A method of monitoring mandibular movements whereby a permanent magnet is secured to the mandible and one or more fluxgate magnetometers are located relative to the permanent magnet so as to sense changes in magnetic field which result from mandibular movement. The outputs of the fluxgate magnetometers are linearized, if necessary, and then recorded to provide an indication of mandibular movement in one or more planes. The output from the magnetometers may be differentiated by associated electro...

A method of defining deviations from a desired position of pixel sites in an image recording matrix by defining the 3-D data of a planar or slightly curved surface. To the extent necessary the results are smoothed, and the measuring points, utilizing the 3-D data, are projected back the sensors of the image recording matrix for determining the difference between the two points projected onto the sensors and associated with a 3-D measuring point. After selectively shifting the surface relative to...

A method for measuring sleeping positions using a portable coordinate measuring machine is presented. The measured sleeping position information can be used to select or design a mattress which will result in a preferred sleeping position, whereby stresses on the individual's back and other muscles are minimized. The portable coordinate measuring machine comprising a multijointed manually positionable measuring arm for accurately and easily measuring a plurality of points or landmarks of an indi...

A measuring device for absolute measurement of positions is disclosed, which comprises a displacement sensor having a fixed element and a movable element which is relatively movable against the fixed element and being adapted to output a signal corresponding to the relative position of the movable element against the fixed element, demodulators for processing the output signal of the displacement sensor so as to obtain cyclic square signals for detecting at least two types of displacement of coa...

A measuring apparatus for measuring of positions or movements of two objects relative to one another with a force and/or moment sensor and a conversion spring element, with the force and/or moment sensor being elastically connected with one of the objects at least via the conversion spring element. A force and/or moment sensor with the measuring apparatus. A joystick with the measuring apparatus or the force and/or moment sensor.

The invention relates to a device for detecting movements and/or positions of an object with the aid of voltage pulses induced by the field of adjacent magnets (6, 7) in a coil (4). In order to generate a sufficiently strong signal also at small relative speeds between the magnets (6, 7) and the coil (4), the coil (4) encloses a spring (5) in which a quick fore-and-aft movement can be induced by the magnetic fields of the magnets (6, 7), the magnetic poles of the spring (5) being reversed during...

An operation member slidably supported on a base plate has opposed pawls which are spaced apart and project toward one another. A position control cam and an integral supplementary cam are rotatably supported on the base between the two pawls. The pawls are disposed on different planes so that a first pawl is engageable with the control cam and the second pawl is engageable with the supplementary cam. The operation member is spring biased in a direction to move the first pawl toward the position...

The invention comprises an information carrier on which the position of a measuring point (37, 41) may be determined using a mobile readout device, as well as an attendant method of determining a position wherein the information carrier features a surface onto which a visible primary information has been applied, in the manner of a book or a geographic map, wherein at least one machine-readable pattern has been printed on the surface, said pattern coding a position information, which upon bringi...
