20140059288 | Batch Entries Sharing Individual Content-addressable Memory Entries - In one embodiment, batch entries include multiple content-addressable memory (CAM) entries, and CAM entries are allowed to be shared among different batch entries. For example, two or more batch entries might have a common set of bits (e.g., representing an address, an address prefix, etc.). Rather than consuming bits of multiple CAM entries, a single CAM entry can be programmed with this common information. Other CAM entries associated with different batch entries are programmed with the distinguishing/different values. A batch lookup operation on a batch entry of two or more CAM entries requires multiple lookup operations on the CAM entries. One embodiment uses a batch mask vector to provide information to decode what CAM entries are shared among which batch entries during a series of lookup operations, which can be performed in one or both directions through the CAM entries. | 02-27-2014 |
20140059289 | Content-addressable Memory Lookup Device Supporting Iterative Lookup Operations - In one embodiment, multiple content-addressable memory entries are associated with each other to effectively form a batch content-addressable memory entry that spans multiple physical entries of the content-addressable memory device. To match against this content-addressable memory entry, multiple lookup operations are required—i.e., one lookup operation for each combined physical entry. Further, one embodiment provides that a batch content-addressable memory entry can span one, two, three, or more physical content-addressable memory entries, and batch content-addressable memory entries of varying sizes could be programmed into a single content-addressable memory device. Thus, a lookup operation might take two lookup iterations on the physical entries of the content-addressable memory device, with a next lookup operation taking a different number of lookup iterations (e.g., one, three or more). | 02-27-2014 |
20140181503 | Rate-Controlling of Heat Generating Data Processing Operations - In one embodiment, individual or groups of heat generating data processing operations are rate-controlled such that a component, a set of components, a board or line card, and/or an entire apparatus or any portion thereof stays within a corresponding heat budget. One or more heat price tags are associated with these data processing operations which are used to determine whether or not a corresponding data processing operation can be currently performed within one or more corresponding heat budgets. If so, the data procession operation proceeds. If not, the data processing operation is delayed. Examples of such data processing operations include, but are not limited to, data retrieval from memory, data storage in memory, lookup operations in memory, lookup operations in a binary or ternary content-addressable memory, regular expression processing, cryptographic processing, or data manipulation. | 06-26-2014 |

20090149867 | CONTROLLED STEERING OF A FLEXIBLE NEEDLE - A robotic system for steering a flexible needle during insertion into soft-tissue using imaging to determine the needle position. The control system calculates a needle tip trajectory that hits the desired target while avoiding potentially dangerous obstacles en route. Using an inverse kinematics algorithm, the maneuvers required of the needle base to cause the tip to follow this trajectory are calculated, such that the robot can perform controlled needle insertion. The insertion of a flexible needle into a deformable tissue is modeled as a linear beam supported by virtual springs, where the stiffness coefficients of the springs varies along the needle. The forward and inverse kinematics of the needle are solved analytically, enabling both path planning and correction in real-time. The needle shape is detected by image processing performed on fluoroscopic images. The stiffness properties of the tissue are calculated from the measured shape of the needle. | 06-11-2009 |

20110319941 | Robot Guided Oblique Spinal Stabilization - A robotic system for performing minimally invasive spinal stabilization, using two screws inserted in oblique trajectories from an inferior vertebra pedicle into the adjacent superior vertebra body. The procedure is less traumatic than such procedures performed using open back surgery, by virtue of the robot used to guide the surgeon along a safe trajectory, avoiding damage to nerves surrounding the vertebrae. The robot arm is advantageous since no access is provided in a minimally invasive procedure for direct viewing of the operation site, and the accuracy required for oblique entry can readily be achieved only using robotic control. This robotic system also obviates the need for a large number of fluoroscope images to check drill insertion position relative to the surrounding nerves. Disc cleaning tools with flexible wire heads are also described. The drilling trajectory is determined by comparing fluoroscope images to preoperative images showing the planned path. | 12-29-2011 |
