Abstract:

Apparatus, system, and method for delivering data to multiple memory clients are described. In one embodiment, a graphics processing apparatus includes an output pipeline including a set of memory clients. The graphics processing apparatus also includes a memory controller connected to the output pipeline. The memory controller is configured to retrieve data requested by respective ones of the set of memory clients from a memory. The graphics processing apparatus further includes a buffering module connected between the memory controller and the output pipeline. The buffering module includes a unitary buffer and a buffer controller connected to the unitary buffer. The buffer controller is configured to coordinate storage of the data in the unitary buffer, and the buffer controller is configured to coordinate delivery of the data from the unitary buffer to respective ones of the set of memory clients.

Abstract:

A graphics processing apparatus includes an output pipeline including a set of memory clients. The graphics processing apparatus also includes a memory controller connected to the output pipeline. The memory controller is configured to retrieve data requested by respective ones of the memory clients from a memory. The graphics processing apparatus further includes a buffering module connected between the memory controller and the output pipeline. The buffering module includes a buffer including a buffering space shared by the memory clients. The buffering module also includes a buffer controller connected to the buffer. The buffer controller is configured to: (1) dynamically assign portions of the buffering space to respective ones of the memory clients; (2) coordinate storage of the data in the assigned portions; and (3) coordinate delivery of the data from the assigned portions to respective ones of the memory clients.

International Classification:

G06Q 99/00

US Classification:

705 78, 705 64, 705 72, 705 44

Abstract:

A payment authentication service authenticates the identity of a payer during online transactions. The authentication service of the present invention allows a card issuer to verify a cardholder's identity using a variety of authentication methods, such as the use of passwords. Also, the only system participant requiring a certificate is the issuing financial institution. One embodiment of the invention for authenticating the identity of a cardholder during an online transaction involves querying an access control server to determine if a cardholder is enrolled in the payment authentication service, requests a password from the cardholder, verifies the password, and notifies a merchant whether the cardholder's authenticity has been verified. In another aspect of the invention, a chip card and the authentication service independently generate cryptograms that must match in order for the service to verify that the correct chip card is being used by the cardholder.

International Classification:

B62J 7/00

US Classification:

224413, 224463, 224583, 224585

Abstract:

A baggage system including a first bag supported by a rigid frame may be secured by anchoring straps to a luggage rack or a passenger's back rest of a motorcycle with wrap-around straps. In addition, fasteners are provided on a surface of the first bag to provide corresponding attaching points to fasteners on a second bag. As a result, two-bag system is formed and secured around the passenger seat rest of a motorcycle. Each of the first and the second bag provides attachment structures for attaching front pouches, side pouches and cold-drink pouches. The cold-drink pouch is insulated for cold drinks.
