Abstract: A medical implant, such as an implantable component (22) of a tissue-stimulating prosthesis. One example of such a prosthesis being a cochlear implant. The component (22) is adapted to be implanted at or adjacent a tissue surface within the recipient, such as a bone surface. The component (22) has a housing and at least one flange (42) extending outwardly therefrom. The flange (42) can be secured to the tissue surface via a tissue fixation device, such as a bone screw (43).

Abstract: The invention provides enzyme granules, comprising a fluorescent whitening agent.

Abstract: A method for operating, especially for starting, a fuel cell such as a solid oxide fuel cell (SOFC) is disclosed which method includes a starting operation with a first or initial start phase and an optional second or intermediate start phase which is initiated when the fuel cell has reached a predetermined medium temperature below a steady state operational temperature range, before a steady state operation is activated. During the first or initial start phase fuel is subjected to an exothermic reaction with oxygen in a burner unit and output gases from the burner unit are used to warm up and passively heat the fuel cell. Furthermore, a fuel cell arrangement comprising a fuel cell, especially a SOFC hybrid system, for conducting this method is disclosed.

Abstract: An apparatus and method for substantially continuously manufacturing fuel cells are provided. Each cell generates electrical power from reactions of reactants therein. Each cell comprises component parts assembled and/or laminated together in a stacked configuration.

Abstract: Trapping, recycling, and other techniques involving catalysts are provided by this invention. The present invention provides for the retention of catalysts and other immobilized entities within a reaction region. In one aspect, the invention promotes such retention by incorporating support material regions including relatively little (or, in some cases, substantially no) catalyst (and thus, a relatively large number of catalyst adsorption sites) which can trap catalyst as it is transported through the downstream support material. In some cases, such arrangements can be achieved by using multiple beds arranged in series. In other instances, the amount of catalyst can be varied within a single bed to achieve the desired effect. The embodiments described herein can be used in systems in which the catalyst is covalently or non-covalently associated with the support surface.

Abstract: A method of digitally equalising the sound from a loudspeaker that is placed in a certain room, said room having varying acoustic properties affecting the way a user perceive the sound, is corrected in a certain part of the room, by measuring one or more impulse responses through a microphone, said impulse responses being processed in a pre-processing algorithm, in at least two parallel frequency band correction algorithms and a post processing algorithm. As an option a pre-correction algorithm can be coupled between the pre-processing algorithm and the frequency band correction filters. The pre-correction algorithm is adapted to receive input representing measured loudspeaker characteristics under ideal condition in an anarchic room, and/or parameters from a reflections attenuation algorithm.

Abstract: The present invention relates to an optical network with a number of nodes. Information is transmitted and, respectively, received in the nodes. The information is transmitted over a number of frequencies. Receiving and, respectively, transmitting of frequencies in the nodes is variable. The information is only converted to electrical signals in those nodes where the information is retrieved. Optical signals are amplified and distributed in the network via optical splitters and amplifiers. The capacity in the network can be redistributed depending on the capacity requirement in different parts of the network.

Abstract: The invention relates to a method and an arrangement for splicing optical waveguides and, more specifically, for effecting such splicing under field conditions i.e. directly in cable pits where the waveguides requiring splicing are housed. In accordance with the invention, a solidifiable refractive-index matching means is used to effect the splicing. The index-matching means is applied between the ends of the two waveguides in a support arrangement and is then solidified to form a splice having optical, ageing and temperature characteristics substantially corresponding to those of the waveguides. The temperature at which solidification is effected can be such that the refractive index-matching means is sintered to form a glass splice. The index-matching means is preferably a silica gel which can be solidified either chemically or by the application of heat.
