  • Publication number: 20150327336
    Abstract: A microwave oven or multifunctional oven with microwave heating function. The oven includes a cavity with an open front side and a front frame enclosing at least partially a front portion of the cavity. The cavity and the front frame include metal sheet. The front frame is connected to the cavity by fixing elements. A gap is formed between the cavity and the front frame. The gap encloses at least partially the front portion of the cavity and the front frame encloses the gap. The oven includes a door covering the open front side and the gap in a closed state of the door. The gap is at least partially filled by a gasket at least part of which includes one or more materials having low heat conductivity, so that the front frame is thermally decoupled from the cavity by the part of the gasket or the gap.

  • Patent number: 9153735
    Abstract: An optoelectronic semiconductor component includes a carrier which has an upper side and a lower side opposite to the upper side. At least one radiation-emitting semiconductor device is disposed on the upper side and has a radiation emission surface, through which at least a portion of the electromagnetic radiation, which is generated during operation of the semiconductor device, leaves the semiconductor device. A radiation-absorbing layer is arranged to absorb ambient light, which impinges upon the component, such that an outer surface of the component facing away from the carrier appears black at least in places.

  • Publication number: 20150191055
    Abstract: A method is provided for storing tire information in a tire sensor. For this purpose, a tire sensor is fastened to a tire having a passive RFID transponder. The RFID transponder is then supplied with energy via an energy field, with the result that the RFID transponder emits the stored tire information. If the tire sensor has determined that the tire sensor is fastened to the tire, the tire information is received and is permanently stored in the tire sensor. The tire information written to a tire sensor is preferably transmitted to the vehicle by the tire sensor and is then taken into account during a movement-dynamic function, for example.

  • Patent number: 8698385
    Abstract: In at least one embodiment, an optoelectronic semiconductor component includes at least two optoelectronic semiconductor chips, which are designed to emit electromagnetic radiation in mutually different wavelength ranges when in operation. The semiconductor chips are mounted on a mounting surface of a common carrier. Furthermore, the optoelectronic semiconductor component contains at least two non-rotationally symmetrical lens bodies, which are designed to shape the radiation into mutually different emission angles in two mutually orthogonal directions parallel to the mounting surface. One of the lens bodies is here associated with or arranged downstream of each of the semiconductor chips in an emission direction.
