The virtual intelligence shoe with a podiatric analysis system provided with a portable pair of shoe-like body types thereof, into two of which a miniature electronic module and an enclosed sensor mat are permanently embedded in the shoe-like with a mechanical air package enclosing the electronic module to serve as a shock absorption. A miniature electronic module comprises a transmitting circuit with pressure resistance, shoe temperature and warning buzzer for full memory capacity, which receives the variable pressure and temperature voltage signals, convert them into resistance (ohm) and Celsius, respectively. The electrical signals can be emitted in an infrared light signal. An enclosed sensor mat constitutes a thin, flexible, planar, resilient, and dielectric material that arrays seventy-four positions at strategic geometrical pattern to produce the precision of collecting data exerted by a foot or feet continuously and instantaneously in static and dynamic event during the full weight bearing in various activities. The conjunction of a pair of shoe-like body types, a digital foot scanner, a portable infrared light-receiving unit and a central integrator (servers) form a podiatric analysis system for enabling accurate information. An obtained information of each individual can be stored and analyzed for diagnostic means with respect to the foot or feet maladies. The virtual intelligence shoe with a podiatric analysis system is an unconventional, which can ultimately be used by anyone and capable to produce consistent foot or feet information to implement the changes in the foot or feet biomechanics by altering the shoes, orthoses or other modes. In a preferred form, a pair of shoe-like body types is virtually applied to any type of foot or feet maladies and worn daily as if they were conventional shoes under various terrain conditions.

The technology of the 4D-GIS system deploys a GIS-based algorithm used to determine the location of a moving target through registering the terrain image obtained from a Moving Target Indication (MTI) sensor or small Unmanned Aerial Vehicle (UAV) camera with the digital map from GIS. For motion prediction the target state is estimated using an Extended Kalman Filter (EKF). In order to enhance the prediction of the moving target's trajectory a fuzzy logic reasoning algorithm is used to estimate the destination of a moving target through synthesizing data from GIS, target statistics, tactics and other past experience derived information, such as, likely moving direction of targets in correlation with the nature of the terrain and surmised mission.

Systems and methods which provide mapping an arbitrary outdoor environment and positioning a ground-based vehicle relative to this map. In one embodiment, a land-based vehicle travels across a section of terrain, recording both location data from sensors such as GPS as well as scene data from sensors such as laser scanners or cameras. These data are then used to create a high-resolution map of the terrain, which may have well-defined structure (such as a road) or which may be unstructured (such as a section of desert), and which does not rely on the presence of any “landmark” features. In another embodiment, the vehicle localizes itself relative to this map in a subsequent drive over the same section of terrain, using a computer algorithm that incorporates incoming sensor data from the vehicle by attempting to maximize the likelihood of the observed data given the map.

Systems, methods, and apparatuses for high-speed navigation. The present invention preferably encompasses systems, methods, and apparatuses that provide for autonomous high-speed navigation of terrain by an un-manned robot. By preferably employing a pre-planned route, path, and speed; extensive sensor-based information collection about the local environment; and information about vehicle pose, the robots of the present invention evaluate the relative cost of various potential paths and thus arrive at a path to traverse the environment. The information collection about the local environment allows the robot to evaluate terrain and to identify any obstacles that may be encountered. The robots of the present invention thus employ map-based data fusion in which sensor information is incorporated into a cost map, which is preferably a rectilinear grid aligned with the world coordinate system and is centered on the vehicle. The cost map is a specific map type that represents the traversability of a particular environmental area using a numeric value. The planned path and route provide information that further allows the robot to orient sensors to preferentially scan the areas of the environment where the robot will likely travel, thereby reducing the computational load placed onto the system. The computational ability of the system is further improved by using map-based syntax between various data processing modules of the present invention. By using a common set of carefully defined data types as syntax for communication, it is possible to identify new features for either path or map processing quickly and efficiently.

A two-dimensional focal plane array (FPA) is divided into sub-arrays of rows and columns of pixels, each sub-array being responsive to light energy from a target object which has been separated by a spectral filter or other spectrum dividing element into a predetermined number of spectral bands. There is preferably one sub-array on the FPA for each predetermined spectral band. Each sub-array has its own read out channel to allow parallel and simultaneous readout of all sub-arrays of the array. The scene is scanned onto the array for simultaneous imaging of the terrain in many spectral bands. Time Delay and Integrate (TDI) techniques are used as a clocking mechanism within the sub-arrays to increase the signal to noise ratio (SNR) of the detected image. Additionally, the TDI length (i.e., number of rows of integration during the exposure) within each sub-array is adjustable to optimize and normalize the response of the photosensitive substrate to each spectral band. The array provides for parallel and simultaneous readout of each sub-array to increase the collection rate of the spectral imagery. All of these features serve to provide a substantial improvement in the area coverage of a hyperspectral imaging system while at the same time increasing the SNR of the detected spectral image.

A method of navigating a medical device through a body of a patient includes providing a topography of at least a portion of the body, accepting user input defining a navigation path, robotically navigating the medical device to a starting point on the path, and robotically navigating the medical device along the navigation path to an endpoint. Waypoints defining the navigation path may be input on a graphical representation of the topography using a user interface such as a pointing device or touchscreen. The navigation path may also be defined by tracing a substantially continuous path on the graphical representation. A therapy may be administered while robotically navigating the medical device along the navigation path, either forward or in reverse, or while navigating the medical device along a return path defined by a plurality of virtual breadcrumbs generated as the medical device traverses the navigation path.

A pattern having exceptionally small features is formed on a partially fabricated integrated circuit during integrated circuit fabrication. The pattern comprises features formed by self-organizing material, such as diblock copolymers. The organization of the copolymers is directed by spacers which have been formed by a pitch multiplication process in which spacers are formed at the sides of sacrificial mandrels, which are later removed to leave spaced-apart, free-standing spacers. Diblock copolymers, composed of two immiscible block species, are deposited over and in the space between the spacers. The copolymers are made to self-organize, with each block species aggregating with other block species of the same type.
