AI Technical Summary

Benefits of technology

This patented technology describes a new design for electronic components called TE (transmitting) modes used in communication systems such as radar devices or wireless communications equipment. These filters use special materials made from specific chemicals to absorb energy when they vibrate at certain frequencies. By compressively bending these materials around them, there will be strong connections between different elements inside the device without requiring any extra steps during manufacturing process. Overall, this innovation improves performance and efficiency while maintaining reliable operation over long periods of usage.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the performance of certain types of filters called TE MTM mode dielectrofilter(TMI). Specifically, current methods involve adding extra parts like springs or bolts to connect the inductor's terminals to the housing of the device. These connections may fail under extreme temperatures without being able to maintain their effectiveness over longer periods of operation. Therefore there needs improvement in these techniques to ensure reliable functionality across various operating conditions.
