The invention relates to a laboratory instrument comprising a network interface apparatus ( 6 ), which is configured to provide, in the inserted position of the insertable instrument, a data connection between at least two network instruments of a laboratory instrument network ( 100 ), which network instruments are taken from the group of network instruments including at least a first control apparatus ( 4 ) of the laboratory instrument and the at least one insertable instrument ( 20; 30 ). The invention further relates to a laboratory instrument network including the laboratory instrument and a method for working on laboratory samples using the laboratory instrument network.

The invention relates to a pipette auxiliary system for supporting manual pipetting or dispensing of a plurality of samples of a sample-holding arrangement, in particular a microtiter plate. The pipette auxiliary system according to the invention supports the manual pipetting or dispensing of a plurality of samples in a working position of a sample-holding arrangement, the pipette auxiliary system comprising: a base apparatus comprising a positioning device which is designed to position the sample-holding arrangement in the working position inside a positioning space of the base apparatus, said positioning space being opened at least along a plane for the pipetting; the sample-holding arrangement which has a plurality of sample holders; a measurement arrangement comprising a plurality of measurement elements which are positioned at least in the working position underneath this plane and using which the occupancy state of at least one sample holder can be detected in the working position; and an output device or a light arrangement using which the sample-holding arrangement can be illuminated in accordance with this occupancy state of this at least one sample holder.

An electronic laboratory metering system for liquids includes an electrical hand-held metering device ( 2 ) having at least one operation sensor unit ( 5 ) that detects operation of the hand-held metering device ( 2 ) and generates operating data and stores same in a storage apparatus ( 6 ), wherein the hand-held metering device ( 2 ) has an interface module ( 7 ) for connecting the hand-held metering device ( 2 ) to an external network access apparatus ( 4 ) for transferring the operating data; the metering system ( 1 ), specifically a data processing system ( 3 ), has a comparison unit ( 9 ) to compare operating data with target operating data and/or to compare context parameter data from the context parameter sensor unit ( 8 ) with target context parameter data and to generate a comparison result. The metering system ( 1 ) includes a documentation unit ( 10 ) designed to generate and store log data records including at least the operating data and/or the context parameter data. The documentation unit ( 10 ) is connected to the comparison unit ( 9 ) to transmit the comparison results from the comparison unit ( 9 ) to the documentation unit ( 10 ) and the documentation unit ( 10 ) stores the comparison results as part of the log data records to be assigned to the relevant operating data and/or context parameter data, to add to same after operation of the hand-held metering device ( 2 ) has ended.

A computer implemented method for determining a first value of at least a camera parameter of a camera, the method comprising at least the steps of accessing a first image captured by the camera, wherein the first image displays a scene and comprises a first set of pixels, and wherein the scene comprises a first scene region, the first scene region being displayed in a first image portion of the image and generating, for each pixel of the first set of pixels, a respective first data item associated to said each pixel, wherein said respective first data item comprises respective position information associated to said each pixel, said respective position information being indicative of the position in the first image of said each pixel with respect to the location of the first image portion in the first image and determining the first value of the camera parameter by using at least a first plurality of pixels of the first set of pixels, wherein, for each pixel of the first plurality of pixels, the respective position information associated to said each pixel fulfils a first condition.

Computer implemented method for calibrating ( 216 ) an optical recording device ( 150 ), the optical recording device ( 150 ) being associated with a field of view and an image plane, by using at least a model panel ( 140 ), the model panel ( 140 ) comprising a set of calibration indicia ( 40 - 49 ), and a first calibration view, wherein the first calibration view comprises a first set of calibration locations ( 20 - 29 ) of the field of view, wherein the method comprises at least the steps of constructing ( 204, 207 ) at least a plurality of scenes so that, for each location of the first set of calibration locations ( 20 - 29 ), a calibration indicium of the set of indicia is located in a respective scene of the plurality of scenes at said each location, and wherein each scene of the plurality of scenes is constructed by translating the model panel ( 140 ) to a respective position with respect to the optical recording device ( 150 ); acquiring ( 205, 208 ) at least a plurality of images ( 920, 930 ), so that each scene of the plurality of scenes is displayed in a respective image of the plurality of images ( 920, 930 ); locating ( 206, 209 ) at least a plurality of calibration loci ( 60 - 69 ) so that, for each location of the first set of calibration locations ( 20 - 29 ), a respective locus of the plurality of calibration loci ( 60 - 69 ) is comprised in a respective image of the plurality of images ( 920, 930 ), said respective image displaying a respective calibration indicium and said respective calibration indicium being located at said each location and being displayed in said respective locus; and calibrating ( 216 ) the optical recording device ( 150 ) by using at least the loci of the plurality of calibration loci ( 60 - 69 ) as locations in the image plane of the projection onto the image plane of the first calibration view.

A measuring apparatus usable in a liquid handling apparatus, and method, for detecting a deformed pipetting container using a first and a second measuring device, the measuring apparatus being configured to determine the position of an end region of the pipetting container as a f unction of a position of a measurement support section of the pipetting container as relative position data in a data storage device, so that subsequently the position of the end region of the pipetting container can be determined by measuring the position of the measurement support section and from the relative position data.
