A system and method for dynamic zoom adjustment based, in part, upon: the raster data in the user selected local area is disclosed; and/or the knowledge of a prevailing font size in a user selected region such that the text in that region is enlarged to be just readable. To achieve this, the detail in the local area is examined and a zoom factor is calculated that depends on the image detail and/or the viewing screen resolution. A document server may be employed to develop the information needed to enable this functionality. In one embodiment, the information is developed by RIPping the document, and then storing a spatial map of localized details (e.g., font sizes at several display resolutions) to automatically adjust a zoom level or factor and thereby facilitate navigation and reading.

Systems, methods and devices for determination of disease class scores for patient tissue are disclosed. The disease class scores may be based on the probability or probability-like metric for a disease condition or outcome.

A method and system for displaying predictions on a spatial map includes using a data analyzer for analyzing heterogeneous data having a spatial component to find utilizable data and using machine learning to automatically extract relationships from the utilizable data. The extracted relationships are used to make a prediction about at least one location on the spatial map and present that prediction in an oblique or perspective view. An interface presents the prediction on the spatial map in the form of a heat map overlying a 3-D topographical map. Although the 3-D map can be shown as any form of graphical projection including an oblique projection or orthographic projection, preferably a perspective view is used. It is also preferred that the graphical projection be interactive. The heat map may be 2-D or 3-D and be selectively displayed depending on the preference of a user.

A system and method of dynamically localizing a measurement of parameter characterizing tissue sample with waves produced by spectrometric system at multiple wavelengths and detected at a fixed location of the detector of the system. The parameter is calculated based on impulse response of the sample, reference data representing characteristics of material components of the sample, and path lengths through the sample corresponding to different wavelengths. Dynamic localization is effectuated by considering different portions of a curve representing the determined parameter, and provides for the formation of a spatial map of distribution of the parameter across the sample. Additional measurement of impulse response at multiple detectors facilitates determination of change of the measured parameter across the sample as a function of time.

Spatial mapping of wireless access point service area. A means is presented by which a WACN's (Wireless Access Control Node's) service area is spatially mapped providing information corresponding to coverage region(s) within the WACN's service area. This spatial mapping may be generated and stored within either communication device at either end of a communication link (e.g., in a WACN or in a communication device operable to connect to the WACN). From the WACN's perspective, the spatial map can include its one or more coverage regions within its service area. From a communication device's perspective (e.g., a communication device that is capable to connect to a WACN), the spatial map can include multiple service areas provided by multiple WACNs and the various coverage regions therein. The partitioning of a WACN's service area into coverage areas can be performed along various lines (e.g., signal strength, history of connectivity, operational parameters employed, etc.).

A device is configured for interrogating a blood vessel to derive flow characteristics (S628) and for, responsive to the deriving and based on the derived characteristics, anatomically identifying the vessel. A spatial map of the vessels may be generated based on the interrogating, and specifically the Doppler power computed from data acquired in the interrogating. Subsequent interrogating (S668) may occur, based on the map and on a user-selected set of vessels and/or vessel categories, to derive clinical Doppler indices. The device can be designed to automatically set a sample volume (509) for the subsequent interrogating, and to operate automatically from the user selection to display of the indices. The display may further include an image (524) of the vessels summoned by the set, annotated by their individual anatomical names, and optionally a diagnosis relating to blood flow. The displayed image may be enlarged to zoom in on the user's onscreen selection. The device may feature a two-dimensional ultrasound non-phased array of transducer elements.

The invention discloses a mobile robot autonomous navigation method based on combined navigation and feature point matching, and the steps are as follows: S1, establishing a spatial map database; S2,planning a path; S3, obtaining position information of a mobile robot; S4, performing Kalman filtering iteration; and S5, correcting the inertial navigation of the mobile robot. Autonomous navigationbased on combined navigation and feature point matching is to use laser radar to scan and model the surrounding environment, extract the surrounding feature points, determine the location of the distance feature points, and then calculate the current position of the robot in the map according to the location of the feature points in the known map, so as to determine the position coordinates to compensate for the blocking out of the GPS signal of the patrol robot.

A medium of interest is interrogated according to ultrasound elastography imaging. A preliminary elasticity-spatial-map is formed. This map is calibrated against a reference elasticity-spatial-map that comprises an array (232) of different (240) elasticity values. The reference map is formed to be reflective of ultrasonic shear wave imaging of a reference medium. The reference medium is not, nor located at, the medium of interest, and may be homogeneous. Shear waves that are propagating in a medium are tracked by interrogating the medium. From tracking locations on opposite sides of an ablated-tissue border, propagation delay of a shear wave in the medium and of another shear wave are measured. The two shear waves result from respectively different pushes (128) that are separately issued. A processor decides, based on a function of the two delays, that the border crosses between the two locations. The calibrated map is dynamically updated and may include post-ablation border expansion (346) and time-annotated previous stages (344, 348).

A method is provided for measurement of dispersion or other optical and mechanical properties within a waveguide by inducing four-photon mixing at different locations within the waveguide by timing a pump signal to counter-collide with and abruptly amplify or attenuate one or both of a probe pulse and a signal pulse at each location. The measurement of the components of the resulting mixing signal created by each collision is used to calculate dispersion defined by the location at which the collision occurred. By combining the measurements from all of the locations, a spatial map of dispersion or other optical or mechanical properties within the waveguide can be generated.
