Title: Proceedings and device for the optical acquisition of the roughness profile of a material surface
IPC: G01B11/30
Filed: 1989-02-01
Granted: 1991-06-12
Abstract: A description is given of a method and a device for the indirect optical acquisition of the roughness profile of a material surface (10), in which method and device a light spot (14) is generated on the material surface (10) and the reflected light is fed to a light receiving arrangement (16). The reflection angle of the reflected light, and thus the respective surface inclination value, are determined for each scanned point of the material surface (10). The direction in which the light reflected in a scattered fashion is concentrated is formed in each case in order to determine the reflection angle. The desired roughness profile is subsequently reconstructed on the inclination values obtained.

Abstract: For individually controlling optical switches which are located in the optical path of light carrying useful signals and control signals, each optical switch in the optical fibre is preceded by an optical demultiplexer by means of which some of the light transmitted in dense wavelength-division multiplex with the light carrying the useful signal, carrying a control signal formed by means of a switch address and a switching command, is coupled out and supplied via an optoelectrical transducer to a decoder circuit which only allows the associated switching command to become effective at the associated optical switch when the switch address of this optical switch is received. The optical components can be combined on an IO chip on which an IC chip for the electrical assemblies is also mounted.

Abstract: For controlling the level of electrical signals a circuit arrangement is formed with two series connected amplifiers. A first amplifier containing a first variable resistor, operates at maximum amplification when a low input signal level is received. A second amplifier comprises a series connection of a second variable resistor and a current-controlled voltage source with two complementary outputs. The outputs of the voltage source are connected to a comparator and a controller with two separate outputs. One of the controller outputs transmits a control signal while the other output simultaneously transmits a blocking signal. A first output of the controller is connected with the first variable resistor, while a second output of the controller is connected to the second variable resistor.

Abstract: The present invention concerns a non-linear transfer function generator, e.g., for implementating "white stretch" of a luminance signal. Specifically, first (196) and second (198) emitter-follower amplifiers have their inputs coupled in parallel and their outputs coupled in series via first resistor (210) of a voltage divider. A second resistor (216) of the voltage divider is coupled to a point (218) of reference potential. A bias source is coupled to the second amplifier, e.g., via the second resistor of the voltage divider, so that the dynamic response of the second amplifier to an input signal is limited with respect to the first amplifier. The output signal of the first amplifier is linear and an output signal developed at the output of the second amplifier is non-linear. The linear and non-linear output signals are combined by a current steering network (188) in response to a control signal (Vc) representative of a characteristic of a processed version of the luminance signal.

Abstract: The object is to specify a switched-mode power supply having n separately current-limited output circuits, whose device for monitoring the currents flowing in the individual output circuits can be implemented using components which are as simple as possible and operate with as little loss as possible. This object is achieved in that, in the case of (n-1) output circuits, current transformers (SW) are used in each case for current detection both for the primary circuit (lacuna), while the current flowing in the n-th output circuit, that is still missing, is detected in an evaluation circuit by a calculation on the basis of the electrical variables obtained by means of the current transformers (SW). <IMAGE>

Abstract: The invention relates to a method for the production of rotationally symmetric bodies by atomising a metal melt, collecting the resulting metal droplets on a rotating surface, the surface being completely covered with metal droplets after one complete revolution, continuing to move the surface, while maintaining the rotation, out of the collecting position or plane of atomisation. In order to improve known methods in such a way that the body produced has as uniform a diameter as possible over its total length, it is proposed that the position of the plane of atomisation be determined continuously during the feed of metal droplets and the speed of movement of the surface and/or the mass flow of the metal droplets be controlled so that a predetermined ideal position of the plane of atomisation is maintained.

Abstract: This invention relates to an arrangement for efficiently transmitting facsimile signals from a facsimile source to a facsimile destination using a standard facsimile user interface. The connected switched communications network recognizes that the call is from a facsimile source or to a facsimile destination and causes the facsimile signals to be transmitted at the transmission speed of the source to storage in a network. Subsequently, the signals are transmitted from storage to a facsimile destination at the transmission speed of the destination when the destination becomes available. Advantageously, the source need not wait for the destination to become available before transmitting, and the transmission can take place at a bit rate that matches the source and the destination even when these bit rates are different. Retransmission because of errors in one link is only required for that link, i.e., from the source to the storage or from the storage to the destination. Advantageously, this is accomplished without changing the very simple user interface of prior art facsimile transceivers.

Abstract: In a sampled data transmitting apparatus in which the sampled data to be transmitted are divided into odd-numbered samples and even-numbered samples and arranged in different rows of a two-dimensional data array, and in which error correction codes are annexed to each row and to each column of the two-dimensional data array, the row arraying sequence in one of the odd-numbered or even-numbered rows is caused to differ from the row arraying sequence in the other of the odd-numbered or even-numbe red rows so that odd-numbe red data and even numbered data continuous with the odd-numbered data are not arranged in one row. In this manner, even when the error correction becomes unfeasible by the error correcting code for one row, interpolation becomes feasible because there exist no odd-numbered data or even-numbered data continuous to each other in the row.
