Abstract: An optical module has a lens holder with a lens assembly of, for example, three lenses and a diaphragm. The lenses and the optional diaphragm are unequivocally oriented by the geometrical form thereof such that no other optical adjustment is required. The optical module has a specially embodied circuit carrier with a thin region and a thick region that holds the thin, relatively sensitive region as in a frame, the thin region preferably carrying a semiconductor element. Along with the particularly low tolerances between the semiconductor element and the lens unit, the invention advantageously enables a more reliable assembly (e.g. soldering, gluing, etc.) of a semiconductor element, for example in flip-chip mounting technology, on a thin and thus relatively stable, flat plane, than comparable assembly processes of components on exclusively flexible circuit carriers. The optical module is particularly suitable for interior and exterior applications on motor vehicles.

Abstract: An optical module has a lens holder into which a lens array with three lenses and a diaphragm, for example, is inserted. The lenses and the diaphragm are oriented by way of the geometrical shape thereof such that no further optical adjustment is required. The circuit carrier and the lens unit are adjusted via at least one permanently flexible or springy element which is disposed between the lens holder and the circuit carrier and presses the component-equipped area of the circuit carrier away from the lens holder and against at least one stop element that is in positive contact with the lens unit. In the novel optical module or optical system it is no longer necessary to take into account the thickness tolerance of the circuit carrier and possible adhesives in the tolerance chain of optical modules. The module and the system are particularly suitable interior or exterior zone applications in motor vehicles.

Abstract: An optical module has a circuit carrier, a housed semiconductor element placed on the circuit carrier, and a lens unit for projecting electromagnetic radiation onto the semiconductor element. The lens unit, which is constructed separate from the cased semiconductor element, preferably comprises a lens assembly formed of, for example, three lenses and of a diaphragm. The three lenses, optionally together with the diaphragm, are aligned in a well-defined manner due to their geometric design so that no additional optical adjustment is necessary. According to the invention, a support is formed, at least in sections, on the case of the semiconductor element, and the lens unit is placed thereon thus being supported. The concept is that by forming a support directly on the case of a cased semiconductor element even with classically cased semiconductor chips, it is possible to construct a camera module with which every mechanical focus setting can be eliminated.

Abstract: An optical module has a lens holder into which a lens array formed of three lenses and a diaphragm, for example, is inserted. The lenses, and optionally the diaphragm, are clearly oriented by way of the geometrical shape thereof such that no further optical adjustment is required while the lens array is disposed in a supported manner directly on the sensitive surface of the semiconductor element. A camera module can be designed which dispenses with the need to mechanically adjust the focus in any manner by supporting especially the lens holder or the lens or the peripheral area thereof directly on the chip surface. The optical module is particularly suitable for applications in the interior or exterior zone of a motor vehicle.

Abstract: The invention relates to a method and a device for detecting an object or a person (2), especially in a motor vehicle (1), using at least one illumination unit (3) which emits light pulses (4) for illuminating an image region (5) to be examined, and an image recording unit (6) comprising at least one image sensor (7) that receives light pulses reflected by an object (2) or a person in the image region and records the image information of the object (2). At least one illumination unit (3) is arranged in or on the motor vehicle (1) in such a way that it is spatially separated from the image detection unit (6). The invention is characterised in that one unit (6 or 3), out of the separated illumination unit (3) and the image recording unit (6), emits control light pulses (10) for the synchronisation or control of the units (3; 6) by means of a light wave emitter (8), and the other unit (3 or 6) receives the control light pulses (10) by means of a light wave receiver (9).

Abstract: The invention relates to an electrical device for that features a cup-shaped housing to accept a circuit carrier (4) with a front side insertion opening. The circuit carrier (4) features a connector (5). the insertion opening is sealed by a sealing part (2 and/or 3) that features a cutout for the connector (5). The sealing part (2 and/or 3) is connected by a mechanical hinge to one side of the insertion opening of the housing. To seal the insertion opening the sealing part (2 and/or 3) is hinged over the insertion opening, whereby location elements (8) engage into cutouts (9) of the lower part of the housing (1). The cup-shaped housing of the electrical device in accordance with the invention thus only has one open side.

Abstract: An anti-theft device for a motor vehicle includes a key having a transponder. A lock has a keyhole for receiving the key. An antenna is in the vicinity of the lock. A control unit for controlling the antenna sends starting signals to the transponder and receives answer signals from the transponder. An assembly is turned on or off if the answer signals correspond to set-point signals. The antenna has a lighting device being controlled by the control unit for illuminating a region around the keyhole, at least before the key is inserted.
