Abstract: A coupler to couple a D-ring from a harness to a fall arrest device connector provides walls to guide and contain the harness webbing whilst allowing it to move freely (reducing webbing wear) and does not necessitate the removal of the coupler, connector, or D-ring as may be required for harness size adjustment. The coupler has a circular passageway which runs through the length allowing a shaft of the connector to couple to the part whilst maintaining 180 degrees of swivel. The coupler also has a groove which runs along the length to fit onto a central bar of the harness D-ring. The design is such that, during a fall, should the device break, the webbing will remain securely coupled to the D-ring of the harness.

Abstract: A retractable tool lanyard comprises a housing, a drum rotatably connected to the housing, a biasing member interconnecting the housing and the drum, a cord operatively connected to the drum and adapted to be wound about and paid out from the drum, and an engaging mechanism. The engaging mechanism comprises a locking plate connected to the drum, at least one lock pawl connected to the locking plate, and a ratchet plate. When the drum rotates at a predetermined speed, the at least one lock pawl pivots from an unlocked position to a locked position to engage the ratchet plate thereby rotating the ratchet plate with the drum. At least one of a braking mechanism and a clicker pawl are used to create friction to assist in reducing a rate of rotation of the drum.

Abstract: A system and method for correction of aberrations in a solid immersion microscopy system using a deformable mirror. A solid immersion lens is provided having a surface configured to make optical contact with a nearly planar surface of a substrate, an object to be imaged disposed on the opposite side of the substrate. A convex surface of the solid immersion lens faces an objective lens. A deformable mirror assembly, including a plurality of individually controllable actuators, receives light transmitted from the object. A control system controls in communication with the deformable mirror assembly provides individual actuation of each of the actuators of the deformable mirror to compensate or counteract the effects of aberrations.
