Abstract: A method for generating a looping motion space for real-time character animation may include determining a plurality of motion clips to include in the looping motion space and determining a number of motion cycles performed by a character object depicted in each of the plurality of motion clips. A plurality of looping motion clips may be synthesized from the motion clips, where each of the looping motion clips depicts the character object performing an equal number of motion cycles. Additionally, a starting frame of each of the plurality of looping motion clips may be synchronized so that the motion cycles in each of the plurality of looping motion clips are in phase with one another. By rendering an animation sequence using multiple passes through the looping motion space, an animation of the character object performing the motion cycles may be extended for arbitrary length of time.

Abstract: A method for generating real-time goal space steering for data-driven character animation is disclosed. A goal space table of sparse samplings of possible future locations is computed, indexed by the starting blend value and frame. A steer space is computed as a function of the current blend value and frame, interpolated from the nearest indices of the table lookup in the goal space. The steer space is then transformed to local coordinates of a character's position at the current frame. The steer space samples closest to a line connecting the character's position with the goal location may be selected. The blending values of the two selected steer space samples are interpolated to compute the new blending value to render subsequent frames of an animation sequence.

Abstract: The systems and methods disclosed herein employ a combination of digital three-dimensional modeling and rapid fabrication technologies to provide pre-indexed, pre-registered, and/or precut components for articulated dental models. Dental articulators and components of dental models as described herein use a positioning key to encode positional information for components of the dental model, and/or a reference grid on mounting surfaces to enforce local accuracy of fabricated parts against a fixed reference array.

Abstract: A method and device are disclosed for treating congestive heart disease. The material of the device is secured to the heart proximate the septal wall. The material covering the ventricles may or may not have the same tension and or compliance. The device can be constructed as a unitary “jacket” that is slipped over the apex of the heart. Alternately, the device implanted as one, two or more separate components. In one embodiment, the material covers both the left and right ventricles. In another embodiment, the material covers only one ventricle. The device may include at least one adjustment mechanism configured to adjust the tension of the material.

Abstract: A jacket of biological compatible material has an internal volume dimensioned for an apex of the heart to be inserted into the volume and for the jacket to be slipped over the heart. The jacket has a longitudinal dimension between upper and lower ends sufficient for the jacket to surround a lower portion of the heart with the jacket surrounding a valvular annulus of the heart and further surrounding the lower portion to cover at least the ventricular lower extremities of the heart. The jacket is adapted to be secured to the heart with the jacket surrounding at least the valvular annulus and the ventricular lower extremities. The jacket is adjustable on the heart to snugly conform to an external geometry of the heart and assume a maximum adjusted volume for the jacket to constrain circumferential expansion of the heart beyond the maximum adjusted volume during diastole and to permit unimpeded contraction of the heart during systole.

Abstract: In general, the present invention contemplates an implantable device for treating excessive bleeding in a body cavity. The device comprises a biocompatible material, for example polyethylene teraphathalate (PET), which is deliverable into the body cavity. The biocompatible material contains an attribute(s) that promotes tissue reaction or growth that results in a tissue response and/or adhesion formation within the body cavity to reduce or stop the excessive bleeding.

Abstract: A highly compliant and elastic cardiac support device is provided. The device is constructed from a biocompatible material is applied to an external surface of a heart. The device can be used to resist dilatation of the heart, to provide acute wall support, or to enhance reduction in the size of the heart using stored potential energy, without interfering with systolic contraction.

Abstract: A device for treating cardiac disease of a heart having an upper portion and a lower portion divided by an A-V groove, the device including a jacket adapted to be secured to the heart, and a non-adherent material in association with the jacket. The jacket is fabricated from a flexible material defining a volume between an upper and a lower end, the jacket being adapted to be adjusted on the heart to snugly conform to an external geometry of the heart and assume a maximum adjusted volume for the jacket to constrain expansion of the heart beyond the maximum adjusted volume during diastole and permit substantially unimpeded contraction of the heart during systole. As a result of the flexible material, the jacket allows unimpeded diastolic filling of the heart.
