Abstract:
In embodiments, an encoded micro pattern includes segments of encoded bits that can be optically-imaged by a digitizer. The position of each segment in the encoded micro pattern can be determined from the encoded bits in a segment. Each of the segments of the encoded micro pattern also includes a fiducial marker that indicates an orientation of a segment in the encoded pattern. The encoded bits of the encoded micro pattern can be integrated into a display surface of a display device, or integrated in a display screen that is positioned over the display surface of a display device.
Abstract:
In embodiments, a pen digitizer includes a light source that generates light. The pen digitizer also includes light guides, such as fiber optics, configured coaxial within the pen digitizer to transfer the light from the light source and focus the light around an imaging tip of the pen digitizer. A photo array optically-images reflected light from encoded bits in an encoded micro pattern, and a lens focuses the reflected light onto the photo array.
Abstract:
In accordance with an embodiment of the present invention, an image capture device comprises a first scanning module operable to scan a first side of an object and a second scanning module operable to scan a second side of the object, the first and second scanning modules translatable along their respective displacement paths.
Abstract:
A user input device for use with a computing device is provided. The user input device may include a housing with a bottom portion including a substrate that includes a transparent portion. The user input device may further include an optical tracking engine mounted in the housing proximate the substrate and being configured to transmit and/or detect light for tracking movement of the user input device through the transparent portion of the substrate.
Abstract:
A light guide includes at least two channels from which light is shined on a target area. The multiple channels disperse light across the target area more uniformly and with fewer dead or bright spots. The channels may be integral to one another, and may be molded. The light guide may further include an integral holder for supporting and aligning a LED light source to shine upon an entrance surface of the light guide. The entrance surface may also be formed as a collection lens. The channels may also be configured to direct light onto a target area at different angles. One or more of the channel faces from which light emanates may also be non-planar.
Abstract:
An x-ray laminography imaging system and a positioning system to be used therewith. The positioning system is configured to move the object in the X, Y and Z-directions (i.e., pitch and roll) to ensure that the object planes of the object that are being imaged are at least substantially parallel to the focal plane of the imaging system. The object is positioned so that object planes associated with the X, Y and Z-coordinates of points along the contour of the surface of the object are at least substantially parallel to the focal plane of the imaging system during imaging of the object plane. Because some objects, such as printed circuit boards, for example, are sometimes warped, by ensuring that the object plane being imaged is at least substantially parallel to the focal plane of the imaging system, precise laminographs are obtained. The preciseness of the laminographs ensures that the cross-sectional slices of the object are accurate, which improves the robustness of an inspection system that uses x-ray laminography to inspect objects.
Abstract:
An optical system for forming an image of at least a portion of an illuminated area on an object may comprise a lens positioned a spaced distance from the illuminated area on the object and an aperture stop positioned so that it is substantially co-planar with the image side focal plane of the lens. An occluding element is positioned between the lens and the illuminated area on the object so that the occluding element blocks a predetermined amount of light from a brightly illuminated region in the illuminated area but does not substantially block light from a less brightly illuminated region in the illuminated area.
Abstract:
A position sensing device has a substrate, a first portion, a second portion, a two-dimensional photosensor array, a light path and a lens. The first portion is attached to the substrate and the second portion is movably mounted to the first portion along a first axis. The two-dimensional photosensor array is attached to the second portion. The light path extends between a plane and the two-dimensional photosensor array. The lens is positioned in the light path.
Abstract:
A computer accessory according to one embodiment of the present invention may comprise a housing and an icon pointing system mounted within the housing. The icon pointing system generates icon pointing data during selected times in order to control a position of an icon associated with a host computer system connected to the computer accessory. An imaging system mounted within the housing produces image data during selected times, the image data being representative of an image of a selected object. A data transmission system operatively associated with the icon pointing system and the imaging system transmits the icon pointing data and the image data to the host computer.
Abstract:
A system and method of testing the quality of electronic device interconnections uses a pressure-sensitive medium. The interconnections of the electronic device are placed in contact with the pressure-sensitive medium. Force is then applied to the device so that an indication of the pressure exerted by each interconnection is produced by the pressure-sensitive medium. The indication of the pressure exerted by each interconnection is then analyzed to determine the quality of the connections of the electronic device.
