The present disclosure provides a system and a method for controlling a motion of a robot from a starting point to a target point within a bounded space with a floorplan including one or multiple obstacles. The method includes solving for an electric potential in a bounded virtual space formed by scaling the floorplan of the bounded space with the one or multiple obstacles and applying charge to at least one bound of the bounded virtual space while treating the scaled obstacles as metallic surfaces with a constant potential value, wherein the electric potential provides multiple equipotential curves within the bounded virtual space. The method further includes selecting an equipotential curve with a potential value different from a potential value of an obstacle equipotential curve, determining a motion path based on the selected equipotential curve, and controlling the motion of the robot based on the determined motion path.

System and method for controlling a motion of a robot

An electro-optic display comprising at least two separate layers of electro-optic material, with one of these layers being capable of displaying at least one optical state which cannot be displayed by the other layer. The display is driven by a single set of electrodes between which both layers are sandwiched, the two layers being controllable at least partially independently of one another. Another form of the invention uses three different types of particles within a single electrophoretic layer, with the three types of particles being arranged to shutter independently of one another.

A system for generating a G-code for controlling an operation of a laser-cutting machine to cut parts from a sheet of material, upon receiving cutting data specifying a cutting order of parts and a cutting order of edges of each part, tests the parts for potential distortions and generates a G-code to avoid the potential distortion. For testing a current part, the system detects a potential distortion when the final edge of the current part is adjacent to an edge of a previously cut part scheduled for cutting before the current part according to the cutting order of parts. The system modifies the cutting order to select the modified cutting order for which the final edge is not adjacent to any edge of any previously cut part.

System and method for detecting and correcting laser-cutting distortion

The present invention relates generally to a printing system, and more specifically to an ordering of color-forming layers in a direct thermal printing medium. The present invention provides a direct thermal print medium with an ordering of the color layers that improves the perceived image sharpness and color uniformity of prints.

A system and method depositing metal to form a three-dimensional (3D) part on a substrate. A wire is moved relative to a location on the substrate while a laser heats a proximal end of the wire at the location using a laser beam. The laser causes the wire and substrate to reach a melting point of the wire to fuse the wire at the location on the substrate. The wire can be preheated by passing a current through the wire.

Particle-based electro-optic displays are described that are both electrically and magnetically controllable. Global and local addressing may be provided. The global addressing may be providing by one or more electrodes of the display, and may be electrically activated. The local addressing may be provided by a writing implement, especially one capable of producing rotating electric fields.

Multi-color electro-optic displays

In one aspect of the invention there is disclosed a multicolor thermal imaging system wherein different heating elements on a thermal print head can print on different color-forming layers of a multicolor thermal imaging member in a single pass. The line-printing time is divided into portions, each of which is divided into a plurality of subintervals. All of the pulses within the portions have the same energy. In one embodiment, every pulse has the same amplitude and duration. Different colors are selected for printing during the different portions by varying the fraction of subintervals that contain pulses. This technique allows multiple colors to be printed using a thermal print head with a single strobe signal line. Pulsing patterns may be chosen to reduce the coincidence of pulses provided to multiple print head elements, thereby reducing the peak power requirements of the print head.

Print head pulsing techniques for multicolor printers

An optical disc is described that bears, on one surface, a plurality of color-forming layers that can form a multicolored image when heated in contact with a thermal print head. The color-forming composition comprises color-forming layers and thermally-insulating spacers and is designed such that warping of the optical disc in conditions of changing temperature and humidity is minimized. The compliance of the color-forming composition is such that intimate contact between the thermal print head and the printable surface of the disc can be maintained as one is translated relative to the other. Methods for assembling such an optical disc are provided.

A multicolor direct thermal imaging method wherein a multicolor image is formed in a thermal imaging member comprising at least first and second different image-forming compositions and a thermal printer for use in practicing the method. Heat is applied to at least the second image-forming composition while the first image-forming composition is at a first baseline temperature (T) to form an image in at least the second image-forming composition, and heat is applied to at least the first image-forming composition while it is at a second baseline temperature (T) to form an image in at least the first image-forming composition, wherein Tis different from T.
