Now Donoghue is working to make a far more practical system.
Dugan described the process some three decades later: Dugan licensed this more practical system to Altec who produced 4- and 8-channel automixers for commercial installations such as hotels, conference rooms, courtrooms and city council chambers.
Figure 8a shows the measured displacements d1 and d2 for the angles α=−10°⋯+100°, while Fig. 8b displays the forces F1=k d1 and F2=k d2 transformed into a more practical coordinate system: One component, Fnormal, points along the inward directed target normal, and the other one, Fin-plane, is the projection of the force vector onto the target surface.
While 'triculture' models that include pericytes (Nakagawa et al., 2009) may show some useful additional properties (Al Ahmad et al., 2011; Ramsauer et al., 2002), endothelial-astrocyte models can show a BBB phenotype close enough to the in vivo situation to make more practical systems for mechanistic studies and permeability assays.
However, more practical systems have been studied in [6 8], which consider the presence of interference effects.
Wilson used a more practical analog: a system in in which the effective length of a small superconducting cavity could be changed electronically.
Like an EDS system, these still needs support when stationary, but levitate at much slower speeds, making them a more practical alternative for systems with multiple stops.
A more practical, easy-to-use system may increase EM use outside of the home, thereby increasing the correspondence between event registration and pill ingestion.
