| 20090129656 | VOTING IN MAMMOGRAPHY PROCESSING - Methods and systems are disclosed to aid in the detection of areas of interest in an image. Multiple image recognition processes analyze the image and identify areas of interest. The identified areas of interest are compared to determine confidence values for each identified area of interest using a voting process. The confidence values may be used in determining areas of increased interest which are highlighted on the image. In embodiments, identified areas of interest meeting a certain threshold requirement are selected as areas of increased interest. In other embodiments, new areas of increased interest are created by combining areas of interest. Embodiments of the disclosed methods and system may be used to aid in the detection of cancer in mammogram images. | 05-21-2009 |
| 20090132916 | USER INTERFACE FOR ADJUSTING THRESHOLDS AND PRESENTING MAMMOGRAPHY PROCESSING RESULTS - Methods for displaying various user interfaces are disclosed for use in conjunction with image analysis software. User interfaces disclosed identify areas of interest on an analyzed image. The identified areas of interest are correlated with a confidence value displayed on the image as well, giving the user an idea of the likelihood that an identified area of interest corresponds to an actual area of interest on the image. The disclosed user interfaces may also provide a tool to users which allow the user to set and reset a threshold value or values used in analyzing the image. The displayed areas of interest may change due to the user setting a custom threshold value. | 05-21-2009 |
| 20090192810 | FRAUD DETECTION SYSTEM & METHOD - Methods and systems are disclosed for combining the results from multiple fraud detection devices into a single, ordered list of suspect items. The confidence value for each suspect item identified by each fraud detection process may be calculated. Calculated confidence values may be refined by resealing the confidence value. The confidence value of items from multiple lists may then be further refined using a voting process. Use of a voting process takes into account the determinations of each of the fraud detection processes in order to calculate or refine the confidence values associated with each suspect item. After conducting the voting process, the suspect items may be combined into a single suspect list. The new suspect list may be ordered by confidence values. Additionally, the expected loss of each item may be calculated for each suspect item. Suspect lists may also be ordered according to expected loss. | 07-30-2009 |

| 20080246373 | GENERATING ELECTROMAGNETIC FORCES - An electromagnetic actuator includes a body having a rotational axis, a first pole adjacent an end facing surface of the body, and a second pole adjacent a lateral facing surface of the body. The poles are adapted to communicate magnetic flux with the body. The body, the first pole, and the second pole define an axial magnetic control circuit. The actuator includes a plurality of radial poles adjacent the lateral facing surface of the body and adapted to communicate magnetic flux with the body. The body and the plurality of radial poles define a plurality of radial magnetic control circuits. The plurality of radial poles are adapted to communicate magnetic fluxes with the body and at least one of the first pole or the second pole. The body, the plurality of radial poles, and at least one of the first pole or the second pole define a magnetic bias circuit. | 10-09-2008 |
| 20090201111 | GENERATING ELECTROMAGNETIC FORCES WITH FLUX FEEDBACK CONTROL - An electromagnetic actuator with flux feedback control includes two poles located on opposite sides of a soft-magnetic target. A bias flux is introduced that flows into both poles. Magnetic circuitry may be designed so that the total bias flux is independent or substantially independent of a position of the target with respect to the poles or the control flux. The electromagnetic actuator also includes flux sensors introduced into each gap between the poles and the target. The electromagnetic actuator further includes an actuator control circuit to command the current in the control coil to bring a difference between the readings of the two flux sensors to a targeted level. In some aspects, the force exerted on the actuator target in this arrangement may be proportional to the command signal regardless of the position of the actuator target, MMF drop in the soft-magnetic parts of the magnetic circuit, or the frequency. | 08-13-2009 |
| 20100090556 | HIGH-ASPECT RATIO HOMOPOLAR MAGNETIC ACTUATOR - A homopolar magnetic actuator is configured to exert controllable radial forces on a body adapted to rotate around an axis. The actuator comprises at least three radial magnetic pole assemblies distributed at some distances from each other along the axis, each including a plurality of poles adjacent to an actuator target on the body. Permanent magnets are used to induce bias magnetic fluxes in the assemblies with polarities alternating from assembly to assembly but remaining the same around the rotational axis. Having several small bias fluxes distributed between several pole assemblies instead of a large single bias flux facilitates designing an actuator with a high aspect ratio. A control coil around each pole can induce a control magnetic flux in the poles. These control fluxes affect magnetic flux distribution around the actuator target, resulting in magnetic forces exerted on the target. | 04-15-2010 |
| 20100117627 | MEASURING LINEAR VELOCITY - An apparatus for measuring linear velocity of a movable element relative to a stationary element includes a magnetic element fixed in relation to the stationary element. A soft-magnetic yoke is fixed in relation to the movable element to move with the movable element and is in non-contact relation with the magnetic element. A yoke pole is positioned proximate to the magnetic element and spaced therefrom by an air gap. The pole is magnetically coupled to the magnetic element so that a magnetic flux is generated in the air gap substantially orthogonal to the axis of motion. A conductive coil is coiled around a coil axis and is fixed in relation to the stationary element with the coil axis substantially parallel to the axis of movement. The coil is in non-contact relation with the yoke and resides between the magnetic element and the pole of the yoke in the magnetic flux. | 05-13-2010 |
| 20100301840 | MEASURING THE POSITION OF AN OBJECT - Noncontact measuring of positions of objects is achieved through measurements of parameters characterized by the distribution of an AC magnetic flux in the air gap between stationary and moveable portions defining a sensor magnetic circuit. | 12-02-2010 |
| 20110101905 | GENERATING ELECTROMAGNETIC FORCES IN LARGE AIR GAPS - An electromagnetic actuator generates electromagnetic forces across large radial gaps to support a body. The actuator has an actuator target having a rotational axis, and a target magnetic element arranged circumferentially around the rotational axis that has inner and outer magnetic poles. A cylindrical soft-magnetic target pole is magnetically coupled to the outer cylindrical magnetic pole of the target magnetic element. An actuator base includes radial poles arranged circumferentially around and radially spaced apart from the cylindrical soft-magnetic target pole. The radial poles and the cylindrical soft-magnetic target pole are magnetically coupled and define a plurality of magnetic control circuits. Control coils around the radial poles are configured to produce magnetic fluxes in the magnetic control circuits. The target magnetic element, the cylindrical soft-magnetic target pole, and the radial poles are magnetically coupled and define a magnetic bias circuit, the magnetic element producing magnetic flux in the magnetic bias circuit. | 05-05-2011 |
