Abstract: An IR current sensor circuit which is operative to detect an existing current level in a conductor and to produce output signals representative of the existing current level wherein changes of the current level in the conductor can produce changes in the output signals and effect a control function in response thereto.
Abstract: A method and apparatus for preventing and treating septicemia in patient blood. The extracorporeal system includes an anti-microbial device to kill at least 99% of bloodborne microorganisms, a hemoconcentrator/filtration unit to remove approximately 90% of target molecules from the patient blood and a filter unit to remove target molecules from patient blood from the sieved plasma filtrate. Target molecules are produced by microorganisms as well as the patient's cells and include endotoxins from gram negative bacteria, exotoxins from gram negative and gram positive bacteria, as well as RAP protein mediator from Staphylococcus aureus, and cell mediators such as tumor necrosis factor-alpha, and interleukin 1-beta, complement proteins C3a and C5a, and brandykinin.

Abstract: A waste liquid and smoke disposal system which combines the functions of a smoke extraction system and a waste (typically, liquid) collection system, typically in, but not limited to, a surgical environment. The smoke extraction system and the liquid waste collection system are connected to supply the waste materials collected thereby to a waste treatment (e.g. decontamination and/or sterilization) and disposal system. In a preferred embodiment, the waste treatment system includes a plurality of heat exchanger units for efficient controlling of the temperature of the waste material during the waste treatment process. These three systems are all combined into a integrated system wherein the treated waste can be safely returned to the ambient. In one embodiment, the system is provided as a cart-mounted apparatus to provide mobility.
