  • Patent number: 4255046
    Abstract: A power supply for providing energy to a flash lamp comprising a plurality of capacitors connected in parallel with their outputs connected to the flash lamp. The capacitors are sequentially discharged by circuitry which continually compares the accumulated exposure with a reference signal which represents the desired exposure level. When the desired exposure is sensed, an inhibit signal is sent to the power supply preventing additional capacitors from being discharged.

  • Patent number: 4005940
    Abstract: An apparatus in which the alignment of an optical system is displayed, thereby enabling misalignments therein to be corrected. The alignment apparatus, in conjunction with the optical system, generates a narrow sample light image. This sample light image is displayed so as to depict the optical system misalignment. Thereafter the optical system is adjusted and a corrected sample light image produced. The corrected sample light image is once again displayed to insure that the optical system is in alignment.
