<p>#CMT# #/CMT# The device (3) has a receiver (7) for receiving a signal having a frequency, and a transmitter (9) for outputting a signal having another frequency, where a microcontroller (11) manages the transmitter for communicating with an external electronic computing unit (5). An interference detection unit (13) detects a signal, and determines a value of a level of interference generated by the detected signal, where the device processes the value of the interference level, and manages the transmitter to communicate with the computing unit when the value exceeds a threshold value. #CMT# : #/CMT# An independent claim is also included for an electronic computing unit for a passive entry and passive starting system of a car. #CMT#USE : #/CMT# User identification device for a passive entry and passive starting system of a car (all claimed). #CMT#ADVANTAGE : #/CMT# The device processes the value of the interference level, and manages the transmitter to communicate with the computing unit when the value exceeds the threshold value, thus enabling analysis of the interference of noise produced by low frequency parasitic waves, so as to determine whether a signal emitted by the computing unit can be discriminated. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a passive entry and passive starting system for a car. 3 : User identification device 5 : External electronic computing unit 7 : Receiver 9 : Transmitter 11 : Microcontroller 13 : Interference detection unit.</p> |
