Abstract: A method for creating or calculating panoramic images of the eye fundus particularly from images of a fundus camera. In the method a pre-positioning process is carried out in which a first variable is determined for geometrically associating the images with each other. An anchor image is determined as a reference for the first variables for the geometric association; areas that are associated with each other are determined in the anchor image and the other images by a block-matching algorithm; transformation parameters for a geometric transformation between the anchor image and the other images are determined from the mutual position of the associated areas; and the other images are transformed onto the anchor image by transformation parameters and are superimposed onto the anchor image and among each other.

Abstract: The present invention makes it possible to make high-quality recordings of the anterior and/or posterior segments of the eye as an individual image or also as a sequence of images without increasing the radiation load on the eye to be examined. In the method according to the invention, at least one pre-flash is used in order to determine an optimal exposure time for the main flash based on the recording of the pre-flash which is reflected by the object to be recorded. Both the pre-flash and the main flash are controllable and the recordings of the pre-flash and main flash are recorded with the same sensor of the electronic camera and are evaluated electronically by a control unit, and the recording of the main flash and, as the case may be, of the pre-flash is analyzed and/or corrected and displayed to the user.

Abstract: The present invention relates to a method for identifying an entity comprising placing an internal tag within the entity and placing an external tag proximate the entity wherein the internal tag and external tag are coupled.

Abstract: The invention relates to a method for determining and displaying medical informations, in which rough measurement data collected with the aid of different medical measuring methods in at least one measurement interval on the same test subject are stored and in which evaluation data are extracted from the rough measurement data. Further for generating medical informations for at least two selected measuring methods from among the different medical methods, the evaluation data extracted from the in each case associated rough measurement data of a measurement interval are interlinked and for the at least one measurement interval the linked evaluation data are processed as medical informations for outputting on a graphic output device. The invention also relates to an apparatus for performing this method.

Abstract: The present invention relates to a method for verifying concrete flexural strength by establishing a predictive correlation between concrete flexural strength and a second strength parameter, such as direct tension or indirect tension, measuring the value of that second strength parameter for a batch of concrete, and estimating the flexural strength of the batch by way of the second strength value and the correlation.
