Case Studies
We take client confidentiality seriously. Although we cannot share all of our projects due to NDA agreements, here are a few case studies to get an idea of our capabilities.
Conductivity Sensor
Challenge: Custom Conductivity and Temperature Sensor Circuit Card that optimized cost.
Action: Circuit card based on Analog Devices low power analog ARM microcontroller. Deliverables included:
-
System Architecture and requirement gathering
-
Proof of Concept prototype
-
Vendor management
-
Optimized low-noise analog circuit
-
Custom firmware in C
-
System verification testing
Results: Levels Successfully validated the design to be equivalent to the current sensing board while cutting 33% of the cost. The design will be incorporated into the next revision of their system.
Lithium Ion Smart Battery Charger Design and Verification
Challenge: A mission-critical system required a battery backup system to ensure the safety of the users.
Action: Prototyped using evaluation kits then transferred the design to custom printed circuit card. Designed an automated test system using Python and OTS Tools. Deliverables included:
-
System Architecture and requirement gathering
-
Proof of concept using evaluation kits
-
Schematic capture and layout using Altium
-
Vendor management for quick turn manufacturing
-
Automated test systems for battery life tests
-
Python Programming
-
Custom wire harnessing
-
Automation of test equipment
Results: Levels Successfully designed battery charging system through two iterations of the design. The design was validated using an automated test system.
Sports Therapy
Challenge: FDA notified the customer to make the product QSR compliant or remove the product from sales.
Action: Remediation of the design with changes to meet IEC60601 standards. Deliverables included:
-
Requirements documentation
-
Hazard analysis with controls
-
Schematic capture
-
Detailed design documentation including creepage and clearance
standards
-
Design changes to pass IEC60601
-
Design History File (DHF) management in accordance with FDA QSR
standards
Results: Levels successfully created design changes and technical documents to demonstrated the product is safe to use for sports therapy. The product continues to be a top-selling product in sports therapy.
