Abstract: An ion-sensitive sensor arrangement includes: a semiconductor chip having a first surface, which has a media-sensitive region and at least one, first, electrical contact surface; and a support having a second surface, which faces the first surface of the semiconductor chip. An opening is provided, which aligns with the sensitive region, and at least one, second, electrical contact surface, which overlaps, or aligns with, the at least one, first, electrical contact surface. Between the support and the semiconductor chip, a preferably elastic, anisotropic conductor is arranged, which produces a conducting connection between the at least one, first, contact surface and the at least one, second, contact surface, and which has a traversing opening, which aligns with the opening, so that the sensitive region of the semiconductor chip can be contacted through the opening by an analyte. The preferably elastic, anisotropic conductor seals the region outside of the opening against contamination with the analyte.

Abstract: The aim of the invention is to adjust the operating point of a laser that can be modulated by a data signal. The operating point of the laser is adjusted by regulating a direct current flowing through the laser; whereby said direct current correlates with the optical characteristics of the laser. In order to carry out said adjustment, the direct current is controlled above an alterable threshold current. A differential current defined from the difference between the direct current and the threshold current or a variable correlating with the differential current is adjusted to a constant value or one that is solely dependent on temperature for the adjustment of said operating point.

Abstract: A sighted device has a sight that includes an objective lens lying on an optical axis of the sight so that an input beam is coincident with the optical axis, an eyepiece lens lying on the optical axis, an imaging detector having a detector output signal, a signal processor that receives the detector output signal from the imaging detector, modifies the detector output signal, and has a processor output signal, and a video display projector that receives the processor output signal and has a video display projector output. An optical beam splitter lies on the optical axis. The beam splitter allows a first split subbeam of the input beam to pass to the eyepiece lens and reflects a second split subbeam of the input beam to the imaging detector. An optical mixer mixes the first split subbeam and the video display projector output prior to the first split subbeam passing through the eyepiece lens.

Abstract: An illuminated target structure for viewing a scene includes a transparent medium having a transparent-medium peripheral rim and a light-reflective target within a transparent-medium central region. A circumferentially uniform ring illumination source is in contact with the transparent-medium peripheral rim. The ring illumination source projects a substantially uniform illumination into the transparent-medium peripheral rim and thence onto the light-reflective target. The ring illumination source preferably is a modified optical fiber structure having a modified lateral surface in facing relation to the transparent-medium peripheral rim and having a light leakage through the modified lateral surface. An image intensifier may be positioned in facing relation to a transparent-medium front face.
