| 20080250116 | METHOD AND APPARATUS FOR REDUCING POOL STARVATION IN A SHARED MEMORY SWITCH - Reducing pool starvation in a switch is disclosed. The switch includes a plurality of egress ports, and a reserved pool of buffers in a shared memory. The reserved pool of buffers is one of a number of reserved pools of buffers, and the reserved pool of buffers is reserved for one of the egress ports. A shared pool of buffers and a multicast pool of buffers are in the shared memory. The shared pool of buffers is shared by the egress ports. | 10-09-2008 |
| 20100049870 | DENSE MODE CODING SCHEME - A lookup table for searching for a longest prefix match for a key is disclosed. The lookup table provides a match for a key in a single search cycle. The number of matches stored in the lookup table is maximized by storing each match in only one location in the lookup table. The binary tree is divided into a plurality of levels and each level has a plurality of subtrees. A subtree descriptor stored for a subtree includes a field for each node in the subtree. The state of the field indicates whether an entry for the node is stored in the table. The bit vector allows indexing of the single match stored for the key. | 02-25-2010 |
| 20100250699 | METHOD AND APPARATUS FOR REDUCING POOL STARVATION IN A SHARED MEMORY SWITCH - A switch includes a reserved pool of buffers in a shared memory. The reserved pool of buffers is reserved for exclusive use by an egress port. The switch includes pool select logic which selects a free buffer from the reserved pool for storing data received from an ingress port to be forwarded to the egress port. The shared memory also includes a shared pool of buffers. The shared pool of buffers is shared by a plurality of egress ports. The pool select logic selects a free buffer in the shared pool upon detecting no free buffer in the reserved pool. The shared memory may also include a multicast pool of buffers. The multicast pool of buffers is shared by a plurality of egress ports. The pool select logic selects a free buffer in the multicast pool upon detecting an IP Multicast data packet received from an ingress port. | 09-30-2010 |
| 20110019546 | CONGESTION MANAGEMENT IN A NETWORK - Management of congestion level, in a computer-related context, is disclosed. Also disclosed is a system generating a plurality of computer network-related tables during system operation. A number of the tables are each separately indexed by a different index. The system includes at least one tangible computer-readable medium adapted to store, at each indexed location, a swap count providing an indication of the congestion level of the indexed location. The system also includes insert logic stored as instructions on the at least one medium for execution. When executed, the insert logic is operable to: i) insert, when a predetermined condition has been satisfied, a new entry by overwriting the current entry stored in the indexed location having the lowest swap count; and ii) update the swap counts in each of the indexed locations in a manner that maintains the total swap count at least substantially constant over time. | 01-27-2011 |
| 20110082866 | METHOD AND APPARATUS FOR LOGICALLY EXPANDING THE LENGTH OF A SEARCH KEY - A lookup table provides a longest prefix match for a search key longer than a lookup table's mapper key. The lookup table performs a multi-level search in one or more mappers for the result value based on a portion of the search key provided as the mapper key. The lookup table is searched in multiple passes with successive portions of the search key until the result value is found. | 04-07-2011 |

| 20090275867 | WALKING AND BALANCE EXERCISE DEVICE - A pelvic support unit is coupled to a base by a powered vertical force actuator mechanism. A torso support unit, which is affixed to the patient independently of the pelvic support unit, is connected to the base by one or more powered articulations which are actuable around respective axes of motion. Sensors sense the linear and angular displacement of the pelvic support unit and the torso support unit. A control unit is coupled to these sensors and, responsive to signals from them, selectively control the displacement actuator and articulation(s). | 11-05-2009 |

| 20110289180 | DATA CACHING IN A NETWORK COMMUNICATIONS PROCESSOR ARCHITECTURE - Described embodiments provide for storing data in a local cache of one of a plurality of processing modules of a network processor. A control processing module determines presence of data stored in its local cache while concurrently sending a request to read the data from a shared memory and from one or more local caches corresponding to other of the plurality of processing modules. Each of the plurality of processing modules responds whether the data is located in one or more corresponding local caches. The control processing module determines, based on the responses, presence of the data in the local caches corresponding to the other processing modules. If the data is present in one of the local caches corresponding to one of the other processing modules, the control processing module reads the data from the local cache containing the data and cancels the read request to the shared memory. | 11-24-2011 |
| 20110289279 | DATA CACHING IN A NETWORK COMMUNICATIONS PROCESSOR ARCHITECTURE - Described embodiments provide a method of coherently storing data in a network processor having a plurality of processing modules and a shared memory. A control processor sends an atomic update request to a configuration controller. The atomic update request corresponds to data stored in the shared memory, the data also stored in a local pipeline cache corresponding to a client processing module. The configuration controller sends the atomic update request to the client processing modules. Each client processing module determines presence of an active access operation of a cache line in the local cache corresponding to the data of the atomic update request. If the active access operation of the cache line is absent, the client processing module writes the cache line from the local cache to shared memory, clears a valid indicator corresponding to the cache line and updates the data corresponding to the atomic update request. | 11-24-2011 |

| 20110310610 | Headlamp with Backlit Side Bezel Signature Image - A lighting system for a vehicle comprises a headlamp light source. A trim piece is mounted adjacent the light source having an inner surface illuminated by light from the light source and an outer surface visible from outside the vehicle. The trim piece comprises a light transmitting plastic body, wherein a signature image is formed on the body having a foreground region and a background region. The foreground region has a corresponding surface characteristic on the inner and outer surfaces within the foreground region different from a corresponding surface characteristic on the inner and outer surfaces within the background region so that more light from the light source is transmitted through the foreground region than through the background region. The outer surface may be fully metalized to provide a pleasing appearance under ambient light conditions. | 12-22-2011 |

| 20120025105 | POWER CONCENTRATOR FOR TRANSMUTING ISOTOPES - A method of effecting a chemical, physical or transmutational change in a target material using a high power particle beam concentrated on the target material. The particle beam is scanned in a controlled manner to reduce its power density and to avoid damage to equipment which is unable to tolerate high power densities. Movement between the target and the scanned beam is synchronized to cause the scanned beam to persistently or continuously strike the target to effect the chemical, physical or transmutational change, thereby concentrating the beam on the target. | 02-02-2012 |
