Abstract: A system for allocating bandwidth resources among various mobile stations which are wirelessly connected to a base station. The length of the data queue in each mobile station is determined and information regarding that length is placed in a field in the outgoing data packet. When it is received in the base station, this field is decoded and the queue length information used to allocate bandwidth resources among the mobile station connections. This allows a very quick response to data queue lengths and accordingly better service.

Abstract: A method for scheduling data packets from a plurality of flows into a single flow. Data packets are broken into data segments and assigned a slack value based on how long the segment can wait until transmission begins. Every time a transmission opportunity passes, the slack value of the segment is decreased. The scheduler prioritizes the segments based on their slack value.

Abstract: A method for analyzing an integrated circuit (IC). At least a portion of a layer of the IC is scanned using high magnification, to obtain images of the IC. The images are registered to create a mosaicked image. An IC layout database is created in the form of a set of polygons from the mosaicked image, where the step of creating the IC layout database is performed after, or pipelined with, the registering step. The process is repeated for plural IC layers, as necessary. Polygon sets from each layer are vertically registered into alignment with minimal distortion. A netlist or schematic diagram is generated to represent the scanned IC portion based on the registered set(s) of polygons.

Abstract: A method of analyzing at least a portion of an integrated circuit (IC) comprised of the steps of automatically: (a) scanning at least a portion of a layer of an integrated circuit using high magnification to provide first digital signals representing pixel amplitudes, (b) extracting features of interest from the first digital signals to provide second digital signals representing values of groups of pixels defining the features of interest, (c) modifying the second digital signals representing adjacent features of interest from step (b) so as to mosaic the features of interest and providing third signals representing a seamless representation of the layer, (d) repeating steps (a), (b) and (c) for other layers of the integrated circuit, whereby plural third signals representing plural ones of the layers are provided, (e) registering the plural third signals relative to each other so as to represent vertical alignment of the layers by determining features of interest representative of IC mutual interconnection
