Technology Description:
UCI researchers have developed an antenna system that changes the nature of its transmission and reception of electromagnetic radiation based on local environmental conditions. It may use this feature to transmit local environmental information by wireless means without the need for power.

UCLA researchers have developed a novel logic style in which every logic gate consumes constant power independent of the input signal. It is called Wave Dynamic Differential Logic (WDDL) and is DPA resistant.

Together, Both antenna designs can be used for Smart Cards and RFID cards. Neither needs
external power source for responding to interrogation, and both provide security of transmitted data.

Advantages

• No external power source needed
• Automatic adaptation to ambient power environment
• Secure wireless transmission

Technology Bundling Project
Funded by Ewing Marion Kauffman Foundation and administered by Larta Institute, the Project’s expert panels examined technologies from 18 Southern California research centers and identified inventions which could be synergistically combined for unique solutions. These Linked-Solutions are now being offered for license, with reduced red tape and “1-stop technology shopping”.
