Abstract: A system and method is disclosed for calculating potential power generation for a wind farm, the wind farm including a plurality of wind turbines. The system and method include measuring the power generated by the wind farm; acquiring turbine data from at least a subset of the plurality of wind turbines, the wind turbine data including local wind speed and power generated at the local wind speed; acquiring wind resource data for the wind farm, the wind resource data including wind speed; generating a power curve from the turbine data and the wind resource data, the power curve plotting the relationship between wind speed and power generated; calculating power lost due to availability, subcurve, and curtailment, the power loss calculated for at least said subset of turbines; and aggregating the power lost in order to determine an aggregate power loss for the wind farm.

Abstract: The invention includes a pull-wire igniter for a pyrotechnic distress or signalling device which includes a hollow, elongated, tubular body which has a pyrotechnic composition mixture packed into one portion of the body and a small diameter, central passageway is formed through the pyrotechnic composition. A thin elongated plastic center tube is inserted through the central passageway. The outer end of the center tube is recessed at the outer end of the composition. An igniter cup is positioned firmly within the end of the center tube. A pull-wire device extends through the center tube and is exposed at the opposite end of the body so that the user can grasp the pull-wire. The igniter cup is partially filled with an igniter mixture and the end of the pull-wire extends through the igniter cup and is coated with a scratch material. A short section of shrink tubing is positioned over the coated end of the wire to isolate the scratch material.

Abstract: A disposable weather-proof safety fuse igniter is provided which includes a hollow cylindrical housing having an internally spaced sleeve provided for mounting and positioning a pull-wire type friction igniter cup. The end of the pull-wire is attached to a vent plug positioned at one end of the housing which, in turn, is attached to a finger-grip device for extracting the vent plug and pull-wire for ignition. A threaded cap is provided to cover and seal the vent plug end of the housing. The opposite end of the housing includes a compression type sealing retainer which has an internal bore for insertion of the safety fuse. A double O-ring seal can be positioned within the housing with the retainer arranged so that rotation of the cap causes the O-ring seal to be compressed against the inserted fuse.

Abstract: A simple latch assembly suitable for a lifting seat cushion in a motor vehicle comprises a latch member (9) in the form of a wire having two lobes (14, 15) each extending approximately in radial planes from a common axis (16). One lobe (14) engages a catch (2); the other (15) can be manipulated. The ends (10, 11) of the wire are fixed at spaced points (12, 13) so that rotation of either lobe (14, 15) about the common axis displaces the other and generates a restoring force in the loop biasing the lobes towards their original positions.
