Abstract: Methods and apparatus related to determining and/or utilizing one or more attributes for an Internet Protocol (IP) address and/or other source identifier(s). In some implementations, the attributes may include a physical address and/or email address associated with the source identifier(s). Some implementations are directed to determining physical addresses for inclusion in a postal campaign and/or determining email addresses for inclusion in an email campaign. In some of those implementations, the physical addresses and/or email addresses are determined based on computing devices having source identifiers associated with those addresses having submitted searches with search content assigned to the campaign.

Abstract: A vertical axis wind turbine includes: a central axis that extends in a substantially vertical direction; a plurality of configurable airfoils disposed about the central axis, the plurality of configurable airfoils physically coupled to rotate together about the central axis; an angle adjustment mechanism configured to adjust an angle formed between a configurable airfoil and a radius that extends from the central axis as the configurable airfoil rotates about the central axis; and a profile adjustment mechanism that is configured to adjust a profile of the configurable airfoil as the configurable airfoil rotates about the central axis.

Abstract: An aircraft includes a fuselage having an upper surface and a lower surface and a plurality of planetary modules housed in the fuselage, an individual planetary module having a first jet engine directed outward of the upper surface of the fuselage and a second jet engine directed outward of the lower surface of the fuselage, the individual planetary module rotatable within the fuselage about a vertical axis.

Abstract: A PAVA (parallel and vertical axis) turbine includes a plurality of wing assemblies having vertical pivot shafts extending between two vertically spaced end assemblies that are joined to a central driveshaft assembly. The wing assemblies are rotatable about their respective pivot axes from a drive position in which they extend radially outwardly from the central axis and transverse to incident fluid flow to maximally capture fluid flow and rotate the turbine, to a glide position in which the wings extend tangentially to the direction of rotation and parallel to incident fluid flow to minimize drag. The wings may have articulating flaps rotating outwardly from the wing assembly in the drive quadrant to capture more of the passing fluid flow.

Abstract: A wind turbine includes a plurality of pivot shafts that are in paired parallel relationship and engaged to a central drive shaft, each pivot shaft supports a wing. Each pivot shaft rotates cyclically through 90° to move each wing from a wind-engaging orientation (drive position) in which the wing presents a flat surface approximately transverse to the incident wind, to a minimum dragposition (glide position). A gear transmission links the pivot shafts for sequential rotation in concert between the drive and glide positions.

Abstract: A wind turbine includes a quartet of pivot shafts in paired parallel relationship and transversely mounted on a central drive shaft, each pivot shaft supporting a pair of wings at opposed ends thereof, the wings offset by 90°. Each pivot shaft rotates cyclically through 90° to move each wing from a wind-engaging orientation (drive position) in which the wing presents a flat surface approximately transverse to the incident wind, to a minimum drag position (glide position). The wings of each pair of pivot shafts open into the drive position at the same time and rotational angle of the turbine. A backstop at the site of each drive position transfers force from each wing to the central drive shaft.

Each pivot shaft rotates cyclically through 90° to move each wing from a wind-engaging orientation (drive position) in which the wing presents a flat surface approximately transverse to the incident wind, to a minimum drag position (glide position). In addition, the two wings of each pair on a shaft are disposed in planes that are offset by approximately 90° about their pivot shaft, so that one is in the drive position while the other is in the glide position. The wings of each pair of pivot shafts have wings at the ends thereof that open into the drive position at the same time and rotational angle of the turbine. A backstop at the site of each drive position supports the wind load and transfers its force to the central drive shaft.
