Abstract: A microwave-safe inlay includes an RFID chip, an antenna, and a substrate having special shielding surfaces. These shielding surfaces are arranged in such a manner that they block microwave radiation, while communication in the HF/NFC and UHF range continues to be possible. The inlay is thin, mechanically and thermally durable, and can be used with or without shielding elements to be additionally placed under it. It is particularly intended for use with and integration into reusable microwavable dishes, so as to allow reliable identification and writing and/or reading of additional information, as well.

Abstract: The present disclosure is directed to a playing surface for a shuffleboard including an impregnated substance. The playing surface may include a base layer, a first finish layer, and a second finish layer. In some embodiments, the base layer may be made of wood and the first and second finish layers may be formed from a polymer or epoxy. The first finish layer may be produced by pouring a first layer of epoxy onto the base layer, and the second finish layer may be produced by pouring a second layer of epoxy onto the first finish layer at least 24 hours after the pouring of the first layer of epoxy. The second finish layer may be impregnated with a particulate substance after a predetermined amount of time has passed since the pouring of the second layer of epoxy.

Abstract: For improved durability during use in a microwave oven, and at the same time, good readability of a smart label, it is provided that a flat RFID inlay made up of an RFID chip and an antenna is applied to a metal shield that is made up of at least two mutually overlapping foil sections. A recess in the foil sections is enclosed by the antenna of the RFID inlay. When such a smart label with the metal shield is applied in advance to a microwave dish, and a shielding element that is impermeable to microwave radiation in the microwave oven is temporarily overlaid on the smart label from the opposite side, such a smart label can be used in the microwave oven without damage, but remains readable outside the microwave oven, and without the shielding element.

Abstract: The invention relates to a method for producing a three-dimensional shaped object without height limitation by means of layer-by-layer material application, wherein geometric data for the shaped object, a substrate part having a base surface for holding the shaped object, flowable first and second material, and a transfer body are provided. Material portions of the flowable first material are applied to the base surface and/or to a solidified material layer of the three-dimensional shaped object located on the base surface in accordance with the geometric data in order to produce a material layer of the three-dimensional shaped object. The material layer consisting of the first material is solidified.

Abstract: In certain aspects, a quasi-rigorous electromagnetic simulation, such as a domain decomposition-based simulation, is applied to an area of interest of a lithographic mask to produce an approximate prediction of the electromagnetic field from the area of interest. This is then applied as input to a machine learning model, which improves the electromagnetic field prediction from the quasi-rigorous simulation, thus yielding results which are closer to a fully-rigorous Maxwell simulation but without requiring the same computational load.

Abstract: A method for producing a portable data carrier by means of a continuous production method, in particular a roll-to-roll method, includes the step of processing at least one foil in the form of roll goods. The unrolled foil is coated with an adhesive at least partially on at least one side. Subsequently, the foil is scored along at least one fold edge on at least one side of the foil. The foil is then folded along the scored fold edge in exact register and bonded. For this purpose the foil is folded in the direction of the side that is coated with adhesive, wherein the side coated with adhesive is arranged on the opposite side of the foil which has at least one scored fold edge, along which the folding is effected. Finally, data carriers are punched out in exact register from the at least one folded and bonded foil.
