Abstract: A docking board removably coupled to a processor board that does not function when not operatively coupled to the docking board. The docking board sends power to and receive a control signal from the processor board when operatively coupled to the processor board and does not send power and does not receive a control signal when not operatively coupled to the processor board. The docking board is removably coupled to an expansion board that performs a computer function that is not performed by the processor board and the docking board. The docking board sends power and a control signal to the expansion board when the docking board is operatively coupled to the processor board and the expansion board, and does not send power and does not send a control signal to the expansion board when the docking board is not operatively coupled to the processor board and the expansion board.

Abstract: A flywheel formed of a composite material having fibers, oriented substantially in a circumferential direction around the flywheel, embedded in a matrix material. The flywheel having an inner surface, an outer surface, and a thickness therebetween and defining an axis of rotation. A plurality of load masses are distributed circumferentially on the inner surface at a longitudinal segment along the axis. A rotation of the flywheel about the axis with a rotational velocity generating hoop stress in the fibers in the circumferential direction and through-thickness stress is generated in the matrix material in a radial direction. Each load mass produces a force on the inner surface operative to reduce the maximum through-thickness stress in the matrix material as the flywheel rotates about the axis. The rotational velocity otherwise sufficient to produce structural failure of the matrix material produces structural failure of the fibers and not the matrix material.

Abstract: This invention provides for a method to provide the highest possible stored energy density (Watt-hour/kg) in rotating composite flywheels, which in turn will enable an increased application of said devices. Segmented high density (mass loading) materials are positioned and bonded against all free inner surfaces of a high strength low density composite rotor/rim. Traditional composite flywheels do not incorporate mass loading of the composite rotor, i.e., most of the stored energy is contained in the rotating composite rotor. The segmented materials do not fail under the high centrifugal loads, thereby contributing significantly to the overall stored energy density of the composite flywheel system. The high strength composite rotor is engineered to withstand the additional centrifugal loading effects imparted from the segmented masses. An additional benefit from completely loading the inner surface of the composite rotor as uniformly as possible is that it minimizes any unwanted rotor dynamic instabilities.
