The present disclosure generally pertains to systems and methods for enabling leaf isolation in a multi-node tree network. Each sensing unit of the first element has two adjacent receiving coils. The mounting ribbon for the LEDs has a surface that is positioned adjacent an interior surface of the enclosure for transmitting heat from the plurality of LEDs to the enclosure. By incorporating the ferroelectric element in a field effect transistor structure, it is possible to realize a highly integrated semiconductor device for detecting reading or writing.
