  • Patent number: 5946612
    Abstract: A method and apparatus for measuring telephone traffic volume in a cellular telephone system which, in a first embodiment, includes a receiver located at a proposed micro-cell site for measuring the traffic volume. In a second embodiment, a test base station transmits a signal and a processor communicates with a base station controller serving macro-cells surrounding the proposed micro-cell site to extract signal strength measurement reports transmitted to the cellular telephone network from mobile stations receiving the signal transmitted by the test base station. In a third embodiment, the test base station is located at the proposed micro-cell site and is assigned a location area identity different from that of the macro-cells surrounding the proposed micro-cell. Mobile stations operating in and around the proposed micro-cell site are required to register in the new location area and transmit a signal strength report which includes the signal strength of the test base station.

  • Patent number: 5747724
    Abstract: The invention relates to shot pellets for hunting in wet marshlands or corresponding wet areas. The shot has an inner core of copper or copper alloy and an outer layer of silver or silver alloy. No heavy metal will leach from the shot into the environmental surroundings, and the shot has no toxic effect on birds, even should they ingest a considerable quantity of shot. The shot is produced by granulating copper or copper alloy electrochemically to obtain shot cores, whereafter at least one layer is applied thereto. The outer layer always consists of silver or a silver alloy.
