20090105732 | Mechanical apparatus and method for delivering materials into the inter-vertebral body space for nucleus replacement - The present invention relates to a device and method to perform 1) disk fusing, 2) an artificial replacement of the nucleus, 3) artificial replacement of the annulus, or 4), an artificial replacement of both the nucleus and annulus. The device is designed to be placed into the inter-vertebral space following discectomy. The invention includes a delivery catheter and an expandable continuous mesh that has a torus configuration with a lumen within the mesh and a center hole. The mesh can be diametrically expanded in diameter into the disc space whereby various materials can be injected into the lumen and/or the center hole. | 04-23-2009 |
20120071802 | Systems, Devices, and Methods for Mechanically Reducing and Fixing Bone Fractures - A fracture reduction is mechanically achieved by supporting a body region having the bone fracture on a frame. A first reduction mechanism on the frame is operated to apply to the bone fracture a first predefined force reduction vector that returns the bone fracture to a corrective alignment in a first anatomic orientation, while also mechanically maintaining the corrective alignment in the first anatomic orientation. Independently, a second reduction mechanism on the frame is operated to apply a second predefined force reduction vector that returns the bone fracture to a corrective alignment in a second anatomic orientation different than the first anatomic orientation without altering the corrective alignment in the first anatomic orientation, while mechanically maintaining the corrective alignment in the second anatomic orientation. The fracture reduction is mechanically fixed by mechanically guiding the placement at least one bone fixing device into the reduced bone fracture. | 03-22-2012 |
20120285472 | SYSTEMS, DEVICES, AND METHODS FOR MECHANICALLY REDUCING AND FIXING BONE FRACTURES - Bone fracture reduction devices, systems, and methods couple to a patient platform a mechanical bone fracture reduction fixture, which is sized and configured to be conveyed separate from the patient platform. The bone fracture reduction fixture carries an array of mechanical force reduction assemblies that are sized and configured to independently mechanically manipulate a fractured bone region. Each mechanical force reduction assembly functions independently of the other mechanical force reduction assemblies, to independently apply and maintain one of the prescribed mechanical reduction forces to the fracture and also mechanically reduce the fracture in the desired reduction planes. | 11-15-2012 |
20120289879 | SYSTEMS, DEVICES, AND METHODS FOR MECHANICALLY REDUCING AND FIXING BONE FRACTURES - A frame is sized and configured to support a reduced bone fracture of an individual. A guide assembly on the frame carries a bone fixing device guide that defines a guide path along which a bone fixing device can be advanced into a region of the reduced bone fracture. A linkage system couples the bone fixing device guide to the frame for articulation of the guide path among a plurality of desired orientations with respect to the reduced bone fracture. A guide bushing is included. Which includes packaging that maintains the guide bushing in a sterile condition prior to insertion into the bone fixing device guide. | 11-15-2012 |
20120303030 | SYSTEMS, DEVICES, AND METHODS FOR MECHANICALLY REDUCING AND FIXING BONE FRACTURES - An array of mechanical force reduction assemblies sized and configured to independently mechanically manipulate a fractured bone region. Each assembly functions independently of the other assemblies, to apply and maintain one of the prescribed mechanical reduction forces to the fracture, to thereby mechanically reduce the fracture in a desired way. A carrier coupled to the assembly accommodates temporary attachment of an orthotic brace, residing thereon, partially or fully assembled in a region of the bone fracture. A linkage mechanism accommodates the rotational articulation of the brace in response to the application of one or more mechanical force vectors, to move the bone fracture into a desired anatomic orientation. A locking mechanism maintains the orientation of the brace to maintain the desired anatomic orientation. After release from the carrier, the brace serves in an ambulatory fashion to maintain the desired anatomic orientation after reduction and as healing occurs. | 11-29-2012 |

20080215808 | RAID CONTROLLER USING CAPACITOR ENERGY SOURCE TO FLUSH VOLATILE CACHE DATA TO NON-VOLATILE MEMORY DURING MAIN POWER OUTAGE - A write-caching RAID controller includes a CPU that manages transfers of posted-write data from host computers to a volatile memory and transfers of the posted-write data from the volatile memory to a redundant array of storage devices when a main power source is supplying power to the RAID controller. A memory controller transfers the posted-write data received from the host computers to the volatile memory and transfers the posted-write data from the volatile memory for transfer to the redundant array of storage devices as managed by the CPU. The memory controller flushes the posted-write data from the volatile memory to the non-volatile memory when main power fails, during which time capacitors provide power to the memory controller, volatile memory, and non-volatile memory, but not to the CPU, in order to reduce the energy storage requirements of the capacitors. During main power provision, the CPU programs the memory controller with information needed to perform the flush operation, such as the location and size of the posted-write data in the volatile memory and various flush operation characteristics. | 09-04-2008 |
20110239021 | Memory calibration method and apparatus for power reduction during flash operation - A method for providing reduced power consumption in a computer memory system is provided. The method includes calibrating, by a processor, a volatile memory of the computer memory system at a first and a second operating speed, where the second operating speed is higher than the first operating speed. The method also includes operating, by a memory controller coupled to the processor and the volatile memory, the volatile memory at the second operating speed if a main power source provides power to the computer memory system. The method further includes operating, by the memory controller, the volatile memory at the first operating speed if a backup power source provides power to the memory controller and the volatile memory. The backup power source provides power to the memory controller and the volatile memory when there is a loss of main power to the computer memory system. | 09-29-2011 |
20110239043 | Buffer management method and apparatus for power reduction during flash operation - A method for providing reduced power consumption in a computer memory system is provided. The method includes transferring, by a memory controller coupled to a volatile memory, a non-volatile memory, and a buffer, first data from the volatile memory to the buffer. The buffer stores less data than the volatile memory and the non-volatile memory. The method also includes placing the volatile memory into self-refresh mode after transferring the first data to the buffer. The method further includes conveying the first data from the buffer to the non-volatile memory, where the amount of first data exceeds a predetermined threshold. While conveying the first data, the memory controller takes the volatile memory out of self-refresh mode when the amount of first data in the buffer reaches the predetermined threshold. The volatile memory is ready to transfer second data to the buffer when the memory controller is finished transferring the first data. | 09-29-2011 |
