Abstract: A control arrangement (10) for an electrical charging system for selectively connecting alternator means (18) producing charging current at each of six outputs (22,26,30,22′,26′,30′) to the output of a first battery (34) and the output of a second battery (46) serially connected to the first battery (34), comprises a plurality of switchable full wave bridge rectifiers (78) for connecting each of the alternator outputs to the second battery output (50) so that the second battery (46) is charged. The rectifiers (78) are switchably connectible to the first battery output (38) so that the first battery (34) is charged. The arrangement also includes a switching circuit (74) for switching first one, and then the next of each of the switchable circuits as the voltage across the first battery (34) is increasingly less than the voltage across the second battery (46) so that the rate of charging of the first battery (34) is determined by the amount the voltage across the first battery (34) is less than the voltage across the second battery (46).

Abstract: In a device for the automatic adjustment of the light source (2) which can be used for the illumination light of an endoscope (1) equipped with a video camera (5), a signal processing device (3) containing a circuit (14) for defining the black value of the video signal of each line of the camera image is provided. The circuit (14) supplies the output video signal to a comparator (17) which compares it with a presettable brightness threshold voltage. The control signal for adjusting the light source is determined by counting the image lines with brightness value above the threshold voltage and logically combining the count with a mathematical function. The result is that the actual value formed from the video signal is independent of the area of the bright image sections and thus of the image circle diameter of the endoscope (1).

Abstract: In laser angioplasty, it is often difficult to distinguish between healthy and diseased vascular tissue due to the low penetration power of the radiation used for illumination and other problems associated with the detection of the diseased tissue. Described herein is an instrument (10) and method for using near infrared radiation to discriminate between healthy and diseased tissue using a catheter (12) and a spectrophotometer (56). Near infrared radiation is passed at certain wavelengths to suspected tissue, and the light reflected back from that tissue is analyzed to determine the absorbance, and preferably the second derivative thereof. From identification of the absorption spectra of known diseased and known healthy tissue, it is possible to determine which tissue portions need to be treated using, for example, an ablation laser.
