A robotic coupling joint system and method are discussed herein, which may be utilized with a daylighting system or photovoltaic system to track sunlight. The system may provide a spherical joint allowing axial motion about two or more axes of the spherical joint. The joint comprises a first plate with four or more sockets, a second plate, a connector, and one or more spheres positioned between the first and second plates. The connector secures the sphere between the first and second plates. The system may also include a stand, an end effector coupled to the stand by the spherical joint, and a mobility system that is capable of actuating the end effector. The mobility system includes two or more linking elements coupled to the end effector, and a motor coupled to the linking elements to actuate the end effector to track sunlight.

A bearing for single-axis solar tracking system includes a journal with a tube portion connected to a pair of flanges that are configured as a thrust-stop. The bearing further includes a race removably connected to the journal.

In order to supply sufficient electric power to an induction heating mechanism even with a small-diameter roller, an induction heated roll apparatus includes a roller body having a hollow cylindrical shape, a drive shaft provided at each of both ends of the roller body and rotatably supported, an induction heating mechanism that is provided inside the roller body and allows the roller body to inductively generate heat, and a support shaft that extends from both ends of the induction heating mechanism and supports the induction heating mechanism. The support shaft is rotatably supported on an inner peripheral surface at both ends of the roller body via a bearing.

A solar tracker bearing apparatus mountable to an upright support post for rotatably supporting a torque tube beam of a solar tracker assembly and including: a rotatable bearing assembly supported for rotation about an axis of rotation by a stationary saddle assembly. The rotatable bearing assembly includes a central portion and first and second spaced apart arcuate peripheral portions, the central portion defining a beam slot, the first arcuate peripheral portion including a first arcuate rim bearing and the second arcuate peripheral portion including a second arcuate rim bearing, and the first and second rim bearings being spaced apart in a direction parallel to the axis of rotation of the rotatable bearing assembly. The stationary saddle assembly includes a first arcuate bearing race slidably supporting the first arcuate rim bearing and a spaced apart second arcuate bearing race slidably supporting the second arcuate rim bearing.

A swivel mechanism for a rotating cantilever post including a cantilever boom and a post, the swivel mechanism comprising at least one first gear associated with the cantilever boom and at least one second gear rotatably mounted to the post, wherein the at least one second gear is operatively associated with the at least one first gear such that rotation of the at least one second gear causes rotation of the at least one first gear, rotating the cantilever boom relative to the post.

The invention provides a reusable linkage which has a coupling which coupling has one or more male connectors formed from two or more compressible leaves; and/or one or more female connectors wherein each female connector is shaped to receive a male connector; wherein the compressible leaves of the male connector are shaped to resiliently engage the female connector and wherein the leaves of the male connector are compressible such that a male connector can be removed from a female connector.

A system for use during surgical procedures includes a flexible arm having a plurality of ball and socket segments that are interconnected for pivoting relative to one another, a universal adapter coupled with a first end of the flexible arm, and a component adapter coupled with a second end of the flexible arm. The component adapter includes a ball component that forms a snap-fit connection with one of the ball and socket segments. The universal adapter includes a male projection having a free end, an outer surface, external threads provided on the outer surface, a locking flange, and an annular groove formed in the outer surface of the male projection that is located between the locking flange and the external threads. The system has an overhead light connector having a female opening with internal threads. The external threads of the male projection are threaded into the internal threads of the female opening for securing the universal adapter to the overhead light adapter. The overhead light connector has a locking assembly with a locked position that enables the universal adapter to be unthreaded from the overhead light connector and a locked position that prevents the universal adapter from being unthreaded from the overhead light connector.
