摘要:
A power controller in a communication system adjusts the transmitted power level using adaptive prediction of channel fading for maintaining the power level for improved communications by using an adaptive nonlinear predictor that explicitly takes into account the propagation delay and channel fading where the transmitted power is determined on the basis of the measurement of the received power levels over the individual diversity branches for providing communication through a fading channel with effective performance equivalent to that of a channel without any signal fading.

A portable, digital electronic device (10) is disclosed which comprises a host unit (20), including a display (21), and a keyboard module (40) connected to the host unit (20) and including at least one group of keys (41, 42, 43). The keyboard module (40) is moveable between at least two allowable positions with respect to the host unit (20), wherein a first allowable position of the at least two allowable positions results in the keyboard module (40) substantially covering the display (21), and wherein a second allowable position of the at least two allowable positions results in the display (21) being at least partially exposed.

A method and system for adaptively prefetching objects from a network has been disclosed. The invention includes adaptively tuning a prefetch engine to prefetch a plurality of objects from within the network. Because the prefetch engine is adaptively tuned, the prefetch process is optimized, thereby reducing the number of idle cycles that would otherwise be required to retrieve objects from the network. The method and system includes monitoring at least one proxy server within the network, the at least one proxy server comprising a prefetch engine and adaptively tuning the prefetch engine to prefetch a plurality of objects from within the network.

A grid computing system is disclosed. The grid computing system includes one or more printer nodes representing distributed print resources, an information repository, and a grid distributed resource manager. Continuing, the information repository includes printer attributes associated with the printer nodes. Further, the grid distributed resource manager provides a virtual printer to a user based on the distributed print resources. Also, the grid distributed resource manager accepts and assigns print jobs submitted to the virtual printer by the user.

A method for handing off to a second server, in either a fixed or mobile streaming media system, a multiple description streaming session between a first server and either a fixed or mobile client. In one embodiment, the present invention recites selecting a second server to receive a handoff of a multiple description streaming media session between the first server and the client. In this embodiment, the multiple description streaming media session is comprised of a first multiple description bitstream and a second multiple description bitstream. The present embodiment further recites receiving at the second server, the second multiple description bitstream for streaming to the client. This embodiment further recites sending the second multiple description bitstream from the second server to the client.

A handheld computing device (10) having voice input and voice output includes a handheld unit (20) having a processor (11) and a display (18) communicating with the processor (11), a handset (30) including means for voice input (43) and means for voice output (42), a mechanism (39, 41) for docking the handset (30) with the handheld unit (20) forming a docked unit, the docked unit dimensioned to be held in one hand while being used for voice input and voice output, and at least one connection (23, 36) for carrying voice-representative signals between the handheld unit (20) and the handset (30). Device (10) allows telephone-style, voice-driven, user-interface communications both when handset (30) is docked with handheld unit (20), and when handset (30) is detached from handheld unit (20). Handset (30) is made lightweight so that it can be held for an extended amount of time during lengthy phone-style conversations, and may be equipped with a formed support such as a flexible loop (26) to let the user wear handset (30) on one of user's ears for hands-free use as a handset. Device (10) can also be equipped with an image scanner to serve as a digital camera or videophone.
摘要:
A special-purpose appliance (SPA) works in conjunction with a server farm consisting of multiple caching server appliances (CSAs) to supervise a local storage medium (i.e., a shared cache) that is accessible by all the CSAs for storing at least some of the remote objects such as web pages and their embedded objects and/or streaming media objects that have been and/or will be served by one or more of the CSAs to its respective clients. The SPA preferably also determines when to prefetch remote objects such as web pages and their embedded objects and/or streaming media objects that are not currently stored in the shared cache, but which the SPA has determined are likely to be requested in the future by one or more of the CSAs one behalf of one or more of the CSA's respective clients. In that regard, the SPA (and/or PSA) does not merely monitor the file requests from each CSA to the remote servers, but rather monitors and aggregates the individual requests from each client to its respective CSA, for example, by monitoring the access logs of each CSA and using that data to decide what to prefetch into the shared cache from the remote server or servers, what is still of value and needs to be updated, and what is no longer of value and can be replaced. What it prefetches can be based, for example, on links present in an already requested web page, on patterns of recent accesses to web pages and streaming media objects, on user profiles, and on past trends.
摘要:
An integrated circuit having a memory which is reconfigurable as a main memory or as a cache. The integrated circuit may be a microprocessor chip with a memory that is reconfigurable to operate as an on-chip main memory or as an on-chip cache. Alternatively, the integrated circuit may be a stand-alone memory chip that is reconfigurable to operate as a main memory or as a cache.

A distributed shared memory multi-processor system includes a System Control Unit (SCU) which is made up of a system control unit address section (SCUA) and system control unit data sections (SCUDs). The SCU is scalable by dividing the control and data flow functions of the SCU, and then parallelizing the data path. This allows the number of processors in the system to be increased or higher performance processors to be added by increasing the number of SCUDs and reprogramming crossbar switches incorporated in the SCUA and SCUDs. This results in the overall increase of the multi-processor system performance.
