Abstract:
Methods and apparatus for transferring a communication and computer session between devices. A user launches a communication session on a first device, such as a personal computer. The user may then selectively transfer the communication session to another device, such as a wireless device, through activation of a triggering signal. In response, the context of the communication session is determined as it is being performed on the first device, including a type of the communication session. The communication session is then transferred to the second device by launching a new communication session on the second device and transferring the context of the communication session corresponding to the first device to the new communication session on the second device. The communications session is continued via use of the first device as a proxy for the second device.
Abstract:
A method and system for monitoring wireless data service performance of wireless service providers. Data messages are sent from a plurality of remote and/or local monitoring probes to other monitoring probes. In general, the remote monitoring probes will be distributed throughout a service area(s) from the service provider and include both fixed probes and mobile probes, wherein each probe will include one or more wireless devices, including cellular phones, PSC phones, PDA devices, Blackberry devices, and the like. Various performance data are then measured, including message deliver latency and network accessibility. This data is then sent from the remote monitoring probes to one or more central monitoring stations, where it is stored and aggregated to generate performance reports and alerts, which are delivered to the service providers or may be accessed through a web user interface. In addition, wireless Internet access service performance is monitored using the remote and local monitoring probes, wherein various access functions are performed using WAP-enabled wireless devices.
Abstract:
A method and system for transferring a computer session between devices, such as a land-line device to a wireless device. A user launches a computer session on a first device, such as a personal computer. The user may then selectively transfer the computer session to another device, such as a wireless device, through activation of a triggering signal or other transfer request means. In response, the context of the computer session is determined as it is being performed on the first device, and corresponding context data is transferred to the second device. An applicable application on the second device is opened and loaded with applicable context data to continue the session. Several session transfer mechanisms, including use of an online service, proxy mechanisms, and peer-to-peer communication links, are disclosed.
Abstract:
An enhanced postal data modeling framework, in which postal data which describes characteristics of a mail sortation process is accessed, and the postal data is mapped to production management data which describes characteristics of a model production management process in an initial state and which is capable of being processed by a production management application. The production management data is input for processing by the production management application to produce forecasted production management data which predicts characteristics of the model production management process in a subsequent state, the forecasted production management data is modeled to forecasted postal data which predicts characteristics of the mail sortation process, and at least a portion of the forecasted postal data is provided to a user.
Abstract:
This invention relates to a Start-Stop method for a heavy-duty hybrid vehicle that turns off the internal combustion engine when the vehicle stops or, optionally, when the vehicle travels downhill. The Stop-Start method automatically restarts the internal combustion engine when the vehicle starts accelerating or is no longer traveling downhill. The software instructions for the Stop-Start method reside within the programming of the hybrid vehicle control computer as a subset of the hybrid vehicle control strategy in hybrid-electric or hybrid-hydraulic heavy-duty vehicle. During the time the internal combustion engine is turned off the necessary vehicle accessories operate from the available power of the hybrid high power energy storage.
Abstract:
A start-stop or idle-stop method for a heavy-duty hybrid vehicle that turns off the fuel supply while maintaining the crankshaft rotation of the internal combustion engine when the vehicle stops or, optionally, when the vehicle travels downhill, travels in a noise sensitive location, travels in an exhaust emissions sensitive location, or operates in an emergency situation. The stop-start or idle-stop method automatically turns on the engine fuel supply to restart combustion when the vehicle starts accelerating, is no longer traveling downhill, is no longer traveling in a noise sensitive or exhaust sensitive location, is no longer in an emergency situation, or has dropped below the minimum energy storage restart level.
Abstract:
A client computer runs an operating system that executes additional applications by loading them using an application loader and executes device drivers for peripheral devices by loading the drivers using a device loader. The operating system restricts the functionality of the operating system, such as by making selected portions and functionality of the operating system unavailable to the user or by limiting the user's ability to add software applications or device drivers to the computer. Additionally, various techniques can be used to remove or reduce the functionality limitations of the computer

Abstract:
In a broadcast system in which computer data and other content are delivered from multiple content servers to multiple clients at least partly over a broadcast network, a transmission announcement system announces upcoming broadcast transmissions and instructs the clients on how to receive the broadcast transmissions. Announcement servers (which may or may not be the same as the content servers which serve the data for the broadcast transmissions) generate announcements containing information specifying how associated upcoming transmissions are to be delivered over the broadcast network. The announcement server makes the announcements available to the clients over the broadcast network or over a secondary link other than the broadcast network. As possible examples of the secondary link, the announcement servers might send the announcements to a multicast address over a public network, such as the Internet, or post the announcements at a publicly accessible site on a data network, such as a Web site on the Internet. The clients receive the announcements via the broadcast network or the secondary link. The clients filter the announcements according to predetermined criteria, keeping the announcements satisfying the criteria and discarding the rest. The client searches the announcements that are kept to extract information pertaining to retrieval of the broadcast transmission (e.g., a broadcast protocol, a broadcast locator, a transmission time, etc.). The client then tunes a broadcast receiver to the broadcast locator and launches a receiving application to receive the transmission according to the broadcast protocol.
Abstract:
A data delivery system facilitates transmission of data packets from a content server to multiple clients over a unidirectional network. A redundancy formatter resident at the server groups multiple data packets into a redundancy group and generates at least one redundancy packet containing redundancy information derived from the data packets in the redundancy group. The data packets and redundancy packet are sent over the unidirectional network to the client. In the event that a packet is lost, a packet rebuilder resident at each client reconstructs the missing data packet from the successfully transmitted data packets in the redundancy group and the redundancy packet for the redundancy group.
