  • Patent number: 6959449
    Abstract: A system and method for simultaneously accessing video data and Internet page data includes a format manager that inserts a video tag into page data to concurrently display a positionable video window and the page data upon the screen of a display device. The format manager reformats the displayed page data to avoid the video window when shown on the display device. The format manager also maintains the video window in a stationary position when a system user scrolls the page data in relation to the video window.

  • Patent number: 6957217
    Abstract: A system and method for selectively providing information to a user device includes an event server that provides restricted access to various types of event content information and services related to a particular event. A wireless portable user device may provide an access code to the event server at a particular event location through a wireless base station that is coupled to a local area network. A system user may thereby utilize the user device to access the event server for downloading appropriate event content information and related services until the foregoing access code expires.

  • Patent number: 6952826
    Abstract: A method for implementing a multi-level system model for deterministically handling selected data comprises a picokernel module that invokes an isochronous scheduler to select, schedule, and execute active isochronous processes on an electronic device in response to a cycle start signal from an isochronous clock. The active isochronous processes may selectively set plesiochronous flags to thereby designate corresponding plesiochronous processes as active plesiochronous processes. Once all active isochronous processes have been executed in a given isochronous cycle, then the picokernel may invoke a plesiochronous scheduler to select, schedule, and execute any active plesiochronous processes on the electronic device.

  • Patent number: 6943909
    Abstract: A system and method for efficient transfer of image data to a service provider comprises a digital image source, an image pump, and a communication path to the service provider. The digital image source may be connected to the image pump using any appropriate communication configuration. Digital image data from the digital image source is transferred to the image pump, which may format the digital image data to conform to requirements of the particular service provider. The image pump may also attach customer account information and user service selections to the digital image data. The image pump may then send the digital image data and any attached information to the service provider. The service provider responsively may perform the requested services and return a finished product to the user.

  • Patent number: 6934781
    Abstract: A system and method for effectively performing isochronous data transfers comprises a network device including an input/output (I/O) bus that is coupled to an input/output (I/O) node and an isochronous-capable network interface. The network interface and the I/O node may send requests to an arbiter for control of the I/O bus to perform a data transfer operation. In accordance with the present invention, an arbiter filter is interposed between the arbiter and both the network interface and the I/O node to filter respective requests for control of the I/O bus. The network interface advantageously provides an isochronous request to the arbiter filter to thereby de-assert conflicting requests so that the network interface may effectively perform a time-sensitive isochronous data transfer.

  • Patent number: 6928646
    Abstract: A system and method for efficiently performing scheduling operations in an electronic device comprises an allocation manager that initially evaluates a task scheduling request based upon certain request parameters. The request parameters may include a resource requirement and an execution interval. If the task scheduling request is granted, then the allocation manager adds the corresponding task to a prioritized task table. A scheduling manager may then reference the task table to efficiently identify the next task for scheduling and execution on the electronic device.

  • Patent number: 6912136
    Abstract: Self-oscillating, current controlled switching power supplies, used for example, as energy storage device charging circuits, and related methods are provided herein. In one implementation, a switching power supply comprises a power transformer having a primary and a secondary, a switching element that switches a voltage source to the primary, and a control circuit that controls the operation of the switching element in response to the measured primary current and secondary current. The switching element disconnects the voltage source from the primary when the primary current reaches a first threshold, causing the secondary current to conduct. The switching element switches back to the primary when the secondary current drops to second threshold. The switching power supply oscillates between charging and discharging the power transformer. In one embodiment, a high value energy storage capacitor is coupled to the secondary and is charged with the secondary current.

  • Patent number: 6884162
    Abstract: A system and method to support electronic gaming in an electronic network includes an event server that provides restricted access to various types of game services. One or more system users may utilize corresponding wireless portable user devices for connecting to the event server to thereby gain access to the foregoing game services as game participants. The system users may thereby utilize the user devices to access the event server for accessing appropriate gaming services and related information. In addition, a source system user may utilize a source user device to perform a transfer procedure for transferring ownership rights of an electronic certificate related to the electronic gaming to a target system user through a target user device. The foregoing transfer procedure may be conducted through the event server, or may occur directly from the source user device to the target user device.

  • Patent number: 6850886
    Abstract: The present invention comprises a system and method for speech verification using an efficient confidence measure, and includes a speech verifier which compares a confidence measure for a recognized word to a predetermined threshold value in order to determine whether the recognized word is valid, where a recognized word corresponds to a word model that produces a highest recognition score. In accordance with the present invention, the foregoing confidence measure may be calculated using the recognition score for the recognized word and a pseudo filler score that may be based upon selected average recognition scores from an N-best list of recognition candidates.
