    摘要： A surgical access port comprises a valve or instrument seal that separates the instrument contact function from the instrument conforming function. Embodiments of the instrument seal comprise in instrument contact element that extends through an opening in a compression element, thereby defining an instrument orifice that seals with an instrument extending therethrough. Embodiments of the instrument contact element comprise a non-distensible membrane or film, for example, as a tube or cylinder. Some embodiments of the instrument contact element have an hourglass configuration with a first end proximal of the opening of the compression element and a second end distal of the opening of the compression element. Other embodiments of the instrument contact element “wrap around” the opening in the compression element, with the first end and the second end secured to the same side of the opening, for example, proximal of the opening. Embodiments of the compression element comprise an elastomeric seal, for example, a septum seal and/or a gel seal.

    摘要： A balloon trocar includes a cannula assembly including a cannula and an outer sleeve fitting over the cannula. The distal end of the outer sleeve is proximal to the distal end of the cannula. A balloon is coupled to a distal portion of the sleeve and a distal portion of the cannula. The outer surface of the cannula includes a plurality of longitudinal channels for transmitting gas or fluid to the balloon. A bolster having a gel pad at its distal portion is slidably mounted to the cannula assembly and may be locked in a desired position. In use, the trocar is inserted into an incision through a body wall and into a body cavity. The balloon is inflated and the cannula assembly pulled proximally against the incision while the bolster is slid distally to the body wall and locked in place to seal the incision with the compressed balloon.

    摘要： A method of determining a partition into distinct regions of a set of coefficients representative of at least a part of an image in order to insert a watermark comprises the following steps: generation (E501) of a centred pseudo-random sequence (w) equal in size to the cardinal number (N) of the said set of coefficients, formed from centred pseudo-random sub-sequences; modulation (E502) of the said set of coefficients by the said centred pseudo-random sequence (w) in order to insert the same information bit on the said set of coefficients; and checking (E504–E508), over each region, of a criterion of detectability of the information bit inserted by modulation. Use especially for determining an adaptative partition as a function of a criterion of detectability of an information bit inserted on each region.

    摘要： The invention concerns a method of determining a segmentation into distinct regions of a set of coefficients representing at least part of an image (IM) in order to insert a set of watermarking signals with a predetermined cardinal, characterized in that it includes the steps of: generating (E2) a set of acceptable segmentations, calculating (E3), for each acceptable segmentation, a probability of error on the detection of the watermarking signals inserted in said each acceptable segmentation, and selecting (E3) a segmentation in the set of acceptable segmentations, by minimizing, on all the acceptable segmentations, the probability of error subject to a constraint on the cardinal of the regions of the selected segmentation, with respect to the cardinal (C) of said set of watermarking signals.

    摘要： A method of inserting additional information, such as a digital signature, in a digital image comprises the following steps: detecting (E10) the points of interest in said image (I); selecting (E11) a subset of points of interest adapted to define a geometric reference frame in said image (I); calculating (E12), for the geometric reference frame, reference information necessary for determining the geometric transformation applied to the image for a class of predetermined geometric transformations; coding (E13) said reference information in a reference key (Kr); and inserting (E16-E19) the additional information in said digital image (I). Use notably for geometrically re-fixing the image before extracting the signature.
