Abstract: A method and system are provided for increasing the efficiency and satisfaction rating of service calls regarding a product. The system can contain a telecommunications system to receiving calls from customers, and for contacting the customers in return. Databases retain information regarding the products sold to the customers, and the customer's calls to the call center. When a given customer calls the call center more often within a given time period, the customer's call is forwarded to another, more specialized queue so that more intensive attention is given to resolve the customer's problem. At that point, the extent and quality of contact with the customer is carefully recorded and correlated with similar problems so that swift resolution of the problem is achieved.

Abstract: A measuring instrument comprising a pair of probe elements moveable relative to one another to vary the spacing between sensing areas of each probe, means for producing a signal representing the spacing of said sensing areas, means for monitoring the rate of change of said signal, and means for recording and/or displaying a value representative of said signal upon the rate of change of said signal reaching a predetermined value. Preferably there is a probe including a probe element and a sheath, the probe element being slideable within the sheath and protruding therefrom by a variable amount, means for producing a depth signal representing the amount of protrusion of the probe element from the sheath, means for monitoring the rate of change of said depth signal, and means for recording and/or displaying a value representative of said depth signal upon the rate of change of said depth signal reaching a predetermined value.
