  • Electric current measurement
    Patent number: 8344722
    Abstract: A method for measuring electric current applied to a load includes: with a sensor element having an inaccuracy, measuring an electric current supplied to a load to produce a measurement of the electric current; with the sensor element, measuring the electric current with an added perturbation current; and using measurements of the electric current taken with and without the perturbation current to refine the measurement of the electric current.
    Type: Grant

  • Simulated vernix compositions for skin cleansing and other applications
    Publication number: 20050232890
    Abstract: A composition and a method of producing a composition which simulates hydration, cleansing and other properties of native vernix. The composition contains hydrated synthetic cells in a lipid matrix to provide rheological properties which are substantially similar to those of native vernix, and may also contain proteins. In one embodiment, the composition contains cubosomes/water with up to 30% protein and about 5% lipid to about 30% lipid. The composition may be used to cleanse newborn skin, compromised skin surfaces, as well as normal skin, to provide hydration/barrier function, and other applications.

  • Simulated vernix compositions for skin cleansing and other applications
    Publication number: 20050163812
    Abstract: A composition and a method of producing a composition which simulates hydration, cleansing and other properties of native vernix. The composition contains, in one embodiment, hydrated synthetic cells in a lipid matrix to provide properties which are substantially similar to those of native vernix, and may also contain proteins. In one embodiment, the composition contains water-in-oil emulsified particles providing water vapor transport and evaporative water loss properties simulating native vernix. In one embodiment, the composition contains cubosomes/water with up to 30% protein and about 5% lipid to about 30% lipid. The composition may be used to cleanse newborn skin, compromised skin surfaces, as well as normal skin, to provide hydration/barrier function, and other applications.
