  • Patent number: 7894997
    Abstract: A method of morphological reconstruction of biological activity in a tissue sample maps biological data resulting from analysis of tissue samples onto a 3-D morphological rendering of the biological sample. Each slice in a set of histological slices, indexed by a first index, is micro dissected into micro samples indexed by a pair of first and second indices.

  • Patent number: 7874591
    Abstract: An apparatus and method for canting a skier comprising a cant angle plate that locks on to the heel bearing surface of a ski binding. The cant angle plate has portions of varying thickness for inducing a cant angle when the heel of a boot rests on the cant angle plate locked on to the heel bearing surface of the binding. Thus, the cant angle plate alters the cant angle at which a boot supports a skier's foot and lower leg, relative to the longitudinal running surface or bottom plane of an attached ski.

  • Patent number: 7814157
    Abstract: A system is described which provides the capability for high-level extensible scripting language interpreters to incorporate and employ Web browser plug-ins as components within script-based programs. A script interpreter extension is described which simulates the plug-in API interface of a Web browser, from the point of view of the browser plug-in, to allow program scripts to cause browser plug-ins to be launched and manipulated, in a manner similar to the scripting platform's native widgets, from within the executing program script. This system allows embedded external program objects to be used to display and enable interactive processing of embedded data objects.

  • Patent number: 7720107
    Abstract: A source-synchronous parallel interface divides a wide data bus into clock-groups including a sub-group of the data lines and a clock line carrying a copy of the transmit clock. The traces in a clock-group are located physically close together to minimize skew between the signals carried on the traces of the clock-group. Deskew logic on the receiver compensates for skew between received clock-group signals.

  • Patent number: 7621636
    Abstract: In embodiments of optical arrangements of a working distance sensor in a fundus camera that can improve the determination of a correct working distance as well as the transverse positioning of the camera a number of near infrared light sources are arranged to project a number of near infrared illumination beams into the visible light illumination path of the fundus camera and a live view of the retina under near infrared illumination is captured and displayed on a monitor. These embodiments of optical arrangements and associated methods will enable an operator to directly determine if there is any undesirable flare or other artifact appearing within a designated region on the infrared retina view as a result of a wrong alignment of the fundus camera with respect to the eye in terms of not only the working distance but also the horizontal and vertical positions. Pattern recognition algorithms can be used to further enhance the positioning sensitivity of the working distance sensor.

  • Patent number: 7621638
    Abstract: A light delivery technique includes optical configurations as well as the associated methods that generate a ring beam from a linear light source. In one embodiment, a remote light source module delivers illumination light to a fundus camera and/or slit lamp. In another embodiment, an arrangement combines the use of a light pipe homogenizer and a ring beam transformer for efficiently collecting light from a substantially axially linear light source, homogenizing the collected light that lacks low angle flux relative to the optical axis, and transforming the light into a ring beam with a substantially improved low angle flux distribution. In still another embodiment, light emitted from a substantially axially linear light source is directly collected by a curved surface mirror and spatially filtered into a ring beam.
