Abstract: Within a mobile station data message, the mobile transceiver reads an observed country code of a visited wireless network to determine a country of operation of the mobile transceiver. The mobile transceiver determines if the observed country code is equal to a stored country code in a subscriber identity module of the mobile transceiver. If the observed country code differs from the stored country code, the mobile transceiver transmits an inquiry data message to a central server via the wireless network to inquire as to whether or not the mobile transceiver is authorized to operate within the observed country. In response to the inquiry, the mobile transceiver may receive mobile profile data related to wireless access or authorized features of the mobile transceiver.

Abstract: A location-determining receiver collects terrain data within a work area. The terrain data comprises elevation data and corresponding location data. A path planning module or data processor defines a planned path for a drainage channel. The planned path comprises a starting point with first coordinates and a termination point with second coordinates within the work area. The drainage channel extends from the starting point to the end point such that the starting point has a higher elevation than the termination point. A user interface establishes constraint data comprising a minimum cut parameter, a maximum cut parameter, a minimum slope parameter and a maximum slope parameter. A data processor determines a validated path for the planned path or a digging plan based on compliance with the constraint data.
