A positionable tool support device is mounted near a work surface for supporting a tool for a user. The tool support device includes a surface mount to secure the tool support device to a support surface. A gravity-balancing articulated arm assembly is coupled to and extends from the surface mount. The gravity-balancing articulated arm assembly is selectively adjustable about both vertical and horizontal axes. A rigid support extension is coupled to the gravity-balancing articulated arm assembly for selective rotation relative to the gravity-balancing articulated arm assembly. A flexible tensile member is coupled to and extends, in a relaxed state, vertically downward from the rigid support extension. The tensile member is coupled to the tool.

Devices for the support of tools

An exoskeleton includes an arm brace coupled to an arm of a wearer and a tensile member connected to the arm brace. An actuator exerts a pulling force on the tensile member. The pulling force reduces a length of the tensile member between the arm brace and the actuator and causes the arm of the wearer to bend at an elbow.

An exoskeleton includes a first link that pivots in a transverse plane about a first vertical axis and a second link that pivots in a transverse plane about a second vertical axis. The second link is coupled to the first link. An arm support assembly is coupled to the second link and pivots about a horizontal axis. The arm support assembly includes a spring that generates an assistive torque that counteracts gravity. The arm support assembly provides the assistive torque to an arm of a wearer to support the arm of the wearer. The arm support assembly further includes a cam profile and a cam follower. Contact between the spring, cam follower and cam profile determines an amount of the assistive force provided by the arm support assembly. A cuff is coupled to the arm support assembly and the arm of the wearer.

A tool arm mount couples a tool arm to an aerial work platform. The tool arm mount includes a first mounting hook that hangs on a first rail of the aerial work platform and a second mounting hook that hangs on a second rail of the aerial work platform. The first mounting hook defines a first channel in which the first rail is received, and the second mounting hook defines a second channel in which the second rail is received. The first and second mounting hooks are coupled to a spine of the tool arm mount. The tool arm mount also includes a first lock that locks the first mounting hook to the first rail.

Methods and apparatus are described for a two-axis tracking mechanism for a concentrated photovoltaic system. Two or more components forming the support structure of the two-axis tracker mechanism, which are assembled in the field and manufactured to allow one or more lasers to align the support structure of the two-axis tracker mechanism in three dimensions, vertical (X) dimension, horizontal (Y) dimension, and diagonal (Z) dimension, at a site where the concentrated photovoltaic system is to be installed. Adjustable leveling mechanisms are built into the two or more components forming the support structure.

A product change tool for selectively engaging a product change element with an IC tester interface and disengaging the product change element from the tester interface includes a mobile frame mounted to a base frame and constrained to move relative to the base frame along an axis of linear movement, and a force mechanism for urging the mobile frame to move along the axis of linear movement relative to the base frame. The force mechanism includes first and second links pivotally connected together at their proximal ends and secured at their distal ends to the mobile frame and the base frame respectively. The distal ends of the links are spaced apart along the axis of linear movement and the proximal ends of the links are between the distal ends relative to that axis. An actuator is coupled to the proximal ends of the links for urging the proximal ends of the links in directions transverse to the axis of linear movement, whereby the spacing of the distal ends of the links along the axis changes and the mobile frame moves relative to the base frame along the axis.
