    Abstract: An apparatus comprising at least one measuring cell (10) is disclosed. The measuring cell comprises a first cavity (16 and a second cavity (18) perpendicular to the first cavity, the first cavity and the second cavity comprising an overlap at first respective ends and a reflective surface (20) at the opposite respective ends. A beam splitter (15) is located in the overlap and an electromagnetic radiation source (12) is arranged to project a beam of electromagnetic radiation onto the beam splitter (15) such that the beam is projected into each of the cavities. A phase detector (22) for detecting a phase difference between the respective electromagnetic radiation reflected by the first and second cavity (16; 18) is also provided. In addition, the apparatus has a fluid channel (26), at least a part of which runs parallel to the first cavity (16) such that the electromagnetic radiation projected into the first cavity extends into said part of the fluid channel. This allows for the interferometric detection of particles in the fluid channel.

    Abstract: A lighting system for exterior lights of an automobile comprises a first lighting unit (10,12,14,16) primarily for outputting a first automotive light signal and a failure detection system (26) for detecting a failure of the first lighting unit (10,12,14,16). A second lighting unit is primarily for outputting a second automotive light signal. The second lighting unit comprises an LED light unit. A controller (30) is adapted to determine if there is failure of the first lighting unit, and if there is failure of the first lighting unit, to use the second lighting unit to generate the first automotive light signal. This is in response to an output request from the first lighting unit (10,12,14,16).

    Abstract: A method of determining the ageing characteristics of an LED comprises applying a current stress pulse to the LED. The LED is monitored to determine when the thermal heating induced by the current stress pulse has been dissipated to a desired level. The operational characteristics of the LED are then measured before applying the next stressing pulse.This method accelerates the effect of aging in a reproducible way and therefore is able to greatly reduce the time needed for a reliability test.
