A payment card comprises an internal dynamic card verification value (CVV) generator and a user display for card-not-present transactions. Card-present transactions with merchant card readers are enabled by a dynamic magnetic array internally associated with the card's magnetic stripe. The user display and a timer are triggered by the suer when the user needs to see the card verification value and / or begin a new transaction. A new card verification value is provided for each new transaction according to a cryptographic process, but the timer limits how soon a next new card verification value can be generated.

A virtualization infrastructure that allows multiple guest partitions to run within a host hardware partition. The host system is divided into distinct logical or virtual partitions and special infrastructure partitions are implemented to control resource management and to control physical I / O device drivers that are, in turn, used by operating systems in other distinct logical or virtual guest partitions. Host hardware resource management runs as a tracking application in a resource management “ultravisor” partition, while host resource management decisions are performed in a higher level command partition based on policies maintained in a separate operations partition. The conventional hypervisor is reduced to a context switching and containment element (monitor) for the respective partitions, while the system resource management functionality is implemented in the ultravisor partition. The ultravisor partition maintains the master in-memory database of the hardware resource allocations and serves a command channel to accept transactional requests for assignment of resources to partitions. It also provides individual read-only views of individual partitions to the associated partition monitors. Host hardware I / O management is implemented in special redundant I / O partitions. A scalable partition memory mapping system is implemented in the ultravisor partition so that the virtualized system is scalable to a virtually unlimited number of pages. A log (210) based allocation allows the virtual partition memory sizes to grow over multiple generations without increasing the overhead of managing the memory allocations. Each page of memory is assigned to one partition descriptor in the page hierarchy and is managed by the ultravisor partition.

Methods and systems are provided for assigning task-oriented roles to persons in an organization. In accordance with one aspect, such methods and systems may perform a process including providing a set of tasks that can be performed in an organization and defining a set of roles for persons in the organization.

In one aspect, the role assignment process is performed in a cascaded manner along hierarchical levels of the organization until roles at a lowest level of the organization are assigned to one or more persons. Further, the role assignment process allows business users to continue to assign the defined set of roles in the cascaded manner by only providing user names.

A radio link management system for a home or office substantially (i) an ad hoc network of agents wirelessly communicating among themselves, while (iii) clients wirelessly communicate with proximate agents. Control of the network may be centralized as network controller integrated with an agent, or may be distributed upon the network of agents. Some agent or agents, which may include an agent that is also the network controller, typically serves as a gateway device which connects to a worldwide communications network external to the home or office, normally by fiber or by wire.Each agent is most commonly a small radio transceiver plus logic and power supply that mounts upon a wall and plugs directly into an AC power socket. Agents wirelessly communicate among themselves and with the controller-which may be centralized or distributed-in a bandwidth-efficient mode since prime power is not an issue. Each client, which is most commonly a battery-powered user device, wirelessly radio communicates with one or more proximately-located agents. Consistent with overall demand for the radio resource, parameters for radio communication are allocated ad hoc in a manner which is (a) client-dependent, and which (b) uses the least power from the battery-powered client. The agents establish an ad-hoc network among themselves, with routing among and between the agents being both multi-hop and "minimum hop" to conserve bandwidth. Accordingly both power and bandwidth are conserved, each as and where required and desired.
