摘要： The invention is related to use of shielding boxes on electric PCBs where protection against electromagnetic interference is to be provided. The shielding box has properties that simplify mounting on PCBs and improve the quality of the electromagnetic protection. The shielding box has means providing that it is fixed against the PCB during soldering so that displacement is prevented and so that the box is provided stable full-edged soldering against the PCB after the soldering process. The shielding box is made of sheet metal, and the fixing means of the shielding box are provided by means of precise working by means of laser or chemical etching or electrochemical etching and/or a combination of these processes.
Typical applications for the shielding box are PCBs on which there are mounted equipment like e.g. microprocessors and/or signal processors operating at high speed, and whereby high-frequency signals arise in the form of noise which has to be attenuated efficiently.

摘要： The invention provides a process for the manufacture of ultra-thin sections in an electrically conducting material, comprising: firstly removing material in an electrochemical process to a material thickness of approximately 10 to 20 micrometers; - secondly removing further material by a laser micromachining process to a ma¬ terial thickness of 1 to 5 micrometers. By combining the two methods it is possible by the electrochemical process quickly to remove a substantial amount of material. The electrochemical process is not as precise and accurate so that it may be possible to solely rely on and use this method in order to create the ultra-thin sections or translucent sections. However, by removing material by an electrochemical process down to a thickness of approx. 10-12 micrometres, enough margin is provided, so that the electrochemical process may be controlled in a manner so that it is satisfied that there is a material thickness left at the bottom of this first cavity. By thereafter applying the laser technique, in a laser micromachining process, the remaining material down to a predetermined level, e.g. 1-5 micrometres, may be achieved relatively rapidly, so that a relatively quick process for the manufac¬ ture of these ultra-thin sections in an electrically conducting material is achieved. Also a metal structure manufactured by the novel and inventive process is disclosed.

摘要： An assembly of an apparatus and a remote control, where the apparatus has a surface part a surface part adapted to support the remote control and a movable element movable between a position at which the remote control may be supported and a position at least partly covering the surface part. Thus, the surface part is only visible or accessible when the remote control is supported or in the proximity of the apparatus.

摘要： The invention relates to a method and system for reproduction of sound signals con- tained in a low frequency effect (LFE) channel in an audio reproduction system com¬ prising at least one main loudspeaker - although typically either five main loudspeakers in a surround sound system or two main loudspeakers in a traditional stereophonic system - and at least one low frequency loudspeaker (subwoofer) for reproduction of the lowest portion of the audible frequency range. According to the method and system of the present invention, the frequency range of the LFE channel is subdivided into a first frequency region below a given cut-off frequency, which first frequency region is provided to the subwoofer, and a second frequency region above said cut-off frequency, which second frequency region is provided to at least one of the main loudspeakers.

摘要： A pervasive information retrieval system is disclosed in consumer electronics and home entertainment for retrieval of audio and visual information but also information containing text, pictures etc. in a multi user and multi domain environment comprising a plurality of physically distributed sub-domains having different rendering units, such as loudspeakers, television screens etc. The user is enabled to "grab" an ongoing information rendering experience, such as listening to a piece of music or to a broadcasted radio channel, watching a film or a broadcasted television programme, move to another sub-domain and "throw" the experience onto that sub-domain, where the experience will continue without the need to further operate the rendering units in the selected sub-domain.

摘要： A frame construction applied to be installed as a decorative frame around objects and at the same time to act as a stabilizing element of thin plate equipment surfaces like in aluminium front - or cover plates. The frame construction is configured to have three elements, of which the first member (100) being visual and normally located on the front of the equipment. The second member (110) is an object alike a rubber band that's part of the fixation of the first member into the third member (120). In addition to be the fixture and supporting structure for the first and the second member, the third member may constitute the surface of the appliance, e.g. a front grill of a speaker system in the dashboard of a car.

摘要： The invention relates to a method and a system for optimizing the performance of a loudspeaker system as perceived by user.
The physical part of the speaker system is adjustable which enables the speaker units to be placed in positions that imply maximal acoustical performance. This is obtained by combined means to: 1) bring the speaker in a specified position and 2) apply accordingly position dependant individual acoustical filters inserted in the signal path to each individual speaker.

摘要： Electronic images that are degraded by noise and data reduction, such as MPEG encoding, display artefacts in the reproduced image, such as ringing ('ripples') and blocks ('huge pixels'), and noise in the image may be apparent as grainyness. By performing image analysis, both on a frame-by-frame and pixel-by-pixel basis it is possible to identify and separate edges in the image, ringing artefacts and the boundaries between block transistions. By applying noise reduction according to the analysis, followed by sharpness enhancement, it is possible to clean up the image for further utilization.
