Patent number: 9933929Abstract: A device may generate a graph of a set of elements included in a graphical user interface. An attribute of an element, of the set of elements, may be represented by a vertex of the graph. A layout relationship associated with the set of elements may be represented by an edge of the graph. The device may detect a change to the graphical user interface from a first display condition to a second display condition. The device may determine another vertex location for the vertex corresponding to another attribute for the element based on detecting the change from the first display condition to the second display condition and based on the graph of the set of elements. The device may provide, for display, the set of elements in the second display condition based on the other attribute for the element.Type: GrantFiled: April 2, 2015Date of Patent: April 3, 2018Assignee: The MathWorks, Inc.Inventors: Alice Pitsillides, Christian A.

Patent number: 8307328Abstract: A system and method encapsulates selected functionality of a programming environment, defines an interface to the encapsulated functionality, and utilizes the encapsulated functionality from within an add-on toolbox to the programming environment through the interface. Objects may be constructed from the selected functionality of the programming environment. The functionality may be built-in or custom designed functionality. The objects are registered with the add-on test toolbox, and made available to a user of the add-on toolbox. The user may enter information into a user interface specifying selected functionality and its properties. An object manipulation engine receives the to information entered into the user interface, and uses it to issue calls through the interface to construct the objects and invoke one or more of the methods.Type: GrantFiled: April 2, 2008Date of Patent: November 6, 2012Assignee: The MathWorks, Inc.Inventor: Christian A.

Patent number: 8265916Abstract: A method for testing a system under test includes defining a test having a number of test elements where at least one of the test elements corresponds to a simulation model with a metric setting. A test vector is defined for the test, and it is used to determine a number of test iterations. The metric setting of the simulation model is mapped to a test variable, and when the test is run metric data is generated from the simulation model during each test iteration. The metric data generated for each test iteration is accumulated and displayed.Type: GrantFiled: January 10, 2008Date of Patent: September 11, 2012Assignee: The MathWorks, Inc.Inventors: Christian A.

Patent number: 8046201Abstract: A method of creating and using a hardware independent communication interface block for block diagram environments is disclosed. The communication interface block includes user-selectable parameters controlling how a system being modeled by a block diagram communicates with image and data acquisition devices and control instruments or other electronic device interfaced with an external system. Based on the user selected parameters, the communication interface block calls an appropriate constructor to create an instrument object or acquisition device object which is used to enable communication with the control instrument or acquisition device respectively. The instrument object/acquisition device object calls a software driver appropriate for the hardware interface of the control instrument/acquisition device. The use of a common interface block provides scalability and ease of use to the block diagram environment when interacting with control instruments and acquisition devices.Type: GrantFiled: May 14, 2004Date of Patent: October 25, 2011Inventors: Melissa J.

Patent number: 7886307Abstract: A method transfers data from a data source to multiple data sink objects. The data acquired from the data source is encapsulated into a data object. Identification information of the data object is posted to a data server. The data server shares the identification information with the data sink objects that are registered with the data server. The data sink objects access the data object with the identification information at execution time. A counter indicates the number of data sink objects that currently use the data object. The data object is removed from the memory of the computer systems when the counter indicates that the data object is no longer used by the data sink objects. Alternatively, the data object that is no longer used may be stored in a separate memory location of the computer systems for a future use.Type: GrantFiled: September 26, 2003Date of Patent: February 8, 2011Assignee: The MathWorks, Inc.Inventors: Loren Dean, Robert DeSonia, John Holohan, Christian Portal, Dave Tarkowski
