The present invention discloses a sample sorter system (1000) adapted to receive and sort samples (1500) according to predetermined criteria. The sample sorter system (1000) comprises a receptacle (1100) that is adapted to receive and retain fluid and samples (1500). The receptacle is operatively coupled with a drive (1400) and with a power source such that actuation of the drive causes the rotation of at least one circular component, which in turn causes the development of a flow regime in the receptacle such that the samples (1500) suspended in the fluid are conveyable along a closed path to at least one sample handling site (1101) that is positioned along said closed path.

The present invention concerns a method for constructing a light coupling system wherein a grating is manufactured on the surface of a multimode waveguide and defines the entrance of the waveguide for an incident light beam, said grating comprising a repetition of patterns. The grating is defined by a set of parameters comprising: • grating period (P), separating two adjacent patterns, • grating depth (d) between the highest and the lowest point of the pattern, • incident angle mean value (θ) of the incident light with respect to the waveguide. The method comprises a step of optimization of the set of parameters to obtain an optimized second set of parameters, in order to obtain a transmission efficiency (Ce) of the incident light into said waveguide for the first or the second diffractive order exceeding 35% for unpolarized light, or exceeding 50% for polarized light, at a given wavelength of the incident light.

A smart label is provided that can be affixed on or integrated in an object. The smart label is able to provide an electrical signal indicative of the applied pressure or force and/or the position of the applied pressure or force at a touch point on the object to which the label is affixed. The smart label comprises a layer structure (1) and a detector system (2). The layer structure (1) comprises at least a stack of a first, a second and a third layer (L1,L2,L3), whereby the first and third layers (L1,L3) each comprise a flexible, electrically conductive or semiconductive material and at least two electrodes (E) for connecting the layers to the detector system (2). The second layer (L2) comprises a flexible, deformable and compressible material and separates the first and third layers (L1,L3). The second layer (L2) is electrically nonconductive or electrically conductive but less conductive than the first and third layers (L1,L3). The at least two electrodes (E) from the first and third layers (L1,L3) are arranged along one side of the layer structure (1).
