Abstract: The present exemplary embodiment relates to an improved flexible display system. One form of the display may use various types of switchable materials contained in micro cells formed from a fabric or mesh material. These cells may serve as a spacer between two opposing electrode sheets and may be individually sealed to the electrode sheets on each face. Moreover, the fabric may, in some forms, be implemented as an electrical grid for addressing the micro cells.

Abstract: A MEMS system including a fixed electrode and a suspended moveable electrode that is controllable over a wide range of motion. In traditional systems where an fixed electrode is positioned under the moveable electrode, the range of motion is limited because the support structure supporting the moveable electrode becomes unstable when the moveable electrode moves too close to the fixed electrode. By repositioning the fixed electrode from being directly underneath the moving electrode, a much wider range of controllable motion is achievable. Wide ranges of controllable motion are particularly important in optical switching applications.

Abstract: The present invention is directed to syringes that have needles that retract after an injection to provide safe syringes which reduce the possibility of a sharps injury through retraction of the needle after use into the barrel of the syringe. The syringe includes a barrel, a needle assembly positioned in the hollow body, a fluid retention system positioned in the hollow body, and a plunger assembly that moves in the hollow body. A fluid retention system retains in the syringe any fluid remaining in the needle after the plunger assembly approaches tha distal end of the hollow body. The fluid retention system includes a variable volume vacuum cavity in fluid communication with the needle passage, the vaccum cavity expanding prior to retraction of the needle assembly and providing a pressure drop in the needle, tending to draw into the hollow body any fluid remaining in the needle.
