Patent GB-2328982-A (GB)
Title: Tube return sleeve for liquid delivery device
Inventor: DANBY HAL
IPC: F04B43/00
Filed: 1997-09-04
Abstract: The device includes a resilient tube 28 having a cylindrical cross section defining a flow lumen in communication with a reservoir. A compression member 40 or members acting against anvil 17 compress and release a lengthwise segment of the tube to collapse and open the flow lumen. An elastomeric sleeve 22 partially envelops the tubing along at least a portion of the lengthwise segment and has an relaxed state inner diameter less than the outer diameter of the tube and an opening 26 in its anvil side. The elastomeric sleeve biases the segment of the resilient tube to restore it to its cylindrical cross-section when released by the compression member. The sleeve may have handles 32, 34 for retention.

Title: Call selection based on continuum skill levels in a call centre
Inventor: COHEN RICHARD ALAN
IPC: H04M3/00
Filed: 1999-12-07
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.
