Abstract: The “relevant” participants for each person in an online meeting may be automatically identified and a personalized view created to dynamically represent these relevant people as the meeting progresses. Relevancy of participants may be determined based on a number of factors and data from a variety of sources at the initialization of the meeting or when the participant for whom the personalized view is created joins the meeting. The relevancy computation may be updated and the personalized view dynamically changed during the meeting based on changes in participants, their participation modality, and comparable factors.

Abstract: A microfluidic separation device suitable for high throughput applications such as medical treatments, and associated methods and systems, are described. Embodiments are suitable for treatment of end stage renal disease.

Abstract: A device for separating fluids includes a microfluidic channel with one or more wall filters or membranes through which portions of the flow in the microfluidic channel can be removed. The wall filters can have precisely defined pores therein which restrict the removal of certain particles while allowing other particles and/or fluids to freely flow therethrough. Because of the high and uniform pore density and low flow resistance of these filters, the pressure drop along the microfluidic channel may result in a negative trans-filter pressure, thereby causing reverse flow of extracted fluid back through the filter and into the microfluidic channel. Precise design of the microfluidic channel and control of flow characteristics can minimize and/or eliminate this reverse flow while allowing for sufficient sweeping of the filter surface to inhibit clogging with particles.

The illuminator may be a LED emitting white light, and may provide illumination at various levels of intensity.
