Abstract: A method in which probes are examined by means a microscope. For an illuminated sample, spatially coherent light with at least one continuous wavelength range or a continuously tunable wavelength range is generated, and one or more wavelengths or wavelength ranges in the illumination light are selected in dependence on the prespecified method of examination. The probe is then illuminated with the illumination light with the selected wavelengths or wavelength ranges, the illumination light and the emission light coming from the probe are then subsequently separated, whereby the back radiated illumination light is suppressed in the detection beam before the detection and the emission light is detected. In such a method, the selection of the wavelengths or the wavelength ranges of the illumination light is tuned by means of the separation of the detection light and the illumination light and the suppression of the illumination light in such a manner that a prespecified control variable (R) is optimized.

Abstract: A telecommunications system and method are disclosed for mapping a Transcoder/Rate Adaptor (TRAU) protocol onto a User Datagram Protocol (UDP) for use in an Internet Protocol (IP) based Base Station System (BSS) architecture. All in-band control bits in the TRAU protocol are not relevant when using the UDP protocol. Therefore, when speech information is mapped onto a UDP datagram for transfer to a Channel Codec Unit(CCU) in a Base Transceiver Station (BTS), some of the information normally transferred between a CCU and the TRAU can be removed. For example, a Time Alignment command included in some of frame types is not needed, and should be removed. In addition, bits relating to a frame structure, such as TRAU synchronization bits, tail bits and spare control bits, should be removed from all frame types. Furthermore, a new control bit that contains a sequence number must be added to handle reordering of a packet data stream.
