  • Patent number: 8797395
    Abstract: An automated system for inspecting a porous substrate using a sample, comprising, a delivery device positioned to apply the sample to a target point on the porous substrate along a sample axis; an imaging device and one or more lenses, positioned so that the imaging device and the lens each has a focus axis that is offset from the sample axis, and have a viewing focal point that is substantially the same as the target point; a light source that is offset from the delivery device to illuminate the surface target; and a processor comprising a data acquisition and control system that coordinates timing and automation of the delivery and imaging devices, and determines one or more characteristics of the porous substrate.
    Type: Grant

  • Patent number: 8643849
    Abstract: A measurement system comprising a light source unit, a projection unit and an optics unit is disclosed. The light source unit is configured to generate a plurality of modulated phase shifted light beams. The projection unit is configured to reflect the modulated phase shifted light beams onto an object surface. The optics unit is configured to capture the modulated phase shifted light beams from the object surface. The measurement system further comprises a photodetector and a processor. The photodetector is configured to receive the modulated phase shifted light beams from the optics unit to generate electrical signals. The processor is configured to retrieve position information of the object surface based on the electrical signals from the photodetector. A measurement method is also presented.

  • Publication number: 20060115817
    Abstract: The present invention relates to methods for diagnosing cancer in a subject The method involves obtaining a biological sample from a subject and measuring SPAN-Xb expression level in the biological sample. The SPAN-Xb expression level in the biological sample is compared to the SPAN-Xb expression level in a control sample from a subject devoid of cancer, where a greater SPAN-Xb expression level in the biological sample compared to the SPAN-Xb expression level in the control sample is indicative of the subject having cancer. Methods for monitoring progression/regression of cancer in a subject are also disclosed. The present invention also relates to methods of treating a subject with cancer. The method involves administering to the subject a therapeutically effective amount of an agent capable of eliciting an immunological response against SPAN-Xb protein or specifically recognizing a SPAN-Xb protein, under conditions effective to-treat a cancer characterized by cells expressing SPAN-Xb.
