Abstract: A cellular communication tower is adapted to support a vertical axis wind turbine (VAWT) that includes a generator mechanism. The signal and power cable for the communication antennas run through the central axis or bore of the generator. The blades of the VAWT are disposed so as to avoid interferences with communication signals. The tower preferably deploys an open truss construction to avoid the impact of periodic pressure pulse as the turning blades shift out of alignment from shading the tower. Thus, with an open truss tower the turbine blades can be a larger size and still not cause such pressure pulses.

Abstract: Redistributing magnetic flux density within electro-magnetic or permanent magnet devices, as described herein, causes the device to increase its utilization of its magnetic core material and thereby increase its power density (Watts/volume). The preferred embodiment uses magnetic core bias currents, synchronized to the device's magnetizing current, through uniform, longitudinally isolated, magnetic core sections. The preferred embodiment can be complemented with local core bias currents that generate magnetic flux that oppose the incident magnetizing flux in local magnetic core sections with high flux density concentrations such as core corners. An alternative embodiment longitudinally interlaces magnetically isolated core sections of equal magnetic path length and uniform areal cross section. Another alternative embodiment redirects the magnetic flux in spiral wound inductors and transformers to the circumferential direction used in toroids.

Centralized monitoring of screening results for individual detection and screening systems of the baggage, passenger, and secondary screening zones may be provided by a combined user interface (CUI).
