Patent application numberDescriptionPublished
20090063754COMBINED PARALLEL/SERIAL STATUS REGISTER READ - Methods and devices are disclosed, such as those involving a solid state memory device that includes a status register configured to be read with a combined parallel and serial read scheme. One such solid state memory includes a status register configured to store a plurality of bits indicative of status information of the memory. One such method of providing status information in the memory device includes providing the status information of a memory device in a parallel form. The method also includes providing the status information in a serial form after providing the status information in a parallel form in response to receiving at least one read command.03-05-2009

20100332809Methods and Devices for Saving and/or Restoring a State of a Pattern-Recognition Processor - Systems and methods are disclosed for saving and restoring the search state of a pattern-recognition processor. Embodiments include a pattern-recognition processor having a state variable array and a state variable storage array stored in on-chip memory (on-silicon memory with the processor). State variable storage control logic of the pattern-recognition processor may control the saving of state variables from the state variable array to the state variable storage array. The state variable storage control logic may also control restoring of the state variables from the state variable storage array to restore a search state.12-30-2010
20110145271METHODS AND APPARATUSES FOR REDUCING POWER CONSUMPTION IN A PATTERN RECOGNITION PROCESSOR - Apparatuses and methods are provided for reducing power consumption in a pattern-recognition processor. A power control circuit may be coupled to a block of programmed state machines to enable selective activation and deactivation of the block during a pattern search. The block may be deactivated if the pattern search is no longer active in that block and activated when needed by the pattern search. Additionally, the block may be deactivated based on an identifier of the data stream being searched. Excess blocks not used for any programmed state machines may be disabled such that they are not refreshed during a memory cycle.06-16-2011
20110145544MULTI-LEVEL HIERARCHICAL ROUTING MATRICES FOR PATTERN-RECOGNITION PROCESSORS - Multi-level hierarchical routing matrices for pattern-recognition processors are provided. One such routing matrix may include one or more programmable and/or non-programmable connections in and between levels of the matrix. The connections may couple routing lines to feature cells, groups, rows, blocks, or any other arrangement of components of the pattern-recognition processor.06-16-2011

20100289496Dipole Locator Using Multiple Measurement Points - A receiver and tracking system for identifying a location of a magnetic field source. In a preferred embodiment a plurality of tri-axial antennas are positioned at three distinct points on a receiver frame. Each antenna detects a magnetic field from a source and a processor is used to determine a location of the source relative to the frame using the antenna signals. Each tri-axial antenna comprises three windings in each of three channels defined by a support structure. The windings each define an aperture area. The windings have substantially identical aperture areas and have a common center point. The receiver may to display to the operator the relative location of the field source or may direct the operator to a spot directly above the field source.11-18-2010

20100004754METHOD AND APPARATUS FOR USE OF POROUS IMPLANTS - An orthopedic prosthesis for implantation into a bone of a patient includes a porous metal shell adapted to be affixed within the bone. The porous metal shell includes an outer surface adapted to receive bone ingrowth and an inner surface adapted to engage a liner. The porous metal shell is porous from the outer surface to the inner surface. A non-porous member may be affixed to the porous metal shell. The non-porous member may include a piercing member extending from the outer surface, the piercing member adapted to penetrate the bone in an implanted position. The non-porous member may include spikes or fins. In one example, the piercing member may define a reduced material cross section at an interface with the outer surface of the porous metal shell. The piercing member may be adapted to be broken at the reduced material cross section and removed from the porous metal shell.01-07-2010
20100131068Porous Titanium Modular Revision Patella System - A patellar implant includes a posterior portion and an anterior portion. The posterior portion can have a first radial sidewall that extends between an outboard face and an inboard face. The outboard face can include an articulating surface. The inboard face can include one of a stem and a recess, and one of an annular central hub and an annular radial pocket. The anterior portion can have a second radial sidewall that extends between a tissue engaging surface and a posterior portion engaging surface.05-27-2010
20100174378Knee Joint Prosthesis System and Method for Implantation - A prosthesis system for replacing a knee joint between a femur and a tibia can include a femoral component, a tibial component, a bearing, a first yoke, and a first key. The femoral component can include a first condylar portion, a second condylar portion, a first sidewall extending superiorly from the first condylar portion, a second sidewall extending superiorly from the second condylar portion where the first and second sidewalls collectively comprise a first hinge portion. The tibial component can have a bone engaging inferior surface and a bearing engaging superior surface. The bearing can have an inferior that engages the bearing engaging surface and a superior femoral engaging surface. The bearing can define an opening. The first yoke can have an inferior portion, a superior portion and a yoke keyway extending through the therethrough.07-08-2010
