Abstract: On décrit une première mosaïque de capteurs linéaires (42) qui produit, à un premier temps de latence, une première image d'un segment d'un objet (12) qui se déplace devant les capteurs à une vitesse variable. L'image et le temps de latence sont stockés dans une mémoire tampon. A mesure que l'objet continue de se déplacer devant les capteurs, plusieurs images successives du segment vues par la première mosaïque de capteurs sont stockées dans la mémoire tampon en même temps que leur temps de latence respectif. Une deuxième mosaïque de capteurs linéaires (44), disposée à une distance d de la première mosaïque produit, à un deuxième temps de latence, une deuxième image d'un autre segment de l'objet en déplacement. Cette deuxième image est comparée avec les premières images stockées pour déterminer laquelle desdites premières images stockées s'approche le plus de la deuxième image. Ainsi, la vitesse de l'objet S peut être estimée en tant que fonction correctement pondérée de d/(tj-tm) [c-à-d, S  PROPORTIONAL  d/(tj-tm)], tj étant le temps de latence d'une image sélectionnée dans la deuxième série d'images, et tm étant le temps de latence de la première image qui s'approche le plus de la deuxième image sélectionnée. En réglant continuellement la vitesse de l'objet de cette manière, il est possible de sélectionner et transférer dans une mémoire tampon d'images ceux des segments d'images qui, ensemble, présentent de l'objet la meilleure qualité d'image, indépendamment de la vitesse de déplacement de l'objet le long du capteur et sans qu'il soit nécessaire d'utiliser des moteurs pas-à-pas, des codeurs de mouvement mécaniques, etc., encombrants et chers.

Abstract: A method and apparatus for providing welding type power is disclosed. The power source is capable of receiving any input voltage over a wide range of input voltages and includes an input rectifier that rectifies the ac input into a dc signal. A dc voltage stage converts the dc signal to a desired dc voltage and an inverter inverts the dc signal into a second ac signal. An output transformer receives the second ac signal and provides a third ac signal that has a current magnitude suitable for welding, cutting or induction heating. The welding type current may be rectified and smoothed by an output inductor and an output rectifier. A controller provides control signals to the inverter and a controller power supply can also receive a range of input voltages and provide a control power signal to the controller, and a voltage independent of the input voltage.

Abstract: Electromagnetic field mapping is accelerated by acquiring data from the surface bounding a volume of interest and solving the boundary value problem (BVP) using Green's function. Instead of measuring electromagnetic field components on a step-by-step basis at each point within a region of interest, only a component of the field, preferably the normal component, is measured on the surface bounding the volume. The use of surface data acquisition, a solution to the BVP using Green's function, and optional error correction based on the treatment of errors as virtual sources, combine to produce a process of defining of the electromagnetic field within the volume that reduces to a few minutes what presently takes days or longer. Data acquisition may be carried out either by moving sensors along the surface or, preferably, by fixing the position of several single axis on the surface bounding the volume.
