Abstract: A computer-implemented method for generating digital images encoded into a format readable by medical imaging apparatus defines, in a tridimensional continuous space, a tridimensional scene including a tridimensional continuous shape and an encompassing medium, the tridimensional shape being constituted from basic primary shapes by rotation, translation, overlapping or gathering of one or several basic primary shapes; discretizes the tridimensional scene obtained at the previous step into volume elements (voxels) using a weighting mechanism; segments the discretized tridimensional scene into voxels by creating bidimensional cross-sections of the tridimensional scene; and encodes the information describing the obtained bidimensional cross-sections of the tridimensional scene into a format readable by medical imaging apparatus.

Abstract: An alloy, in particular for an anti-friction coating, includes elements which form a matrix and at least a soft phase and/or a hard phase, which soft phase elements and/or hard phase elements form a solid solution or a bond with the matrix element. The soft phase and/or hard phase is dispersed in the matrix and the solid solution or bond is formed only in the region of the phase boundary of the matrix with the soft phase and/or with the hard phase.

Abstract: A method monitors whether the switching threshold of a switching sensor lies within a predefined tolerance region. An input signal is applied to the sensor's signal input, and a signal output emits a switch output signal that takes a first value when the input signal exceeds the switching threshold and, otherwise, takes a second value. A modulator generates a modulator signal used as an input signal that changes continuously or cyclically between an output value defining the upper limit and a smaller test value defining the lower limit of the tolerance region. The switch output signal pulses synchronously with the modulator signal between the first and second values when the switching threshold lies within the tolerance region and otherwise does not pulse. An evaluation device monitors the pulsation, an alarm signal being triggered when the switch output signal does not pulse for at least a predefined test period.

Abstract: A measurement setup to determine hitting parameters of a golf club includes a group of reflectors with at least two strip-shaped reflectors with retroreflective surfaces applied to the golf club shaft. The group of reflectors is attached to the club shaft with a detachable, yet tight clamp-connection. At least three retroreflective areas are arranged in a determined geometry at the club shaft and/or at the group of reflectors. At least one first reflective light barrier sends its beam at a right angle to the ideal swing path of the club head near the tee and/or the golf ball at the group of reflectors. During the penetration of the beam the three strip-shaped retroreflective surfaces elicit temporally staggered pulse-shaped signals that the receiver of the first reflective light barrier receives and which it transmits to the data acquisition device. A calibration setup is also provided.
