Abstract: A system for measuring the conductivity of a flexible media positioned between a conductive backing and a conductive roller, wherein the conductive roller contacts the flexible media in a roller contact region. A pressure control mechanism presses the conductive roller against the second surface of the flexible media with a specified contact pressure, and a motion control system provide a relative motion between the conductive roller and the flexible media. A resistance measuring system connected to the conductive roller and the conductive backing measures the conductivity of the flexible media within the roller contact region. A data recording system records the measured conductivity of the media as a function of position.

Abstract: A method for adjusting an extent of contact between a fountain roller mounted within a pivotable ink pan and an anilox roller in a flexographic printing system, the pivotable ink pan being adapted to pivot around a pivot axis disposed proximate to a first end of the pivotable ink pan. The pivotable ink pan is positioned to provide a predetermined gap between the anilox roller and the fountain roller by inserting a shim between the fountain roller and the anilox roller. The position of the pivotable ink pan is adjusted by adjusting a height of a distal portion of the pivotable ink pan by a predetermined amount that is known to close the predetermined gap to a desired extent. The position of the pivotable ink pan is then locked such that the distal portion of the pivotable ink pan is maintained at the adjusted height.

Abstract: A flexographic printing system including an ink pan configured to pivot around a pivot element having a pivot axis. A first bracket affixed to the ink pan is configured to rest on the pivot element, and a second bracket is affixed to the ink pan in an adjustable position and is configured to constrain motion of the ink pan to a pivoting motion around the pivot axis. A fountain roller is mounted on the ink pan and is at least partially immersed in the ink in the ink pan for transferring the ink to an anilox roller having a patterned surface for transferring a controlled amount of ink from the ink pan to the flexographic printing plate. A height adjustment mechanism is provided for adjusting a height of a distal portion of the ink pan to control the extent of contact between the fountain roller and the anilox roller.

Abstract: A flexographic printing system uses a flexographic printing plate to produce printed patterns on a substrate. A fountain roller partially submerged in ink in an ink pan is used to transfer ink to an anilox roller, which transfers a controlled amount of ink to the flexographic printing plate. An ink recirculation system is used to reduce variability in system performance resulting from ink viscosity changes. A recirculation pump moves ink through an ink recirculation line connected to an ink recirculation port in an ink pan. The design of the ink pan and ink recirculation port is arranged so that an opening of the ink recirculation port is fully covered by the ink during printing by the flexographic printing system.

Abstract: An ink transfer pressure between cylinders in a flexographic printing system is controlled to provide consistent image quality. A flexographic printing plate is provided that includes an image region arranged to print an image pattern having printed image features and a pressure characterization region outside the image region arranged to a print pressure characterization pattern. Ink is transferred from an anilox cylinder to the flexographic printing plate with a first transfer pressure, and from the flexographic printing plate to a recording medium with a second transfer pressure. An optical property of at the printed pressure characterization pattern is measured and used to adjust one or both of the first and second transfer pressures.

Abstract: A system having a graphical compiler connected to a function block engine. The graphical compiler may convert graphical information to non-graphical information. A resources allocation module may be connected to the function block engine and the compiler. Also, a function block execution list may be connected to the compiler and the function block engine. A user interface may be connected to the compiler.

Abstract: A set of multiple prepaid calling cards that are associated with a single account is disclosed. A predetermined amount of minutes is associated with the set of cards. Cards within the set can be used simultaneously and extract minutes from the account in predetermined increments. Each card can use the same Personal Identification Number (PIN) or each card can have its own unique PIN. In some instances, any card in the set can recharge the account, (i.e., add more minutes to the account), or in some embodiments, only a control card can add minutes to the account.

Abstract: An electronic device such as an HVAC controller that accounts for internal heating in determining an environmental condition such as temperature or humidity in the space surrounding the HVAC controller. The HVAC controller may calculate a transient heat rise value that is based upon a powered time period and a first order time lag, especially during a time period before which the HVAC controller reaches a steady state temperature condition.

The catheter includes a one-piece inlet housing with integral mounting fins for attachment to the catheter housing.

Abstract: The performance of an HVAC system in a building is monitored by connecting a thermostat to an alarm system which is equipped to provide notification of alarm conditions through telecommunication or other direct means to some responsible entity. The alarm system access to telecommunications is employed to forward indicators of HVAC fault to predetermined offsite locations from where corrective action can be provided. The system includes a presumed fault condition processor which employs data from the thermostat to indicate to the alarm system that notification should take place.

Abstract: A method and system for improving indoor air quality by controlling the circulation of air by a system fan of a conventional environmental control system in order to achieve a minimum circulation cycle. The method and system prevent nuisance short cycling of the system fan by extending the circulation cycle when the method and system predict the system fan will be activated by the environmental control system for heating or cooling shortly after the termination of the controlled circulation.
