Abstract: Apparatus and methods are described for calibrating an optical system that is used for measuring optical properties of a portion of a subjects body. During a calibration stage, a front surface of a calibration object (300) is illuminated, light reflected from a plurality of points on the calibration object (300) is detected, and intensities of the light reflected from the plurality of points on the calibration object (300) are measured. During a measurement stage, the portion of the subjects body is illuminated, and light reflected from the portion of the subjects body is detected. Measurements performed upon the light that was reflected from the portion of the subjects body are calibrated, using the measured intensities of the light reflected from the plurality of points on the calibration object (300).

Abstract: A contraceptive device is provided including an occluding component for deployment in a tubal lumen of a reproductive organ. The device includes an expandable frame reversibly expandable from a collapsed state to an expanded state and a barrier supported by the expandable frame. In the expanded state the barrier is disposed between the expandable frame and walls of the lumen to inhibit in-growth of cellular material into and onto the occluding component, and additionally the barrier is urged against walls of the tubal lumen to define at least two tube lumen sealing areas, disposed perpendicular to a longitudinal axis of the walls of the tube lumen such that (i) the expandable frame is disposed between the two tubal lumen sealing surface, and (ii) passage of reproductive cells through the expandable frame, and through the tube lumen is blocked, therefore, creating a the complete blockage for liquids from a first part of the tube to a second part of the tube, downstream the first part.

Abstract: An aspect of some embodiments of the current invention relates to a system for 3D viewing of a gem stone based on 3D image processing technology. Optionally, the views are not based on synthetic modeling of the stone (which may risk producing false images). For example, the system may be based on a standard 3D image processing an array of 2D images at different angles. Optionally, the device takes advantage of standard shapes of diamonds, for example at 16 equally spaced angles around the girdle of a round brilliant cut.
