Methods and apparatus for work management and routing
Methods and apparatus for service-level based and / or skills-based assignment of a work item to one (or more) of a plurality of resources based on fitness, for example, of skills required by the former to those provided by the latter. Assignment takes into account the level of stress on the work item and / or resources, such that the number of resources fit for assignment varies as the level of stress varies. Systems according to the invention can be used, by way of example, to route a call or other request made by a customer to a service center. The requirements for processing the call (determined, for example, by an incoming call operator) are matched against the skill sets of available customer service agents, taking call and / or resource stress levels into account. For example, some implementations may match an incoming call having a low stress factor (e.g., a newly received call from a standard customer) to a smaller pool of agents with both required and desired skills, while assigning a call with a higher stress factor to a larger pool of agents with at least required skills. Other embodiments may match an incoming call having a low stress factor to the larger pool of agents having at least the required skills, while assigning a call with a higher stress factor (e.g., a call from a priority customer) to an agent from the smaller pool of agents who have both required and desired skills.

Method and system for performing built-in self-test routines using an accumulator to store fault information
InactiveUS7260758B1Increase productionCharacteristic defectElectronic circuit testingStatic storageMemory addressStress conditions
A test system includes a built-in self-test (BIST) circuit and a stress applicator for use in analyzing a memory array. The stress applicator applies a selective set of stress factors to the memory array, such as temperature and voltage conditions. The BIST circuit executes a test routine on the memory array to detect the presence of any faulty memory address locations that may arise under the prevailing stress condition. A full testing cycle involves iterative repetition of the functions performed by the stress applicator and BIST circuit, with variations in the stress factors across the testing iterations. An accumulator cumulatively stores the fault information generated by the BIST circuit during each testing iteration. Following completion of the testing cycle, a repair operation is performed by a built-in self-repair (BISR) circuit to remap the faulty memory address locations indicated by the accumulator to redundant memory address locations.

An information handling system power supply system has a plurality of power supply units (PSUs) with outputs connected in parallel and a current balancing circuit for equalizing current from these outputs. A pseudo output current value may be added to the actual output current value for each PSU so that the parallel load sharing current balance system thinks all of the PSUs are sharing the load equally. This allows simple and inexpensive paralleling of differently rated PSUs without complex load sharing circuitry. Also, PSU stress factors may be easily compensated. For each PSU there may be a first voltage, VS1, generated that is proportional to the output current of the respective PSU. A pseudo current bias voltage, VIbais, is added to the first voltage, VS1, to produce a biased second voltage, VS2, (VS2=VS1+VIbais). The biased second voltage, VS2, now represents the apparent current output of the respective PSU when current load balancing each PSU of the power supply system. A standard current balance circuit may now balance all of the PSUs for what it thinks are equal output currents from each of the parallel connected PSUs.
