Abstract: A tax return preparation kit is provided that contains a disposable tax return preparation device for receiving taxpayer input of tax related data for use in preparing an electronic tax return. The disposable tax return preparation device is adapted to prepare an electronic tax return based on the tax related data. A communications cable is also provided for communicatively coupling the disposable tax return preparation device to a telecommunications system, for transmitting the electronic tax return to a remote tax return preparation system also coupled to the telecommunications system. The remote tax return preparation system is adapted to receive the tax return prepared by the disposable tax return preparation device, confirm the tax return, and electronically file the tax return with a tax authority.

Abstract: A method and a device for image producing measurement of fluorescent light, according to which a sample containing fluorophores of different species is irradiated with excitation light of at least one excitation channel defined by its spectral properties. The fluorescent light emitted by the sample is received by at least one detection channel defined by its spectral detection characteristic, and is converted into a digital signal, which is stored for further processing The properties of a number of measuring channels, respectively defined as specific combinations consisting of an excitation channel and a detection channel, are automatically set before conducting the measurement according to the result of a mathematical optimization process, which takes into account the fluorescence characteristics of at least some of the fluorophores presumed by the user to be in the sampler.

Abstract: The invention relates to a method for conducting the spectral differentiating, imaging measurement of fluorescent light, according to which a sample containing fluorophores of different species is irradiated with excitation light of at least one excitation channel that is defined by its spectral properties and/or the excitation time. The fluorescent light emitted by the sample is received by at least one detection channel, which is defined by its spectral detection characteristic and/or the detection time, and is converted into a digital signal. The digital signal is stored for further processing in a memory unit of a digital data processing system.
