Patent number: 8027143Abstract: A micro-electromechanical device has a substrate (60), a movable element (15), a pair of electrodes (40) arranged on the substrate and on the movable element to move the movable element, and a controller (50) to supply the electrodes. To move the movable element to an intermediate position one or more pulses are applied during the movement, timed to compensate for under or over damping of the movement. This can reduce a settling delay. It can be applied to tunable RF capacitors. To control a decrease in the gap, a single pulse of a maximum supply level compensates for the inherent slowness of the device and over damping. To compensate for under damping, the pulses have a period corresponding to a resonant frequency, and comprise peaks and troughs above and below the final supply level, such that successive ones of the peaks and troughs are closer to the given supply level.Type: GrantFiled: October 10, 2006Date of Patent: September 27, 2011Assignee: EPCOS AGInventors: Theodoor Gertrudis Silvester Maria Rijks, Peter Gerard Steeneken

Patent number: 7903386Abstract: In a method for drive controlling a micro machine device including two electrodes opposing each other and a dielectric layer sandwiched therebetween, a control voltage in a rectangular waveform in which positive and negative polarities are alternately inverted is applied between the two electrodes. A current passing through the micro machine device due to the application of the control voltage are detected with respect to positive and negative sides, and parameters related to a capacitance of the micro machine device are acquired with respect to the positive and negative sides on the basis of the detected current. The control voltage is controlled so that the parameters acquired with respect to the positive and negative sides accord with each other. Thus, variation of the capacitance between the positive side and the negative side can be suppressed in switching drive of a variable capacitance device.Type: GrantFiled: February 28, 2008Date of Patent: March 8, 2011Assignee: Fujitsu LimitedInventors: Yu Yonezawa, Takeaki Shimanouchi, Naoyuki Mishima, Satoshi Ueda, Xiaoyu Mi, Masahiko Imai
