The device comprises a conformable substrate which is primarily composed of a flexible and stretchable polymer, and a plurality of flexible electrodes and conductive leads embedded in the conformable substrate. Not only the substrate, but also the leads are stretchable. The substrate may consist of PDMS, and the leads may consist of a conductive PDMS, in particular, PDMS with an electrically conductive filler material, and may optionally be metal-coated. The device defines a multi-electrode array which may be employed for neurostimulation in the epidural or subdural space of an animal or human.

Abstract: The present invention describes methods and apparatuses for creating superposition shape images by superposed base and revealing layers of lenslet gratings. The superposition shape images form a message recognizable by a human observer or by an image acquisition and computing device such as a smartphone. The superposition shape images may be created by different superposition techniques ranging from 1D moiré, 2D moiré and level-line moiré superposition techniques to lenticular image and phase shift superposition techniques. Moiré superposition techniques enable creating superposition shape images at different apparent depth levels. Applications comprise the protection of documents and valuable articles against counterfeits, the creation of eye-catching advertisements as well as the decoration of buildings and exhibitions.

Abstract: The disclosed invention describes a new apparatus performing a new data acquisition for quantitative refractive index tomography. It is based on a linear scanning of the specimen, opposed to the classical approaches based on rotations of either the sample or the illumination beam, which are based on the illumination with plane waves, which orientation is successively modified in order to acquire angular information. On the contrary, the inventive apparatus and method rely on a specially shaped illumination, which provides straightforwardly an angular distribution in the illumination of the specimen. The specimen can thus be linearly scanned in the object plane in order to acquire the data set enabling tomographic reconstruction, where the different positions directly possess the information on various angles for the incoming wave vectors.

Abstract: The invention refers to a method for analyzing reflected light of an object. First a light angle distribution for a point of the object is determined. Then a plenoptic projector is controlled to illuminate the point of the object with the determined light angle distribution. Then the reflected light intensity of the point of the object is measured and the measured reflected light is analyzed in dependence of the determined light angle distribution.

Abstract: A power flow control system for an interconnected power system, the interconnected power system comprising a plurality of electrical subsystems; an abstract framework configured to work as a utility maximizer under constraints (that applies to the electrical subsystems by specifying their capabilities, expected behavior and a simplified view of their internal state); and a plurality of agents. Each agent is responsible of one or a plurality of the electrical subsystems, comprises means configured to express an internal state of the electrical subsystem within a common system of coordinates, and has communication means configured to communicate among agents according to a protocol. The abstract framework means enables a composition of a set of the interconnected electrical subsystems into a further subsystem for which a further internal state is expressed within the same common system of coordinates used before, the further internal state being communicated with other agents according to the protocol.

Abstract: The invention relates to a vehicle which includes at least four wheels and a base. Said wheels are attached in pairs at the base via connections and form a bogie consisting of a pair of wheels. Said bogies are rotatably hinged onto the base such that the pivot point of the path of the wheels is not physically present and said pivot point is located under the rotational axis of the wheels when the bogie is horizontal. The rotation of a bogie is transmitted by a transmission means to the other bogie such that the slant of each bogie in relation to the base forms an angle of identical but opposite value.
