Abstract: A functional electrical stimulation (FES) device includes electrodes arranged to apply functional electrical stimulation to a body part of the user. FES stimulation is performed by: receiving values of a set of user metrics for the user; receiving a target position of the body part represented as values for a set of body part position measurements; determining a user-specific energization pattern for producing the target position based on the received target position and the received values of the set of user metrics for the user; and energizing the electrodes of the FES device in accordance with the determined user-specific energization pattern. The determination may utilize an FES calibration database with records having fields containing: values of the set of user metrics for reference users; energization patterns; and values of the set of body part position metrics for positions assumed by the body part in response to applying the energization patterns.

Abstract: Methods and apparatus are disclosed for guiding a camera user to take an appropriate set of component photographs to be stitched into a stitched panoramic photograph of a scene. In one example embodiment, the camera constructs and displays a video mosaic while the user sweeps the field of view of the camera over the scene. The camera computes the number and locations of a set of component photographs that will tile the scene, and then guides the user to sweep field of view of the camera over the scene a second time, visiting each component photograph location. A high-resolution component photograph may be taken at each location. Optionally, the camera gathers information from frames used to construct the video mosaic and uses the information to select settings for focus, exposure, or both to be used during the taking of the component photographs.

Abstract: An illumination system for illuminating a scan region on an object may comprise a hollow reflector having an interior reflective surface and an exit aperture. A light source positioned within the hollow reflector produces a plurality of light rays, some of which are reflected by the interior reflective surface of the hollow reflector before passing through the exit aperture. First and second reflectors positioned adjacent respective first and second sides of the exit aperture of the hollow reflector at least partially collimate light passing through the exit aperture of the hollow reflector to form a collimated beam.

Abstract: A method is disclosed for achieving correct exposure, focus, or both in a panoramic photograph that is stitched together from component photographs. In one example embodiment, a camera user sweeps the camera across the scene to be photographed, at least two measurements of scene portion brightness are made during the sweep, the brightness measurements are combined, and camera exposure settings are chosen based on the combination.

Abstract: A method is disclosed for measuring distance from a camera to parts of a scene using a characterization of perspective distortion in a photograph of the scene. In one example embodiment, a first distance measurement is obtained from the camera to a first point in the scene, the perspective distortion is characterized, and the distance to at least one other point on a plane in the scene is computed based on the first distance measurement and the perspective characterization.

Abstract: A method removes distortion induced by camera tilt from a digital representation of a photograph taken with a rotational or swing-lens panoramic camera.

Abstract: A transparent media adapter for scanning transmissive media on a flatbed scanner comprises a fiber optic face plate. The fiber optic face plate translates the image from the media to the scanner focal plane.

Abstract: A scanner is provided with a variable aperture lens system. High resolution scans use a relatively small aperture size, and scanning speed is relatively slow. Low resolution scans use a relatively large aperture size, and scanning speed is increased. Fast scans are limited to lower sampling rates, which in turn permit more optical blurring relative to high sampling rates. Accordingly, the incremental cost of the larger aperture is minimized by permitting the lens aberrations specifications to be relaxed at larger apertures. Preferably, an electronic variable aperture is provided, for example, by use of electronically controlled polarization plates or by use of electrochromic substances.

Abstract: A system and method are disclosed for distributing and presenting preferred data from a host server to a display device located at a predetermined remote premise through a communications network. The method involves identifying a user preference, providing at least one data feed containing information related to the user preference, selecting preferred data from the data feed corresponding to the user preference, pre-loading information that matches the preferred data from the host server to the display device, and presenting the preferred data through the display device.

Abstract: An apparatus for mounting an object precisely in a specific plane. An object is mounted on small support points rather than flat pads or other flat surfaces. The support points are stiff but not completely rigid. Exactly four support points are used. Mechanical forces are sufficient to slightly compress the two higher support points on a diagonal and to slightly compress the object so that the object presses against all the support points, with a higher amount of compression for one pair of diagonal points relative to the other two points. In an example embodiment, the support points are formed at the intersection of curved surfaces or at the intersection of multiple planar surfaces. In a specific example embodiment, the points are formed at the intersection of cylindrical surfaces. The points are fabricated by a cylindrical cutting bit that has partial-cylinder grooves formed circumferentially in the bit.

Abstract: An image capture device, such as a scanner, is built including hardware necessary to capture both reflective and transmissive image data from a transparency. The device may associate the two types of data internally or rely on other hardware, such as a controlling computer, to do the association of the two quantities of data. In one possible embodiment, the device would include the ability to perform optical character recognition (OCR) of the reflective data (or the transmissive data, if desired), converting to a type of text format any printing on the transparency.

Abstract: A simple, inexpensive apparatus is disclosed for measuring position in a robotic mechanism. A light source illuminates a reflective target, and a light detector views the target, sensing light reflected from the target. By virtue of the characteristics of the light source, the shape and material of the target, and the arrangement of the light source, target, and detector, the intensity of light received by the detector varies with the relative position of the mechanism and the target. Optionally, a tube limits the field of view of the detector. The detector may be moved until a local maximum is found for the reflected light from the target. A method of operating the apparatus is also disclosed.

Abstract: By scanning both sides of a photographic print, data from the back of the print may be associated with the image. If the backside data includes text, optical character recognition (OCR) techniques optionally may be used to convert the image of the back of the photo into text that may be included in a database or other data structure allowing the text to be associated with the photographic image. This allows the user to quickly and easily search a large database of images for either a specific image or a group of images according to some set of search criteria.

Abstract: A motion control system comprises both a stepper motor and a DC motor. The motors are coupled, and may be operated independently or in concert for various scan types. The stepper motor may be used as an encoder for measuring the position of the mechanism.
