Abstract: A rotor-blade assembly has a lock system to enable and disable a folding degree of freedom and a pitching degree of freedom of a rotor blade. A grip couples a blade to a hub, the blade being pivotable about a fold axis relative to the grip, the blade and grip being pivotable together about a pitch axis relative to the hub. A fold lock prevents folding of the blade in a fold-lock position and allows folding of the rotor blade in a pitch-lock position, and a pitch lock allows pitch movement of the rotor blade in a fold-lock position and prevents pitch movement of the rotor blade in the pitch-lock position. A rotary actuator carried by the grip has actuator arms coupled through linkage to the pitch lock and fold lock, and the actuator is configured for moving the pitch lock and fold lock between the fold-lock and pitch-lock positions.

Abstract: An aircraft that has a blade position control system (BPCS). The BPCS includes an actuator, a multilobe component configured for at least one of longitudinal movement along a mast axis as a function of actuation of the actuator and rotational movement relative to the mast axis as a function of actuation of the actuator. Movement of the multilobe component selectively restricts at least one of pitch movement and folding of a plurality of rotor blades.

Abstract: A self-retaining wear-pad leveler has a first plate having arms on opposing sides and forming an aperture through the first plate. A rear section is coupled to a rear portion of the first plate and has tabs extending from opposing sides of the rear section. The arms are configured for being retained about a ball of a spherical bearing assembly, and the tabs are configured to cause rotation of the leveler about the bearing when engaged by a component coupled to and rotating about the bearing.

Abstract: An adjustable length crank arm includes a first component having a longitudinal length, a second component coupled to the first component, the second component having a longitudinal length. A total length of the crank arm can be adjusted by changing an amount of longitudinal overlap that exists between the first component and the second component. The adjustable length crank arm can include a first wedge and a second wedge and at least a portion of each of the first wedge and the second wedge is longitudinally captured between the first component and the second component.

Abstract: A medical device assembly including a movable suspension arm assembly comprising a plurality of joints; a service head located at an end of the suspension arm assembly, the service head comprising a plurality of outlets; and a brake system for selectively braking the plurality of joints, the brake system comprising a plurality of user engagements, wherein the brake system is configured to detect user engagement of the plurality of user engagements and to release at least one brake of the brake system in response to detecting simultaneous user engagement of at least two of the plurality of user engagements so that a user can move the service head.

Abstract: A suspension arm assembly includes at least three horizontally aligned members relatively rotatable about each other, each adjacent pair of the at least three horizontally aligned members being connected to each other by a joint; a conduit pathway for positioning at least one conduit such that the at least one conduit extends along the at least three horizontally aligned members, outward of a load bearing periphery of the at least three horizontally aligned members; a brake system comprising a brake at each joint for selectively preventing movement of respective adjacent ones of the at least three horizontally aligned members about the joint; and at least one shell arranged about the at least three horizontally aligned members and the conduit pathway.

Abstract: A gripping assembly for gripping at least one conduit routed within a vertically adjustable medical boom head assembly includes a support, and a plurality of grip paddles pivotally mounted to the support and arranged around a central pathway for routing the at least one conduit, wherein the grip paddles are configured to pivot inwardly relative to the central pathway to grip the at least one conduit running through the central pathway.

Abstract: A suspension arm assembly including at least three horizontally aligned members relatively rotatable about each other. Each adjacent pair of members are connected to each other by a joint. At least one conduit extends along the at least three horizontally aligned members, with the at least one conduit being routed horizontally along the horizontally aligned members and not being located within a periphery of the at least three horizontally aligned members.
