Title: Power distribution system having effectively zero electromagnetic field radiation
Inventor: MORAVA IRENA
IPC: H02G7/20
Filed: 1995-07-13
Granted: 2000-02-15
Abstract: Coaxially sheathed single core conductors are employed in this power  distribution  system.  A current  of  equal  magnitude  and opposite in direction to that flowing in each core conductor is fed back through the coaxial sheath of that conductor so as to create a neutralizing magnetic field generated by the current flowing through each core conductor to result in effectively no magnetic field emitting from the distribution lines. It also reduces line reactance to provide more even current distribution of the current amongst the parallel conductors.

Title: Wireless handset paging utilizing connection endpoint service identifiers
Inventor: COLEMAN FORREST L
IPC: H04W60/00
Filed: 1997-04-23
Granted: 2001-11-27
Abstract: PCS switching system processes the movement of a wireless set from one paging zone to another paging zone or from one base station to another base station at the lowest software layer in the PCS switching system thereby reducing the amount of processing required of the PCS switching system. Each base station is interconnected to the wireless switching network by communication links. When a wireless set registers on the wireless switching network via a base station, a physical object is established that will control the physical protocol used to communicate with the wireless set. In addition, a software object is established that will control the first layer of software protocol to communicate with the wireless set. When the wireless set moves to a new base station that interconnects to the wireless switching network, it initiates contact with the new base. This initialization causes a new physical object to be established. The software object is also updated to use the new physical object instead of the one established on registration. Thus, information for the wireless set is routed to the new base station via the new physical object; and hence, communication with the wireless set is maintained without going above thefirst software control layer.
