  • Publication number: 20130217984
    Abstract: A method for determining an autofluorescence value of skin tissue of a subject, comprising the steps of: irradiating material of said skin tissue with electromagnetic excitation radiation of at least one wavelength and/or in at least one range of wavelengths; measuring an amount of electromagnetic, fluorescent radiation emitted by said material in response to said irradiation; and generating, based upon said measured amount of fluorescent radiation, a measured autofluorescence value for the concerning subject.

  • Patent number: 6100750
    Abstract: A frequency-independent voltage divider includes a series arrangement of resistors connected between an input terminal and a reference terminal for receiving an input signal. An output terminal for supplying an output signal is coupled to a tap of the series arrangement. The influence of parasitic capacitances is eliminated by compensation capacitors.

  • Patent number: 6064434
    Abstract: In a beam current measurement device, including an output transistor (T1) for supplying a cathode current (Ic), a measurement output (OUTM) for supplying a measured current (Im) representing the cathode current (Ic), a first current source (Ibias1) coupled to a first main terminal of the output transistor (T1) for supplying a first current (Ibias1), and a second current source (Ibias2) coupled to a second main terminal of the output transistor (T1) for supplying a second current (Ibias2) substantially equal to the first current (Ibias1), a first cascode transistor (Ta) is coupled between the first main terminal of the output transistor (T1) and the measurement output (OUTM).

  • Patent number: 4680640
    Abstract: Errors occurring in the beam current measurement in a video output stage can be reduced by increasing the recharging rate of the capacitive load of a video amplifier, constituted by the picture display tube of a picture display arrangement, with the aid of a bias current or a quiescent current which is subtracted again from the current applied to an input of the beam current measuring circuit which is controlled by the video amplifier.

  • Patent number: 4679092
    Abstract: The distortion of an emitter-follower output stage of a video amplifier for driving a cathode of a picture display tube can be reduced without rendering a beam current control via this output stage impossible, by using a low-distortion buffer stage for producing a negative feedback signal at the output of the output stage. A higher follow rate for small signal variations can be obtained with the aid of a bias current or quiescent current which then is subtracted again from the current applied to an input of a beam measuring circuit which is controlled by the output stage.
