摘要:
A solar electric vehicle (SEV) with large foldable surface area that can be oriented towards the sun for peak generation of electricity. The surfaces of the SEV are mounted on a flexible chassis for elevation tracking, while the drive train provides azimuth tracking. The SEV also integrates the conversion of power from various sources, to various storage or power consumption devices.

A scalable switch, a system of switches and methods, configured to sense a carrier at the output of the respective switch. The invention intelligently, and dynamically, controls the connection of a respective switch input to a respective switch output as a function of a carrier being present, or absent, at a selected output. Alternatively, a control plane is adopted to make request to send and acknowledge clearance to send. These control methods operate on a step-by-step manner allowing fast and parallel connectivity to be established to connect a variety of interfaces, including Ethernet, PCI, SCSI, and FibreChannels. The present invention reduces switch cost, energy cost, and switch volume, while allowing scalability of connection requirements, reduction of delay, and promotion of green IT.

An agile digital communications network has a number of routers that serve as nodes in a mesh network communicating between a user device (e.g., computer, server, etc.) and a target device (e.g., disc storage cabinets, tape, jukebox, etc.). The routers operate on an open shortest path first protocol, each router having two or more interfaces or links to other routers. When a link connected to a router is down and is in the shortest path to another router identified in a communication packet, the packet is forwarded to the identified router on a precalculated alternate route that does not use the unavailable link. IP tunneling assures that routing loops do not occur and send the packet back to the router with the unavailable link because it would have been in the shortest path of an intermediate router. A tunneling technique is provided that maximizes the levels of encapsulation needed at two, regardless of the size or configuration of the network. An unavailable link is not broadcast immediately throughout the network, giving the link an opportunity to be restored before all of the routers are called on to recalculate the shortest paths and alternate paths. During a short interval following the discovery of an unavailable link, then, a router connected to that link is in a state identified as the Use Alternate Path state, and the link is repeatedly checked for availability. Each router calculates and stores the alternative paths to each other router after first calculating the shortest path to each other router. The alternate paths are pulled up and used when an unavailable link is detected. Dijkstra's algorithm is used to calculate the shortest paths. A new algorithm called the iterative dynamic Dijkstra's algorithm is used to calculate the alternative routes.

A lightweight, small volume and highly portable solar electricity collector. The collector may be configured as a solar umbrella made up of components that are able to fold up into a small package and fit inside of a portable canister or cover. The collector may include a single stage or multiple stage concentration to focus light from foldable yet rigid reflective surfaces onto photovoltaic cells. In a single stage system, light is concentrated by a parabolic mirror directing sunlight onto arrays of photovoltaic cells. With a two stage solar concentration, the first concentration is made with a parabolic foldable umbrella. A 3-stage solar collector is also disclosed.

An apparatus of a gas turbine for the purpose of converting the pressure and temperature energy of a gas into rotational kinetic energy of a turbine; through an axial injection of such gas into the center of flat disks to perform work as the gas moves outward in one or more spirals cut out of these flat disks; such that the gas experiences a gradual release of pressure along the length of the spirals as the gas presses down on the width and length of the spiral; with the spiral being of many turns such that the radius of the spiral is a prescribed increasing function of turns of the radius; and the spiral has a long length in the order of a meter, a moderate width in the order of a centimeter, and a shallow depth being a small fraction of a millimeter.

A new architecture for networked data storage is proposed for providing efficient information processing, and transportation. Data is processed, encrypted, error checked, redundantly encoded, and stored in fixed size blocks called quanta. Each quantum is processed by an Effective Cross Layer protocol that collapses the protocol stack for security, iWARP and iSCSI functions, transport control, and even RAID storage. This streamlining produces a highly efficient protocol with fewer memory copies and places most of the computational burden and security safeguard on the client, while the target stores quanta from many clients with minimal processing.
