The present invention relates generally to acquisition of data from RFID devices (132-136), such as sensor data. Prior art systems of active RFID devices have a problem of high average power consumption, and therefore, the energy source of the RFID devices needs to be replaced or charged frequently. The present invention provides a new solution wherein the RFID device has a power saving mode in which the receiver of the RFID device has a decreased ability to receive/detect RF signals. The RFID device may include a timer which is functional during the power saving mode, and the receiver of the RFID device will turn into active mode at a point of time based on the time value of the timer. Signal strength of an RF channel is indicated with a receiver, and transmission of data is dependent on the indication of the signal strength.

The invention concerns generally the technological field of antenna arrangements in mobile stations. The invention also concerns a mobile station equipped with such an antenna arrangement. One idea of the present invention is providing a planar antenna in which the printed wired board (PWB) of the mobile station is used. The planar antenna has preferably an air gap between the radiator element (216) and the ground plate (218). In order to reduce the effects of the RF fields to other phone electronics there is a sheet of low reluctance material (245) for reducing the RF fields. The sheet of low reluctance material is so located that it covers an area of the printed wired board which is not covered by the radiator element or the ground plane of the planar antenna. The low reluctance material is preferably ferrite material, such as flexible ferrite sheet, and it may be attached to the display unit (208a, 208b) or on the PWB (234).

Electrically tunable Fabry-Perot interferometers produced with micro-optical electromechanical (MOEMS) technology. Micromechanical interferometers of the prior art require high control voltage, their production includes complicated production phases, and the forms of the movable mirrors are restricted to circular geometries. In the inventive solution, there is a gap in the movable mirror, whereby mirror layers opposite to the gap are connected with anchoring. The anchoring is such that the stiffness of the mirror is higher at the optical area than at the surrounding area. This way it is possible keep the optical area of the mirror flat even if the control electrodes extend to the optical area. Due to large electrodes, lower control voltages are required.

A sealing element for sealing a component gap with respect to a flow, in particular for use in a fluid-flow machine, specifically in a turbomachine is provided. In addition a fluid-flow machine is provided including such a sealing element for sealing a component gap. The sealing element includes a hollow profile enclosing a cavity. Arranged in the hollow profile are a first opening and a second opening, which are spaced apart from each other in the longitudinal direction of the hollow profile. The first opening is formed as an inlet opening for a cooling fluid into the cavity of the hollow profile, the second opening is formed as an outlet opening for the cooling fluid from the cavity of the hollow profile. With the sealing element arranged in a fluid-flow machine, the sealing element can consequently be internally cooled by means of the cooling fluid. Furthermore, the sealing element uses the pressure gradient occurring in the flow in the direction of flow to form a stable cooling fluid flow.

The object of the present invention is to provide a method for the detection and/or quantification of the 14-3-3 proteins or their isoforms for early stage diagnosis of TSE-diseases, which method allows to perform the diagnosis in the living organism. It is furthermore an object, to detect a contamination of the sample by the parallel determination of a second antigen. This object according to the invention is solved by making use of the biochemical characteristics of the members of the 14-3-3 protein family, which bind to specific amino acid motifs like X(n)-XSXXSXXSX-X(n) or to the motif RSXpSXP (SEQ ID NO: 12) within peptides or proteins. For determining one or more isoforms or the entirety of the 14-3-3 protein(s) and for specific binding, one uses modified solid phases like e.g. microtiter plates, which are coated with a synthetic or natural peptide containing a binding motif for 14-3-3 proteins, e.g. a chemically synthesised peptide having the motif CAALPKINRSApSEPSLHR (SEQ ID NO: 1). After the addition of the extracts or bodily fluids to be investigated the detection and quantification of the generated peptide-14-3-3 protein complexes is accomplished by means of labeled antibodies. The use of the 14-3-3 protein family and/or of individual isoforms of the 14-3-3 proteins according to the invention can be employed as an effect monitor or biomonitor in aquatic invertebrates after environmental effects like the presence of polychlorinated biphenyls (PCBs), (xeno)estrogens etc. Moreover, the method can be used for early diagnosis of TSE-diseases like e.g. Creutzfeldt-Jakob disease (CJD) and its novel form (variant) in young persons (vCJD) and Bovine Spongiform Encephalopathy (BSE) or comparable diseases. Thus a diagnostic marker (surrogate marker) is available, which can be used in the living organism as a screening marker, confirmation marker or single marker.
