  • Landmine excabator and neutralizer and related methods
    Patent number: 11199381
    Abstract: Clearing landmines is a dangerous activity and the danger is increased when trying to clear a landmine without triggering an explosion. An excavator for landmines is provided, which includes a first actuator that vertically moves a mounting plate. Two or more secondary actuators are mounted to the mounting plate, and each of the secondary actuators are able to extend and retract a tool. Each respective tool has drill bits or prongs for penetrating a ground surface. A neutralizer is also provided, and it includes: a robotic clamp to grip a landmine and to reposition the same; a cutting tool to cut an opening into the landmine; a steaming module to eject steam into the opening; and a catcher to collect melted explosive material that exits the landmine.
    Type: Grant

  • Ruggedized and high-brightness liquid crystal display and method of manufacture
    Patent number: 7764344
    Abstract: A ruggedized, high brightness, liquid crystal display (LCD) unit having a thin display panel, a front cover glass faceplate and an improved backlight assembly is disclosed. The faceplate is bonded to the panel using an improved process to minimize panel deformation and the backlight assembly is configured with an array of selectively spaced light emitting diodes (LED's) adapted to provide a uniform high brightness display with a minimal quantity of LED's.
