Abstract: A heating control system that includes a heating unit with a constant burner and a pulsed burner. The constant burner is configured to remain active during operation. The pulsed burner is configured to toggle between an active mode and an inactive mode. The heating control system further includes a memory operable to store a temperature map that maps temperatures to percentages of a period that the pulsed burner is active and a microprocessor operably coupled to the heating unit and the memory. The microprocessor is configured to transmit a first electrical signal to activate the constant burner, obtain a temperature set point, determine the percentage of the period that the pulsed burner is active using the temperature set point and the temperature map, and transmit a second electrical signal to toggle the pulsed burner based on the determination of the percentage of the period that the pulsed burner is active.

Abstract: A tool extension for a socket wrench includes a jointed, articulated series of square-drive male/female adapter ends with intermediate couplers having hex ball-head and socket joints. Three such intermediate couplers together in one series allow for an overall 90-degrees of flex. Each coupler has a bell body over which a pliable control cover is stretched. Each hex ball head and socket joint is bridged over by a corresponding pliable control cover which then snaps over a retaining lip just under a neck.

Abstract: Various technologies and techniques are disclosed for providing business automation. A business automation system is disclosed that provides contact tracking, split testing, landing page creation, tracking of the performance of printed promotions that are sent by direct mail, and automated follow-up, to name a few examples. Points can be assigned to certain activities within the system, and contacts that have the highest scores based upon those activities can be identified for additional follow-up. A browser-based designer allows for the generation of print materials such as post cards. Multiple layers can be added, manipulated, and/or rearranged. A PDF proof can also be generated. A browser based designer is also described that allows for the generation of landing pages.

Abstract: An accessible URI may be generated in response to determining that an existing valid URI is inaccessible. When a valid URI is determined to be not accessible, then a valid URI may be generated to access content by extracting keywords from the non-query component URI (e.g., directory, domain, port, or fragment, etc.) of the inaccessible URI and using such keywords as a search request or as the query portion of the generated accessible URI.
