Abstract: A system for maintaining buoyant, energy-capture devices in general relative position in water in the presence of surface waves allows heeling of the energy capture devices while preventing collision. The system includes a grid of structural members that resists compression while permitting limited relative surface displacement between the first and second energy-capture devices. The structural members may be partially compressible and provide a restoring force, and they may allow heeling. Electricity from wave energy capture devices is combined in a way that smoothes variations inherent in wave action. Electricity from wind energy capture devices is combined with energy from wave energy capture devices for transmission to shore.

Abstract: An articulated erection structure is disclosed for use in mobilizing a wind energy extraction device. The wind turbine has blades capable of being disposed in side-by-side, parallel alignment for transportation. The erection structure has a mast that can be configured in a horizontal orientation for transportation with the turbine generator lowered, and reconfigured for power-generating operations in a vertical orientation with the turbine raised. The turbine generator may be mounted with an erection structure to a variety of transportation platforms, such as on a self-propelled vehicle, towed trailer, or transportation pallet. A hybrid system may integrate photovoltaic cells in addition to a wind energy extraction device.

Abstract: A multi-step signing system and method uses multiple signing devices to affix a single signature which can be verified using a single public verification key. Each signing device posesses a share of the signature key and affixes a partial signature in response to authorization from a plurality of authorizing agents. In a serial embodiment, after a first partial signature has been affixed, a second signing device exponentiates the first partial signature. In a parallel embodiment, each signing device affixes a partial signature, and the plurality of partial signatures are multiplied together to form the final signature. Security of the system is enhanced by distributing capability to affix signatures among a plurality of signing devices and by distributing authority us affix a partial signature amond a plurality of authorizing agents.
