Patent number: 6467778Abstract: An ice skate comprising a blade and a blade holder. The blade holder providing decreasing, non rigid, and/or no lateral support in a rearward region of the blade so that it may facilitate increased or freer flexibility of the blade and improved maneuverability. The blade is rigidly laterally supported at a front end section of the blade holder and preferably also at a back end section of the blade holder so that it may facilitate efficient transfer of force between the skater and the blade. One or more non-rigid support members may be employed to control, absorb and/or cushion the flexing of the blade. The ice skate may be tuned to reflect the desired performance requirements of the individual skater and/or use.Type: GrantFiled: September 16, 1998Date of Patent: October 22, 2002Assignee: Jas D.

Patent number: 6466584Abstract: A system and method for performing a digital subscriber line (DSL) transmission over an AC-link bus directly connecting a modem codec to a codec controller. The codec and codec controller connected to the AC-link bus are configured for a particular industry-defined AC-link bus protocol defining a data packet having multiple time-division multiplexed (TDM) data slots, where the present invention redefines the protocol of the AC-link bus in order to allow a high bandwidth DSL transmission to be performed using the data packets transmitted over the AC-link bus. The present invention redefines the AC-link bus protocol to provide at least one additional TDM data slot in the data packet for handling DSL modem transmission data streams. The reconfigured data packet provides additional bandwidth capabilities which allow high-bandwidth DSL modem transmissions to be sent in the data packets transmitted over the AC-link bus, which where not previously achievable using the industry-defined AC-link protocol.Type: GrantFiled: September 30, 1998Date of Patent: October 15, 2002Assignee: Conexant Systems, Inc.Inventors: Conrad A.

Patent number: 6461364Abstract: Apparatus and methods are provided for use in sealing a vascular puncture site. The invention comprises an introducer sheath with an integrated closure component. The closure component includes a fastener and an advanceable, deformable clip having a delivery configuration in which opposing sides do not contact one another, and a deployed configuration, in which the fastener causes opposing sides of the deformable clip to close towards one another. The clip is advanced along the sheath until it pierces opposing sides of a vessel wall at a puncture site. The clip is then deformed with the fastener to draw opposing sides of the puncture together, and the sheath is withdrawn to seal the wound. The clip and fastener preferably are bioabsorbable.Type: GrantFiled: April 11, 2000Date of Patent: October 8, 2002Assignee: Integrated Vascular Systems, Inc.Inventors: Richard S. Ginn, William N.

Patent number: 6463332Abstract: The invention modifies the pericardium to treat patients suffering from or at risk of heart failure of the type wherein constraining forces of the pericardium around the heart are inadequate to prevent remodeling of the heart. The pericardium is enhanced by restoring, increasing, or improving its ability to restrain the heart and prevent dilation of the chambers of the heart. Methods and apparatus are provided for stiffening, strengthening, tightening, reshaping, and/or shrinking the pericardium to enhance the restraining and supporting capability of the pericardium around the heart. Specific embodiments enhance the pericardium by heating the pericardial tissue using radiofrequency energy and the like, treating the pericardium with a chemical such as glutaraldehyde, plicating the pericardium, or some combination of the above.Type: GrantFiled: September 14, 2000Date of Patent: October 8, 2002Assignee: Core Medical, Inc.Inventor: William N.

Patent number: 6462769Abstract: An image correction method of compensating for point of view image distortion in pictures includes the steps of obtaining an image at a first position within a predetermined frame, wherein at the first position the image is distorted due to point of view image distortion. The image obtained comprises an array of pixels. The distorted image is transformed into a compensated image by re-mapping the array of pixels of the distorted image using a predetermined transforming function that stretches the distorted image to fill the entire frame. The transformation function depends on the geometric orientation of the camera, projector, projecting surface, and viewer. The compensated image is projected at a second position different from the first position, wherein the projection of the compensated image substantially reduces point of view image distortion at the first position. This method can be employed for stationary and moving point of views.Type: GrantFiled: October 16, 2000Date of Patent: October 8, 2002Assignee: Universal City Studios, Inc.Inventors: Scott Trowbridge, Thierry J. Coup

Patent number: 6459800Abstract: A receiver suspension for isolating a hearing device receiver within a hearing device comprises a housing that defines a chamber. The housing is adapted to be inserted into a hearing device shell. The receiver suspension also comprises a cover that is adapted to engage with a proximal end of the housing. An isolation membrane at least partially surrounds the hearing device receiver such that, upon inserting the hearing device receiver into the housing, the isolation membrane suspends the receiver within the housing chamber, thus preventing the receiver from contacting the inside surface of the housing. Preferably, the isolation membrane is formed from a stretched polymer material such as polyurethane or silicone and forms a series of pleats when engaged with the receiver. Alternately, the receiver suspension includes an isolation spring having two grasping members interconnected with a flexure member.Type: GrantFiled: July 11, 2000Date of Patent: October 1, 2002Assignee: Sonic Innovations, Inc.Inventor: Owen D.
