Access and communication using near ultra low energy fields

Abstract:

Use of a Near Ultra-low Energy Field (NULEF) communications as a non-radiating means of gaining entry to a car when the car owner is near the car or touching the car body avoids the use of problematic radio signals that may be intercepted by thieves. In addition, a NULEF communications system may be used as a high bandwidth in-car communication system using either NULEF-E or NULEF-H.
