  • Publication number: 20060220641
    Abstract: The device for sensing a magnetic field comprises a closed superconducting pick-up loop (1) having a path width (d) etched out of a single layer superconducting thin film and provided with a constriction (15) having a width (w) of narrow dimension smaller than the path width (d). The closed superconducting pick-up loop (1) constitutes a flux-to-field transformer (FFDT). At least one magnetoresistive element (2) is placed on top of or below the superconducting thin film, is isolated from the superconducting thin film by a thin insulating layer and is located so that an active part of the magnetoresistive element (2) is at the location of the constriction (15) and has a width equal to or less than the width of the constriction (15). The active part of the magnetoresistive element (2) is oriented so that the bias current in this active part is directed essentially along the constriction (15), orthogonally to the width of narrow dimension.

  • Publication number: 20060223582
    Abstract: A method and apparatus are provided for allowing a user to switch data containing user information from one device to another device, where the user is enabled to transfer data between devices in response to the user turning on or off the one device by either pressing a power or other suitable key on the device. In particular, the user is provided one or more options or prompts to select the manner data transfer of user information and the type of data transfer of user information to be switched from the one device to the another device. The manner of data transfer may include copying data to a SIM card, copying data to a memory card, switching data using a WLAN, switching data using Bluetooth, switching data using infrared, or some combination thereof; and the type of data transfer may include contacts, calendar, message information, other suitable personal information, or some combination thereof.

  • Publication number: 20060031038
    Abstract: The invention relates to a method and device by means of which an irrotational, sourceless vector field can be expressed by a number of physically reasonable basis vectors as small as possible in such a manner that the measured signals can be unambiguously divided into signals of the irrotational, sourceless vector field that are caused by an interesting object or external interferences, as well as into a signal caused by the nonideality of the measuring device, which signal is not included in the model of the signal space describing an irrotational, sourceless vector field. The invention is based on the combining of two very fundamental mathematical regularities and applying in the processing of signal vectors of a multi-channel measuring device that measures an irrotational, sourceless vector field: on the Maxell's equations of an irrotational, sourceless vector field, as well as on the convergence characteristics of series developments.

  • Publication number: 20050162249
    Abstract: The invention relates to a wall element for a magnetically shielded room and to a magnetically shielded room. The wall element comprises at least one first layer (1) which is formed of metal plate having a high electrical conductivity, and at least two layers, a second layer (2) and a third layer (3), which consist of metal plates having a high magnetic permeability. The layers (1, 2, 3) are superimposed one on top of another in surface contact with each other without any separating air gaps, so that each first layer (1) having a high electrical conductivity lies between each second (2) and third layers (3) having a high permeability substantially in surface contact with the second and third layers, the layers together forming a compact structure in which the product (?×?) of electrical conductivity (?) and permeability (?) is maximized so as to minimize the penetration depth of magnetic interference.

  • Patent number: 6538436
    Abstract: A method and apparatus is described for making multichannel signal measurements of weak signals in noisy environments, wherein the elimination of background interference signals from the multichannel signal measurement is performed. The method is based on an adaptive compensation technique in which the large interfering background signals are first recorded. By a statistical analysis of this multichannel measurement, independent components of the interference are determined. The apparatus is provided with compensator elements which are coupled to individual sensors for both collection and distribution of information on the interference signals during the measurement. In this way the output of a device can be made immune to the large amplitude interference components present in the device's environment. This reduces the dynamic range requirement for the data transport and storage systems.
