Connected Industrial Monitoring Device

Challenge

An industrial team needed a field-oriented monitoring terminal that could collect equipment status and sensor data, then transmit it reliably through a cellular network for remote visibility.

Engineering Scope

  • System architecture
  • Electronics development
  • Embedded firmware
  • Sensor integration
  • Cellular connectivity
  • MQTT communication
  • Cloud integration
  • Prototype validation planning

Technologies

  • 4G / LTE
  • MQTT
  • Embedded MCU
  • Sensors
  • Cloud API
  • Device diagnostics

Prototype / Outcome

The work established an integrated prototype across system architecture, electronics, firmware and the communications path. It provided a testable basis for structured field validation, refinement and subsequent production planning.

02

ELECTRONICS REDESIGN

Legacy Industrial Electronics Redesign

Challenge

A proven industrial product depended on an aging control PCB and components that were becoming difficult to source. The replacement needed to retain required field interfaces without treating incomplete legacy documentation as a reliable specification.

Engineering Scope

  • Requirements reconstruction
  • Interface analysis
  • Component selection
  • Schematic design
  • PCB layout
  • Firmware adaptation
  • Prototype integration
  • Validation planning

Technologies

  • Embedded electronics
  • PCB design
  • Firmware
  • Power and signal interfaces
  • Test fixtures
  • System diagnostics

Prototype / Outcome

The engineering phase produced a functional replacement prototype, documented interfaces, reviewable electronics and firmware artifacts, and a validation path for the next build. Production release remained subject to the agreed verification program.

03

IMAGE PROCESSING

Weld Image Recognition

Challenge

A weld inspection workflow needed to highlight suspected defects in camera images, make detection results visible to an operator and provide interfaces to the surrounding production equipment. Original images and annotated results also needed to be available for review.

Engineering Scope

  • Industrial camera interfaces
  • Local image analysis
  • Object detection
  • Detection overlays
  • Operator review interface
  • Image and result storage
  • Review and annotation tools
  • PLC communication interfaces

Technologies

  • YOLO object detection
  • OpenCV
  • PyQt
  • Industrial camera SDK
  • Modbus TCP
  • Image annotation

Prototype / Outcome

The development work established a desktop inspection prototype with detection overlays, image review and saved results, together with camera and PLC interfaces. It provides a basis for site-specific validation of image acquisition, detection performance and equipment interaction.
