Abstract: An originating email server is authenticated by a destination email server using a public key provided by the originating email server, thereby making it possible to detect an email with a forged origination address with no action required by a domain owner. A personal computer is authenticated using a reputation report associated with a unique number corresponding to the personal computer, enabling, in one embodiment, spam detection, and, in another embodiment, a decision that a valid user is requesting service registration at a website.

Abstract: A jaw movement mechanism for surgical tools has improved mechanical efficiency and other advantages. The jaw movement mechanism controls the orientation and position of a movable jaw relative to a fixed jaw through a range of movement of the movable jaw. The jaws maintain a parallel orientation throughout a portion of the range of movement of the movable jaw. The jaws maintain an angular relationship throughout a portion of the range of movement of the movable jaw.

Abstract: The portion of email traffic that cannot be definitively determined to be spam or definitively determined to be ham (non-spam) is processed by sending a bounceback email to the sender, requiring the sender to reply using a sub-address created by the bounceback generator. The type of bounceback email depends on whether the domain of the received email indicates that the sender is or is not likely to be a spammer. When the sender is not likely to be a spammer, the bounceback email includes a sub-address in computer readable form. When the sender is likely to be a spammer, the bounceback email includes a test that must be solved to yield the sub-address; preferably, the test is very difficult for a computer to solve but reasonably easy for a human to solve. When a reply email to the bounceback email (“reply bounceback”) is received, the presence of the sub-address indicates that the sender is not a spammer, so the reply bounceback is determined to be ham and delivered to the destination mailbox.

Abstract: A system and program product for enabling dormant computer hardware resources in a computer system having a set of dormant computer hardware resources. The method includes accepting a customer request to enable a set of dormant hardware resources, and providing computer readable instructions to a customer accessible console in communication with the computer system. The instructions are installable by the customer, and are capable of enabling dormant computer hardware resources upon installation. An order process establishes prerequisites, facilitates customer order placement, and provides rapid order fulfillment. Prerequisites include contract terms, information describing the computer system configuration, access to provider systems, and customer system setup. Ordering is facilitated through information management, configuration rules, and an interactive interface, presenting valid configuration options to the customer.

Abstract: A computer application program on a supplier computer system receives an order from a customer by way of a computer customer system for a customer selected product, the computer application program having a predetermined time period and negotiates billing information with said customer for the purchase of said ordered customer selected product, said negotiated billing information for billing said customer for the purchase of said ordered customer selected product. If the customer takes delivery of said customer selected product within said predetermined time period, the computer application program billing said customer for said delivered customer selected product, however if the customer does not take delivery of said customer selected product within said predetermined time period, the computer application program cancelling said order and cancelling said billing according to said billing information based on expiration of said predetermined time period.
