  • Multi-chamber airbed
    Publication number: 20020189019
    Abstract: A multi-chamber airbed reduces the effect of weight movement by one or more persons sleeping or sitting on the airbed. In the multi-chambered airbed of the present invention, there are at least two chambers inside the airbed, each chamber having its own air valve and representing its own portion of the airbed. The chambers are completely sealed off from each other by a barrier or septum within the airbed. Thus, when one person shifts his or her weight on the portion of the airbed over one chamber, air does not flow to the other chamber or portion of the airbed.

  • System for determining the quantity and identity of material ingested by user
    Patent number: 5460798
    Abstract: The present invention provides a device and method for determining the quantity and identity of a substance ingested by a user. A detectable material such as barium sulfate is formed into a marker and mixed with a foreign substance such as pills, capsules, caplets, poisons or other hazardous substances. This detectable marker resides in the individual's digestive tract until passed. This material is detectable by use of X-ray equipment or a fluoroscope allowing the attending physician to "see" into the individual's digestive tract to determine the quantity of foreign substance ingested by counting the number of markers. Further, if the detectable markers have a unique geometric shape, the physician can identify the ingested substance associated with that shape of marker.
