Abstract: An intrusion detector with a plurality of reflector segments that focus infrared energy from a corresponding plurality of detection zones onto a common sensor. Uniform coverage of a rectangular area with detection zones and detection sensitivity unaffected by distance is achieved by means of a reflector segment arrangement in which the reflector segments are mounted on supporting structures and in which the distance from the sensor and therefore the focal length of the reflector segments is substantially proportional to the detection distance. The reflector segments are staggered horizontally and vertically on the supporting structures such that the centrally positioned reflector segments are set lower and have a different shape than the laterally positioned segments, and whereby the number of reflector segments is reduced with decreasing detection distance such that the density of the detection zones is uniform throughout the retangular protected room.

Date Jun. 15, 1989.An optical system for laser marking, such as for engraving marks such as numbers and dates on surfaces, and exhibiting improved efficiency and improved quality of the resulting mark. The optical system includes a focusing system, such as a lens, and a concave mirror situated between the laser and the mask with its vertex at the focal point of the focusing system and its reflecting surface facing the mask. An inlet opening in the concave mirror is formed about the vertex, and the transverse measurement of the inlet opening is slightly larger than the transverse measurement of the focal point. The mask is formed as a mirror, preferably a plane mirror, with the reflecting surface facing the concave mirror, and the radius of curvature of the concave mirror is longer than twice the distance between the mask and the concave mirror. In operation, the portion of the laser beam radiated through the mask is increased because the portion thereof not passing directly through the mask openings is reflected by the mirror face of the mask back to the concave mirror, which in turn reflects the light back to the mask, such that additional portions of the laser beam pass through the mask openings. The size of the reflecting surface of the concave mirror and consequently the amount of the light reflected by the concave mirror are optimized by the laser beam being focused by the focusing system in the small opening in the vertex of the mirror.

Abstract: A power supply is proposed for producing a regulated DC voltage from a mains AC voltage, which power supply has a mains transformer (10), a downstream rectifier arrangement (11) and a semiconductor element (13), connected in a DC voltage line leading away from the rectifier arrangement (11), which can be controlled as a function of a predeterminable nominal value (U2) and the actual value of the output DC voltage (Ua). The semiconductor element (13) is exclusively switched between the saturation and blocking state, a control device (16, 17, 19) which switches on the saturation state if the actual value is less than the nominal value and switches on the blocking state in synchronism with the mains AC voltage or the rectified voltage half-cycles derived therefrom, is allocated to the semiconductor element (13). The output DC voltage is applied to a capacitor (18) connected to the output of the power supply. Since the semiconductor element (13) is exclusively in the saturation or blocking state there is practically no power loss, or at least only an extremely small power loss, so that the power supply can be produced cost-effectively and with a small volume. <IMAGE>

Abstract: Methods for producing buried tunnel junctions in surface-emitting semi-conductor lasers and devices incorporating the buried tunnel junctions are disclosed. The laser comprises an active zone containing a pn-junction, surrounded by a first n-doped semi-conductor layer and at least one p-doped semi-conductor layer. In addition to a tunnel junction on the p-side of the active zone, the tunnel junction borders a second n-doped semi-conductor layer. For burying the tunnel junction, the layer provided for the tunnel junction is removed laterally in a first step using material-selective etching until the desired diameter is achieved and then heated in a second step in a suitable atmosphere until the etched region is sealed by mass transport from at least one of the semi-conductor layers bordering the tunnel junction. This enables surface-emitting laser diodes to be produced in high yields with stabilization of the lateral single-mode operation and high performance.

Abstract: The method relates to the protected transmission of data (D0-D4), the coding (‘S,’ ‘0’-‘F’) of which is represented, respectively, by a sequence (FR0-FR4) of a predefined number of on and off values (Z1, Z0). A count value (C) representing the predefined number is formed by changing the count direction (F, R) after each on value and incrementing or decrementing the count value with each off value. An error information (F1, F2) is generated if a first end value (EC), which is transmitted together with the data as a coded sequence (SIG) of the count value C, differs from a second end value (EC1, EC2), which, like the count value, is formed from the transmitted sequence. The method is advantageously used in identification systems (IS), in mobile data carriers (DT) and in read-write devices (SLG). This affords the advantage that a data transmission error can be detected quickly and with high reliability by using a simple forward and backward counter (CNT). The counter can be implemented with little circuit complexity by a simple software program or by an electronic circuit, e.g., by a binary cycle counter.
