Abstract: A processor controlled measuring device, especially a colour meter or aspectrophotometer, includes a measuring unit, which detects the parameters to bemeasured and converts them into corresponding electrical signals, a control arrangement cooperating with the measuring unit, which controls the measuring unit and processes the electrical signals produced thereby, and an input/output unit (5) cooperating with the control arrangement for the manual operation of the measuring device and for the display of measurement results and user instructions. The control arrangement is provided by a processor (3) on which a control program runs whichimplements the functionalities of the measuring device. Furthermore, interface means are provided which cooperate with the processor and through which the processor can communicate with an external processor, whereby measured data produced by the measuring device can be called up therefrom and control data controlling the processor can be fed to the processor. A data file system is implemented in the processor wherein the measurement and/or control data are stored in the form of data files of defined format. Furthermore, means (34, 35) are present for making the data file system (32, 4) available to a network through the interface means (6). The communication between the processor (3) and an externalprocessor connected to the network takes place by way of the data files stored in the data file system (32, 4) and can thereby be achieved without a manufacturer specific data exchange protocol.

Title: Method for improving the wanted signal in a radio receiving unit
Inventor: ROTH SABINE
IPC: H04B1/06
Filed: 1999-06-30
Abstract: Method for improving the wanted signal in a radio receiving unit It is known for a signal-strength detection unit to be used to detect the ratio of the input signal to the wanted signal obtained after it. A disadvantage in this case is that interference elements, which are also amplified, not only corrupt the output signal of the signal-strength detecticn unit, but can also adversely affect the quality of the wanted signal.      The invention is based on the object of providing a method for improving the wanted signal in the receiving unit of a communications system.      The method according to the invention for improving the wanted signal in a radio receiving unit having a channel filter, having a switch, having a control unit, having a signal-strength detection unit and having controllable amplifiers is distinguished in that the control unit drives the switch in such a manner that the switch alternately supplies a first signal upstream of the channel filter and a second signal downstream from the channel filter to the signal-strength detection unit, and that the output signal of the signal-strength detection unit is supplied to the control unit, and that the amplifiers are driven as a function of the output signal.

Title: Method and apparatus for treatment of seed
Inventor: KOPLIK VALERIE
IPC: A01C1/00
Filed: 1999-09-27
Abstract: The Invention relates to Agriculture in general, and, to the means and devices for pre-sowing seed treatment.      In the mentioned above Invention, not less than 5 % of seed is exposed to rotating polarized incoherent light in the bandwidth of 630.0 to 680.0 nm, and monochromatic polarized coherent light in the wavelength range from 630.0 to 640.0 with an electric vector variability and phase change of 0 to 180 °. The treated seed is then mixed with the non-treated seed.      The treated seed actively absorbs light quanta and becomes highly exited, starting to radiate light quanta in the bandwidth of 210 to 660 nm, with the energy 2 to 4 times exceeding the energy of absorbed quanta. After the mixing of the treated and non-treated seed, the biological luminescence of the treated seed creates a phenomenon of bioenergetic seed interaction, thus forming stable bioenergetic structures, bearing higher volumes of free energy.      Such treatment is characterized by high quality treatment results and lowered costs of the treatment itself.      The treatment device consists of sources of incoherent polarized light, positioned spiral-like as to the seed flow, and a unit combining a source of monochromatic polarized coherent light with a scanning mechanism with mirrors equipped with at least two semilucent reflecting layers, positioned one behind the other.
