Processing of deterministic user-defined functions using multiple corresponding hash tables
A deterministic UDF processing mechanism processes user-defined functions (UDFs) using multiple hash tables. Data access patterns for a UDF are collected, and an appropriate hash table set is then determined for the UDF from the data access patterns. If a UDF accesses some similar columns and some disjoint columns, the similar columns are grouped together, and one or more hash tables are allocated to the similar columns. Disjoint columns are allocated their own hash tables. In addition, the allocation of hash tables may be adjusted based on historical access patterns collected over time. By dynamically allocating and adjusting sets of hash tables to a deterministic UDF, the performance of the UDF is greatly increased. |

Efficient XML schema validation of XML fragments using annotated automaton encoding
An XML schema is compiled into an annotated automaton encoding, which includes a parsing table for structural information and annotation for type information. The representation is extended to include a mapping from schema types to states in a parsing table. To validate a fragment against a schema type, it is necessary simply to determine the state corresponding to the schema type, and start the validation process from that state. When the process returns to the state, fragment validation has reached successful completion. This approach is more efficient than a general tree representation. Only the data representation of the schema information is handled, making it much easier than manipulating validation parser code generated by a parser generator. In addition, only one representation is needed for schema information for both document and fragment validation. This approach also provides a basis for incremental validation after update. |

Representation of order in multiple markets
A trading process represents an order that it is handling at multiple market processes simultaneously. Each of the market processes and the trading process follow a two-phase commit protocol, wherein permission to execute the order is obtained from the process controlling the order, and then the order is executed. Accordingly, multiple executions of an order are prevented. The control process is typically the trading process that originated the order. However, in some market methodologies, the market process may assume control over the order. Permission to execute the order is explicitly given by a trading process. Permission to execute the order may be inferred after a market process determines that no other market processes have control over the order. |

Fast 3D-2D image registration method with application to continuously guided endoscopy
A novel framework for fast and continuous registration between two imaging modalities is disclosed. The approach makes it possible to completely determine the rigid transformation between multiple sources at real-time or near real-time frame-rates in order to localize the cameras and register the two sources. A disclosed example includes computing or capturing a set of reference images within a known environment, complete with corresponding depth maps and image gradients. The collection of these images and depth maps constitutes the reference source. The second source is a real-time or near-real time source which may include a live video feed. Given one frame from this video feed, and starting from an initial guess of viewpoint, the real-time video frame is warped to the nearest viewing site of the reference source. An image difference is computed between the warped video frame and the reference image. The viewpoint is updated via a Gauss-Newton parameter update and certain of the steps are repeated for each frame until the viewpoint converges or the next video frame becomes available. The final viewpoint gives an estimate of the relative rotation and translation between the camera at that particular video frame and the reference source. The invention has far-reaching applications, particularly in the field of assisted endoscopy, including bronchoscopy and colonoscopy. Other applications include aerial and ground-based navigation. |

Method and apparatus for scalable compression of video
The present invention relates to a method and apparatus for producing a fully scalable compressed representation of video sequences, so that they may be transmitted over networks, such as the Internet, for example. Because the signal is scalable, users receiving the signal can obtain the signal at the appropriate resolution and quality that their system will handle or that they desire.The invention implements a “motion compensated temporal wavelet transform” in order to enable compression of the video in a scalable fashion while still taking advantage of inter-frame redundancy in a manner which is sensitive to scene and camera motion.The motion compensated temporal wavelet transform is implemented by decomposing the video sequence into a set of temporal frequency bands and then applying a sequence of motion compensated lifting operations to alternately update an odd frame sub-sequence based upon an even sub-sequence and vice versa in a manner which is sensitive to motion. |

Ultrasound transmit beamformer integrated circuit and method
The invention provides a novel method of transmit beamforming, which allows compact analog implementation of complex digital algorithms without compromising their features. It is aimed to support envelope shaping, apodization, and phase rotation per channel and per firing. Each of three embodiments represents a complete transmit channel driven by pulse-width modulated (PWM) waveforms stored in a conventional sequence memory. PWM signals controls the transmit pulse envelope (shape) by changing the duty cycle of the carrier. Beamformation data are loaded prior to a firing via serial interface. Under the direction of a controller, the circuitry allows high precision (beyond sampling rate) phase rotation of the carrier. It also provides transmit apodization (aperture weighting), which maintains an optimal trade-off among low sidelobe level and widening of the mainlobe. Implementing such an IC, the manufacturing cost of a high-end ultrasound system can be reduced. Equally, the proposed solution makes the benefits of digital transmit beamformers available to midrange and entry-level machines since it merely requires a modified programming of the sequence memory. |

Operating frequency reduction for transversal FIR filter
A method and system for reducing the frequency of operation for a transversal Finite Impulse Response (FIR) filter is disclosed. In the preferred embodiment, the transversal filter operates in such a way that it has an even and odd row of data, which are latched on rising and falling edges of the clock respectively. This allows the clock frequency to be reduced by a factor of 2, and thus allows the use of more power efficient latches. A reduction in the frequency of operation causes the high speed latches within the transversal filter to hold the data bits twice as long as is required, which changes the desired impulse response of the FIR filter. A circuit is required to select the appropriate data bits from the output of the appropriate half-speed latch, and subsequently scale it to apply the co-efficient gain. Each of the subsystems is analog, and operates in accordance with a synchronous clock system. In a more general embodiment of the invention, the data is provided to Q shift registers that operate at a clock rate which is reduced by a factor of Q. |

In calculating the bandwidth availability information, the extended reservation protocol accounts for not only the amount of bandwidth reserved on each of links via the resource reservation protocol itself, but also for the bandwidth usage by other traffic on the links, such as Label Distribution Protocol (LDP) traffic or Internet Protocol (IP) traffic. The routers exchange bandwidth availability information using a routing protocol to gain network-wide knowledge of bandwidth availability. |

Fused lead wire for ballast protection
A ballast having fused leads protects against uncommon, but harmful, ballast failures. The fused leads prevent a current in the primary coil of the ballast from exceeding a potentially damaging value. A thermal protector shorts the primary ballast coil if the temperature of the secondary ballast coil exceeds a potentially damaging value. Since the thermal protector permanently disables the ballast, potentially damaging repetitive overheating of the ballast is prevented. |
