Abstract:
A scanning optical interferometer (40) having a beamsplitter (42); a first input path (56) for an observation beam (52) and a second input path (78) for a reference beam (76) wherein both paths (56; 78) are directed towards the same beamsplitter (42) characterised in that the interferometer is configured with the first input path (56) and the second input path (78) intersecting at a location (L) before the beamsplitter (42) and in that the interferometer further comprises a dichroic filter (80) located at the intersection (L) of the two paths (56; 78) and acting to collocate both paths (56;78) in a direction towards the beamsplitter (42).
Abstract:
A method of formulating a feedstuff is provided which comprises the steps of: analysing the effect on one or both chemical and biological properties of the feedstuff of varying feedstuff ingredients and analysing the effect on the ingredient cost of the feedstuff of varying the feedstuff ingredients. The method further comprises a step of analysing the effect on a predicted production cost of the feedstuff of varying the feedstuff ingredients and a step of determining a desired formulation of a feedstuff for production on the basis of at least the analysed effects on the properties, on the ingredient cost and on the predicted production cost of varying the feedstuff ingredients.

Abstract:
Communication between RFID tags and RFID reader conveyed by an inductive link comprising a first ( 114 , 212 , 324 )and a second coil ( 118 , 216 , 328 ) interconnected by a pair of conductors ( 116 , 326 ) characterised in that the first coil ( 114 , 212 , 324 ) is configured to interact electromagnetically with a communication unit ( 110 , 210 , 320 ) and the second coil ( 118 , 216 , 328 ) is configured to interact electromagnetically with a wireless memory unit ( 122 , 316 ). The inductive link may be realised as conducting wires or as cut-outs of metal plate, and possibly employed for specifically accessing individual RFID tags by using a switching means, and employed in a system for identification and organisation of laboratory samples.
Abstract:
A spectrophotometer (2)comprising a source of radiation (6), preferably optical radiation, disposed to emit radiation at a plurality of wavelengths towards a sample in a sample holder (4) and a detection arrangement 8 for detecting the radiation after its interaction with the sample. The sample holder (4) is adapted to present a plurality of different path lengths for the emitted radiation through the sample. An arithmetic unit (10;10b)is operably connected to receive an intensity dependent output from the detection arrangement (8) and is adapted to store an intensity value of the detected emitted radiation indexed to its wavelength at two or more path lengths of the plurality of different path lengths and to calculate a value dependent on the ratio of the indexed intensity values at each of two path lengths by which an indication of the presence of a substance of interest withiA spectrophotometer (2)comprise a source of radiation (6), preferably optical radiation, disposed to emit radiation at a plurality of wavelengths towards a sample in a sample holder (4) and a detection arrangement 8 for detecting the radiation after its interaction with the sample.

Abstract:
A compact interferometer and a moving means and a light emitter for an interferometer. The compact interferometer has increased light throughput and may be provided in a single block of e.g. metal in order to be easier to manufacture, set up, align and in which the atmosphere is more easily controlled. The moving means has a rigid magnet part travelling within a coil part, increasing the stiffness and controllability of the system. The light emitter is a filament having a bifilar coil where no part of the filament extends within the coil.
