Abstract: The use of pressure-sensitive selection tools in a graphical user interface is disclosed in which the amount of pressure during a selection operation may modify selection behavior. Upon receiving a selection input, the pressure applied is determined and the selection behavior modified. In some embodiments, the number of objects selected is increased when more pressure is applied and decreased when less pressure is applied.

Abstract: The use of pressure-sensitive controls is disclosed in which controls respond differently to different pressure applied by a stylus on a digitizer. Users interacting with displayed controls may modify the speed, increment, or other property of the control by pressing harder or softer. Devices that allow for the input of location and pressure information may use embodiments of the invention, including computers with pressure sensitive mice or digitizer tablets, PDAs, or tablet computers. Controls that may use pressure to augment their behavior include scrollbars, spinner controls, resize handles, buttons, drop down menus and so forth.

Abstract: The subject invention relates to systems and methods that facilitate display, selection, and management of context associated with execution of add-on instructions. The systems and methods track add-on instruction calls provide a user with call and data context, wherein the user can select a particular add-on instruction context from a plurality of contexts in order to observe values and/or edit parameters associated with the add-on instruction. The add-on instruction context can include information such as instances of data for particular lines of execution, the add-on instruction called, a caller of the instruction, a location of the instruction call, references to complex data types and objects, etc. The systems and methods further provide a technique for automatic routine selection based on the add-on instruction state information such that the add-on instruction executed corresponds to a current state.

Abstract: A tufting needle assembly for use with a tufting machine is disclosed that comprises a first gauge block or needle bar having a first series of tufting needles disposed thereon. The respective tufting needles are spaced from one another along a first longitudinal axis extending in the lengthwise direction of the gauge block. The tufting needle assembly further comprises a second series of spaced tufting needles extending along a second longitudinal axis spaced parallel to the first longitudinal axis.

Abstract: In computerized diagnostic X-ray apparatus data can be provided for a plurality of parallel sectional representations of the body of a patient. If, however, data are required for planes at different orientations in the body it has been usual to realign the body in relation to the apparatus and repeat the examination. It is now proposed to assemble data for inclined planes through the body by reassembly of data for the sections actually examined. The method of achieving this is described, together with a suitable apparatus for the purpose.

Abstract: In a computerized axial tomographic apparatus it is proposed to use, as radiation detectors, alkali halide scintillator crystals cooperating with photodiodes to measure the light output therefrom, or else photodiodes directly sensitive to the radiation passed through the patient. For advantageous operation, especially in regard to drift and rapidity of operation, it is proposed to use the photodiodes photovoltaically and in the so-called "current mode".
