Abstract: Multiple bandwidth requestors (220), a bandwidth manager (420) and a forward link (410) from the bandwidth manager to the bandwidth requestors are used to allocate bandwidth in a return link beam (210). The uplink bandwidth allocation is preferably based on the information to be transmitted provided by the user Automatic Data Processing Equipment (ADPE) (300) and overall system data loading. The preferred method exercised by the bandwidth manager (420) allocates bandwidth on the return link (210) to individual user terminals in either a minimal rate required for the protocol being exercised (213), a committed information rate required for the services being requested, or a fair share rate (214) that allows maximum transfer of data from the user terminal (201) to the gateway (400).

Abstract: The present method for allocating bandwidth in a satellite communication system includes determining an uplink assignment of uplinks to user terminals and a gateway. The uplink assignment is preferably based on input parameters including a gateway uplink efficiency, a user terminal uplink efficiency, and a traffic ratio between the user terminal and the gateway. The method also determines a downlink assignment of downlink to the user terminals and one or more gateways. The downlink assignment is preferably based on traffic offered to the user terminals and the gateways as dictated by the uplink assignment. Either of the uplink assignment and downlink assignment may be integer or non-integer assignments.

Abstract: The present method (300) for allocating bandwidth in a satellite communication system (500) includes determining (304) an uplink assignment of uplinks (512) to user terminals (506) and a gateway (504). The uplink assignment is preferably based on input parameters including a gateway uplink efficiency, a user terminal uplink efficiency, and a traffic ratio between the user terminal and the gateway. The method (300) also determines a downlink assignment of downlinks (516) to the user terminals (506) and one or more gateways (504). The downlink assignment is preferably based on traffic offered to the user terminals (506) and the gateways (504) as dictated by the uplink assignment. Either of the uplink assignment and downlink assignment may be integer or non-integer assignments.

Abstract: A system and method for allocating uplink and downlink bandwidth in a communication system is presented. The communication system includes a communication platform, a plurality of spokes and at least one hub. The plurality of spokes and at least one hub communicate through the communication platform. Each spoke includes spoke uplink bandwidth and spoke downlink bandwidth and each hub includes hub uplink bandwidth and hub downlink bandwidth. The allocation of bandwidth among the spokes and hub may be dynamically adjusted based on the present user demands. Additionally, if the communication system is a packet switched system, empty packets may be discarded at the communication platform and the bandwidth that was previously allocated to the packets may be reallocated.

Abstract: A three-phase power system comprising a simple, low cost processor and associated software algorithms for determining true three-phase power factor without having to convert between wye and delta configurations and without having to employ trigonometric calculations or having to measure phase. The processor monitors the source power lines of the three-phase power system by sampling voltage levels and current levels from these power lines and generates data values representative of instantaneous and average three-phase power factor from these levels. The processor uses these data values of power factor and algorithms to detect momentary power loss conditions and surge conditions and takes action to protect the motor and load of the three-phase power system from damage when these conditions occur.
