摘要:
A sensor arrangement has a layer sequence that includes a holding substrate, an auxiliary layer, a detection layer and an insulating layer. The holding substrate holds detection elements. The auxiliary layer extends continuously over the detection elements or contains separate regions which are associated with a detection element. The detection layer has separate detection regions which are contained in a detection element and contain at least one semiconductor component which is sensitive to radiation. The insulating layer has separate insulating regions for electrically insulating the detection regions from a point of contact having electrically conductive connections and pads fitted on the free side. The pads are electrically connected to connecting points which are routed to the semiconductor components. This sensor arrangement can be used for detecting X-ray radiation and can be manufactured with particular ease.

In a projection arrangement with a projector and a deflecting mirror in which the image projection, proceeding from a projection direction along a principal projection axis impinges on the deflecting mirror which is supported so as to be movable in two spatial direction and whose mirror surface deflects a projected light bundle at an elevation angle and at an azimuth angle onto a projection surface standing on the ground the image projection is effected from the direction of a zenith at an angle &bgr; which is less than 60° in relation to a vertical line from the zenith and the deflecting mirror is arranged at the ground wherein the projected light bundle can be deflected toward the projection surface so that an image can be generated on the projection surface and moved on the latter.

A wind direction indicator for sailing vessels, particularly wind surfers or small yawls uses a weather vane pivoted to one end of an outrigger. The outrigger is to be fitted to the mid-height of the mast in the angle of vision of the yachtsman using a clamping device. In the case of a rotatable mast or a sail surrounding the mast, the outrigger can rotate in such a manner as a function of the sail position that the wind direction indicator is always on the windward side of the sail. Bearing aids for maintaining the best cruising course and a compass mounting support can be provided on the outrigger.

A radiation-receiving semiconductor component is specified. A semiconductor body is formed with silicon and has a radiation entrance surface and also an absorption zone. Electromagnetic radiation passes into the semiconductor body through the radiation entrance surface and is absorbed. The absorption zone has a thickness of at most 10 μm. A filter layer is formed with a dielectric material. The filter layer covers the radiation entrance surface of the semiconductor body. A potting body covers the semiconductor body at least at the radiation entrance surface thereof. The potting body contains a radiation-absorbing material.

A surface-mountable device (100) is specified, comprising a mounting side (101), a top side (102) lying opposite the mounting side (101), an electrically insulating carrier plate (1), an electrical component (2) and a housing (3). The carrier plate (1) terminates the device (100) toward the mounting side (101). Furthermore, the carrier plate (1) has a fixing side (103) lying opposite the mounting side (101). For the purpose of making electrical contact with the component (2), the carrier plate (1) has conductor tracks (4) arranged on the fixing side (103), contact areas (5) arranged on the mounting side (101), and openings (6), wherein in each case a contact area (5) is electrically conductively connected to a conductor track (4) by means of an opening (6). The component (2) is enclosed by the housing (3), wherein at least one opening (6) is arranged below the component (2). The housing (3) and the carrier plate (1) are arranged flush with one another in a plan view of the carrier plate (1). Furthermore, the housing (3) terminates the device (100) toward the top side (102).
