Control logic is provided for controlling the detection of match sequences between the two or more segments. | 04-26-2012 |
20120105995 | Writing Data to a Tape - A method and apparatus for writing data to a tape is disclosed. A plurality of data tracks are written onto a tape simultaneously. Any data tracks written to the tape that needs to be rewritten are identified. Each re-write unit that contains a data track that needs to be re-written is accumulated. The accumulated rewrite units are written to tape when a full set of rewrite units have been accumulated. | 05-03-2012 |
20120170147 | WRITING DATA TO A TAPE - A method and apparatus for writing data to a tape is disclosed. A plurality of data segments are written onto a tape simultaneously. Any data segments written to the tape that needs to be rewritten are identified. Each data segment that needs to be re-written is accumulated. The accumulated data segments are written to tape when a full set of data segments have been accumulated. The re-written data segments each have a first field in a header that designates itself and a second field in the header that designates a second re-written data segment. | 07-05-2012 |
20120293344 | COMPRESSING AND DECOMPRESSING DATA - A technique includes compressing or decompressing data using a relative displacement of a location of a data pattern. | 11-22-2012 |

20090012648 | Robotic Arms With Coaxially Mounted Helical Spring Means - A robotic arm comprising a plurality of segments, each comprising articulated links, and means for causing each segment to bend so the arm can follow a serpentine path. A helical spring is provided coaxially with the arm to urge the links to an initial datum position, and to distribute the bending over the links of each segment. | 01-08-2009 |
20090095112 | Link Assembly With Defined Boundaries For A Snake Like Robot Arm - In a “tip following” robotic arm, the apertures through which control cables pass are arranged to ensure that the cables are maintained in contact with at least a part of the aperture, leading to a more stable and controllable arrangement. | 04-16-2009 |
20090222133 | System and Method for Controlling a Robotic Arm - A method of controlling the position of an elongate robotic arm comprising articulated segments. An actuator is associated with each segment to control its position, and a control system operates the actuators. Data representing the position of the arm is gathered and compared to input data that represents a required new position of a part of the arm. Data representing the required new position of the arm is then calculated, attempting to keep the remainder of the arm as close as possible to its previous position. The actuators are operated to move the arm into the new position. In tip following, the data representing the new position may define a path, and the arm may be fitted to the path by matching the position and orientation of a point on each pair of adjacent segments to that of the path. | 09-03-2009 |
