Patent EP-0430094-A1 (EP)
Inventor: STURGILL MICHAEL R
IPC: A61B8/06
Filed: 1990-11-23
Abstract: A system for improving the flow estimation sensitivity of an ultrasonic Doppler flow imaging system includes an ultrasonic wave transmitter and receiver for sequentially transmitting ultrasonic waves toward and into a living body and for receiving the reflected Doppler-shifted echo signals. A series of echo signals received from each of a number of points within the body are processed in a velocity estimator, using maximum entropy techniques, to produce an output signal representative of an estimated velocity of the flow at each of said points within the body. The processing means detects the series of echo signals for each point and calculates an average power spectrum based on the amplitude-versus-frequency distribution of the series of received echo signals. The power spectrum is calculated by fitting a first order polynomial to the series of echo signals, although higher order polynomials can be used. A peak center frequency shift associated with the data detected for each point is derived from the power spectrum. The resulting peak center frequency shift information is then processed to produce a velocity estimate for each of the points at which velocity is being measured, and the resulting velocity estimate information is then processed further for imaging in a two-dimensional Doppler color flow imaging display.

Abstract: On fait varier au moins un paramètre d'usinage d'une machine découpant par électroérosion avec un fil-électrode, selon une trajectoire prédéterminée, lorsque le fil-électrode atteint le sommet d'un angle ou aborde un arc. Le procédé comporte les étapes suivantes : 1) calcul des endroits de la trajectoire où doivent être enclenchées ces variations; 2) arrêt du mouvement relatif entre le fil-électrode et la pièce à usiner lorsque le fil atteint l'un de ces endroits; 3) variation graduelle et par paliers du paramètre jusqu'à une valeur finale désignée ou jusqu'à ce qu'un nombre prédéterminé de paliers ait été effectué ou pendant un laps de temps donné; 4) reprise du mouvement relatif fil-pièce, avec la nouvelle valeur du paramètre sur une distance prédéterminée par le calcul, et 5) variation du paramètre en sens inverse afin de le ramener à sa valeur initiale. Les durées des paliers sont prédéterminées ou correspondent à la découpe de longueurs prédéterminées le long de la trajectoire.

Abstract: A system for providing low insertion force electrical interconnections between high density contacts for use in interconnecting circuit packages. A housing has disposed therein one or more pre-buckled beam connectors. Each connector has a resilient insulating strip carrying a plurality of buckling beams electrically isolated from each other. The beams are aligned on the plane defining the strip in parallel with ends extending away from the strip edges in opposing directions. Means are provided for deforming the strip within the housing prior to effecting desired interconnections whereby the beams are pre-buckled. Upon urging contacts into proximity with the beam ends, the buckling force is released causing each beam's ends to be urged away from the strip into engagement with respective contacts, thereby effecting desired interconnection between contacts and through one or more beams.

Abstract: A mower includes a first chassis attachable to a tractor for movement in a work direction, a second chassis having first and second structures connected at a joint extending perpendicular to the work direction, and connecting rods, each having respective ends pivotally connected to the first chassis and to the second structure of the second chassis so as to form with the first and second chassis an upwardly deformable quadrilateral deformable such that the work elements may move to adapt to ground contours. A release safety device normally prevents pivoting of the first structure about the joint but permits pivoting of the first structure about the joint axis when the first structure or the working elements hooks an obstacle during movement of the mower in the work direction. This limits forces applied to the mower.

On rend la fréquence de la tension transmise au convertisseur de fréquence proportionnelle à la tension d'alimentation. Après l'écoulement d'une période de temps, le contenu du compteur change d'une quantité proportionnelle à l'énergie active consommée pendant cette période.

Abstract: The under-voltage release device has an electromagnet with a magnet winding (3), a core (10) and an armature (20) and a release device (50) which is capable of a release movement. In the condition when it is ready to release, the armature is located in an attracted position on the core and in this case is spring-loaded in the release direction but is prevented from being released from the core by the magnetic attraction force generated by the electromagnet. In this condition, the release device is also spring-loaded, but the release movement is prevented by the attracted armature. The electromagnet is a DC magnet. A rectifier is provided in order to rectify the current flowing through the magnet winding. In addition, mechanical aids are provided in order to position the armature in the attracted position. The release device is latched in a self-releasing manner in the condition where it is ready to release. The latch is released when the armature is released.
