Abstract: A gas flow control and igniter switch assembly for a gas appliance includes a valve body having a stem, an igniter activating switch and a knob, wherein the igniter is activated upon depressing of the knob a predetermined distance. The igniter switch is preferably constituted by a multi-piece outer casing within which is mounted multiple igniter contacts, an electrical connector, and an activating member. The activating member carries the electrical connector and is biased to a position which maintains an electric circuit to the igniter open. The multi-piece outer casing is adapted to be snap-fittingly secured together and mounted about the stem of the valve. Preferably, the stem extends freely through the outer casing but press-fittingly receives the activating member such that the activating member moves in axial unison with the stem. A knob is employed for rotating the stem to regulate the flow of gas from an inlet to an outlet of the valve, while also permitting the valve stem to be depressed in order to initiate a sparking operation at an electrode for a respective gas burner of the appliance.

Abstract: An arrangement for monitoring contact-center performance automates the monitoring process by using a database schema that records the contact center to be monitored, its skills, the locations where the skills are located (in the case of a distributed contact center), the objective or target value for a given skill attribute (such as average speed of answer, maximum delay, etc.), the acceptable deviation from the objective (tolerance), the maximum acceptable deviation between locations (in the case of a distributed contact center), the periodicity or frequency of the monitoring, and the comparison operator needed to determine how a given observed or actual value for the skill attribute is to be compared with its specified objective and tolerance. Monitoring is then effected as follows. Periodically, the contact center is automatically polled for performance data, actual values of the skill attributes are computed therefrom, and the actual values, the objective values, and the tolerances are used in a meta formula to determine the performance metrics. When skills are distributed across several locations of a distributed contact center, the arrangement determines the performance metrics for each location, and further determines whether the maximum deviation between the locations of their actual values exceeds the maximum acceptable deviation. Results indicating performance outages are sent to a party that is responsible for the contact center.

Abstract: Systems and methods for producing a digitally-computed acknowledgement of a delegated download event are disclosed. An information owner, such as the issuer of a smart card, delegates an information download to a third party. The information is downloaded from the third party to an information device, such as a smart card. The computed acknowledgement is a digital "seal" or signature (depending upon the type of cryptographic algorithm used). The seal or signature is preferably a cryptogram generated by the information device using cryptographic keys resident on the information device itself. This acknowledgement is then made available to the information owner, who may then test the cryptogram to determine whether the third party successfully completed the software download.
