  • Spectral intensity measuring system for measuring repetitively pulsed light having a multichannel detector array and adjustment system including a digital phase locked loop
    Patent number: 5239174
    Abstract: The present invention is a system for optically sampling and electronically measuring the spectral intensity and integrated intensity and temporal characteristics of a repetitively or intermittently varying pulsed light source by using the electronic output of the system can be used to display the data about the characteristics of the light source, and it can also be used to insure proper synchronization between the source and a second system such as a spectroradiometer.

  • Motor control with digital feedback
    Patent number: 4992716
    Abstract: A motor feedback control system which in addition to a quantized digital position feedback value, uses a feedback signal which represents the error between the actual motor position and the quantized digital position. The error function is combined with the quantized digital position value to produce a digital position value with greater resolution. The combined value is differentiated to produce a velocity value for velocity feedback control of the motor.

  • Catalytic filler for electroless metallization of hole walls
    Patent number: 4287253
    Abstract: Improved catalytic fillers result from the use of hydrazine to render reducible metal salts absorbed on filler material surfaces catalytic to the deposition of electroless metal. Use of such catalytic fillers in forming insulated articles in which holes are made lead to improved electroless metallization of the barrels of such holes.
