Abstract: There is provided a method for providing a target position for a robotic speaker in an environment. The method includes receiving sensor information from one or more sensors related to the environment, obtaining at least one of initiation gesture information, position information, and face direction information based on the sensor information, the face direction information related to one or more users present in the environment, obtaining the target position of the robotic speaker in the environment by performing a calibration process based on the at least one of initiation gesture information, position information, or face direction information and one or more and acoustic properties of the environment, and positioning the robotic speaker at the target position.

Abstract: The invention relates to a flat textile material (2) for placing on a human or animal body in order to capture and/or transmit electrical signals, comprising: a longitudinal direction (4); a traverse direction (6) running perpendicular to the longitudinal direction (4); an extension plane (8); a thickness direction (10) orthogonal to the extension plane (8); a first layer (34) facing the body; a second layer (36) facing away from the body; and at least one electrode (20), arranged on or in the first layer (34), for placing on the body, wherein: the electrode (20) comprises electrically conductive threads (50, 52); the second layer (36) comprises electrically non-conductive threads (56, 58) having a first water absorbency; threads (64) extending in the longitudinal direction (4) and having a second water absorbency are provided either in the first layer (34) or in the thickness direction (10) between the electrode (20) and the second layer (36); and the second water absorbency of these threads (64) is greater

Abstract: Die invention relates to a drive belt, in particular V-belt, V-ribbed belt or toothed belt on an elastomer or polyurethane base, with belt backing and at least one tension member, comprising an optically detectable load and wear state display. According to the invention, a recess if formed over at least one belt section, and accommodated a flat support, wherein the support is furnished, in particular coated or impregnated with irreversibly thermochromic pigments, in such manner that a collour change or discolouration takes place at a predeterminable temperature load threshold.
