Title: Call selection based on continuum skill levels in a call center
Inventor: FOSTER ROBIN H
IPC: H04M3/60
Filed: 1999-11-16
Abstract: A call selection process in a call center is configured to utilize a continuum of skill levels, in one or more categories, for a given multi-skill agent. In an illustrative embodiment, categories of levels are associated with skills supported by the given agent, with each of the categories including a level, e.g., a numerical value, for each of the skills. The levels are used in a call selection computation that determines which of a number of waiting calls should be delivered to the agent. The categories may include, for example, a speed category including levels indicative of the speed at which the agent can process calls for each of the corresponding skills, a yield category including levels indicative of results likely to be obtainable by the agent for each of the corresponding skills, and a preference category including levels indicative of preferences of the agent for calls requiring each of the corresponding skills. The process may involve selecting different subsets of one or more of the categories in a given set of categories for use at different times, depending on factors such as call volume. The call selection computation may involve, for example, computing a value for each of the skills, as a function of the corresponding level or levels and a wait time measure, e.g., a current wait time, a predicted wait time, or a ratio of predicted wait time to a service objective, for a call in a corresponding skill queue.

Abstract: A method of operating a mass spectrometer and a mass spectrometer are provided. A first mass analysis stage, a fragmentation stage, an additional stage operable as a mass analysis stage, and a final mass analysis stage are connected and are operable either intermittently as a mass analyzer or continuously as a detector. The method comprises operating the apparatus in one of two modes, each comprising first selecting an ion with a predetermined mass to charge ratio and then causing fragmentation of that ion. The first mode includes: (1) passing the ion stream, including fragment ions, into the additional stage and operating the additional stage as a mass analyzer at a relatively low pressure to select ions having a desired mass-to-charge ratio; and (2) passing the ion stream into the final mass analysis stage and operating the final mass analysis stage as a detector to detect the total ion current received therein, whereby the ion current detected in the final mass analysis stage is maximized for the selected mass-to-charge ratio.      The second mode includes: (a) passing the ion stream, including fragment ions into the additional mass analysis stage, and operating the additional mass analysis stage as an ion guide at a relatively high pressure to cool and focus the ions, whereby substantially all ions pass therethrough; and (b) operating the final mass analysis stage as a mass analyzer, to effect mass analysis of the ion stream received therein.

Title: Echo canceller employing dual-h architecture having variable adaptive gain settings
Inventor: LABERTEAUX KENNETH P
IPC: H04M9/08
Filed: 1998-11-13
Abstract: An echo canceller circuit for use in an echo canceller system is set forth that provides sensitive double-talk detection. The echo canceller circuit comprises a second digital filter having adaptive tap coefficients to simulate an echo response occurring during the call.  The adaptive tap coefficients of the second digital filter are updated over the duration of the call using a Least Mean Squares process having an adaptive gain a. A channel condition detector is used to detect channel conditions during the call. The channel condition detector is responsive to detected channel conditions for changing the adaptive gain a during the call. For example, the channel condition detector may detect the presence of a double-talk condition and set the adaptive gain a to zero. Similarly, the channel condition detector may detect the occurrence of a high background noise condition and set the adaptive gain a to a level less than 1 that is dependent on the detected level of the background noise. Other similar channel conditions and corresponding adaptive gain settings may likewise be utilized.

Abstract: A belt conveyor for conveying granular material comprises a tube and a hopper. Guide members guide the belt from a flat orientation as the belt leaves the lower roller into a cupped orientation as the belt enters the hopper. The cupped orientation ins maintained by sliding contact at an interface between the lower surface of the belt and the hopper walls as the belt passes through the hopper. Left and right baffle members are attached along the hopper side walls and thereby prevent the granular material from sliding down the hopper walls into contact with the interface between the lower surface of the belt and the hopper walls. The belt has a width that is substantially fully exposed to granular material entering the hopper. A method of increasing the capacity of a belt conveyor comprises reducing the width of the flashing covering belt side portions.
