Very soon, we will see a class of "secure keyboards" surfacing in the market."

Most people are familiar with resistors, inductors and capacitors which are three basic passive circuit elements. Using complex mathematics, Leon Chua in 1971 predicted the existence of fourth element which he named memritsor. Until recently, not many people knew how to make one. Senior Fellow R. Stanley Williams at HP has not only shown how to make one but also explains how it can be used in nano-circuitry in this article (Information Week"
