  • Patent number: 9472347
    Abstract: A variable vacuum capacitor includes two pairs of electrodes ganged together in series such that no moving parts are required to connect electrically to any static pans. Two sets, or gangs, of movable electrodes are connected mechanically and electrically together such that they move together and such that they require no electrical connection to any other part of the device. The ganged arrangement means that the device can be constructed with a smaller diameter, but without significantly increasing the overall length of the device.

  • Patent number: 8804973
    Abstract: In an example signal clustering apparatus, a feature of a signal is divided into segments. A first feature vector of each segment is calculated, the first feature vector having has a plurality of elements corresponding to each reference model. A value of an element attenuates when a feature of the segment shifts from a center of a distribution of the reference model corresponding to the element. A similarity between two reference models is calculated. A second feature vector of each segment is calculated, the second feature vector having a plurality of elements corresponding to each reference model. A value of an element is a weighted sum and segments of second feature vectors of which the plurality of elements are similar values are clustered to one class.

  • Patent number: 8254081
    Abstract: In a laminated ceramic electronic component in which, by directly carrying out a plating process on an outer surface of a component main body, an external electrode is formed thereon, an attempt is made to improve the adhesion strength between a plated film forming the external electrode and the component main body. A brazing material containing Ti is applied to at least one portion of a surface on which external electrodes of a component main body is formed, and by baking this brazing material, a metal layer containing Ti is formed. Moreover, the external electrodes are formed by a plating process so as to coat at least the metal layer, and a heating process is then carried out so as to cause counter diffusion between the metal layer and the plated film that is to form the external electrodes.

  • Patent number: 8031174
    Abstract: A multi-layer cover for an electronic device having one or more of a sensor panel, a proximity sensor, an ambient light sensor, and a display device can include an outer hardcoat, a structural layer, an IR transmissive ink layer, a mask layer, and a backside hardcoat. The backside hardcoat can reduce cover warpage, enable full surface lamination of the cover to the sensor panel, prevent bubbles from forming in transparent windows in the cover, enable a wider range of functional inks to be applied in various layering orders to allow certain types of light to pass through while blocking others, and hide the sensors to provide a seamless, uncluttered visual appearance.

  • Patent number: 8027143
    Abstract: 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.

  • Patent number: 7903386
    Abstract: 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.

  • Patent number: 5771148
    Abstract: A voltage variable capacitor (VVC) is made by placing an intercalation compound between two electrodes of a capacitor. The VVC has a reservoir of an intercalant in proximity with the intercalation compound. The two materials are chosen from those known to exhibit the intercalation reaction. The extent of the intercalation reaction is controlled by applying a voltage to the intercalant reservoir and the intercalation compound. A variable capacitor is created by applying a signal to the device and appropriately controlling the .di-elect cons. of the device by using the input control voltages.

  • Patent number: 4173032
    Abstract: A binary capacitor consists of a piston having a metallized band on its periphery. The piston is movable between first and second positions within a cylinder which carries two spaced metallized bands. One of the positions of the piston defines a position of maximum capacitance, i.e. where the band on the piston overlaps both of the cylinder bands. The second position of the piston defines a position of minimum capacitance; i.e. where the piston band clears at least one of the cylinder bands. The piston is latched in its stable minimum and maximum states by fixed permanent magnets located at the ends of the piston in combination with soft iron slugs at the ends of the cylinder. The piston is moved by appropriately energizing electromagnetic coils wound over the soft iron slugs on the cylinder.
