Elimination of dashboard reflections onto car windows - dashboard light is polarised by a filter or cap to reduce brightness

Abstract: Elimination of reflection into the windows from an illuminated dashboard of a motor vehicle which has illuminated instruments and windows in the driver's range of vision where part of the dashboard light sources has means to polarise the emitted light. The plane of polarisation is so chosen that the brightness of the light reflected from the window surfaces is as small as possible for the driver. A polarisation filter is fitted before at least one of the dashboard light sources or alternatively, a transparent cap, with light-polarising properties is fitted before one of the light source.

Remotely adjustable driving mirror for motor vehicle - has cable drives for tilt and inclination

Abstract: The driving mirror is mounted in special holders which allow it to swivel about a vertical axis and tilt about a horizontal axis. Two cable drives are provided, one attached to each holder with the operating ends of the drives mounted together on the dashboard. The driver is then able to adjust the mirror from the driving position. The design enables the drives to be looped around awkward body sections without design change. Also the nearside mirror is also fitted with controls in a simpler manner than would be achieved with rigid mechanical linkages.

Fail safe monitor for car lights - operates indicator if lights on during daytime or if on with ignition switched off

Abstract: The lighting circuit is fitted with a logic element with two main inputs One input is coupled to the ignition and the other to the lighting switch The output of the logic circuit operates a warning flasher on the dashboard if one input drops out, while the other is still on, ie if the headlights are left on with the ignition switched off A photocell is coupled to the circuit in such a way that the warning flasher operates if the car is driven without headlights in poor visibility, or with headlights in good visibility, thus saving battery drain as well as providing a fail safe headlamp monitor
