An electrophoretic dispersion with at least two particle species is proposed in which a minimal number of free compounds is present in solution. To compensate for the temperature expansion, at least one damping element made of a solid is present and exhibits an almost static behavior at a high deformation rate and is elastically or plastically deformable at a low deformation rate. In this case, when a pair of the stripe electrode and the sub-strip electrode is defined as one cycle, the cycle is set to range from 10 \u03bcm through 150 \u03bcm. The collar and the arcuate finger strip are made of a resilient, flexible material such as butyl rubber. A motor is linked to the housing and causes bi-directional rotation of the plunger in relation to the housing. A server on the wireless network stores application threshold event data and manages communication device resident applications through device interaction, such as limiting access to server-side applications, updating the application, or recording the occurrence of the threshold event for other application uses.
