Abstract: A displacement measuring system to measure the displacement of a structural object that includes a transmitter having a signal generator and an antenna wherein the antenna is securable relative to one of a displaced object and a support. The antenna defines a transmitter axis that is parallel to the displacement axis of the object and a centerline that is perpendicular to the displacement axis. The system further includes a first receiver and a second receiver having antennas securable relative to the other of the object and the support. The receiver antennas are positioned along a receiver axis that is parallel to the displacement axis and being spaced along the receiver axis on either side of the center line. The receiver antennas are configured to detect a signal emitted by the transmitter. The system further includes a phase detector to triangulate phase change and calculate object displacement.

Abstract: A capacitively-coupled strain sensor and methods are presented in which the strain on a structure is measured by the varying capacitance created by the displacement of one or more boards attached to the structure.

Abstract: A method, program and system for displaying the consequence of an input in a graphical user interface (GUI) are provided. The invention comprises displaying a GUI including a plurality of interaction control mechanisms (controls) having a selected or a deselected state. An input to a first control may cause a change in state to at least one other of the plurality of controls. Responsive to a first input at the first control (e.g., holding down a mouse button with the pointer on the first control), the invention displays a preview of the change in state of the plurality of controls that would occur if a second input is made at the first control (e.g., releasing the mouse button with the pointer still on the first control). If the user does not want the previewed change in state to occur, the user has simply to avoid making the second input (e.g., move the pointer off the first control before releasing the mouse button).

Abstract: A wave generating device and method of using the same wherein the device is for producing a shear wave in a ground layer wherein the generated wave emanates from a bore hole in the ground layer and passes through the ground layer toward a receiver spaced from the bore hole. This wave having a given waveform and the bore hole being defined by at least one bore wall that extends from a surface of the ground layer to a bottom extent of the bore hole. The device including a driver having an outer layer extending in a longitudinal direction along a longitudinal axis and having a radially outwardly facing surface generally parallel to the longitudinal axis which is configured to engage an associated bore wall of an associated bore hole.

Abstract: A computer system employs a graphical user interface and pointing device to allow a user to drag icons, representing data or objects, without holding the mouse button, or other key, actively depressed. The system allows the user to select and add icons, from a displayed window, to a "drag set". Multiple "drag sets" are linked to a "lazy drag" set, the contents of which may be moved to a target location. At the target location, the user decides what operation is to be performed with the data or objects linked to the "lazy drag" set.

Abstract: A method and system are disclosed for integrating multimedia presentations into an object oriented user interface which includes multiple polymorphic objects which each have associated encapsulated data and functionality. Multiple separate user selectable data views are defined for each object which provide different views of the data associated with an object. Selection by a user of an audio or video data view for an object results in the provision of a multimedia presentation by automatically coupling audio or video data to an appropriate device. Audio data may be directly associated with an object or derived in response to selection of an audio data view, by means of a text-to-speech process, or other similar technique. Encapsulating multimedia data within an object integrates multimedia presentation capability within an object without requiring separate audio or video objects which must be manipulated by the user.

Abstract: A visual procedure aides the program builder in linking objects in a visual application builder where the objects are on different pages of the application builder notebook. When the target object is on another page of the notebook, the user selects the source object. The user then flips the notebook page. During the page flipping, the selected source object is shown as an outline shadow with a page number under it. If the new page is shown with the desired target object on it, the user drags and drops a link between the shadow source object and the target object to make a connection. If the user flips to the source object page, then the target object will become the shadow object with a page number label next to it. If the shadow object is too big and covers the target object completely or for any other reason, the user may want to optionally use the outside page connector technique. This can be done by dragging and dropping the link from the source object to any point outside the notebook.

The transducer includes a housing, a piezoelectric crystal assembly received within the housing and positioned so that the piezoelectric element contacts the base surface of the housing, and a retaining member which grippingly engages the housing and applies a compressive force to the piezoelectric crystal assembly. The retaining member includes a hub portion and a plurality of angularly spaced-apart arms extending radially outwardly from the hub portion. The arms are positioned with respect to the hub portion so as to grippingly engage the inner surface Of the housing and causing the retaining member to apply a compressive force to the piezoelectric crystal assembly.

Abstract: A technique for the display and manipulation of windows resembling real-word objects in an object-oriented graphical interface displays windows without substantial borders, continuously displayed title bars, scroll bars, and various graphical icons and symbols that surround the information in conventional windows. Window components are provided to support window manipulation functions such as MOVE, SIZE and CLOSE. A slide-up title bar with a close-box is generally kept hidden behind the window until dragged-up by the user when desired. Thin borders, which are used to conserve screen real estate, may be manipulated to perform a CLOSE operation with a "flicking" gesture or perform a SIZE operations by dragging the window's border. Moving a window may be performed by clicking a "whitespace" area and dragging to a desired destination.

Abstract: Objects are provided with handles representing the most frequently used events and actions for that particular object. Each handle has a label indicating the name of the event or action it represents. The functions of the objects can be connected together using these handles. In addition, tile events and actions that are shown as handles can be changed by selecting them from a list. The display of the handles and/or labels can be turned off if desired.

The method includes the steps of displaying the visual switch on a display and visually connecting the output to a selected one of the second inputs in response to the first input. The method includes the computer-implemented steps of displaying the first and second inputs on a display, visually linking information to at least one of the second inputs, and visually linking a value to one of the first inputs to set the visual switch object, thereby selectively connecting the information from one of the second inputs to the output.
