  • Method of interrelating a master computer with a peripheral device
    Patent number: 4591978
    Abstract: A master computer of a controlled system is interrelated with the executory computer of a peripheral device via a standard serial interface. This relationship centers in the programming of the executory computer to make available on command from the master computer substantially all of the functions of the peripheral device, as well as the data stored in the executory computer, and also to lock out the keyboard of the peripheral device on command to prevent operator intrusion.

  • Compensated densitometer
    Patent number: 4080075
    Abstract: The output of a test light of a densitometer is divided into a test beam and a reference beam. The test beam is caused to traverse film samples, and impinge on a detector that produces a signal responsive to the intensity of the received light. A second detector is arranged to receive the reference beam, which does not traverse the film sample. A measuring system is responsive to the output of the first detector, and utilizes the output of the second detector to compensate for variations in the intensity of the test light.
