102 results about "Inner envelope" patented technology

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.

The invention belongs to the technical field of metal plastic processing, and aims at providing a superplastic forming/diffusion bonding forming method for a heat-resistant titanium alloy envelope with high material utilization ratio, high dimension control precision and high product performance.

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.
