Embodiment Construction

[0127] FIG. 1 shows a laboratory sample distribution system 100 . The laboratory sample distribution system 100 may be part of a laboratory automation system (not shown in detail) comprising one or more laboratory stations. Such laboratory stations may be, for example, pre-analytical stations, analytical stations and / or post-analytic stations. For example, they perform tasks such as analyzing samples, centrifuging samples, etc.

[0128] The laboratory sample distribution system 100 comprises a transport plane 110 below which a plurality of electromagnetic actuators 120 are arranged. Each electromagnetic actuator 120 has a corresponding ferromagnetic core 122. Electromagnetic actuators 120 may be arranged like a grid comprising intersecting lines or rows.

[0129]The laboratory sample distribution system 100 also includes a plurality of sample container carriers 130 . It must be noted that only one exemplary sample container carrier 130 is shown in FIG. 1 for the sake of cl...

Abstract

A laboratory sample distribution system (100) is disclosed. The system (100) comprises a plurality of sample container carriers (130), each being adapted to carry one or more sample containers (132), a transport plane (110) adapted to support the sample container carriers (130), a plurality of electro-magnetic actuators (120) stationary arranged below the transport plane (110), the electro-magnetic actuators (120) being adapted to move the sample container carriers (130) by applying a magnetic force to the sample container carriers (130), a plurality of inductive sensors (140) distributed over the transport plane (110), a control unit (160) configured to control the movement of the sample container carriers (130) on top of the transport plane (110) by driving the electro-magnetic actuators (120), and an evaluation unit (170) configured to linearize the out-put signal received from at least one of the inductive sensors (140) by means of a linearization algorithm, wherein the evaluation unit (170) is further configured to determine at least a distance between at least one of the sample container carriers (130) and the at least one of the inductive sensors (140) based on an output signal value of the linearized output signal value.

Description

technical field [0001] The present invention relates to laboratory sample distribution systems. The invention also relates to a method for operating a laboratory sample distribution system. Background technique [0002] Laboratory sample distribution systems are used in laboratory automation systems and include a plurality of laboratory stations, such as pre-analytical stations, analytical stations and / or post-analytical stations. A laboratory sample distribution system can be used to distribute sample containers between laboratory stations and other equipment. The sample container is usually made of a transparent plastic material or glass material and has an opening on the upper side. A sample container can hold a sample, such as a blood sample or other medical sample. [0003] A typical laboratory sample distribution system, calibration device and method for calibrating magnetic sensors is disclosed in WO 2011 / 138448 A1 or US 2016 / 0069715 A. As disclosed, the sample co...
