Abstract:
The present invention relates to a method and a system for protecting data in a computer network. A device is placed on a network edge in such a way, that all outgoing data has to pass through it. Separately, a set of data that is not allowed to leave the network is defined and stored in a secure form (typically, one way hash). The device determines the network protocol, file types, transforms and normalizes the passing data, and seeks the presence of the data from the defined set. If a threshold amount of the protected data is present, the device interrupts the connection or takes another appropriate action.
Abstract:
The invention provides a system for data access in a packet-switched network, including a sender/computer including an operating unit, a first memory, a permanent storage memory and a processor and a remote receiver/computer including an operating unit, a first memory, a permanent storage memory and a processor, the sender/computer and the receiver/computer communicating through the network; the sender/computer further including device for calculating digital digests on data; the receiver/computer further including a network cache memory and device for calculating digital digests on data in the network cache memory; and the receiver/computer and/or the sender/computer including device for comparison between digital digests. The invention also provides a method and apparatus for increased data access in a packet-switched network.
Abstract:
An airborne wind energy system with a rotational wing, comprising at least two airfoil blades of rigid, soft or mixed type, with appropriate controls, with a launch/landing perch and/or lighter than air balloon. An AWES blade, getting wider and thicker toward the external tip. A method of launching a pair of airborne wings.
Abstract:
Airborne wind energy system converting power of wind into power forms suitable for various industrial processes. That includes converting wind energy into internal energy of hot compressed gas, such as air or steam, and subsequent use of this energy for energy storage, synthetic fuel production, electricity generation, and other purposes. Pumped hydro energy storage, powered by airborne wind energy. A combined power plant, using natural gas combustion and wind power. A wind farm with a firm capacity, using wind driven energy storage together with electricity producing wind turbines or AWECS.
Abstract:
An improved wind power device for wind energy conversion or vehicle propulsion. Among many possibilities contemplated, the device may have a moving sail with tethered wings (101), moving in elliptical trajectory, utilize separate sheave (503) and cable drum (505), use a block and tackle (411), attached to the tether and utilize a cable having a flexible jacket with aerodynamically streamlined cross section (603).
Abstract:
A wind energy conversion system, comprising a wind powered airfoil (101) tethered to a vessel (103), an electrical generator (305, 702) powered by the motion of the vessel, an electrical cable (113, 710) connecting the generator to the land. Multiple aspects and embodiments are disclosed.
Abstract:
Downwind wind turbine with limited yaw, held by guy wires (105) attached to the top of turbine's tower (101), as well as a method of its deployment.
Abstract:
An airborne wind energy conversion system with lower input torque and/or better handling of the input torque. In one embodiment it has a ground generator, and a tether pulls an elongated member which is meshed with a gear of relatively small diameter. The system achieves relatively high initial RPM and relatively low initial torque. In another embodiment a wide and thin belt unwinds from a spool, having annulus-planet relation with the gear (like in a planetary gearbox). The gear is rotationally coupled to the rotor of the generator. In another aspect, the ratio of the wing air speed to the wind speed is normally below ⅔, which was taught as the optimum since Loyd.
