Abstract: An improved design for a golf putter is described based on the principal of eliminating the moments due to gravity acting on the club as sensed by the hands. The design uses a large counter weight attached to the shaft located above the grip area of the club. The counter weight is of sufficient mass to move the center of gravity of the entire club into the grip area of the putter. Once the center of gravity of the entire club is located in the grip near where the hands are placed, the undesirable moments generated by gravity during the swing are eliminated. The golfer only senses the forces associated with accelerating the club in the direction of motion. By eliminating the moments due to gravity an improved putter design is achieved since the golfer's feel for the acceleration of the putter is greatly improved.

Abstract: Methods and systems for upgrading a storage library of a product line having a hardware component such as a storage array operable to run at low and high operating levels in which the hardware component is set to operate at the low operating level includes associating a software key with the storage library. The software key has permission instructions for the hardware component to operate at the high operating level. The hardware component is enabled to operate at the high operating level in response to the software key being associated with the storage library in order to upgrade the storage library.

Abstract: A storage library which enables capacity expansion without additional robotics hardware includes a frame, first and second modules having respective cells, and a robot. The frame supports the first module at a first frame length position such that the first cells are positioned at the first frame length position and along the periphery of a channel extending within the frame interior through the frame length. The frame supports the second module when the second module is mounted to the frame such that the second cells are positioned at the second frame length position and along the channel periphery. The robot has a support connected to the frame and a picker movably connected to the support. The picker moves through the channel to manipulate media elements held by the first cells, and to manipulate media elements held by the second cells when the second module is mounted to the frame.

Abstract: An apparatus for latching and ejecting cartridges from a cartridge tape drive in a storage library system includes a robotically actuated hand assembly. The apparatus comprises a pin extending from the hand assembly and a rotatable lever extending from the cartridge tape drive. The rotatable lever is pivotable between a first position in which the cartridge is locked in the tape drive and a second position in which the cartridge is ejected from the tape drive. The pin is operative to engage the rotatable lever for pivoting the lever between the first and second positions when the hand assembly is robotically actuated. A visible pattern is applied to the rotatable rod and offset from the axis of rotation of the rod such that the pattern appears to move into and out of alignment with the camera target as viewed by a line-scan camera when the rod rotates between the first and second positions. Accordingly, the status of the tape drive may be easily attained.
