Abstract: The disclosed embodiments are directed to a modular autonomous vehicle system comprising a blended wing body module, at least two high speed long range wing panel modules configured to interchangeably mount to the blended wing body module, at least two low speed high endurance wing panel modules configured to interchangeably mount to the blended wing body module, a vertical tails module configured to interchangeably mount to the blended wing body module, a vertical takeoff and landing fin module configured to interchangeably mount to the blended wing body module, a power train, and a wheels module with a plurality of wheels operably connected to the power train.

Abstract: Accordingly, the present invention provides a toolkit for building programmable rules of operation for a prepaid mobile communications unit and for loading the rules into the prepaid mobile unit's internal memory. A rules development language is provided with a predetermined syntax. A rule set is composed of sentences comprising strings of sequential operands terminated by a delimiter operand. Each operand comprises a low-level operator and its corresponding argument. The function of each low-level operator is predefined, with the number of corresponding arguments varying according to the operator type. Once constructed, the rules are compressed and loaded into the internal memory of a prepaid mobile unit and used to determine call restrictions, click rates, surcharges, or otherwise process calls.

Abstract: A method and apparatus for conditioning the access of a user of a remotely-accessible device, which tracks and monitors objects, by using a preprogrammed expiration time and date and comparing that to a reliable time and date source, such as a time and date received from a global positioning system receiver, and disabling the processing of signals of the remotely-accessible device if the time and date comparison reveals that the license, service, lease, rental or commodity agreement has expired.

Abstract: A computer implemented service transmits authorization codes for cellular service by way of a network connection with a user system. The user can purchase additional activation time for an already active pre-paid service. The user can also convert a previously purchased coded card to an authorization code by interacting with the service.
