AI Technical Summary

Benefits of technology

The technical effect that this innovation improves how vehicles can communicate with their control devices through an electronic system called Digital Switch (DS). It simplifies the process of acquiring data from sensing equipment on each car's wheelchair sensor. This makes it easier to develop more efficient cars while reducing costly components like those used at other parts of the world.

Problems solved by technology

This patented describes how current battery powered electric cars require high voltages (-120 V) that may damage their components or cause other issues such as overheating when they run at very fast speeds due to increased demand during peak hours. To solve these challenges, there has been developed a technology called Digital Acquire Module(DCM), where multiple analog sensors with varying levels of resolution and accuracy can be integrated onto one chip. However, DCM's use requires specific electronic devices like CPU cards and memory chips, making them difficult to change without increasing costs associated with each device being tested separately.
