The invention relates to an analysis system for analysing a sample on an analytical test element (16), said system comprising: a measuring module (13) for performing measurements of a sample on the analytical test element (16), an optical module (1, 25) comprising a lens (2, 26, 27), and a diaphragm (3, 21) for focussing the light. The lenses (2, 26, 27) and the diaphragm (3, 21) of the optical module (1, 25) are combined to form a multi-component injection-moulded part (23) embodied as a single component.

Analysis system for analysing a sample on an analytical test element

Der Verkehrsraum sowie der Fahrzeuginnenraum wurde in den letzten Jahren fur den Kraftfahrer zunehmend komplexer. Trotz einer sehr hohen Informationsdichte, muss der Fahrer die fur den Verkehr relevanten Objekte und Ereignisse rechtzeitig wahrnehmen, um sicher fahren zu konnen. Kleinere Fehler, sowie Unaufmerksamkeiten, konnen schwerwiegende Folgen mit sich bringen. An ausgewahlten Beispielen wird in der Arbeit Ablenkung im Strasenverkehr und deren Einfluss auf das Fahrverhalten analysiert. Nowadays drivers have to get along with an increasing complex visual environment in road traffic. There are not only distractions available within the vehicle, like radio, navigation system and passengers. The environment outside the car becomes also more and more complex. Car drivers’ gaze behaviour while being distracted is studied on the basis of some examples. Furthermore different performance indicators are analysed. Umfang: III, 176 S.

Ablenkung im Straßenverkehr und deren Einfluss auf das Fahrverhalten

A camera module (12) for a motor vehicle, comprising a lens assembly (20), a housing (22) having a back wall (32) and a front end (50) surrounding an opening (28), and an image sensor (24) carried by the back wall (32) and arranged within the housing (22) in or close to an image plane (A) of the lens assembly (20), said housing (22) comprising a lens holder (53) extending between the front end (50) and the back wall (32), said camera module (12) comprising a tube (26) which is fixed to the lens holder (53) at the front end (50) such that the tube (26) surrounds the opening (28) and extends from the opening (28) into the housing (22), wherein the lens assembly (20) is connected to a bottom end section of the tube (26) by a connecting means (71, 72), and wherein the thermal expansion coefficient of the tube (26) is higher than the thermal expansion coefficient of the lens holder (53), is characterized in that the connecting means (71, 72) extends over less than half of the axial length (hi,) of the lens assembly (20).

The device (1) has a carrier arrangement (5) holding an objective (2) to change a focal plane (11) relative to an optical component (6) e.g. charge coupled device chip. The objective is arranged in a section of a compensation body (7) that extends along an optical axis (10). The body is connected in another section of an arrangement of the objective with the carrier arrangement. The compensation body includes a material with a thermal expansion coefficient, which is measured such that a temperature-dependent change of the arrangement of the focal plane to the optical component is balanced.

Die Sichtweite beim Autofahren mit Abblendlicht ist durch die gesetzlich vorgegebene Lichtverteilung des Scheinwerfers begrenzt und haufig nicht ausreichend. Das Fernlicht kann bei der heutigen Verkehrsdichte nur selten eingeschaltet werden. Aktive Night-Vision-Systeme auf Basis der Infrarot (IR)-Beleuchtung bieten die Moglichkeit, die Sichtweite zu erhohen, ohne den Gegenverkehr zu blenden. Sie bestehen aus einem IR-Scheinwerfer, einer passenden Kamera und einem Mensch-Maschine-Interface (Display). Neben der Vorstellung des Systemgedankens werden im Folgenden vor allem die Moglichkeiten der Infrarot-Beleuchtung und Integration im heutigen Scheinwerfer diskutiert.

A camera optical system has a plastic lens (1) and an image sensor (4) mounted in a tube (2) that is longer than the focal length by a lower expansion coefficient holder (6) with tube thermal expansion coefficient chosen to compensate the movement of the lens focal plane due to temperature changes of the lens material. A camera optical system has a plastic lens (1) and an image sensor (4) mounted in a tube (2) that is longer than the focal length by a lower expansion coefficient holder (6) with tube thermal expansion coefficient chosen to compensate the movement of the lens focal plane due to temperature changes of the lens material. Includes INDEPENDENT CLAIMs for use of the holder to mount the image sensor and for use of retrofocus lenses.

The illumination unit (1) has an illuminant (10) and a main light exit opening (11), where the illuminant comprises a radiation area for emittable light, which is deflectable to the main light exit opening by a reflector (12). An anti-glare element (14) is arranged at the reflector for delimiting the radiation area. The reflector and the anti-glare element are integrally formed as functional element (16). A mounting body (22) is provided, on which the illuminant is arranged. The mounting body is formed as a cooling body.

The lens has optical functional zones (4-7), which are separated from one another by sectionally arranged transient areas (10). One of the edges (8, 9) for light absorption, light reflection and light direction, is arranged between the zones and between the transient areas. The transient areas are inclined to an optical axis of the lens, such that a light beam runs parallel to the transient areas. An independent claim is also included for a lighting unit for motor vehicle.

The device has a light source, a separation arrangement (7) for separating a spectral component of the light (4) emitted by the light source and a light conductor (6) for transmitting a visible part of the light emitted by the source to a light outlet point near a vehicle body opening. The separation arrangement and a second light conductor (8) are provided so that the defined separated spectral component (11) of the emitted light is passed via the second light conductor to a further outlet point.
