Abstract: A surgical tissue bag (301) for percutaneously debulking large volumes of tissue contained within the bag (301). The tissue bag (301) comprises two layers of material, an inner layer of a puncture-resistant material and an outer layer of moisture-proof material for containing cells and fluid therein. The bag (301) material is foldable and flexible for insertion through an access sheath (302) into the surgical site and for forming a gas-tight seal when extended through the access sheath (302) or puncture site. A drawstring (310) is attached to the open end of the bag (301) to close the bag (301) when the tissue is contained therein and pulled through the puncture site in the outer surface of the skin (304). After the closed open end of the bag (301) is pulled through the puncture site, the closed end is fanned out against the outer layer of the skin, and a morcellator is inserted into the bag for debulking the large volume of tissue. The open end of the bag is continully fanned out to maintain a compact and tight containment of the tissue and fluid remaining in the bag. The morcellation process is continued until the entire volume of tissue is removed at which time the remaining portion of the bag (301) is completely removed from the surgical site area.

Abstract: New biodegradable functional polyesters and polycarbonates can be produced by copolymerization of cyclic anhydrides and carbon with the glycidyl ethers of protected alditols, N-glycidyl pyrrolidone and their mixtures with alkylene oxides in the presence of suitable polymerization catalysts. Such polyesters and polycarbonates are constituted by monomeric residues containing one or more isopropylidene group in the side chain. They can be converted, by partial or complete removal of side chain isopropylidene groups, to the corresponding polymers having two or more free hydroxyl units per structural unit derived from the alditol glycidyl ether. The resulting polyhydroxylated polyesters and polycarbonates are well suited for the production of thermoplastics and thermosets and for the formulation of biodegradable systems to be used in pharmaceutics and biomedicine.

Abstract: A method of modifying a time-varying image sequence in which a parametric velocity vector field that characterizes changes in successive images of the image sequence is estimated. The estimating includes combining optical flow constraints, directional smoothness constraints and regularization constraints in a functional of the estimate of the parametric velocity vector field such that the weighting coefficients of the functional are functions of the parametric velocity vector field to be estimated. A system of nonlinear equations that arise from the optimality criterion of the functional are then solved. Once the system of nonlinear equations is solved, the estimate of the parametric velocity vector field is applied to modify at least one image in the image sequence.

Abstract: A system and method for creating three-dimensional or depth image font text characters using graphic three-dimensional object creation techniques and processors. The text characters can be represented as set descriptions of the characters. The text characters can also be represented as a three-dimensional geometric model including polygons constructed from vertices defined by three-dimensional coordinates. The representations are stored in a font storage and when a user specifies the text characters to be used in a depth image along with the font to be used for the text characters, the geometric representations of the characters are retrieved. If stored as a set, the set is converted into a geometric plot. Appropriate scaling and surface texturing operations are performed as designated by the user to create three-dimensional text character graphic objects. These text character graphic objects are transferred to a graphics processor to be manipulated as desired by the use and used to produce an image that can be further processed.

Abstract: Difference flag logic suitable for use in a FIFO memory is modified to quickly generate FIFO flag status without the use of subtractor circuitry. Bit comparators, which determine if a first bit is less than, equal to, or greater than a second bit, of a magnitude comparator are divided into groups which generate compare output signals in parallel to one another, thereby reducing total magnitude comparator delay and resulting in faster operation. These compare output signals are the inputs of a control element which determines which compare output signal is allowed to pass through as the final compare output signal. The subtractor function is replaced by offsetting the read count from the write count by a value equal to the desired FIFO flag value. In addition, control of selected bits, such as the most significant bits (MSBs), of the numbers is included and may be used as necessary to avoid a wrap-around condition.

Abstract: An apparatus for generating an image to be displayed on a display screen from data defining a model including a plurality of opaque and translucent features. The image is intended to represent a view of the model from a predetermined eyepoint and is made up from an array of screen space pixels to be displayed by a raster scanning process. Each pixel is of uniform colour and intensity, and the pixels together define an image area. The image area is divided into an array of sub-areas each of which covers at least one pixel. For each feature in the model that is potentially visible from the eyepoint, a test is conducted to determine which of the sub-areas is at least partially covered by that feature. A list of feature identifiers is produced in respect of each sub-area, the list for any one sub-area identifying features which at least partially cover that sub-area. The position in screen space of at least one sampling point within each sub-area is determined. For each sub-area in turn, and for each sampling point a test is conducted to determine which of the features in that sub-area's list cover that sampling point. For each feature which covers a sampling point, a function of the distance from the eyepoint to that feature at the sampling point is determined. Feature describing data is stored for each sampling point within a sub-area, the stored data being indicative of at least the distance of the opaque feature which covers the sampling point and is nearest to the eyepoint and the distance and translucency of at least one nearer translucent feature which covers the sampling point. An output is produced for each sampling point within a sub-area, the sampling point output corresponding to the combined effects of the features identified by the stored data. An output for each pixel within a sub-area is produced, the pixel output corresponding to the combined effects of the sampling point outputs for all sampling points which contribute to that pixel, and the pixel outputs are displayed.
