| 20090118608 | METHODS AND APPARATUSES FOR ESTIMATING THE ELLIPTICAL CONE OF UNCERTAINTY - A magnetic resonance imaging scanner acquires diffusion-weighted imaging data. A reconstruction engine reconstructs the acquired diffusion-weighted imaging data into diffusion-weighted image representations. A diffusion tensor engine constructs a diffusion tensor map of an area of an interest of a subject. An eigenvalue/eigenvector ordering engine obtains and orders eigenvectors and eigenvalues at each voxel. A covariance matrix determining engine constructs a covariance matrix of a major eigenvector of each voxel. A first normalized measure determining engine computes a first normalized measure. A second normalized measure determining engine computes a second normalized measure. A rendering engine generates a human-viewable display of an image representation. | 05-07-2009 |

| 20100202294 | NETWORK CONGESTION MANAGEMENT SYSTEMS AND METHODS - Systems, methods and software useful for overcoming network congestion problems including head-of-line blocking issues and other network congestion problems. In certain aspects, flow control mechanisms implemented in a switch device or other network device manage buffer and system level resources using a scheduler to control the amount of data requested from a local SAN fabric. Switches and other network devices configured according to the present invention monitor each individual SCSI task, and are configured to apply flow control measures to each active session when buffering resources become scarce, such as when buffering data for a slower-speed WAN link or TCP/IP based interconnects of any speed. | 08-12-2010 |

| 20100274247 | Bone Plate - A bone plate has an upper surface, a lower surface, and at least one first hole extending through the upper and lower surfaces. The first hole has two or three vertically separate regions, each region communicating with or abutting the adjacent region. The first hole has a first upper region, which is unthreaded and which, from the plate's upper surface to the plate's lower surface, has a curved inward taper. The first hole has a second middle region, which is threaded and which, from the plate's upper surface to the plate's lower surface, has a conical inward taper. The first hole has a third lower region, which is unthreaded and which, from the plate's upper surface to the plate's lower surface, has a conical outward taper. The bone plate is straight, curved, or both straight and curved. The bone plate may have at least one second hole, different from the first hole. The second hole is an elongated hole, which has a compression ramp or which has a threaded portion through part of its perimeter and a non-threaded portion through the other part of its perimeter. | 10-28-2010 |

| 20100145169 | METHODS AND SYSTEMS FOR DETECTING A CONDITION OF COMPARTMENT SYNDROME - Methods and systems for detecting and alerting one to a condition of Compartment Syndrome provide for determining concentration data of biochemical compounds in tissues, preferably at a shallow depth beneath the skin; analysing the concentration data to detect a condition of Compartment Syndrome; and triggering an alarm if a condition of Compartment Syndrome is detected. The concentration of biochemical compounds may be measured using Near Infrared Spectroscopy. The biochemical compounds may comprise at least one compound from the group consisting of Hemoglobin, Oxygenated Hemoglobin, Cytochromes and Myoglobin. | 06-10-2010 |

| 20100084557 | LIGHT INTENSITY CONTROL FOR NEAR INFRARED SPECTROSCOPY - A system for near infrared spectroscopy includes a controller that automates selection of light intensities for one or more light sources. The system may stepwise increase or decrease a current driving a light source until a signal received at a light detector is within a desired range. The system may maintain closed loop control over the intensity of a light source after the intensity has been set. The closed loop control may be based on a signal from a second light detector that senses light from the light source. Current/intensity settings may be established for each of multiple light detectors. In response to selection of a light detector, the corresponding current may be delivered to drive the light source. | 04-08-2010 |
| 20100127627 | LIGHT-EMITTING MEDICAL DEVICES HAVING PROTECTIONS AGAINST UNINTENDED LIGHT EXPOSURE - Apparatus and methods are provided for guarding against unintended exposure to light from a light-emitting device used to direct light to a subject for detection by a light detector. A sensor signal indicative of light detected by the light detector is sampled. An inhibition signal for inhibiting emission of light from the light-emitting device is generated, based at least in part on whether emitted light is expected from the light-emitting device and the comparison of the sampled sensor signal value to a threshold value. The light-emitting device may be monitored for continuous wave operation. A mechanical interlock may be provided having a guard moveable between closed and open positions respectively to cover and expose a port of the light-emitting device. | 05-27-2010 |

| 20100061166 | DYNAMIC REAL-TIME DELAY CHARACTERIZATION AND CONFIGURATION - In mask programmable integrated circuit, such as a structured ASIC, a delay chain provides a delay that is set by a mask programmable switch. The delay chain receives an input to allow the delay mask programmed delay to be overridden using a JTAG controller. This allows testing of different delays. The input may also be provided by a fuse block, so that the fuse block can override the mask programmable switch, thus allowing a delay to be changes after mask programming. | 03-11-2010 |
