Benefits of technology

The invention relates to an improved way to measure pressures on surfaces that are used with electronic devices such as smartphones. This helps improve their performance and reliability over time without requiring expensive maintenance. It involves calculating specific functions based upon how well these sensors work properly when they're installed correctly.

Problems solved by technology

Technological Problem: Touch pads used on mobile phones often suffer from imperfections caused during manufacture due to variations in dimensions between individual components. This problem affecting accuracy makes it difficult to measure how well they work properly when pressed against them without causing errors.
