Abstract: An electronic device capable of carrying out a plurality of commands, which are symbolized by a plurality of icons displayed on a touch screen so as to allow a user to select a command by contacting the screen at the icon with a pen, or other object. If the contact is brief, the selected command is carried out. If the contact is longer than a predetermined time, a message associated with the command is provided. In the latter case, if the user still wants the selected command to be carried out, the user removes the pen off the screen directly from the icon. Otherwise, the user moves the pen out of the icon area. The message is then ended. If the user moves the pen to another icon, a different message is provided. The message can be provided in a text form or an audible form.

Abstract: The invention relates to a method for automatic inspection of the surface 20 of a moving object, in which a region on the object's surface is illuminated from at least two different illumination directions 13-15. The object's illuminated surface region is imaged with a camera to provide image information for analysis. The light sources in the different illumination directions 13-15 are pulsed to illuminate the object's surface region at different times, the pulsing frequency being >1 kHz The object's illuminated surface region is imaged as lines with a line scan camera 21 in sync with the above pulsing.

Abstract: In a method an an apparatus for automatic inspection of moving surfaces using at least three different illumination/observation channels, the surface to be inspected under a bright field condition is illuminated by a first beam of light from a first light source. The light of the first beam of light reemitted from the surface is received by a light sensitive sensor device to obtain a first signal. Then, the surface is illuminated under a dark field condition by a second beam of light and by a third beam of light from a second and a third light source, respectively, the first, second and third beams of light having different characteristics. The light of the second beam of light and the light of the third beam of light, respectively, reemitted from the surface are received by the light sensitive sensor device to obtain a second signal and a third signal. Finally, a physical property of the surface is derived from the first, second and third signals.
