Inventor: ADLHOCH WOLFGANG W A
IPC: H04L9/32
Filed: 2005-12-07
Abstract: The invention of OPTICAL DIGITAL IDENTIFICATION is a process that consists of optically scanning a physical material, such as a plastic card or object, that is uniquely contoured by a means, transmitting and storing the obtained information and using it for comparison with new information, tested for a possible match. Due to the inferiority of accuracy repeatability in production equipment to measuring accuracy capability, the reproduction of the physical, unique and contoured original is impossible, and only the original can be used to produce a match with the previously stored information, which originates from the same original. Two practical applications would be it's use as identification cards or bank debit-credit card.

Such compositions are electrically non-conductive. Formulations containing nanoparticles (20) also show less phase separation of micron-sized particles (18) than formulations without nanoparticles (20). Methods for increasing heat transfer include using such compositions between heat producing components (12) and heat sinks (14).  Electronic components utilizing such compositions are also disclosed.
