20090009274 | SHORT-CIRCUIT INDICATOR FOR ELECTRICAL LINES FOR POWER DISTRIBUTION - A short-circuit indicator is provided for arrangement on an electrical line for electrical power distribution which includes a current transformer. The current transformer has an induction coil and an iron yoke for surrounding the electrical line to be monitored for a short-circuit current. The induction coil is seated on a base web of a U-shaped first yoke part. A second yoke part is connected in the form of a joint which can move between a closed position and an open position to one of two U-limbs of the first yoke part. The second yoke part forms a magnetic return path element for the first yoke part in the closed position. The first yoke part is split into two essentially L-shaped parts in the area of the base web to which the induction coil is fitted. | 01-08-2009 |
20100066473 | PROGRAMMABLE INDUCTOR - The present invention provides a programmable integrated inductor having a compact design, having a dual turn and a parallel programmable impedance. In particular, the impedance value of the programmable changes, like a variable, programmable, as its range may be set to an unlimited number of values. The invention, thus, provides a wider range of programmable values without compromising space, at a constant equivalent given inductor area. | 03-18-2010 |

20120262263 | INPUT DEVICE - An input device includes a first yoke; a substrate disposed on the first yoke; a coil disposed on the substrate; and a second yoke disposed above the coil and configured to be displaced downward by a force applied and thereby to change inductance of the coil. The input device is configured to output a signal corresponding to the amount of displacement of the second yoke. The substrate has an opening that communicates with a hollow of the coil, and the first yoke includes a step that is inserted into the opening of the substrate. | 10-18-2012 |
20130200968 | MULTI-LAYER-MULTI-TURN STRUCTURE FOR HIGH EFFICIENCY INDUCTORS - A multi-layer, multi-turn structure for an inductor having a plurality of conductor layers separated by layers of insulator is described. The inductor further comprises a connector electrically connected between the conductor layers. The structure of the inductor may comprise a cavity therewithin. The structure of the inductor constructed such that electrical resistance is reduced therewithin, thus increasing the efficiency of the inductor. The inductor is particularly useful at operating within the radio frequency range and greater. | 08-08-2013 |
20130200969 | MULTI-LAYER-MULTI-TURN STRUCTURE FOR TUNABLE HIGH EFFICIENCY INDUCTORS - A multi-layer, multi-turn structure for an inductor having a plurality of conductor layers separated by layers of insulator is described. The inductor further comprises a connector electrically connected between the conductor layers. The structure of the inductor may comprise a cavity therewithin. The structure of the inductor constructed such that electrical resistance is reduced therewithin, thus increasing the efficiency of the inductor. The inductor is particularly useful at operating within the radio frequency range and greater. | 08-08-2013 |
20140070911 | Liquid MEMS Magnetic Component - A liquid micro-electro-mechanical system (MEMS) magnetic component includes a board, a channel, one or more windings, a magnetizing-doped droplet, and a droplet activating module. The channel is implemented or embedding in one or more layers of the board and the one or more windings are proximally positioned to the channel. The magnetizing-doped droplet is contained in the channel and is modified by the droplet activating module based on the control signal. By modifying the magnetizing-doped droplet with respect to the one or more windings changes an electromagnetic property of the liquid MEMS magnetic component. | 03-13-2014 |
20140152410 | INTEGRATED TUNABLE INDUCTORS - An integrated inductor can be tunable via a control current which alters the magnetic flux density in a permeable magnetic material. The resulting inductor can be adjusted in-circuit, and may be suitable for applications such as dc-dc converters, RF circuits, or filters requiring operation at high frequencies and across wide bandwidths. | 06-05-2014 |
20140253272 | ELECTROSTATICALLY TUNABLE MAGNETOELECTRIC INDUCTORS WITH LARGE INDUCTANCE TUNABILITY - An electrostatically tunable magnetoelectric inductor including: a substrate; a piezoelectric layer; and a magnetoelectric structure comprising a first electrically conductive layer, a magnetic film layer, a second electrically conductive layer, and recesses formed so as to create at least one electrically conductive coil around the magnetic film layer; with a portion of the substrate removed so as to enhance deformation of the piezoelectric layer. Also disclosed is a method of making the same. This inductor displays a tunable inductance range of >5:1 while consuming less than 0.5 mJ of power in the process of tuning, does not require continual current to maintain tuning, and does not require complex mechanical components such as actuators or switches. | 09-11-2014 |
20140340183 | THIN FILM MAGNETIC ELEMENT - A magnetoresistive effect element includes a pair of first soft magnetic layers that are arranged opposite to each other so as to sandwich a magnetoresistive effect film; a second soft magnetic layer; and a coil that is windingly formed about the second soft magnetic layer. When a rear end region cross-sectional area of the first soft magnetic layers is defined as S1r and a tip end region cross-sectional area of the second soft magnetic layer is defined as S2f, S2f>S1r is established, and when a tip end width of the first soft magnetic layers is defined as W1f and a rear end width of the first soft magnetic layers is defined as W1r, W1r>W1f is established. | 11-20-2014 |
