Patent EP-0322502-A2 (EP)
Inventor: RATHJEN DIRK DR DIPL-PHYS
IPC: G01S11/00
Filed: 1988-07-13
Abstract: Wave energy radiated or reflected by the target is received by means of a receiving arrangement made up of individual elements and is modulated onto light by means of an optical modulator arrangement of single-sideband modulators cascaded in the longitudinal direction. Apart from the bearing, the range to the target is to be additionally determined. The light wave field leaving the modulator arrangement produces the received wavefield in the correct phase with respect to its direction of incidence and curved wavefronts and is focused by means of a cylindrical lens arranged perpendicularly to the optical axis and to the longitudinal direction. Its focal length or the distance from a detector arrangement can be varied for focusing the image. Together with the offset of the image from the optical axis, they are a measure of bearing and range. There is no restriction with respect to the type of the received frequency so that the device according to the invention can be used both in sonar technology for very low-frequency received signals and in radar technology for very high-frequency received signals. <IMAGE>

Abstract: A system is described which determines the characteristics of a substantially rounded feature, such as via hole in a printed circuit board. The system includes an image scanner for providing a serial flow of a raster scan image of pixels which represent the rounded feature. Tangent detecting circuits are further provided which select groups (i.e., neighborhoods) of pixels from the scan image, each group including pixels clustered about a plurality of chosen azimuths and adjacent to a tangent to a boundary of the rounded feature. Processing circuits are further provided to trim each selected group of pixels to eliminate pixels not lying on the tangent line. The pixels which remain after the trim operation are representative of the limits (e.g., diameter, radius, etc.) of the rounded feature and enable an analyzing circuit to determine the characteris­tics of the rounded feature by examining the relationships between the tangent line pixels. 
     A second system is described which reduces the apparatus required for trimming the selected pixel groups. A tangent segment is fed into a plurality of parallel networks which initially identify right and left shoulders of the tangent segment. The identified shoulders are expanded and used as a mask on the original tangent segment to disconnect a central plateau thereof from its next lower and non-central plateaus. Subsequent trimming enables the central plateau to be identified.

Abstract: A high resolution, fully differential, CMOS comparator advantageously employs a single high gain, "folded cascode", fully differential operational amplifier (M1-M11) and an output latch (M15, M16) circuit and the output common mode control of the high-gain amplifier is implemented without requiring the use of a conventional control circuit, thus improving layout economy. The common mode control is performed by providing the latch with a differential input stage (M13, M14) through which a common mode feedback network is realized which acts upon a pair of output transistors (M10, M11) of the operational amplifier (M1-M11) for effectively controlling the output common mode thereof. The comparator has a simplified layout and is remarkably faster because it has not additional capacitances loading the outputs of the amplifier.

Abstract: The thermal flattening of grain oriented silicon steel which is in the semi-processed condition has improved magnetic properties after a stress relief anneal by using a low temperature and high tension flattening anneal. The flattening process is conducted at a temperature between 540 to 780°C (1000 to 1435°F) with a tension selected to produce a yield strength / tension ratio from above 5 to about 20 and preferably from 7 to 13. The yield stength of the material will vary depending on the length of the time at peak temperature but are typically from 2.8 to 28.1 N/mm² (400 to 4000 psi). The material as thermally flattened will have at least about10% stress. After a stress relief anneal above about 785°C (1450 °F), the material has significantly improved core loss compared to conventional thermally flattened material. The material is particularly suited for wound transformer core applications.
