Each key may be also defined by a unique region of numeric values or a unique region of color pixels allowing ease in changing keyboard location, size and orientation.

A controller for use with a guidewire, such as a vascular guidewire, provides a mechanism for gripping and applying a torque to the guidewire without the need to thread the guidewire axially through the controller and at a location close to a point of access of the guidewire. In one embodiment, the controller includes a side-access, multi-part assembly including a collet or other gripping element that applies a uniform radially inward force on the guidewire. In another embodiment, for use with guidewires having active electrically controllable elements, the controller integrally or removably incorporates a switch or other mechanism to initiate an energized state. The controller thereby permits ergonomic, single-handed control of an electronically steerable guidewire, including axially displacing, torquing and steering the guidewire.

An apparatus for holding a large format workpiece includes first and second sets of support units on opposite sides of the workpiece. Each support unit includes a support arm carrying individual mounting fixtures such as suction units for suction-holding the workpiece. The support arm is pivotably mounted on a support column, which in turn is movable along a floor-mounted rail. A riveting machine includes an upper tool and a lower tool that are movable parallel to the floor-mounted rail. To make space for the machine to set rivets in the area that is supported by a given support arm, that support arm is released from the workpiece and moved away to allow the machine to carry out its riveting cycle at that area, while the greatest possible number of the other support units simultaneously remain in place and continue to support the workpiece.
