  • Devices, Methods, and Graphical User Interfaces for Navigating Between User Interfaces and Interacting with Control Objects
    Publication number: 20240143162
    Abstract: An electronic device responds to a user input that includes a movement detected while displaying a user interface object at a first position relative to a first user interface of a first application. If the user input is directed to a location that corresponds to the first user interface object at a start of the movement, the electronic device moves a respective representation of the first user interface in accordance with the movement, relative to a background located behind the first user interface and remaining visible during the movement. If the user input is directed to a portion of the first user interface that is away from the location that corresponds the first user interface object, at the start of the movement, the electronic device performs an operation within the first user interface without moving the respective representation of the first user interface relative to the background.

  • NOVEL 10,10'-SUBSTITUTED-9,9'-BIACRIDINE LUMINESCENT MOLECULES AND THEIR PREPARATION
    Publication number: 20020034828
    Abstract: Novel symmetrical and asymmetrical 10,10′-substituted-9,9′-biacridines and the synthesis of such symmetrical and asymmetrical 10,10′-substituted-9,9′-biacridine molecules and their derivatives is disclosed. These molecules are shown to produce light by chemiluminescence in the presence of signal solutions. These symmetrical or asymmetrical 10,10′-substituted-9,9′-biacridines are used alone or attached to haptens or macromolecules and are utilized as labels in the preparation of chemiluminescent, homogeneous or heterogeneous assays. They are also used in conjunction with other chemiluminescent label molecules to produce multiple analyte chemiluminescent assays.
