The problem of searching for a low cost path from a source location to a target location through a traversable region partitioned into a plurality of tiles is solved using source and target cost functions. Each tile in the traversable region is defined by boundary segments. The source cost function provides a cost for traversing from the source location to the boundary segment in question. The target cost function provides a cost for traversing from the boundary segment in question to the target location. The target cost function is estimated, and the source cost function is calculated. A path cost function is determined by adding the source and target cost functions. If the target location is a tile, then the target cost may be estimated using a convex hull of the target tile and the boundary segment in question. To facilitate the cost function calculations, multiple forms of cost function propagation between segments are disclosed.

A method for dynamic personal identification number (PIN) management includes selecting a PIN comprising at least one picture category ID, determining a correspondence between at least one entry token and the at least one picture category ID and creating a picture category ID list in response to an access request. The picture category ID list includes the at least one picture category ID. The method also includes providing the picture category ID list for displaying a composite image including pictures based on the picture category ID list, receiving an entry token list in response to the providing and granting access to the service based upon whether at least one entry token in the entry token list corresponds to the at least one picture category ID. According to one aspect, the method also includes providing instructions to the user regarding which pictures are based on the PIN.

A clock interpolation circuit for setting and controlling a phase of an output clock that is derived from an interpolation of multiple input clocks. Interpolation is performed by capacitively weighting the multiple clocks. A select and control circuit provides the ability to select different capacitance values to control the weighting. An optional buffer stage is also provided to sharpen the edge transitions of the interpolated clock.

A telematics system is provided. The system includes a telematics client framework having an interface to client applications and being integrated with a client communications framework. The client communications framework has a client stream manager, a client data pump, a client policy manager, and a client channel monitor. The channel monitor detects availability of channels for communication with a telematics server framework. The telematics server framework includes an interface to server applications and is integrated with a server communications framework. The client channel monitor is configured to communicate availability of channels to connection objects of the client data pump. Switching between channels is triggered based on information obtained from the client policy manager.

The invention is directed to a method and apparatus for simulating a digital logic circuit simulator. In particular, a block object, representing a component of the digital logic circuit, is instantiated. An event object having a queue is also instantiated. The queue holds an ordered list of destinations, which are representative of the block objects that the event object initiates an action with. When the event object interacts with the block object, this initiates behavior in the block object indicative of behavior of the component in the digital system. The digital logic circuit simulator components, namely the block object and the event object, can be instantiated in a run-time object oriented language, such as the JAVAnull language promulgated by Sun Microsystems. The block object can initiate a dynamic addition to the destination queue. Additionally the destination can be another event object. When the destination is another event object, another event object is initiated. The new event object may be dynamically created within the instructions of adding to the destination queue, and may based upon test for the existence of a particular condition. The event object can alter a condition of the block object, and vice versa. As such, a system and method for simulating event behavior in a complex digital system is envisioned. Other objects, advantages and novel features of the present invention will be apparent to those skilled in the art from the following detailed description of the invention, the appended claims, and in conjunction with the accompanying drawings.

A method for obtaining a service on a data communications network, the method includes enrolling with an authority and using the enrollment results to obtain a service from a service provider. The enrolling creates enrollment results that include user data. The service provider is capable of communicating with the authority to verify the enrollment results
摘要:
In a distributed computing system, a first process may register interest in an event occurring in another address space or physical machine in such a way as to allow the subsequent notification of the event's occurrence to contain an object that includes methods that are to be run on receipt of the notification. When the notification is received, either by the first process or by some other entity designated by the first process to be the final point of notification, the methods may be executed as specified by the first process.
