An approach for managing system capacity of a satellite communications system is disclosed. A satellite communications system provides communication services to a region. A terminal () is located within the region and is configured to transmit and receive signals over a satellite () having a payload that processes the signals. The terminal () has a predetermined profile that includes service class information and rate information. A hub () is configured to receive system capacity resource configuration data that reflect capacity requirements of a service provider and to determine partitioning of system capacity over the region based upon the system capacity resource configuration data. The hub () transmits configuration information to the payload of the satellite () according to the determined partitions. The terminal () is configured to transmit a bandwidth request message to the payload. The payload selectively allocates bandwidth in response to the request message based upon the configuration information.

A method and system are provided for allocating satellite resources in a satellite communication system. A network interface is provided for making requests for satellite resources. A request processor determines whether the requests can be fulfilled based on a plurality of system constraints. The constraints can include, for example, the number of antennas on board the satellite, the number of active demodulators available on board the satellite, the configuration of a switch matrix which connects antennas to demodulators, and interference between signals transmitted to and from neighboring geographic cells. The network interface is preferably implemented in a web browser connected to a network which includes the Internet.

A motor controller for a vehicle including an electric motor that drives the vehicle, a plurality of sensors and a vehicle power controller. The vehicle power controller receives signals from an accelerator sensor and a brake sensor, converts the signals for the accelerator sensor and the brake sensor into a torque value. The motor controller comprises three components. A first component receives the torque value from the vehicle power controller. A second component converts the torque value into a torque output; and a third component controls the motor in accordance with the torque output.
