  • System and method for optical coherence tomography a-scan decurving
    Patent number: 11974807
    Abstract: An OCT system for measuring a retina as part of an eye health monitoring and diagnosis system. The OCT system includes an OCT interferometer, where the interferometer comprises a light source or measurement beam and a scanner for moving the beam on the retina of a patient's eye, and a processor configured to execute instructions to cause the scanner to move the measurement beam on the retina in a scan pattern. Measurement data may be processed using a decurving process to enhance the resolution of the ILM layer and provide improved determinations of retinal thickness.

  • Tip-headed needle
    Patent number: 6973807
    Abstract: A stitch needle (10) is provided with a tip (29) which is shaped as a center punch and has no recognizable rounding at its terminus (31). The tip (29) is preferably arranged at mid height of the hook-shaped aperture (36) which is structured for capturing the yarn (13).
