#CMT# #/CMT# The device (2) has an optical detecting unit (3) electrically coupled with a control unit (7) i.e. programmable control device. The detecting unit determines transparency of a window of a vehicle (1) and/or portions of the window. Optical information (8) and/or acoustic information (9) are/is output to a driver of the vehicle based on a predetermined threshold value of the determined transparency of the window. Operations of the optical detecting unit and the control unit are automatically activated with activation of an ignition of the vehicle. #CMT#USE : #/CMT# Device for outputting optical information e.g. warning signal and/or warning displayed, on a display unit, and/or acoustic information e.g. warning sound and/or language notification (all claimed), to a driver of a vehicle. #CMT#ADVANTAGE : #/CMT# The device detects contamination, freezing and fogging of the window or other visual impairments by determining the transparency of the window and/or the portions of the window and enables the driver of the vehicle to aware the impairments by outputting the optical information and/or the acoustic information based on the predetermined threshold value of the transparency of the window, thus preventing accidents. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic side view of a vehicle with a device for outputting optical and/or acoustic information to a driver of a vehicle. 1 : Vehicle 2 : Device for outputting optical an/or acoustic information to driver of vehicle 3 : Optical detecting unit 7 : Control unit 8 : Optical information 9 : Acoustic information. |
