#CMT# #/CMT# A capacitive windscreen (3) rain sensor has an oscillator circuit (41) inside the glass structure and second detector with a moisture-sensitive element comprising a temperature sensor (43) with common processors (42, 45) on the internal surface (2). #CMT# : #/CMT# Independent claims are included for procedures using the rain sensor. #CMT#USE : #/CMT# Capacitive windscreen rain sensor with internal condensation detection, e.g. for automatically actuating vehicle windscreen wipers. #CMT#ADVANTAGE : #/CMT# The internal temperature sensor allows the probability of internal condensation to be detected and so avoids spurious wiper operation. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing is a cross section through a windscreen with rain sensor. 3 : Windscreen 41 : Oscillator circuit 42 : Oscillator coupled circuit 43 : Temperature sensor 45 : Temperature sensor processor. |
