Latest Patents

One of her latest patents is titled "Dynamic mapping apparatus for mobile unit acquisition and method therefor." This invention involves a system where a subscriber unit's geographic location is provided by a gateway and translated into location coordinates of a global coordinate system. The gateway identifies an orbiting satellite communication station servicing the subscriber unit's location and sends the subscriber unit's ID and location data to the satellite. The location data is then translated to an angle and range relative to the satellite's nadir using the satellite's ground track data. An acquisition or ring-alert signal is transmitted within the antenna beam where the subscriber unit is located. If the range is outside the satellite's footprint, the subscriber unit's ID and location data are routed directly to another satellite currently servicing that location.

Another notable patent is "Cellular communications with scheduled handoffs." This invention describes a cellular communications network that includes satellites projecting cells toward the earth. When a call is being set up to a subscriber unit, data describing the subscriber unit's location are sent to a switching office of the network. The switching office generates a schedule forecasting when the movement of the cells will cause the subscriber unit to cross cell boundaries. During an ongoing call, the subscriber unit determines when scheduled boundary crossings occur and ensures that the call is handed off to the scheduled cell as needed.
