Abstract: A demultiplexer (10) includes an input stage (12) that receives a serial data stream having a plurality of m-bit sections at a first clock rate. The input stage converts successive n-bit portions of each m-bit section into a first nbit parallel output at a second clock rate. An intermediary stage (14) receives the first n-bit parallel output and generates a second n-bit parallel output at the second clock rate. The first n-bit parallel output corresponds to a different portion of an m-bit section than the second n-bit parallel output. An output stage (16) receives the first n-bit parallel output from the input stage (12) and the second n-bit parallel output from the intermediary stage (14). The output stage (10) places the first n-bit parallel output onto an output bus (36) having a width of m-bitlines at an earlier instance in time than the placement of the second n-bit parallel output.

Abstract: Low-resistant contacts (205) are made from the surface of a semiconductor component (201), down into the substrate (203) thereof, by means of etching a hole down into the substrate (203), which then, for example, by means of CVD deposition is filled with a metal, e.g. tungsten. Moreover, by further locating such substrate contacts at close distances around a component (201) or a block or a group of components, a very good electrical shielding against other components or blocks of components located on the same substrate is obtained.  Shielding can also be obtained vertically upwards by means of applying a metal layer on top of the component. The metal plugs obtained in this manner can also be used for lateral shielding of electrical signal conductors in a semiconductor structure.

Abstract: An apparatus (figure 2) and method for forming a digital optical disc master from a disc having a substrate (300) coated with a photoresist coating (320).  The method includes irradiating the surface of the photoresist material (320) with a laser beam (310) at a multiplicity of pit locations over the substrate (300) causing the photoresist material (320) to react to the laser radiation (310) to form at least three different discrete levels at the multiplicity of pit locations relative to the surface of the substrate (300) due to the dose of radiation applied being calculated to react with the photoresist to a depth equivalent to the discrete levels. The exposed photoresist is then developed to achieve the pits having the different discrete levels. A further method is disclosed for equalization and compensation for intersymbol interference between adjacent pits.

Abstract: Selection of a suitable call-center agent (106-108) to handle a call is based on which available suitable agent's handling of the call will tend to optimize call wait times. When a call needing a particular skill becomes available (200)) all skills of agents in the agent queue (131-139) corresponding to the particular skill are determined (202, 204). The agent queues corresponding to the determined skills are checked (206) to determine which ones identify only one agent. For each available agent having the particular skill, the number of agent queues which identify this agent as their only agent is computed (208). The available agent having the lowest computed number is selected (210) to handle the call. This minimizes the number of skills that will be left without an available agent to handle subsequent calls, and thus tends to maximize the probability that a next call will also have a suitable agent already available and not have to wait for one to become available, thereby optimizing call wait times.
