Abstract:
The invention relates to the technical field of home networks. A home network based on the present UPnP standard (Universal Plug and Play) allows data to be interchanged between network subscriber stations. A UPnP standard may have one or more control point devices. To allow profile information such as user profile or network profile to be interchanged, the invention proposes providing a control point device firstly with an expanded device ascertainment service which can be used to find the other control point devices in the network and also with one or more additionally implemented profile services which allow the other control point devices in the network to be notified about change to profile information on a control point device.
Abstract:
The underframe of a motor vehicle seat is equipped with weight sensors for sensing a weight load on the motor vehicle seat. The weight sensors are interposed between a first structure part, such as a seat profile of a longitudinal guide, and a second structure part, such as a console or a seat shell, and sense the weight exerted through the second structure part on the first structure part. The weight sensors are fastened to the first structure part and comprise sensor bolts projecting upward. Holes for the sensor bolts are provided in the second structure part. The sensor bolts extend through the holes and one nut, which forms a surrounding grip around the holes, is associated with each of the sensor bolts. The holes of the second structure part each comprise one hole region that surrounds the holes and is configured as a cap.
Abstract:
An illumination system including a light source, a light guide including an output surface, emissive material positioned between the light source and the output surface of the light guide, and an interference reflector positioned between the emissive material and the output surface of the light guide is disclosed. The light source emits light having a first optical characteristic. The emissive material emits light having a second optical characteristic when illuminated with light having the first optical characteristic. The interference reflector substantially transmits light having the second optical characteristic and substantially reflects light having the first optical characteristic.
Abstract:
The present application discloses filters and methods of making filters. In one aspect, a filter comprises a multilayer optical film (MOF) having a first reflection band, the MOF including distorted portions, the distorted portions having a second reflection band different from the first reflection band, a transparent outer layer disposed on a first side of the MOF, and an IR blocking material residing on the MOF and between the transparent outer layer and the MOF, wherein the IR blocking material is selectively disposed in the distorted portions. In another aspect, a method of producing a filter comprises the steps of providing a multilayer optical film (MOF) having a first reflection band, distorting portions of the MOF, the distorted portions having a second reflection band, different from the first reflection band, and transferring a layer of IR blocking material to the distorted portions of the MOF.
Abstract:
Optical devices according to the present invention include a multilayer optical film in which at least one of the layers comprises an oriented birefringent polymer. The multilayer optical film exhibits low absorptivity and can reflect light approaching at shallow angles as well as normal to the film.
Abstract:
An illumination light unit includes at least two light sources that generate light at different wavelengths. The illumination light unit also includes a reflecting cavity having one or more reflectors and a controlled transmission mirror disposed at an output of the reflecting cavity. The controlled transmission mirror includes an input coupling element, an output coupling element and a first multilayer reflector disposed between the input and output coupling elements. At least some of the light from the light sources is reflected within the reflecting cavity by the one or more reflectors and is mixed. Light passes out of the reflecting cavity through the controlled transmission mirror. The illumination light unit may be used for illumination purposes, or as part of a backlight for illuminating a display.
Abstract:
A display system has a controlled transmission mirror disposed between the light sources and the display panel. The controlled transmission mirror includes a light-diverting input coupling element facing the light sources, a light-diverting output coupling element facing the display panel and a multilayer reflector between the input and output coupling elements. The controlled transmission mirror laterally spreads the light, making the illumination of the panel more uniform. The controlled transmission mirror may include a transparent substrate between the input and output coupling elements for additional light spreading. The light sources may be positioned within the controlled transmission mirror, rather than behind it. The output coupling element can be polarization sensitive so that the output light is polarized.
Abstract:
An optical system has a controlled transmission mirror that includes a diverting layer, an output coupling element and a multilayer reflector disposed between the diverting layer and the output coupling element. The multilayer reflector is spaced apart from the diverting layer. At least a first light source has a light emitting surface positioned between the diverting layer and the multilayer reflector of the controlled transmission mirror.
Abstract:
The invention relates to a decompression valve for oil-cooled step switches and transformers. The inventive decompression valve comprises a valve lid which is actuated by springs and closes the non-operating valve, said springs being arranged between said valve lid and a spring lid. Said decompression valve is entirely placed in a body (18) which is embodied in the form of a pot and fixed directly to a flange (1) and provided with an output opening (26) in the pot-shaped lateral area.
Abstract:
A semiconductor component includes a first module component and a second module component stacked one on top of the other, and a spacer arranged between the two module components. The module components are electrically connected to one another and/or to a higher-level circuit carrier by connecting elements. At at least one point, the spacing between the spacer and a contact area of the lower of the two module components is kept very small or the spacer overlaps and partially covers the contact area.
