A system includes an optical fiber embedded in a windshield. The system includes a reflector embedded in the windshield and oriented to reflect light to a first end of the optical fiber. The system includes a sensor oriented to receive light from a second end of the optical fiber.

The present invention relates to a rain sensor detecting the size of rain drops based on optical effects. The rain sensor is mounted on a first surface of a pane in order to detect the amount of moisture on an opposing second surface of the pane. The rain sensor comprises at least one emitter for emitting electromagnetic radiation, directed from the first surface to the second surface to form at least two rain-sensitive areas on the second surface At least one receiver is included for sensing radiation emitted by the emitter and that has been internally reflected at the rain-sensitive areas. The rain sensor generates an output signal indicative of an amount of moisture on the rain-sensitive area. A control unit calculates a minimal droplet size based on the output signal.

A laminated glass pane having a sensor assembly is presented. According to one aspect, the laminated glass pane has a first and a second glass layer that are connected via a combination film, and the sensor assembly is at least partially situated between the first and the second glass layers. According to another aspect, the sensor assembly includes a receiver antenna for supplying electromagnetic power to the sensor assembly and a transmitter antenna for transmitting information of the sensor assembly to a receiver unit situated outside the laminated glass pane. The sensor assembly includes a sensor and an evaluation unit that evaluates information from the sensor for transmission by the transmitter antenna.

A component for the production of a laminated sheet, includes at least two electrical functional elements and cabling, which includes electrical conductors having insulating sheathing and connected in each case to an electrical functional element, wherein the cabling has a bundling section, in which all the electrical conductors are surrounded by a common insulating sheathing.

An optical sensor device for the detection of ambient light is adapted to be coupled to a pane (10), in particular to a windshield of a vehicle. The optical sensor device has a sensor unit which includes at least one light receiver (22) for ambient light and a lens plate (12) for directionally coupling an ambient light beam (26) out of the pane (10) onto the light receiver (22). The lens plate (12) has a surface (18) facing the light receiver (22) and oriented substantially parallel to the pane (10) in the coupled condition of the optical sensor device. The surface (18) includes a prism structure (20) having a plurality of single prisms (24) which are designed to direct the rays of a specific ambient light beam (26) defined by a principal direction (A) and an aperture angle onto the light receiver (22).
