摘要:
A proximity sensor (12) is provided which has a magnet (16) and a sensor (18). The sensor (18) is oriented relative to the magnet (16)in such a way that the maximum sensitivity direction (E) of the sensor (18) is embodied substantially in parallel with the magnet axis (M) which extends through the poles (20, 22) of the magnet (16). In addition, an assembly (10) is provided.

A simple optical projection device with a high luminous efficacy has a point light source, a projection screen, a mask that is arranged in the light path upstream of the projection screen and is light-transmissive in some areas, and a light focusing optical lens arranged between the point light source and the mask. The optical lens is selected such that the prolongations of the emerging beams of the optical lens on the side thereof facing the point light source intersect in a virtual perspective center which is more remote from the lens than the point light source.

The invention relates to a radiation detection device (10) which comprises a carrier (12) having at least one pivotable section (16), a receiving unit (18), a drive (24), and an evaluation and control unit. The receiving unit (18) is arranged on the pivotable section (16), which can be pivoted together with the receiving unit (18) about at least one axis in relation to the carrier (12). The evaluation and control unit is connected to the drive (24) and the receiving unit (18), and the drive (24) is associated with the pivotable section (16). The carrier having the pivotable section is monolithically constructed.

The invention relates to a lens component of an optical rain sensor (10), comprising transmitter lens (16) designed as a Fresnel lens, and a receiver lens (18) designed as a Fresnel lens, both of which, in top view, have a rectangular contour having first edges, and second edges extending at a right angle thereto. The center point (M s ) of the transmitter lens (16) and/or the center point (M E ) of the receiver lens (18) is arranged eccentrically with regard to the lateral length of at least one of the edges (6), and the transmitter lens (16) and the receiver lens (18) are arranged side by side. The lens component (12) is produced using a molding process, in which a first and a second mold insert, each having a Fresnel lens shape, are arranged side-by-side, wherein the first and the second mold insert are arranged optionally rotated in each case by 0° or by 180°, and the mold inserts arranged in such a way form a negative form for the transmitter lens (16) and the receiver lens (18) of the lens component (12) during molding. In this way, a modular system for producing optical rain sensors (10) having lens components (12) is generated in a plurality of different configurations, which differ from one another with regard to the distance of the center points (M S , M E ) of the transmitter lens (16) and the receiver lens (18). In order to produce the lens component (12), the mold inserts are arranged optionally rotated in each case by 0° or by 180°, and are molded using a suitable plastic. This is done in a tool for producing a lens component (12) having a receptacle, in which the mold inserts can be placed next to one another along the second edge, wherein the first and/or the second mold insert, each rotated by 0° or by 180°, can be inserted into the receptacle (44).

The invention relates to a method for controlling an interior lighting system (25) in a vehicle (18), comprising a plurality of lighting means (26a - 26g) that can be controlled independently of each other. According to the invention, a moving light pattern, especially a wave light pattern, is generated depending on vehicle operating data by separately controlling the individual lighting means (26a - 26g), all lighting means (26a - 26g) being controlled with the same or similar light pattern, and the lighting means (26a - 26g) being controlled to generate the light pattern in a time-offset manner. The time-offset with which the lighting means (26a - 26g) are controlled depends on the speed of the vehicle.
摘要:
A capacitive sensor (20) and method for reading out a capacitive sensor field (2), wherein the capacitive sensor field (2) has a plurality of discrete electrodes (4) which are coupled to discrete supply lines (8). The supply line (8) of a first electrode (41) is routed such that it is capacitively coupled to at least one second electrode (42). A first signal (Cm1) is detected on a first supply line (8), which is coupled to the first electrode (41), and a second signal (Cm2) is detected on a second supply line (8), which is coupled to a second electrode (42). The capacitance (Cf1, Cf2) of the first electrode (41) or the second electrode (42) is determined by applying a predetermined calculation formula, which takes into account the first signal (Cm1), the second signal (Cm2) and the capacitive coupling between the second electrode (42) and the first supply line (8) coupled to the first electrode (41).
