The present invention embodiments include a geographic overlay system including an information system, a mapping system interface to communicate with a mapping system and a database system including National Census geographic boundaries and data files. The geographic overlay system utilizes a client/server model that streams geographic data from a server system to dynamically render vector-based map layers inside a client browser. The geographic overlay system employs a Nationwide database of Census geographies that may be rendered as interactive point, line or polygon objects over a National base map provided by the mapping system. A database builder interface enables users to build the database and server pages. The present invention embodiments overlay translucent, interactive dynamically generated vector-based polygonal Census boundary map layers over geographical maps from the mapping system. The overlaying vector map layers perform thematic analysis, enable information retrieval, display mouse-over tool-tips and query a dynamic block-level National spatial-relational database.

An automated method and/or system for identifying suspected lesions in a brain is provided. A processor (a) provides a magnetic resonance image (MRI) of a patient's head, including a plurality of slices of the patient's head, which MRI comprises a multispectral data set that can be displayed as an image of varying pixel intensities. The processor (b) identifies a brain area within each slice to provide a plurality of masked images of intracranial tissue. The processor (c) applies a segmentation technique to at least one of the masked images to classify the varying pixel intensities into separate groupings, which potentially correspond to different tissue types. The processor (d) refines the initial segmentation into the separate groupings of at least the first masked image obtained from step (c) using one or more knowledge rules that combine pixel intensities with spatial relationships of anatomical structures to locate one or more anatomical regions of the brain. The processor (e) identifies, if present, the one or more anatomical regions of the brain located in step (d) in other masked images obtained from step (c). The processor (f) further refines the resulting knowledge rule-refined images from steps (d) and (e) to locate suspected lesions in the brain.

A technique of generating a stereoscopic panorama image includes panning a portable camera device, and acquiring multiple image frames. Multiple at least partially overlapping image frames are acquired of portions of the scene. The method involves registering the image frames, including determining displacements of the imaging device between acquisitions of image frames. Multiple panorama images are generated including joining image frames of the scene according to spatial relationships and determining stereoscopic counterpart relationships between the multiple panorama images. The multiple panorama images are processed based on the stereoscopic counterpart relationships to form a stereoscopic panorama image.

One embodiment of the present invention provides a system that uses Radio Frequency Identification (RFID) tags to determine the position of an object. During operation, the system receives signals from an array of RFID tags at an RFID tag reader, wherein a mask of known size and shape is interposed between the array of RFID tags and the RFID tag reader, thereby obscuring signals from a subset of the RFID tags. Next, the system determines the position of the object by analyzing the pattern of obscured RFID tags, wherein the analysis is based on a known spatial relationship between the object, the mask and the array of RFID tags.

A bendable bone plate (10) is disclosed which is adapted for use in situ as a conformable bone splint to fix the spatial relationship of at least two bone parts (80). The bone plate (10) has an elongated plate (11) made of a bendable material. A plurality of screw apertures (24) extending through the top (14) and bottom (16) surfaces are disposed along the length (L) of the plate. Bone screws (28) are inserted through the apertures into the underlying bone parts (80) to anchor the elongated plate (11) to the bone parts (80). At least two of the screw apertures (24) are disposed as a closely spaced pair (40) of screw apertures (24) with a “bend relief zone” (60) disposed between the closely spaced apart screw apertures (24). The bend relief zone (60) is disposed to allow the elongated plate (11) to be bent across the bend relief zone (60) up to a certain angle (A) without deforming the screw apertures (24) adjacent the bend relief zone (60)

A dispensing system is disclosed which utilizes an electronically powered key device and/or identification code associated with a refill container to preclude the need for mechanical keys. The system utilizes a near field frequency response to determine whether a refill container is compatible with a dispensing system. In particular, the refill container is provided with a coil terminated by one of a number of capacitors. The container is received in a housing that provides a pair of coils that are in a spatial relationship with the installed refill container's coil. By energizing one of the housing's coils, the other coil detects a unique electronic signature generated by the container's coil. If the signature is acceptable, the dispensing system is allowed to dispense a quantity of material. The system also provides a unique latching mechanism to retain the container and ensure positioning of all the coils.

Techniques for improving treatment delivered to a target site in a patient include delivering a treatment from a treatment delivery device to a target site in a patient supported by a patient support structure. During the delivery of treatment, a state of the patient is measured to produce real-time measurement data. Measuring the state is non-invasive; and the measured state is a correlated surrogate for position of the target site. Compensating movement data is determined based on the real-time measurement data to cause the target site to maintain a particular spatial relationship with the treatment delivery device. Either the treatment delivery device, or the support structure, or both, are moved based on the compensating movement data. When the delivery device alone is moved, the correlation between measured state and target site is based on partial least squares applied to pre-treatment measurements of both.
