Firstly, the file for a wafer is generated, which holds at least the information of the size of the wafer, the position of a plurality of measurement pattern, the order in which the measurement patterns are captured and registered, and the alignment of the measurement pattern. Secondly, this information is stored in a master grid. Thirdly, images are acquired of the pattern of each position stored in the master grid of the generated file, wherein the image acquisition is carried out according to the order as stored. Finally, names are assigned to the acquired images.

Abstract: An apparatus determines an optimal antenna and frequency combination by selecting the optimal antenna from among a plurality, N, of antennas associated with a receiver and also selects the optimal frequency from among a plurality, M, of alternative receiving frequencies transmitted from a transmitter. This is achieved by determining all N×M possible antenna/frequency combinations, by determining the received signal quality at each combination, by comparing the N×M received signal qualities, and by selecting the one antenna/frequency combination having the optimal received signal quality.

Abstract: The invention relates to a method and an arrangement for generating positionally-accurate print images on a carrier material with the aid of an electrophotographic printer or copier. A positioning error of the position of the carrier material with respect to a toner image present on the toner image carrier is determined, which error occurs during the contacting of a carrier material to be printed. Dependent on the positioning error determined, for every subsequent contacting of the carrier material to be printed with the toner image carrier, the position of the carrier material with respect to the toner image is adapted before the contacting such that the carrier material and the toner image are arranged with respect to one another substantially free of positioning errors.

Abstract: The invention relates to a method for automatically finding an AM radio program, by which an AM radio receiver is tuned through in discrete steps, such that, for each set AM frequency, the reception quality at the currently set AM frequency is determined, the field strength of the neighboring frequencies is measured. If a significant field strength is detected at the neighboring frequencies, these are taken into account in determining the overall reception quality, in that the reception quality is reduced by a noise value, and subsequently the overall reception quality is compared with an upper quality limit. If the upper quality limit is exceeded, the program search is interrupted, and the AM radio program with this high overall reception quality is played. This method succeeds in reducing the number of misjudgments of AM radio programs with actually poor quality, and thus improves the reproduction quality of an AM radio receiver.

Abstract: Circuits generate an IQ voltage or current signal having orthogonal I- and Q-parts of approximately equal amplitude from an electric input signal having a frequency varying slightly around a carrier frequency, without needing a complex mixer. The circuit includes at least one ohmic resistance and at least one reactance connected in series (for a voltage) or in parallel (for a current). The reactance has an impedance at the carrier frequency approximately matching the resistance value of the ohmic resistance. The I- and Q-parts of the voltage signal are tapped as voltage drops across the resistance and the reactance. With two such series circuit branches in parallel, both voltage signal parts can be referenced directly to a reference potential, e.g. ground. The I- and Q-parts of the current signal are tapped as currents flowing through the resistance and the reactance. The circuit can be integrated at the output of a bandpass filter.
