  • Patent number: 9354706
    Abstract: An example of an information processing apparatus calculates a first position using imaging information based on an image captured by an imaging device. The information processing apparatus calculates a second position using a detection result of a sensor. The information processing apparatus repeatedly determines whether or not a predetermined condition is satisfied, the predetermined condition including a condition regarding a relationship between the first position and the second position. A designated position on a predetermined plane is calculated using the first position and/or the second position. In a satisfaction period after the predetermined condition has been satisfied, the information processing apparatus calculates the designated position by making an influence of the second position relatively great as compared to an unsatisfaction period before the predetermined condition is satisfied.

  • Patent number: 9255851
    Abstract: A method for identifying the location of a binding zone between a stuck tubular and a borehole includes the steps of passing a demagnetizing stress sensor through the tubular on a baseline magnetization pass to magnetize the tubular. Next, the demagnetizing stress sensor measures a baseline magnetization of the tubular. Once the baseline magnetization has been established, the method continues by applying a stress to the tubular and passing the demagnetizing stress sensor through the tubular on a scanning pass while the tubular is stressed. The demagnetizing stress sensor then measures a stress-induced magnetization of the tubular. The method concludes by comparing the baseline magnetization of the tubular against the stress-induced magnetization of the tubular. Notably, in preferred embodiments, the method includes the magnetization of the tubular in a substantially radial direction and the stresses are applied in vectors perpendicular to the radial magnetization of the tubular.

  • Patent number: 8450997
    Abstract: Magnetic tracking systems and methods for determining the position and orientation of a remote object. A magnetic tracking system includes a stationary transmitter for establishing a reference coordinate system, and at least one receiver. The remote object is attached to, mounted on, or otherwise coupled to the receiver. The transmitter can include a set of three mutually perpendicular coils having a common center point, or a set of three coplanar coils with separate centers. The receiver can include a set of three orthogonal coils. The position and orientation of the receiver and the remote object coupled thereto is determined by measuring the nine mutual inductances between the three transmitter coils and the three receiver coils. The magnetic tracking system provides reduced power consumption, increased efficiency, digital compensation for component variation, automatic self-calibration, automatic synchronization with no connections between transmitter and receiver, and rapid low-cost implementation.

  • Patent number: 8432160
    Abstract: A method for estimating the value of the weight of the contents of the oscillating assembly of an electronically controlled household appliance is provided. The oscillating assembly is connected to a frame by a suspension system having a damper. The damper includes at least two mechanical elements adapted to move reciprocally, a magnetic element which detects reciprocal motion, depending upon the distance between the two elements, the magnetic sensor generates an electrical signal. A reading of an initial value of an electric parameter, is taken when the oscillating assembly is empty. A mathematical function is identified on the basis of the initial value and of a plurality of predetermined parameters, which relate the electrical parameter to the weight of the contents. A second reading is taken when contents have been loaded in, and the value of the weight of the contents is estimated by using the mathematical function and electric parameters.

  • Patent number: 8198889
    Abstract: A magnetic sensor for an elevating motor, and more particularly to a magnetic sensor whose magnetic induction elements are sealed within a magnetically non-permeable minor sleeve. Meanwhile, a signal transmission line is extended therefrom. In addition, the minor sleeve and the magnetic induction elements are disposed within a gear box of the elevating motor. Since the magnetic sensor in accordance with the invention is designed in a built-in type, it is not easily affected and damaged by the external environment. As a result, the service life may be prolonged. Moreover, it is modularized for a compact structure and a practical installation. In addition, it approaches more to the rotational and magnetic pole, thereby enhancing the measuring accuracy.

  • Patent number: 8148976
    Abstract: The invention relates to a method and arrangement for the contactless determination of conductivity-influencing properties and their spatial distribution over the entire cross section of an electrically conductive substance moving in a primary magnetic field (B). The substance may be a liquid or a solid. A simultaneous measurement of a number of mechanical state parameters of the magnetic system is performed (three-dimensional components of the force and the torque), said parameters being variable by the effect of a secondary field on the magnetic system, the secondary field being produced on the basis of eddy currents induced in the substance by the primary field (B). To determine the spatial distribution of the property that is sought, the primary field is changed in intensity or form a number of times and a measurement of the state parameters is carried out for each change.
