  • Method and an arrangement for scrollable cross point navigation in a user interface
    Patent number: 7293241
    Abstract: The invention relates to a method and an arrangement for scrollable cross point navigation on a user interface in order to select a feature by combining object fields. Bars, where at least one of them is scrollable, have object fields which overlap and combine each other when scrolled or put to a visible focus area in the user interface at the cross point of the bars. Object fields in the focus area select a feature connected to a combination of fields, which is chosen by a confirmation action.

  • Pressure sensitive device
    Patent number: 4233523
    Abstract: A pressure-sensitive device is proposed which includes an electrically conducting element in the form of a loop, a screen arranged outwardly of the loop, and a resiliently compressible, non-conducting material between the screen and element, the arrangement being such that, on the application of a loading to the screen, the electrical inductance of the loop is changed, such change being sensed by a reactance-dependent detecting circuit (DET) connected therewith.
