One embodiment of the invention is directed to an imaging probe which comprises a first element supplying electromagnetic radiation in a forward path for illuminating a forward field of view of space in front of the probe, a second element supplying electromagnetic radiation in a sideways and / or rearward path for illuminating a sideways and / or back field of view of space alongside the probe and an image sensor. The probe further includes an imaging device in imaging paths imaging the forward and sideways and / or back fields of view onto the image sensor. Preferably the forward path, the sideways and / or rearward path and the imaging paths are unobstructed by any component of the probe. Preferably the forward and sideways and / or back fields of view are registered in a fixed spatial relationship relative to one another on the image sensor. This probe can also be used with existing endoscopes or laparoscopes so that it will be easily merged into current instruments of different manufacturers, making it easier and cheaper to use this product without the expense of a totally new endoscopy or laparoscope platform. This probe can also be used to image objects in inanimate environments as well, such as in containers, buildings, rooms, engines and pipes.

A method positions a profile of a prosthetic component on the three-dimensional model of a limb. Patient-specific anatomical data of the limb is gathered. First and second anatomical landmarks are identified to determine a first spatial relationship. A third anatomical landmark is identified to determine a second spatial relationship with respect to the first spatial relationship. The profile of the prosthetic component is positioned in all but one degree of freedom. A fourth anatomical landmark is identified to position the profile of the prosthetic component in the one remaining degree of freedom.

A pedestrian navigation and spatial relation device including a position finder, a spatial relationship sensor, an input mechanism, and an output mechanism. The position finder can be configured to determine a geographic position of the device based upon received wireless signals. The spatial relationship sensor can provide data used to detect a position of at least one obstacle relative to the device. The input mechanism can specify a destination location. The output mechanism can present device output to a user. The device output can include sensory indicators for at least one of guiding a pedestrian to the destination location and warning a pedestrian about the detected obstacles.

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.

A content-based image retrieval (CBIR) system has a front-end that includes a pipeline of one or more dynamically-constructed filters for measuring perceptual similarities between a query image and one or more candidate images retrieved from a back-end comprised of a knowledge base accessed by an inference engine. The images include at least one color set having a set of properties including a number of pixels each having at least one color, a culture color associated with the color set, a mean and variance of the color set, a moment invariant, and a centroid. The filters analyze and compare the set of properties of the query image to the set of properties of the candidate images. Various filters are used, including: a Color Mask filter that identifies identical culture colors in the images, a Color Histogram filter that identifies a distribution of colors in the images, a Color Average filter that performs a similarity comparison on the average of the color sets of the images, a Color Variance filter that performs a similarity comparison on the variances of the color sets of the images, a Spread filter that identifies a spatial concentration of a color in the images, an Elongation filter that identifies a shape of a color in the images, and a Spatial Relationship filter that identifies a spatial relationship between the color sets in the images.

The present invention provides a method whereby the spatial relationship and orientations of one or more three-dimensional objects being illuminated by an optical projector, and the optical projector itself, can be very accurately defined both quickly and easily. The present invention also provides a novel computerized optical projection system whereby three dimensional data when viewed by the human eye projected onto three dimensional objects is not deformed as a result of the non-planar projection surface. The present invention could have many applications in many industries that include entertainment, apparel, marketing, and many others. In one embodiment, the invention provides computerized optical assembly or manufacturing guidance systems, and related methods, that provide step-by-step assembly or manufacturing instructions for instructing technicians how to assemble or manufacture three-dimensional objects or systems, or parts thereof, which may be extremely complex, such as an aircraft, or a part thereof (a vertical stabilizer, or the like), in a very efficient, rapid and accurate manner. The assembly instructions are in the form of calibrated three-dimensional text, images and / or symbols, and are projected by one or a plurality of optical projectors that are in operable communication with one or a plurality of computers onto the three-dimensional objects or systems, or component parts or skins thereof.
