Abstract: A method and apparatus that allows different likelihoods of call completion during very heavy call loading conditions to be supplied to different customers. Customers are assigned to different levels of service and these levels of service are used to manage call completion in throughout the telecommunication network during very heavy call loading periods. Thus, a securities broker may have a higher likelihood of completing a call near the close of a trading session than the average telephone customer. However, each caller may be offered an opportunity to immediately increase his or her level of service and thus likelihood of completing a call to the highest available level if a call is not completed at the caller's lower level of service.

Abstract: An apparatus for a pen-based input system, such as personal communication device or notepad computer, which shields against RFI/EMI fields causing problems either in the internal electronics or in the environment surrounding the system. A digitizer used in such a system must be able to sense a location of a special pen used for inputting information. This digitizer is also a source of RFI/EMI fields. A shield of such RFI/EMI fields must allow the digitizer to work and reduce the amount of RFI/EMI released to the environment. A special transparent conductive layer, such as a coating of Indium-Tin-Oxide, beneath the pen input protective plate performs these two necessary functions. The conductive layer also shields the system internal electronics from external RFI/EMI sources such as attached cellular telephone systems or radio LAN systems.
