    Abstract: A spectral imaging method for simultaneous detection of multiple fluorophores aimed at detecting and analyzing fluorescent in situ hybridizations employing numerous chromosome paints and/or loci specific probes each labeled with a different fluorophore or a combination of fluorophores for color karyotyping, and at multicolor chromosome banding, wherein each chromosome acquires a specifying banding pattern, which pattern is established using groups of chromosome fragments labeled with various fluorophore or combinations of fluorophores.

    Abstract: PROBLEM TO BE SOLVED: To realize high sensitivity laser spectroscopy by removing only a signal attributed to a periodic oscillation component in Fourier space thereby removing noise contained in a measurement signal and making the S/N better. SOLUTION: A system for measuring light absorption spectrum comprises an infrared semiconductor DFB(distributed feedback) laser light source 10, a collimate lens 12, a sample gas cell 14, an infrared detector 16, and a computer 20. In such an arrangement, a gas to be measured is introduced into a sample gas cell 14 and a computer 20 is operated. The computer 20 outputs a control signal and delivers a sweep signal to a function generator 22. A laser driver 24 varies the operating temperature or the driving current of the laser light source 10 thus varying the oscillation wavelength thereof continuously. Laser light is converted into parallel light and passes through the sample gas cell 14 from an incident window 14a. The infrared detector 16 detects the intensity thereof and the concentration of gas is determined based on the detected intensity.

    Abstract: A device for target prediction and collision warning for tracking objects in a region proximate to a vehicle includes a signal transmitter which provides first and second detection signals for at least partial reflection by an object located in a spatial region. The device further includes a signal receiver for receiving the deflected first and second detection signals corresponding to first and second parameter signals. A Fourier transform circuit is provided for receiving the first and second object parameter signals and generating first and second Fourier transform object parameter signals corresponding to relative range and velocity data of a target being tracked. The device includes a probabilistic neural network which preferably sorts the first and second Fourier transform object parameter signals corresponding to the relative range and velocity of a target being tracked. Operatively coupled to the probabilistic neural network is a target tracker circuit which receives the sorted first and second Fourier transform object parameter signals after at least three samples of relative range and velocity data have been measured. The target tracker generates an output signal indicative of a prediction of regression parameters of a second order or higher order equation that characterizes the change in relative range and velocity of the target being tracked.

    Abstract: PURPOSE: To lower a noise of an A/D converter by replacing a saturated part of an output of a high gain processing channel with an output of a low gain processing channel converted by a correlation formula. CONSTITUTION: An arithmetic control circuit 18 takes a data thereinto by changing a reference signal generation circuit 9 properly to perform A/D conversions 13 and 16 thereof. The results are stored into data memory circuits 14 and 17 to determine compatible formulas of a high gain processing channel 52 in which a gain is set to saturate a center burst part and a low gain processing channel 53 in which a gain is set not to saturate the center burst part. Then, an interference signal from a photodetecting means 51 is inputted into channels 52 and 53 through a switching circuit 10 to be stored into the circuits 14 and 17 separately. The circuit 18 checks the data stored into the circuit 14 to detect a saturated part and uses the data stored in the circuit 14 at parts other than the saturated part to convert the data stored in the circuit 17 by a compatible formula at the saturated part. Two signals obtained are synthesized to obtain a waveform without saturation at the center burst part.

    Abstract: PURPOSE: To precisely measure the spectral characteristic of a sample even when the emitted light is uneven by an environmental change on light source side by dividing the output light of an optical fiber and making the resulting lights incident to measuring and reference optical fibers. CONSTITUTION: The interference light from a Michelson interferometer 50 is converged to a part (d), and incident to an optical fiber 19. This interference light is divided into two by a coupler 20, and incident to optical fibers 7, 11 (for measurement and for reference). The spectral characteristic of the measured signal in an optical detector 10 contains the characteristics of a while light source 1 and the optical fibers 19, 7, 9 in addition to a sample 8. On the other hand, the reference signal in an optical detector 12 contains the spectral characteristics of the light source 1 and the optical fibers 19, 11. Since the optical fiber 11 is arranged in the same route as the optical fibers 7, 9, the optical fiber 11 and the optical fibers 7, 9 show the same spectral characteristic. Thus, the spectral characteristic of the measured signal is divided by the spectral characteristic of the reference signal, whereby the influence of an environmental change can be compensated.
