Abstract: Methods and systems are provided for a device. In one example, the device is configured to automatically grab and slip a line. The device is further configured to allow a user to actuate a side plate and a cam independently of one another.

Abstract: Methods and systems are provided for a device. In one example, the device is configured to automatically grab and slip a line. The device is further configured to decrease degradation to the line by limiting a rotation of the device via contact with the line.

Abstract: An articulating buckle including a loop side and a hook side, the loop side configured to pivotably couple with the hook side via insertion of a cylindrical bar of the loop side into a rounded groove of the hook side. Coupling via the cylindrical bar and rounded groove enables the loop side to pivot relative to the hook side while the two sides are engaged. The articulating buckle further includes a first cam latch and a second cam latch, pivotably coupled to a base of the hook side, and configured to releasably secure the cylindrical bar within the rounded groove. The first cam latch includes a first lobe, and the second cam latch includes a second lobe, wherein the first lobe and the second lobe are configured to bias the first cam latch and second cam latch, respectively, towards a locked position, when acted against by the cylindrical bar.

Abstract: A closure system for a line-engaging device is herein disclosed. The closure system comprises a latch for securing the line-engaging device in a closed position by engaging with one or more of a plurality of keepers in the device body. The configuration of the latch and the keepers is such that transition from a closed position of the closure system to an open position of the closure system may only occur following two or more actuations of the latch, this may reduce the probability of unintentional disengagement of a line or cable from the device.

Abstract: A marine current turbine rotor comprises a hub and fixed and two or more pitchable blade sections configured to reduce bending moment loads on the pitch bearings and enable the use of non-standard, low-cost structural materials for the hub, blades, and pitch shaft. A submersible pitch drive mechanism or linkage in the hub rotates the pitch shaft to cause the pitchable blade section to move to a specified pitch position. The hub cavity is configured to be “wet” without the expense and maintenance requirement of seals to prevent water intrusion, utilizing water-lubricated pitch bearings.

Abstract: A convertible harness system which may be selectively transitioned between a utility belt, sit-harness, and full body harness, is herein disclosed. The convertible harness system may include a utility belt, a leg loop assembly, and a chest harness, wherein the leg loop assembly may be reversibly coupled to the utility belt by passing a primary attachment point of the leg loop assembly through an attachment slot/opening in the utility belt and securing the primary attachment point to the utility belt by girth-hitching the primary attachment point to the utility belt using a primary attachment loop coupled to the primary attachment point. The convertible harness system disclosed herein may enable a wearer rapidly and reversibly couple a leg loop assembly to a utility belt, without removing or unbuckling the utility belt, and without use of a carabiner or other conventional locking device.

Abstract: A power generating system wherein a turbine (34) is mounted on top of a tower (30) or tethered underwater. The turbine (34) includes a rotor having a main blade (20) connected to a rotor hub (40) and an extender blade tip (22, 22?) attached to the main blade (20). During manufacture, the optimum energy-capture is determined using site-specific conditions of one or more of air density, wind speed, extreme wind, wind shear, noise and turbulence intensity. The extender blade tip (22, 22?) is chosen from a number of extender blade tips having a length that is the closest to the determined optimum energy-capture. The chosen extender blade tip is attached to the main blade either during manufacture or on-site. Alternatively, a one piece blade is produced based on information determined from the site specific conditions. The tip of such one piece blade can be customized based on the information obtained.
