Abstract: A framework is described for providing a service to a customer via a Interactive Voice Recognition system (IVR) using natural language expressions. The expressions are evaluated using rules-based programming rules. Evaluated expressions determine an eligibility of a business service to be offered to a customer. Interaction with the customer comprises selecting a semantically correct natural language expression from an appropriate vocabulary database.

Abstract: Techniques are provided for processing a request. When the request is to read a data unit, information regarding the closest physical block locations is returned. When the request is to write to the data unit, information regarding one or more source block locations is returned, wherein the write is applied to one or more source blocks of the data unit. When a number of requests for the data unit exceed a threshold level and at least one quality of a service policy is not being met, a copy of the one or more source blocks of the data unit is created at a location selected based on proximity to at least one client computer from which the number of requests are high.

Abstract: In a first aspect, a sensor enables the efficient measurement of conducting film thickness by providing a capacitance probe with an eddy current coil placed co-axially within the capacitance probe. The capacitance probe senses the proximity of the sensor to the conducting film, the proximity measurement enabling an eddy current detector coupled to the eddy current coil to measure the thickness of the conducting film. More specifically, the eddy current coil is excited by a radio frequency generator and induces eddy currents in the conducting film. The resulting eddy currents are detected using the eddy current coil and the eddy current detector. The resultant eddy current sensing is indicative of sheet resistance that relates to film thickness. By providing both capacitance and eddy current sensing measurements, conducting film thickness may be quickly and accurately determined. Numerous other aspects are provided.
