  • Method of disinfecting contact lenses with peracetic acid
    Patent number: 4986963
    Abstract: A method for disinfecting a contact lens contacts the lens with a sterilizing composition comprising about 0.0001% to 10.0% by weight peracetic acid for a time period sufficient to disinfect the lens, and then antiseptically removes the peracetic acid using a peracetic acid removing agent to leave the lens and the remaining composition sterile, biocompatible to the human eye, and isotonic to human tears. The peracetic acid removing agent can be a peracetic acid decomposition catalyst or a peracetic acid neutralizing compound.

  • Automated channel doping measuring circuit
    Patent number: 4325025
    Abstract: An apparatus for measuring the surface potential and impurity concentration in a semi-conductor body by monitoring the current flowing in a semiconductor body when the body is biased with a ramp voltage above its flat band voltage and summing the monitored current with the ramp voltage biasing the body. The apparatus provides direct measurement of surface potential and impurity concentration in a semiconductor structure and is especially useful in metal insulator semiconductor (MIS) structures.
