Publication number: 20110112568Abstract: Recent advances in minimally invasive surgical procedures have created a demand for smaller scale tools with improved performance characteristics. Attempts to scale down modern tools to the meso level (1-5 mm) have caused severe performance losses. Surgical tools of the present invention provide significant improvements in operable range and force application for both grasping and spreading when compared to currently used endoscopic forceps.Type: ApplicationFiled: August 30, 2010Publication date: May 12, 2011Applicant: The Penn State Research FoundationInventors: Mary Frecker, Abraham Mathew, Eric Pauli, Andrew Rau, Jeffrey Kingston, Greg Hayes, Andrew Baranak

Patent number: 7930625Abstract: A computer-implemented method and system for designing shapes for a software module. Drawing software modules typically provide master shapes that are used as templates in creating drawings. The function of master shapes is generally controlled by behaviors. The invention improves upon existing approaches to designing master shapes by providing a uniform procedure for creating master shapes. The present invention supports the creation of a uniform set of behaviors that are stored independently of the master shapes. The stored behaviors are the preferred methods for controlling the functions of the master shapes. Individual stored behaviors can be selected and used to create the characteristics of a master shape. Using a uniform set of stored behaviors that are implemented in a preferred manner facilitates the management and maintenance of the behaviors and the master shapes they control.Type: GrantFiled: January 19, 2007Date of Patent: April 19, 2011Assignee: Microsoft CorporationInventors: Fergal Burke, Abraham Mathew, Heidi McAllister

Publication number: 20100315132Abstract: A distributed charge pump system uses a delay element and frequency dividers to generate out of phase pump clock signals that drive different charge pumps, to offset peak current clock edges for each charge pump and thereby reduce overall peak power. Clock signal division and phase offset may be extended to multiple levels for further smoothing of the pump clock signal transitions. A dual frequency divider may be used which receives the clock signal and its complement, and generates two divided signals that are 90° out of phase. In an illustrative embodiment the clock generator comprises a variable-frequency clock source, and a voltage regulator senses an output voltage of the charge pumps, generates a reference voltage based on a currently selected frequency of the variable-frequency clock source, and temporarily disables the charge pumps (by turning off local pump clocks) when the output voltage is greater than the reference voltage.Type: ApplicationFiled: August 20, 2010Publication date: December 16, 2010Inventors: Fadi H. Gebara, Jente B. Kuang, Abraham Mathews

Publication number: 20100185928Abstract: Extensible architecture and data flow in a web based diagram visualization service is accomplished by enabling a diagram update engine to launch custom data modules. Data modules for data sources that are not inherently supported are created by third parties through a specially defined interface (e.g. .NET® assemblies) and made visible for the web based diagram services and callable from a diagram update engine. Thus, a number of data sources from which diagram data can be retrieved and the way incoming data is manipulated and aggregated is extensible through code.Type: ApplicationFiled: January 21, 2009Publication date: July 22, 2010Applicant: Microsoft CorporationInventors: Abraham Mathew, Philippe-Joseph Arida, Emil Cicos, Raveendrnathan Loganathan

Publication number: 20090199081Abstract: Technologies are described herein for refreshing data-linked diagrams on a server computer and viewing and consuming the refreshed diagrams via a Web browser. A drawing program allows equations within a diagram definition to define how external data is utilized to modify the attributes of a diagram element. When the diagram is published to a server computer, the definition is converted to server-legible definition. A published diagram is generated that includes a diagram representation defined by the server-legible definition. Upon a request for the published diagram, the external data is refreshed and the diagram definition is updated. The equations are recalculated to generate new element attributes. The diagram representation is then updated with the new attributes and returned for display by a client Web browser. An interface provides exploration tools and a client API exposes methods for surfacing external data and annotating the diagram.Type: ApplicationFiled: January 31, 2008Publication date: August 6, 2009Applicant: Microsoft CorporationInventors: Phillippe-Joseph Arida, Po-Yan Tsang, William G.

Publication number: 20090193067Abstract: Technologies are described herein for recalculating data-bound vector graphics on a server computer. A drawing program allows formulas to define how external data is utilized modify the attributes of a shape. When a request is received to publish a drawing to a server computer, any formulas are converted to server-optimized formulas. Once the formulas have been converted to server-optimized formulas, a published drawing is generated that includes the server-optimized formulas, a representation of the drawing in a vector format, and data identifying bindings between shapes within the drawing and external data. When a request to view the published drawing is received, the data bindings for the drawing are refreshed. The server-optimized formulas are then recalculated using updated values to generate new values for the shape attributes. The vector representation of the drawing is then updated with the new values and rasterized for display in a browser.Type: ApplicationFiled: January 30, 2008Publication date: July 30, 2009Applicant: MICROSOFT CORPORATIONInventors: Abraham Mathew, Heidi McAllister, Michael Joe Woolf

Patent number: 7564458Abstract: A facility for linking data from an external data source to shapes in a diagram is provided. The facility is implemented as a component of a graphical visualization program, and provides a modeless data window that is operable to display data from a data source through a two dimensional table. Users can use the facility to import data from a data source and display the imported data in the modeless data window. Users can then use the modeless data window to select and drag rows displayed in the modeless data window onto shapes on a drawing surface of the graphical visualization program to link the dragged rows to the shapes. Users can also drag rows displayed in the modeless data window onto a blank section of the drawing surface to create shapes on the drawing surface and link the rows to the created shapes.Type: GrantFiled: December 15, 2004Date of Patent: July 21, 2009Assignee: Microsoft CorporationInventors: Matthew T.
