[Object] To realize a technique which enables a measurement error of a magnetic sensor to be obtained with higher accuracy. [Solution] There is provided an information processing apparatus including a fluctuation measuring unit configured to measure temporal fluctuation of a magnetic value measured by a magnetic sensor during movement of at least the magnetic sensor or information obtained based on the magnetic value, and a measurement error acquiring unit configured to obtain a measurement error of the magnetic sensor based on the fluctuation.
摘要:
Das auf einer Bodenplatte einen lawinenkundlichen Kompaß mit geometrisch spezifisch zur Ost - West - Richtung der lawinenkundlichen Kompaßrose angeordnete, geomorphologische Symbole umfassende lawinenkundliche Meßbesteck ermöglicht die Visualisierung von Textinformationen aus dem Lawinenlagebericht für die direkte Gefährdungsbeurteilung im Gelände. Im Lawinenlagebericht standardisiert genannten geomorphologischen Gefahrenstellen werden hierzu Symbole zugeordnet, die übereinander senkrecht zur Visierrichtung der lawinenkundlichen Kompaßrose angeordnet sind, und zwar so, daß die Symbole für die sogenannten schattseitigen Lagen mit dem Sektor Ost über Nord bis West und diejenigen für die sonnseitigen Lagen mit dem Sektor Ost über Süd bis West der Kompaßrose zusammenfallen. Die Symbole werden bei Nennung im Lawinenlagebericht markiert. Nun kann bei Anvisieren eines Hanges im Gelände über die von Nord nach Süd verlaufende Visierlinie durch Blick auf die Kompaßnadel und gegebenenfalls nach zusätzlicher Durchführung einer Neigungsmessung mit einem optionalen Neigungsmeßgerät schnell eine Aussage getroffen werden, ob es sich bei der anvisierten geomorphologischen Hangstelle um eine Gefahrenstelle handelt.

The use of magnetic field sensing to perform sophisticated command control and data input into a portable device (25) is disclosed. A magnetic field sensor is embedded or fixedly attached to a portable device to measure changes in the magnetic field strength and/or direction accompanying movement, motion or tilt of the device in one-, two- or three-dimensions when the portable device (25) is used to air-write or make gestures.
摘要:
An instrument comprising not only a compass (2), but also a laser (3) for the emission of a laser beam arranged to define, together with the laser beam, a direction to a point at a distance from the instrument, where the compass housing (5) and the laser (3) are mounted in an instrument housing (4) such that the laser is arranged to emit a laser beam parallel to the direction in which the compass is pointing. The invention is characterised in that the compass housing (5) is a separate unit that can be ejected from and inserted into a cavity (11) in the instrument housing (4) from one of its ends, in that opposing grooves (13) are arranged in the cavity (11) in order to position the compass housing (5) in the instrument housing, and in that a lock arrangement (14, 15) is present to lock the compass housing fixed in the instrument housing.

摘要:
There is provided a physical quantity data correcting device that can accurately and rapidly make a correction of physical quantity data even under an influence of a variation in an external environment or a disturbance by causing a computation control unit to appropriately control an approximate ellipsoid computing unit and/or a correction coefficient computing unit on the basis of a control parameter group. A physical quantity data acquiring unit (11) acquires physical quantity data output from a physical quantity detecting unit that detects physical quantities. A data selecting unit (11a) selects the acquired physical quantity data. An approximate ellipsoid computing unit (12) computes an approximate expression of an n-dimensional ellipsoid indicating a distribution shape obtained by distributing the selected physical quantity data in an n-axis (where n is an integer of two or greater) coordinate space. A correction coefficient computing unit (13) computes correction coefficients for correcting the computed n-dimensional ellipsoid to an n-dimensional sphere. A computation control unit (14) controls the approximate ellipsoid computing unit (12) and/or the correction coefficient computing unit (13) on the basis of a control parameter group (26). A correction data output unit (15) corrects the physical quantity data.
