    • An apparatus is provided for processing a sequential stream of fixed length cells received via a slotted data transmission medium. The cells may be asynchronous transfer mode (ATM) cells. The apparatus utilizes a demultiplexer to create N (N=2,3,4 . . . ) sub-streams of cells from the input stream and to pass each sub-stream to one of N processing paths. Each of the processing paths is identical and they operate in parallel. The cell sub-streams are fed into the processing paths in a chronological, staggered manner where the time between one sub-stream being fed into its processing path and the next sub-stream being fed into another processing path is equal to the slot duration of the transmission medium. Finally, the apparatus utilizes a multiplexer to combine the processed sub-streams into an output stream which maintains both the sequential order of the cells and their arrangement in the slots of the slotted transmission medium.

    • For testing the integrity of conducting lines on or in a substrate, the following steps are executed: (I) Selected pads are irradiated by a focused optical beam so that they are positively charged due to photon-assisted tunneling of electrons from those pads. The charges propagate through existing conductors so that all selected pads and all pads connected to them assume a specific voltage. (II) The whole surface is irradiated by a flooding optical beam. Photon-assisted tunneling of electrons will now occur from those pads which were not charged previously. (III) The tunneling electrons excite an electroluminescent layer whose illumination reveals the spatial distribution of uncharged pads. This method is performed in air under atmospheric conditions and allows completely contactless testing of circuitry to detect line interruptions as well as shortcuts between separate lines. It is suited for surface lines, buried lines and for via connections.

    • A system for hierarchical occupancy based congestion management includes a buffer embodied in a computer readable storage medium including a plurality of buffer units for storing packets of a data flow received from sources. The system includes a buffer manager that stores information about the packets stored in the buffer, including a selection criterion associated with each of the plurality of sources and a congestion estimator that monitors a congestion level in the buffer. The system also includes a occupancy sampler that randomly selects at least two occupied buffer units from the plurality of buffer units and identifies the source of the packet stored in each of the occupied buffer units and a congestion notification message generator that generates a congestion notification message; wherein if the congestion level in the buffer exceeds a threshold value the congestion notification message is sent to the identified source with a higher selection criteria.
