A cellular telephone system has call management decisions made based on the exact geographic location of the mobile unit. These call management decisions include billing and taxing decisions, cell site selection, frequency selection and even cellular system selection. The decisions are continuously updated during a call whereby decisions can be made and changed regardless of where a call originated. Cell site location, and even cellular system selection, can be made in a specific manner to best serve the needs of the mobile user, the cellular system as well as the public. It is even possible for a cellular system to locate one or more of its cell sites in the geographic area served by another cellular system. In some cases, cellular systems might even share cell sites.

Cellular telephone system that uses position of a mobile unit to make call management decisions

A cellular telephone system includes a plurality of cell sites and a mobile telephone switching office. Call management, including selection of a cell site most appropriate for a call associated with a mobile unit, are made based on the geographic location of the mobile unit as opposed to the strength of the signal associated with the call. The geographic location of the mobile unit is precisely determined using a NAVSTAR global positioning system, or its equivalent. Each mobile unit includes a GPS receiver that receives information from a geostationary satellite to determine the precise location of the mobile unit. This position information is relayed to the cell site initially managing the mobile unit, and the mobile unit is handed off to a cell site that is most appropriate for the call. Initial selection of an entrance cell site is made based on signal strength, but further call management decisions are made based on location of the mobile unit.

Cellular telephone system that uses position of a mobile unit to make

A cellular telephone system (20) includes a plurality of cell sites (14) and a mobile telephone switching office (MTSO,12). Call management, including selection of a cell site most appropriate for a call associated with a mobile unit (M,M') are made based on the geographic location of the mobile unit as opposed to the strength of the signal associated with the call. The geographic location of the mobile unit is precisely determined using triangulation, a NAVSTAR global positioning system, or its equivalent. Each mobile unit includes a GPS receiver (24) that receives information from a geostationary satellite (22) to determine the precise location of the mobile unit. This position information is relayed to the cell site initially managing the mobile unit, and the mobile unit is handed off to a cell site that is most appropriate for the call. Initial selection of an entrance cell site is made based on signal strength, but further call management decisions are made based on location of the mobile unit.

A protective garment, such as a surgeon's glove, is monitored for the occurrence of a breach in that garment. The monitoring is performed using an improved version of the system disclosed in U.S. Pat. Nos. 5,036,309 and 5,109,215. The system is further improved by making the protective garment of one piece with one layer of electrically conductive material and one layer of electrically insulating material, and connecting one of the electrical contacts to the electrically conductive layer. Several forms of the protective garment are disclosed, including a dual layer garment and a triple layer garment. The triple layer garment has two forms, one of which includes an insulating layer sandwiched between two electrically conductive layers, and the other form of which has an electrically conductive layer sandwiched between two insulating layers. The apparatus also includes elements that are used to activate an alarm circuit prior to any breach in the garment reaching a condition in which a portion of the workpiece will contact the worker.

Method for monitoring a protective garment

A protective garment, such as a surgeon's glove, is monitored for the occurrence of a breach in that garment. The monitoring is performed using an improved version of the system disclosed in U.S. Pat. No. 5,036,309, issued Jul. 30, 1991. The system is improved by adding monitors for ensuring that contacts are in proper and secure electrical contact with both the worker and the workpiece. The system is further improved by adding electrical buses so that further contact monitors and garment integrity monitors can be added to the basic system and a start-up system integrity checking system. All monitors include current amplifying elements, such as transistors.
