Prosthetic devices as described for use in the treatment of aortic stenosis in the aortic valve of a patient's heart, the prosthetic device having a compressed state for transarterial delivery and being expandable to an expanded state for implantation. The prosthetic device includes an expandable metal base (10) constructed so as to be implantable in the expanded state of the prosthetic device in the aortic annulus of the aortic valve; and an inner envelope lining (11) tune inner surface of the metal base (10). The inner envelope, in the expanded state of the prosthetic device, extends into the aorta and is of a diverging conical configuration, in which its diameter gradually increases from its proximal end within the aortic annulus to its distal end extending into the aorta, such as to produce, during systole, a non-turbulent blood flow into the aorta with pressure recovery at the distal end of the inner envelope. Preferably, the distal end includes a prosthetic valve which is also concurrently implanted, but such a prosthetic valve may be implanted separately in the aorta Also described are preferred methods of implanting such prosthetic devices.

A method, system, and computer readable medium containing programming for handling fully authenticated transmission of video or other data (content) from a provider to a recipient device via an intermediary device. An inner envelope containing the content and/or security features is prepared and digitally signed using a private cryptographic key. The signed inner envelope is then included in a second, outer envelope which may also include some or all of the content. The outer envelope is also digitally signed, thereby forming a data package which may be sent from the provider to the intermediary device. If the signature of the outer envelope is authenticated at the intermediary device, then the inner envelope is sent to the recipient device which then uses the inner signature to verify its authenticity. Authenticated content may then be presented or otherwise used at the recipient device.

A multi-piece solid golf ball has a core, an envelope layer encasing the core, an intermediate layer encasing the envelope layer, and a cover which encases the intermediate layer and has formed on a surface thereof a plurality of dimples. The envelope layer is formed of an inner envelope layer, an intermediate envelope layer and an outer envelope layer. The inner, intermediate and outer envelope layers, the intermediate layer and the cover are each formed primarily of a resin material which may be of the same or different types, and the core is formed primarily of a rubber material. The cover has a material hardness which is the same as or lower than the core center hardness. One of the inner layers has a material hardness which is higher than either or both of the cover material hardness and the average core hardness (defined as the arithmetic mean of the core surface hardness and the core center hardness). The golf ball, even when used by those golfers among professionals and skilled amateurs who, on striking a ball with a driver, tend to generate shots having a rather low spin rate and a low launch angle, has an excellent flight performance and also excellent controllability in the short game that are acceptable to such users. In addition, it has a good feel on impact and an excellent scuff resistance.

A multi-piece solid golf ball has a core, an envelope layer encasing the core, an intermediate layer encasing the envelope layer, and an outer layer which encases the envelope layer and has formed on a surface thereof a plurality of dimples. The core is made of an elastomer. The envelope layer is formed of an inner envelope layer and an outer envelope layer, and the intermediate layer is formed of an inner intermediate layer and an outer intermediate layer. Letting the average hardness of the core be expressed by the following formula:

average core hardness (Shore D)=[core surface hardness (Shore D)+core center hardness (Shore D)]/2,

the outer layer has a hardness (Shore D) which is higher than the average core hardness and each of the envelope layers and the intermediate layers is softer than the outer layer.

The invention provides a multi-piece solid golf ball in which importance is placed on achieving an excellent flight when played by ordinary amateur golfers who do not have a very high head speed, and on having a good, soft feel on impact.

A method is for detecting a possible collision of at least two objects moving with respect to each other by simulating the intended relative motion of the two objects. At least one of the objects is assigned an envelope surrounding the object, the path line represents the relative motion of the objects is covered in steps of a defined step size, and the occurrence of an overlap of the objects is detected for ascertaining a possible collision of the objects. For at least one object, the outer contour of the corresponding envelope is used as a datum for detecting an overlap. At least one object is assigned an inner and an outer envelope, of which the inner envelope surrounds the object and the outer envelope surrounds the inner envelope.
