Flow-aware task distribution in network devices having multiple processor architectures. In one embodiment, the present invention can be used for high bandwidth network processing in an application and flow aware Quality of Service (QoS) network device. In some implementations, the present invention provides a task distribution architecture capable of flow state awareness and link level QoS control.

A three-dimensional (3D) passive element memory cell array provides short word lines while still maintaining a small support circuit area for efficiency. Short, low resistance word line segments on two or more word line layers are connected together in parallel to form a given word line without use of segment switch devices between the word line segments. A shared vertical connection preferably connects the word line segments together and connects to a word line driver circuit disposed generally below the array near the word line. Each word line driver circuit preferably couples its word line either to an associated one of a plurality of selected bias lines or to an unselected bias line associated with the driver circuit, which selected bias lines are themselves decoded to provide for an efficient multi-headed word line decoder.

Embodiments of the invention enable minimum latency site independent real-time video transport over packet switched networks. Some examples of real-time video transport are video conferencing and real-time or live video streaming. In one embodiment of the invention, a network node transmits live or real-tine audio and video signals, encapsulated as Internet Protocol (IP) data packets, to one or more nodes on the Internet or other IP network. One embodiment of the invention enables a user to move to different nodes or move nodes to different locations thereby providing site independence. Site independence is achieved by measuring and accounting for the jitter and delay between a transmitter and receiver based on the particular path between the transmitter and receiver independent of site location. The transmitter inserts timestamps and sequence numbers into packets and then transmits them. A receiver uses these timestamps to recover the transmitter's clock. The receiver stores the packets in a buffer that orders them by sequence number. The packets stay in the buffer for a fixed latency to compensate for possible network jitter and/or packet reordering. The combination of timestamp packet-processing, remote clock recovery and synchronization, fixed-latency receiver buffering, and error correction mechanisms help to preserve the quality of the received video, despite the significant network impairments generally encountered throughout the Internet and wireless networks.

The invention also indicates preferred methods for specific compression and decompression of particular data formats such as digital video, 3D textures and image data using a combination of novel lossy and lossless compression algorithms in block or span addressable formats. To improve latency and reduce performance degradations normally associated with compression and decompression techniques, the MemoryF/X Technology encompasses multiple novel techniques such as: 1) parallel lossless compression/decompression; 2) selectable compression modes such as lossless, lossy or no compression; 3) priority compression mode; 4) data cache techniques; 5) variable compression block sizes; 6) compression reordering; and 7) unique address translation, attribute, and address caches. The parallel compression and decompression algorithm allows high-speed parallel compression and high speed parallel decompression operation. The IMC also preferably uses a special memory allocation and directory technique for reduction of table size and low latency operation. The integrated data compression and decompression capabilities of the IMC remove system bottle-necks and increase performance. This allows lower cost systems due to smaller data storage, reduced bandwidth requirements, reduced power and noise.

Ultrasound applicators able to both image a treatment site and administer ultrasound therapy include an array of transducer elements that can be focused. In several embodiments, an electronically phased array is used for controlling the focal point of an ultrasound beam. The ultrasound beam produced thereby can also be electronically steered. To reduce the quality factor or Q of the array when the array is used for imaging, an electronic switch is selectively closed, placing a resistance in parallel with each of the array elements. A flexible array is employed in several embodiments and is selectively bent or flexed to vary its radius of curvature and thus control the focal point and/or a direction of focus of the array. In another embodiment, each of the transducer elements comprising the array are individually mechanically pivotable to steer the ultrasonic beam produced by the transducer elements.

A communication system (10) supports the provision of a plurality of dedicated communication resources (50–64), such as copper drops, RF links and optical fibers, to dedicated home-gateway devices (44–48) or distribution points (124). The communication resources (50–64) support broadband interconnection (104) between the dedicated home-gateway devices (44–48) or distribution points (124) and an access multiplexor (30) in a network (12). Each gateway device (44–48) or distribution point (124) generally includes a local RF transceiver (84) and associated control logic (80–82) that allows local communication (86) between gateway devices (44–48) and hence statistically multiplexed access (60–64, 89) to multiple communication resources, thereby providing increased bandwidth in uplink and/or downlink directions. With the control logic (80) operable to provide a routing and prioritisation/arbitration function, each gateway (44–48) is able to selectively engage use of supplemental, non-reserved communication resources usually associated with a dedicated ono-to-one connection between the access network (12) and at least one secondary gateway. Physical layer access to information routed via a secondary gateway within a virtual neighborhood network (90–92) comprising several gateways is restricted through an end-to-end encryption algorithm between an originating gateway and, at least, the access multilpexor (30).

Device name conflicts are resolved when adding devices to existing ad hoc networks or when joining two ad hoc networks together. After a connection has been established between a new device to be added and a first member device in the ad hoc network, a name distribution message is transferred by the new device to the first member device. The name distribution message will be passed from member device to member device in the ad hoc network, and at each member device a name conflict check is performed. Device name conflicts are also resolved when joining two ad hoc networks together. The contents of name manager tables of the two respective ad hoc networks must be exchanged. This is accomplished by forming a name distribution message for each name record in the name manager tables of the two devices establishing the connection on behalf of their respective ad hoc networks. Then the name distribution messages formed in each respective ad hoc network are distributed to the other ad hoc network. In the process of distributing the name distribution messages through the other network, any name conflicts are commonly resolved in all of the devices in both ad hoc networks.

Disclosed is a method and apparatus to continuously transmit high bandwidth, real-time data, on a communications network (e.g., wired, wireless, and a combination of wired and wireless segments). A control computing device uses user or application requirements to dynamically adjust the throughput of the system to match the bandwidth of the communications network being used, so that data latency is minimized. An operator can visualize the instantaneous characteristic of the link and, if necessary, make a tradeoff between the latency and resolution of the data to help maintain the real-time nature of the system and better utilize the available network resources. Automated control strategies have also been implemented into the system to enable dynamic adjustments of the system throughput to minimize latency while maximizing data resolution. Several applications have been cited in which latency minimization techniques can be employed for enhanced dynamic performance.
