Granted: 1991-03-26
Abstract: ABSTRACT           The present invention provides for a system and a method for applying a sound track to cinematic film by means of a modulated laser beam.  The method of writing sound track information on processed cinematic film having an emulsion layer on a substrate comprises the following steps.  First, a laser is directed to apply to the emulsion a light beam of sufficient frequency, intensity, area and duration in order to vaporize at least a portion of the emulsion without damaging the substrate.  Second, the light beam is passed through a mask which has a variable area for light transmission.  Finally, the light transmission area of the mask is varied by means of an audio-frequency electric signal to generate an audio-sound track on the film with this sound track being readable by cinematic film projection equipment.

Granted: 1992-01-28
Abstract: ABSTRACT OF THE DISCLOSURE       Disclosed is a system for individually monitoring the condition of a single battery or each battery and related supply cables in a multi-battery battery pack.  The system includes a means for positively indicating the condition of each battery in the battery pack.  To monitor the condition of each battery the system includes a means for comparing the voltage applied at the two terminals of each battery in the battery pack, and if this comparison reveals a deviation from a normal voltage difference, the system will indicate that the battery or related cables are faulty.  For a properly operating battery the system will provide an indication that the battery is supplying the proper voltage, and when the voltage of any one of the batteries deviates from the standard, a system provides an indication that the particular batteries so deviate and will continue to show a deviation until reset even though the defective battery shows a normal voltage under a no load condition.
