Title: Method and apparatus for monitoring the condition of a fetus
Inventor: MACIESZCZAK MACIEJ
IPC: A61B5/103
Filed: 2002-04-02
Abstract: A method and apparatus for monitoring the condition of a fetus to assess a degree of risk of developing a permanent neurological condition is provided. A signal indicative of a fetal heart is processed to derive a degree of risk of developing a permanent neurological condition. The data indicative of the degree of risk of developing a permanent neurological condition indicates a likelihood that the condition of the fetus belongs to a class in a group of classes, where each class in the group of classes is associated with a pre-defined fetal condition. Data indicative of the degree of risk of developing a permanent neurological condition is then released. In one example, a neural network is used to obtain data indicating the likelihood that the condition of the fetus belongs to a class in the group of classes.

Inventor: HUFFER SCOTT W
IPC: D21H19/40
Filed: 2002-06-10
Abstract: A paperboard tube is rendered resistant to liquid by coating portions or all of the tube with submicron-sized particles of inorganic material that are treated to be hydrophobic and/or oleophobic. The particles can be applied directly to the paperboard, lodging in surface pores such that the particles adhere to the paperboard. Alternatively, a light coating of a tacky binder or adhesive can first be applied to the paperboard and then the particles can be applied such that they adhere to the binder. Preferably, the particles have a large surface area per gram; in one embodiment, for instance, silica particles are employed having a surface area of about 90-130 m2/g. As a result, the particles create a surface on the paperboard that is highly repellant to liquid.

Inventor: COLLINS GREGORY R
IPC: A61L2/02
Filed: 2000-12-29
Abstract: A filtration assembly (1) is presented which removes bacteria and endotoxin from a solution that a sterile fluid is produced. The sterile fluid is suitable for direct online infusion to a patient from a device, such as a dialysis machine.

Surface 18 is sealed onto the surface 12 of structure 14 so that the channels 22, 24 together with surface 12 form respective sets of first and second cavities 26 and 28. The first cavities 26 are placed in fluid communication with a vacuum source 101 via a third channel 30. The second cavities 28 are vented to the atmosphere via a fourth channel 34, through hole 35, and conduit 36. A high impedance 102 is placed in series between the vacuum source 101 and the first cavities 26. A differential pressure transducer 103 is connected across the high impedance 102 and monitors for change in vacuum condition between the vacuum source 101 and the vacuum in the cavities 26. If a fault 40 were to develop in structure 14 opening onto surface 12 and propagate to form a fluid communication path between one of the cavities 26 and adjacent cavity 28 there will be a change in the vacuum condition of the cavity 26 which will be detected by the transducer 103.
