Abstract: A network node enables a wireless device to communicate with a local service device, such as a printer or a projector, of a Local Area Network (LAN) or Wireless Local Area Network (WLAN). The network node is connected both to a communication network and to the LAN or WLAN. The method includes identifying a multicast Domain Name System (mDNS) request, where the mDNS request is received from the wireless device, and assigning a LinkLocal (LL)-address for the wireless device. The method retrieves a local IP-address of an Authentication and Authorization Service (AA-S) having authorization information regarding a local service device, and authenticates, with the AA-S which type of services, that the wireless device is authorized to use. A local IP-address of the local service device is retrieved, and service data is conveyed between the wireless device and the local service device, by applying the LL-address of the local service device.

Abstract: A method and apparatus for measuring a vitamin K antagonizing anticoagulant present in a sample (116), arranged to: irradiate (304) the sample (116) with light from a light source (114) for exciting the anticoagulant through its absorption of the light, the excitation of the sample (116) resulting in a fluorescent emission from the sample (116); measure (306) the fluorescent emission from the sample (116); determine (308) a fluorescence lifetime (T1) of the fluorescent emission of the sample (116); determine (310) an intensity (A1) of the fluorescent emission at the fluorescence lifetime (T1); and determine (312) a amount (c) of the anticoagulant, as a function of the intensity (A1) of the fluorescent emission at the fluorescence lifetime (T1).

Abstract: A device, system, and methods are disclosed for detecting the presence or determining a quantitative amount of at least one drug substance from exhaled breath of a subject in-situ. A collecting surface has a Surface Enhanced Raman Spectroscopy (SERS)-active layer that comprises at least one SERS-active material.

Abstract: The invention relates to a fibre-optic Mach-Zehnder Interferometer for measuring such as change in length. Two light conducting fibres (1,2) are connected to a coherent light source (5). A measurement converter (6), actuated by a measurement quantity (P) changes the length of the optical path and thereby the phase angle for the light wave in one fibre (2). The phase angles for the light waves in the fibres (1, 2) are compared and a corresponding output signal (I) is fed back to compensate for the phase angle change in the measurement converter (6). To make the comparison result (I) independent of the light intensities in the light conducting fibres (1,2) these are connected to an opto-electronic directional coupler (7). This is selected such that the output signal (I) varies as the phase displacement .phi., according to the relationship: I=2.times.A.times.B.times.sin .phi., where A and B are the amplitudes of the light waves in the fibres (1,2).
