20130033291 | MULTI-OUTPUT-RESISTANCE SWITCH DRIVER CIRCUITS - A switch circuit can include an impedance selection switch and a multi-output-resistance switch driver. The impedance selection switch can electrically connect an impedance to an input of an amplifier in response to a driver output signal, and include at least one transistor. The multi-output-impedance switch driver may provide the driver output signal to the switch, and have a first, relatively higher output resistance when providing a first logic state of the driver output signal to turn on the switch, and a second, relatively lower output resistance when providing a second logic state of the driver output signal to turn off the switch. The ratio of the first output resistance to the second output resistance can be greater than a selected predetermined ratio value. | 02-07-2013 |
20150070200 | System, Method and Recording Medium for Analog to Digital Converter Calibration - A calibration system for an analog-to-digital converter (ADC) an internal ADC that receives an analog input and converts the analog input to digital multi-bit data. The calibration system also includes a reference shuffling circuit that shuffles reference values of comparators of the internal ADC. Further, the calibration system includes a calibration circuit that calibrates the comparators of the internal ADC. The calibration system includes a digital block that measures an amplitude based on the digital multi-bit data. Additionally, the calibration system includes calibration logic that controls the calibration circuit based on an output of the digital block. | 03-12-2015 |

20140167738 | Electric Meter Base Level Printed Circuit Board - Techniques for construction of an electric meter base level printed circuit board (PCB), such as for use in an electric consumption meter, are described herein. A plurality of heavy copper traces may be embedded in the PCB, thereby eliminating the need for heavy copper bar between connectors and components on the board. In one example, a PCB includes connectors for incoming and outgoing line and neutral conductors. The PCB may include a current measuring component, mounted on the PCB, to communicate with metrology circuitry. The PCB may include one or more switches, configured to regulate electrical service. Heavy electrical traces may be embedded in the PCB to connect the connectors and various components mounted on the PCB. The heavy electrical traces are sized to allow passage of currents that may be in excess of 100 amps. | 06-19-2014 |
20140266171 | ELECTRICITY METER HAVING MULTIPLE HALL DEVICES - Disclosed is a metrology assembly that utilizes a multi-Hall effect device configuration which eliminates the necessity of a magnetic concentrator. In some embodiments, the metrology assembly includes a substrate or support platform configured to support at least two Hall effect devices per phase of an electricity meter. The metrology assembly may further include one or more electrical conductors coupled to the substrate and configured to conduct electric current. The at least two Hall effect devices may be coupled to the substrate at opposing sides of an associated electrical conductor, each Hall effect device being configured to detect a magnetic field created by the electric current of the associated electrical conductor, and to generate an output. | 09-18-2014 |

20110221764 | LAYING OUT AND CROPPING IMAGES IN PRE-DEFINED LAYOUTS - A layout definition file is created that stores data defining image layouts. An application program provides a user interface for laying out images and associated text using the contents of a layout definition file. The user interface includes a canvas onto which a user may place one or more images and a layout gallery through which a user may select a pre-defined layout. The layout gallery includes selectable visual representations corresponding to the pre-defined layouts. When one of the visual representations is selected, the corresponding pre-defined layout is applied to images on the canvas. Alternatively, one of the visual representations may be selected to cause placeholders for images and text in the corresponding pre-defined layout to be placed on the canvas. Images and text can be added to the layout by using the placeholders. Mechanisms are also provided for cropping images for use in a pre-defined layout. | 09-15-2011 |
20110225548 | REORDERING NODES IN A HIERARCHICAL STRUCTURE - This disclosure describes a user interface and methods for quickly and easily modifying graphical content. Specifically, content having a hierarchical format may be received in a content pane. The hierarchical format may include one or more hierarchical levels and a plurality of content portions occupying one or more hierarchical positions within each of the one or more hierarchical levels. Further, a graphical definition may be applied to the content creating graphical content. As will be appreciated, the graphical content may comprise a hierarchical structure corresponding to the hierarchical format of the content. The hierarchical structure may include a plurality of nodes occupying one or more node positions within each of one or more node levels. A content portion occupying a hierarchical position may be reordered within a hierarchical level and may automatically cause a corresponding node in a corresponding node position to be reordered within a corresponding node level. | 09-15-2011 |
