PORTAL ACCESS CONTROL SYSTEM
First Claim
1. A method of automatically operating a portal by determining the intention of an approaching or receding carrier by providing a portable communication device for said carrier and a control (base) unit associated with the control system for said portal in which the antenna transmission and reception areas between specific events are varied either synchronously or independently to determine change in proximity between the control unit and the carrier as an indication of intent to open or close the portal.

Abstract
A combination of specific antenna type(s), with a system of specific antenna Rf field deployment, combined with the intelligent sensing of differing micro processor control of a digital antenna attenuator that controls disproportional attenuation (either synchronously or independently) of the transmission and reception areas of the antenna(e), of electronically paired devices, together with conditional time delays, is used to securely determine the ID and intent of an Rf access system user. A multifunctional remote device (condition unit) is carried by a carrier, the remote device transmits a short range radio frequency (Rf) signal which, when within range, is received by a stationary control unit. A second multifunctional remote device (cluster unit) is carried by the operator of the carrier and must be in secure communication with the condition unit to enable secure transmission between the control and the control unit. The operation of both said multifunctional remote units changes significantly with application in differing fields of use. By intelligently varying the interactive antenna Tx and Rx area, the proximity and therefore position of the remote (condition) unit to the base (control) unit can be deduced, outwardly appearing as a decoding of the intent of the carrier. This system can be implemented as a secure card-less RFID entry system for vehicle, building, border entry and mass transit systems.
