  • Patent number: 11399909
    Abstract: A LUS robotic surgical system is trainable by a surgeon to automatically move a LUS probe in a desired fashion upon command so that the surgeon does not have to do so manually during a minimally invasive surgical procedure. A sequence of 2D ultrasound image slices captured by the LUS probe according to stored instructions are processable into a 3D ultrasound computer model of an anatomic structure, which may be displayed as a 3D or 2D overlay to a camera view or in a PIP as selected by the surgeon or programmed to assist the surgeon in inspecting an anatomic structure for abnormalities. Virtual fixtures are definable so as to assist the surgeon in accurately guiding a tool to a target on the displayed ultrasound image.

  • Patent number: 8798510
    Abstract: When reading calibration chevrons during mark-on-belt (MOB) sensor timing calibration, cyan portions or legs of printed chevrons are detected in order to determine a timing window offset adjustment. Depending on which of the six cyan legs on the left side of the chevrons are detected, a determination can be made regarding whether the window needs to be started earlier or later. If only the first two cyan legs on the left side of the chevron are detected, then the MOB sensor timing window is beginning (and ending) too early and an appropriate adjustment can be made to cause the timing window to initiate later. If only the last two cyan legs on the left side of the chevron are detected, then the MOB sensor timing window is beginning (and ending) too late, and appropriate adjustment can be made to cause the timing window to initiate earlier.

  • Publication number: 20140160221
    Abstract: The present invention relates to a method of marking a substrate that comprises a color forming material, comprising the steps of: activating a region of the substrate so as to transform it from an inactive, low reactive state to an active, high reactive state; irradiating a part of the activated region with an initial color changing radiation to effect an initial color change to a first color; and irradiating a part of the substrate that has been changed to the first color with a high power density beam of visible electromagnetic radiation to effect a further color change of the irradiated region to a second color.

  • Publication number: 20140160220
    Abstract: What is described is a method for producing a sign, pattern, symbol and/or image (8) on a substrate (2) with colour bodies arranged on said substrate, said colour bodies losing the colour effect under the influence of a laser (23) and consisting of dyes or pigments contained in capsules (1), wherein different colour bodies (1) having at least three different colour effects are arranged on or in the substrate (2). The invention is characterised by the following method steps: (a) producing a colour chart (14), in which the individual colour effect of individual colour bodies (1) formed from dyes or pigment particles is contained as a function of the spatial coordinates thereof on or in the substrate (2); (b) spatially resolved radiation, which open the colour effect of colour bodies (1) just of individual capsules and release these dyes, by means of an excitation beam of a laser (23) at a single frequency on the basis of the colour chart (14) in order to produce a resultant colour effect.

    Abstract: The present invention relates to a color printer and particularly to a color printer reducing power consumption and complying with international criteria ensuring sustained earth environment. In a color printer having multiple optical writing heads for individual recording colors, the activated periods of individual color recording heads are set to different periods and one writing period of individual recording heads is divided into multiple periods, video data for recording one dot line are divided into multiple blocks in the main scan direction, and the divided video data are used for emission at different times in the sub-scan direction, whereby a smaller number of optical writing elements are simultaneously driven for emission and the peak power consumption of the entire apparatus is reduced.
