  • Publication number: 20040043059
    Abstract: Anti-Wrinkle Patch with a thin flat flexible sheet die cut to a shape that fits generally in the area directly below the user's eye. The flat sheet has a non-allergic adhesive substrate on one side. The flat sheet perimeter or portion of thereof has a non-adhesive convex shaped frame. A preferred embodiment includes the adhesive substrate containing additional anti-wrinkle ingredients such as anti-oxidants or other agents that claim to reduce wrinkles.

  • Patent number: 5994876
    Abstract: An electronic circuit and a method for accurately measuring intermittent current pulses supplied by a storage battery to energize a load. In the preferred embodiment, an analog integrator accumulates current pulses in response to a voltage drop across a sense resistor that is connected in series between the storage battery and the load. The voltage drop is proportional to the flow of current from the battery through the load. The output of the integrator is filtered with a low pass filter to block high frequency noise, and the output of the filter is coupled to an analog to digital (A/D) converter that transforms the filtered analog signal into a corresponding digital signal. The output of the A/D converter is supplied to a port of a processor. The processor provides a signal to actuate a reset switch coupled across the integrator. When closed at the end of each integration time period, this switch zeroes the output of the analog integrator.
