| 20110256812 | CLOSED-LOOP CONTROL FOR IMPROVED POLISHING PAD PROFILES - Embodiments described herein use closed-loop control (CLC) of conditioning sweep to enable uniform groove depth removal across the pad, throughout pad life. A sensor integrated into the conditioning arm enables the pad stack thickness to be monitored in-situ and in real time. Feedback from the thickness sensor is used to modify pad conditioner dwell times across the pad surface, correcting for drifts in the pad profile that may arise as the pad and disk age. Pad profile CLC enables uniform reduction in groove depth with continued conditioning, providing longer consumables lifetimes and reduced operating costs. | 10-20-2011 |

| 20080196833 | RETAINING RING WITH SHAPED SURFACE - A retaining ring can be shaped by machining or lapping the bottom surface of the ring to form a shaped profile in the bottom surface. The bottom surface of the retaining ring can include flat, sloped and curved portions. The lapping can be performed using a machine that dedicated for use in lapping the bottom surface of retaining rings. During the lapping the ring can be permitted to rotate freely about an axis of the ring. The bottom surface of the retaining ring can have curved or flat portions. | 08-21-2008 |
| 20090318060 | CLOSED-LOOP CONTROL FOR EFFECTIVE PAD CONDITIONING - A method and apparatus for conditioning a polishing pad is provided. The conditioning element is held by a conditioning arm rotatably mounted to a base at a pivot point. An actuator pivots the arm about the pivot point. The conditioning element is urged against the surface of the polishing pad, and translated with respect to the polishing pad to remove material from the polishing pad and roughen its surface. The interaction of the abrasive conditioning surface with the polishing pad surface generates a frictional force. The frictional force may be monitored by monitoring the torque applied to the pivot point, and material removal controlled thereby. The conditioning time, down force, translation rate, or rotation of the conditioning pad may be adjusted based on the measured torque. | 12-24-2009 |

The bottom surface of the retaining ring can include flat, sloped and curved portions. The lapping can be performed using a machine that dedicated for use in lapping the bottom surface of retaining rings. During the lapping the ring can be permitted to rotate freely about an axis of the ring. The bottom surface of the retaining ring can have curved or flat portions. | 08-11-2011 |

| 20090191454 | Pivotally actuated battery clamp terminal - A battery clamp includes a fixed collar cooperating with an adjustable collar to engage a battery terminal. In one embodiment, the adjustable collar is attached to a pivotal grip plate, the pivotal grip plate being pivotably engageable with a base attached to the fixed collar. A method of securing a battery clamp about a terminal includes positioning a clamp around a terminal of a battery, wherein the clamp includes a fixed collar and an adjustable collar. The method further includes engaging the fixed collar and the adjustable collar to the terminal of the battery by adjusting the force applied by the adjustable collar. | 07-30-2009 |

| 20090253312 | Lever lock battery clamp terminal - A battery clamp includes a collar cooperating with opposing compression plates to engage a battery terminal. The clamp further includes a locking mechanism adapted to apply a compression force between the collar and the battery terminal. A method of securing a battery clamp to a terminal includes positioning a clamp around a terminal of a battery, wherein the clamp includes a collar and opposing compression plates. The method further includes engaging the collar to the terminal of the battery by applying a force to the compression plates. | 10-08-2009 |
