Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media. One of the systems includes at least one data store storing listings across a plurality of markets according to a hierarchical, multi-level classification system, the classification system ensuring that users describe listings using consistent terminology, wherein each level in the hierarchy provides additional specificity.

Abstract: A method and apparatus is disclosed for interfacing an asynchronous network with a synchronous network and in particular for efficiently utilizing available bandwidth of a synchronous network transmit opportunity. In one embodiment asynchronous traffic arrives via an asynchronous network at a network device, such as a switch, for transmission over a synchronous network. The traffic is parsed into cells and after switching, a reassembly unit is provided for processing one or more cells buckets. Write operations occur based on an ingress pointer while read operations are controlled by an egress pointer. Upon occurrence of a transmit opportunity on the synchronous network, the entire bandwidth of the transmit opportunity is utilized by loading awaiting cells from bucket memory on to the synchronous network. Sufficient cells are stored in memory between the memory locations identified by the ingress pointer and the egress pointer to insure total utilization of transmit opportunity bandwidth.

Abstract: System and method for dynamically altering bandwidth allocation to each region serviced by a network. Each region is allocated an initial estimated bandwidth on the network and compares instantaneous demand against the allocation. When demand falls below the allocation, the region releases bandwidth so other regions can take advantage of that bandwidth. When demand exceeds the allocation, the region takes advantage of bandwidth released by other regions.

Abstract: A method and apparatus for managing a user's health. In one embodiment, a diet designer for designing a dietary plan, a diet director for directing a user towards a particular meal, and a diet dissector for ascertaining the nutritional content if a user's meal choices are combined in order to provide a robust health management system that operates in real time by evaluating past diet and behavior, to recommend future diet, behavior, and health management. In some embodiments, the invention includes managing a user's health by receiving the user's diet plan, receiving user input about a meal, determining the nutritional content of the meal, and determining how that nutritional content fits into the user's target diet.

Abstract: Alternate routing tables selected according to data packet priority or according to source and destination addresses of data packet. Data packet propagated to egress port according to indicator provided by selected routing table with expediency dictated by data packet priority or priority indicator stored in the selected routing table.

Abstract: An asynchronous transfer mode (ATM) processing system interconnection or termination unit is implemented on a single integrated circuit chip. The unit includes a universal protocol device having Virtual Channel Memory (VCR) for storing ATM cells for segmentation and reassembly, a Direct Memory Access (DMA) controller for interconnecting the VCR to a host unit, and a Parallel Cell Interface (PCI) for interconnecting the VCR to an ATM network. A Reduced Instruction Set Computer (RISC) microprocessor controls the DMA controller as well as segmentation and reassembly of Conversion Sublayer Payload Data Unit (CS-PDU)s and transfer between the memory, the host and the ATM network and other operations of the device using single clock cycle instructions. The operating program for the RISC microprocessor is stored in a volatile Instruction Random Access Memory (IRAM) in the form of firmware which is downloaded at initialization.
