A system in which remote nodes are supplied with electrical power using existing network communication links. A communication device in a system according to the present techniques routes electrical power to a remote node via a set of unused lines of a network communication link used for communication with the remote node. The electrical power distributed to the remote node may be AC or DC power.

Power distribution to nodes in a distributed system

A capillary electrophoresis method and apparatus for reducing dispersion of sample fractions are disclosed. The capillary tube in which the electrophoresis is performed has been flared, at least at its sample entrance end, to remove sharp corners which contribute to aberrations in the electric field distribution in a radial direction and result in differential migration of molecules depending on their proximity to the sharp corners. The flared tube, in contrast to a conventional tube, provides a more uniform electric field for electrophoresis and reduces undesired dispersion of the samples.
