摘要： A non-linear torsion hinge (12, 22) for a micro-mechanical device (10, 20) having a hinged movable element (11, 21). Each hinge (22) is comprised of two hinge strips (22a) spaced apart in the same plane, such that the axis of rotation of at least one of the hinge strips (22a) is different from the axis of rotation of the movable element (21). As a result, the hinge strip (22a) must elongate as it twists, thereby providing a greater restoring torque.

摘要： The present invention generally relates to a MEMS device having a plurality of cantilevers that are coupled together in an anchor region and/or by legs that are coupled in a center area of the cantilever. The legs ensure that each cantilever can move/release from above the RF electrode at the same voltage. The anchor region coupling matches the mechanical stiffness in all sections of the cantilever so that all of the cantilevers move together.

摘要： The current disclosure shows how to make a fast switching array of mirrors for projection displays. Because the mirror does not have a via in the middle connecting to the underlying spring support, there is an improved contrast ratio that results from not having light scatter off the legs or vias like existing technologies. Because there are no supporting contacts, the mirror can be made smaller making smaller pixels that can be used to make higher density displays. In addition, because there is not restoring force from any supporting spring support, the mirror stays in place facing one or other direction due to adhesion. This means there is no need to use a voltage to hold the mirror in position. This means that less power is required to run the display.
摘要翻译：目前的公开内容显示了如何制造用于投影显示器的反射镜的快速切换阵列。因为反射镜在连接到下面的弹簧支撑件的中间没有通孔，所以具有改善的对比度，这是由于不像现有技术那样从腿部或通孔没有光散射。因为没有支撑触点，镜子可以做得更小，从而可以用较小的像素来制作更高密度的显示器。另外，由于没有来自任何支撑弹簧支撑件的恢复力，因为粘附，反射镜保持在面向一个或另一个方向的位置。这意味着不需要使用电压将镜子保持在适当的位置。这意味着运行显示器需要较少的电力。

摘要： A micromirror array fabricated on a semiconductor substrate. The array is comprised of three operating layers. An addressing layer is fabricated on the substrate. A hinge layer is spaced above the addressing layer by an air gap. A mirror layer is spaced over the hinge layer by a second air gap. The hinge layer has a hinge under and attached to the mirror, the hinge permitting the mirror to tilt. The hinge layer further has spring tips under the mirror, which are attached to the addressing layer. These spring tips provide a stationary landing surface for the mirror.

摘要： A method of operating a micromechanical device. The device is in a first state. Data for the next state of the device is loaded onto the activation circuitry of the device, where the next state may be the same state the device is currently in, or a state different from the first state. The equilibrium of the device is shifted away from the next state, by making the data appear complementary to the true data for the next state. When the trapping field is removed or lowered, and a signal to start the transition is provided, the device moves to its new state and the trapping field is reapplied. The data can be made to look complementary by either loading the complements to the true data, or by reversing the polarity of the trapping field.

摘要： Embodiments disclosed herein generally solve a stiction problem in switching devices by using a series of pulses of force which take the switch from being strongly adhered to a landing electrode to the point where it is only weakly adhered. Once in the low adhesion state, the switch can then be pulled away from contact with a lower force provided by either the spring constant of the switch and/or the electrostatic forces resulting from low voltages applied to nearby electrodes.

摘要： A capacitively coupled microelectromechanical device and method of operation. The micromechanical device comprises: a semiconductor substrate; a member operable to deflect about a torsion axis to either of at least two states; and a switch driven for selectively connecting the member to a voltage signal. When a logic high signal is stored on the memory capacitor 308, the mirror transistor 310 is turned on, grounding the mirror structure 312. When a logic low signal is stored on the memory capacitor 308, the mirror transistor 310 is turned off, allowing the mirror to float electrically. Mirrors that are tied to a voltage potential, which typically are grounded, are affected by a reset pulse and rotate away from their landed position. When the mirrors have rotated to the opposite side, a bias signal is applied to hold the repositioned mirror in place in the opposite state. Mirrors that electrically are floating do not experience the forces generated by the reset voltage and remain in their previous state. The preceding abstract is submitted with the understanding that it only will be used to assist in determining, from a cursory inspection, the nature and gist of the technical disclosure as described in 37 C.F.R. § 1.72(b). In no case should this abstract be used for interpreting the scope of any patent claims.

摘要： An improved micromechanical device, particularly a micromirror device having improved electrostatic efficiency. A deflectable member comprised of a mirror 302 and an active hinge yoke 306 is suspended address 308 and landing electrodes 312 on a substrate 310 and above upper address electrodes supported above the substrate 310. The deflectable member is operable to rotate about a torsion hinge axis in response to an electrostatic force between the address electrodes and the deflectable member. The upper address electrodes have a stair stepped shape to narrow a gap between the deflectable member and the upper address electeodes. The gap is narrower near the axis of rotation 810 compared to away from the axis. The stair stepped shape is achieved by embedding a portion of an oxide layer 804 between a thin metal layer 806 making up the upper address electrodes 806, the active hinge yoke 306, and the torsion hinges, and a thick metal layer 808 making up the upper address electrodes 806 and the active hinge yoke 306.
