20090287223 | REAL-TIME 3-D ULTRASOUND GUIDANCE OF SURGICAL ROBOTICS - Laparoscopic ultrasound has seen increased use as a surgical aide in general, gynecological, and urological procedures. The application of real-time three-dimensional (RT3D) ultrasound to these laparoscopic procedures may increase information available to the surgeon and serve as an additional intraoperative guidance tool. The integration of RT3D with recent advances in robotic surgery can also increase automation and ease of use. In one non-limiting exemplary implementation, a 1 cm diameter probe for RT3D has been used laparoscopically for in vivo imaging of a canine. The probe, which operates at 5 MHz, was used to image the spleen, liver, and gall bladder as well as to guide surgical instruments. Furthermore, the 3D measurement system of the volumetric scanner used with this probe was tested as a guidance mechanism for a robotic linear motion system in order to simulate the feasibility of RT3D/robotic surgery integration. Using images acquired with the 3D laparoscopic ultrasound device, coordinates were acquired by the scanner and used to direct a robotically controlled needle towards desired in vitro targets as well as targets in a post-mortem canine. The RMS error for these measurements was 1.34 mm using optical alignment and 0.76 mm using ultrasound alignment. | 11-19-2009 |

20090198877 | SYSTEM, CONTROLLER, AND METHOD FOR DATA STORAGE - A system, a controller, and a method for data storage are provided. The system includes a first storage unit, a second storage unit, and a controller. The first storage unit comprises a single-layer structure for storing data, and the second storage unit comprises a multi-layer structure for storing data. The controller is coupled to the first storage unit, the second storage unit, and a host and controls the host to set the first storage unit as a master storage device and set the second storage unit as a slave storage device. As a result, the host can recognize the first storage unit and the second storage unit as two independent storage devices for storing data. Thereby, the data storage process can be simplified. | 08-06-2009 |
20120166706 | DATA MANAGEMENT METHOD, MEMORY CONTROLLER AND EMBEDDED MEMORY STORAGE APPARATUS USING THE SAME - A data management method, a memory controller and an embedded memory storage apparatus are provided. The embedded memory storage apparatus has a plurality of physical blocks and each of the physical blocks has fast physical pages and slow physical pages. The method includes detecting a status of a state indication unit. The method further includes automatically reading data stored in the embedded memory storage apparatus, using the fast and slow physical pages of the embedded memory storage apparatus to re-store the data and marking status of the state indication unit as a second status when the status of the state indication unit is a first status. Accordingly, the storage space of the embedded memory storage apparatus can be efficiently used. | 06-28-2012 |

20090083476 | SOLID STATE DISK STORAGE SYSTEM WITH PARALLEL ACCESSSING ARCHITECTURE AND SOLID STATE DISCK CONTROLLER - A solid state disk (SSD) storage system with a parallel accessing architecture, including a SSD controller and a plurality of transmission interfaces of a predetermined bit number and bandwidth, and a solid state disk controller thereof are provided. The SD controller forms channels for transmitting control signals and data with one or more flash memories through each of the transmission interfaces. That is, independent transmission channels are constituted between the SSD controller, the transmission interfaces with multiple bits, and the flash memories. In one embodiment, the transmission interfaces are compatible with MMC 4.0 protocol or higher. Moreover, a host controls and accesses the flash memories through a SATA bus interface and the SSD controller, and uses a direct memory access (DMA) engine with a bidirectional connection port in the SSD controller to transmit data. | 03-26-2009 |

20080250192 | Integrating flash memory system - The present invention discloses an integrating data processing system. The system includes a master device with a host interface for processing data, at least one NAND flash memory unit having a unit interface, and a flash memory controller. For controlling access to the NAND flash memory unit, the flash memory controller is provided with a first interface connected with the host interface of the master device, and a second interface connected with the unit interface of the NAND flash memory unit. The first interface is identical to the unit interface of the flash memory and the second interface is identical to the host interface of the master device. The master device can access the NAND flash memory unit via the flash memory controller thereby facilitating to fit in with the development of new flash memory device without upgrading the original master device. | 10-09-2008 |
