  • Publication number: 20060226108
    Abstract: A system for measuring fluid intake by a sucking baby. The system includes: a feeding pathway for fluid flow from the fluid source to the baby's mouth, wherein the feeding pathway has a first opening in communication with the fluid source and a second opening in communication with the baby's mouth; and an indicator pathway for indicating the amount of fluid provided to the baby's mouth through the feeding pathway, wherein the indicator pathway has a first opening in communication with the fluid source and a second opening in communication with the baby's mouth. The amount of fluid drawn into the indicator pathway is indicative of the amount of fluid drawn into the feeding pathway.

  • Publication number: 20050274663
    Abstract: Disclosed is an air-water-catalyst-UV light contacting, air heating and cooling, humidifying and dehumidifying CHAMBER, which receives water that continuously recirculates through the water filtering, heating and cooling, (and deionizing) loop, which gets fresh outdoors air through the energy-efficient heat exchanger, which generates water from the atmospheric moisture, which stores and recirculates pure water through potable water holding tank, and to which is connected a novel design energy-efficient self-regulating steam distillation apparatus. Also, a water filtration system utilizing zwitterionic polymers as ion exchange and salt-absorbing and filtration media. Also disclosed are novel ionic and zwitterionic polymers, derived from cellulose.
