Modular tracker systems that include at least first and second tables or are continuous without the use of tables, a single motor driving the first and second tables, first and second intra-table drive shafts and an inter-table drive shaft. Each table includes a support structure including first and second mounting posts, a frame supported by the support structure, at least one solar panel supported by the frame, and first and second gearboxes being concentrically aligned for each table. The first and second gearboxes are each configured to produce first and second outputs. The first output has a first rotational speed, and the second output has a second rotational speed less than the first rotational speed, and is operatively coupled to the frame. The inter-table drive shaft couples the second gearbox of the first table with the first gearbox of the second table, whereby the first and second tables are rotated synchronously.

An angularly adjustable mounting device is disclosed for use with a small electronic device such as a wireless camera. Also disclosed is a method of using the mounting device. The mounting device has an attachment device extending from a rotatable bearing. The bearing is angularly rotatable with a socket formed by an expandable bearing holder that may include spaced apart arms extending outwardly from a mounting plate. Rotation of an outer housing around the arms engages an inclined ramp thereby deflecting the arms inwardly and into frictional contact bearing to inhibit movement of the camera relative to a base. The outer housing is configured to rotate in an opposing direction to allow the electronic device to be repositioned.

A configurable ball mount system that allows the user to use different spherical structure sizes and removable stem inserts to accommodate various articles being secured by the configurable ball mount system. The configurable ball mount system comprises a spherical structure having a first aperture designed to receive a removable stem insert having different attachment members and adapters. Custom configuration allows the user to interface with multiple articles of more than one manufacturer or brand.

A gearshift assembly comprises a base and a shift lever having an overmoulded ball portion comprising a pattern of recesses having straight side walls. A socket is fixed in the base and shaped to receive the ball portion of the shift lever. The socket has a sidewall with an inner surface forming part of a sphere to provide a pivotal mounting for the ball portion for pivotal movement of the shift lever over a pivotal movement range. Vertical slots in the sidewall which have parallel vertical side edges that are open at their upper ends to allow a sidewall portion between adjacent vertical slots to elastically flex outwardly during insertion of the ball portion into the socket. The pattern of recesses of the ball portion is arranged such that all sidewalls are inclined with respect to side edges of the vertical slots over the pivotal movement range.

A method of setting a cannula lock. An orientation of a bore of a brake is set by rotating a base and a head of the brake about at least one axis. An actuator is actuated to cause relative movement between the head and the base to engage internal surfaces of the shell to fix the orientation of the bore. A device may be directed through the bore and into tissue along a trajectory established by the orientation of the bore. The actuator may be rotated about its longitudinal axis to move the head and the base away from one another. Anchors coupled to the shell may be embedded into the section of tissue. The actuator may be an extraction tool for extracting a drive ring from the base of the shell to permit unembedding of the anchors from the tissue. The head and the base may be semi-spherical.

A resistive motion support mechanism joined to a mounting surface and to a base shaft for providing resistive support to the mounting surface as the mounting surface undergoes one or both of rotational and tilt movement relative to the base, the motion support mechanism including a support bearing connected to the mounting surface and to the base shaft which permits one or both of tilting and rotational motion of the mounting surface relative to the base; a pivot ball functionally attached to a portion of the base shaft; a resilient ring within a housing circumscribing the base shaft such that the resilient member is compressed between the housing and the base shaft by the relative movement between the base shaft and the mounting surface to provide a resistive force on the base shaft to resist the one or both of rotational and tilt movement; and, various means for varying the resistive force.

An articulated arm includes an arm segment, the segment attachable to at least one other segment of the arm; a ball-and-socket joint at a distal end of the arm segment, a ball of the joint including a plurality of indentations that are distributed over at least part of the surface of the ball; a rod that is slidable within the arm segment, the rod including at least one pin at its distal end, each pin of said at least one pin being configured to be inserted into an indentation of the plurality of indentations that is aligned with that pin; and an actuator mechanism that is configured to apply a distal force to slide the rod distally to insert each pin of said at least one pin into an indentation of the plurality of indentations.
