Abstract: A device for avoiding excessive loads on the human foot when walking comprises a shoe insole having at least one force sensor for generating a measurement signal indicating loads and/or partial loads on the foot; an analyzing unit electrically connected to the at least one force sensor for analyzing the measurement signal of the at least one force sensor; an electric power source to provide electric power to the analyzing unit; and a feedback control signal generator which generates a feedback control signal on the basis of the analysis of the analyzing unit for monitoring loads and/or partial loads on the foot, e.g., by means of an actuator, wherein the sensitive components are disposed in a housing to protect them, in particular from water and/or pressure loads. Furthermore, a method for operating the device is provided.

Abstract: A battery cell casing comprises a first casing element (1) with a first contact surface (7) and a second casing element (2) with a second contact surface (8). In an assembled position the first and second contact surfaces (7, 8) contact each other and the first and second casing elements (1, 2) encase active materials (9, 10) of a battery cell in an interior space. At least one seal layer is arranged between the first and second contact surfaces (7, 8) to seal the interior space, wherein one of first and second contact surface (7; 8) comprises a void volume layer and the other of first and second contact surface (7; 8) comprises a formable material layer, which fills voids on a surface of the void volume layer hermetically in the assembled position and forms the seal layer.

Abstract: A power management system for supplying power to an output circuit comprising a plurality of rechargeable batteries, a conversion means for converting a supply voltage to a battery voltage to enable charging of one or more of the rechargeable batteries and switch means to enable a selected battery of the plurality of rechargeable batteries to be connected to an output circuit to enable the selected battery to be discharged through the output circuit.

Abstract: The invention is a method for producing a tool which can be used to create optically active surface structures in the sub-?m range, having a support surface onto which relief surface structures are applied over the support surface by means of material deposition. The invention is distinguished by the support surface being directly contacted with a mask in which openings with diameters in the sub-?m range are provided or can be provided, by the support surface including the mask being subjected to a coating process in which the coating material deposits through the openings of the mask onto the support surface, and the mask is removed from the support surface when a partial amount of an average end structure height of the surface structures is reached and the coating procedure is then continued without the mask using the same coating material or different coating materials.

Abstract: What is described here is a method and an element of lighting rooms by selective guidance of daylight, comprising an optically transparent main body through which the light is incident into the respective room, and including plurality of structures on which light is deflected by total reflection into the respective room. The invention is characterized by the provision that the plurality of structures consists of parallel crazes.
