Abstract: A self-locating mounting apparatus for holding objects such as sensors at specific positions on a subject's head includes a central mount constituted by a plurality of inextensible elements adapted to fit over the top of a subject's head. In addition, the mounting apparatus includes an adjustable circumferential band adapted to circle the subject's head and connect the central mount to inextensible side elements via sliding joints. A plurality of biasing elements provide a force for biasing sensor mounting units on the mounting apparatus against a subject's head, allowing for long-term sensing while minimizing interference forces on the mounting units. Advantageously, the mounting apparatus holds sensors within approximately 5 mm of their desired measurement positions over a range of subject head sizes.

Abstract: The present invention relates generally to a method of separating one or more components from a protein mixture. More particularly, this invention is directed to a method of separating one or more components of blood plasma comprising one or more filtration steps using a cellulose-based filter aid. The present invention is useful in the preparation of therapeutics, in particular plasma-based therapeutics for use in humans.
