Transmission control arrangement, transmission, vehicle and method for transmission control

Abstract: There is provided an automatic or semiautomatic transmission for a motorized vehicle, comprising a guide (106;206) which is arranged to receive and control the position of at least two guided members (110,120;220,230), wherein the position of a guided member controls the mode of operation of a predetermined actuation device (260,250;260,350) e.g. gear selector, clutch plate or park brake etc. By moving said guide relative said guided members, the guided members are synchronously arranged at sequential pairs of positions (P1-P8), wherein said pairs of positions correspond to predetermined combinations of modes of operations of said actuation devices. In this way a synchronized and sequential series of movements of at least two actuation devices is provided, which may synchronize the movement of e.g. a gear selector and a clutch such that a change from a first gear via a neutral gear to a second gear is provided.

Verfahren und Vorrichtung zur Isolierung eines Radarfüllstandsmessgeräts

Abstract: Radarfullstandsmessgerat, das Mikrowellen zum Messen eines Fullstandes einer Oberflache eines Produktes in einem Tank verwendet und das umfasst: – eine Antenne zum Senden von Mikrowellen zu der Oberflache und zum Empfangen von durch die Oberflache reflektierten Mikrowellen, – einen Messschaltkreis, der die Antenne durch einen hohlen Wellenleiter speist, dadurch gekennzeichnet, dass das Radarfullstandsmessgerat weiterhin umfasst: – ein Antennenwellenleiterelement, das an einem Ende mit der Antenne verbindbar ist und das an seinem anderen Ende eine Offnung in einem Schnitt quer zu dem Wellenleiter aufweist, – eine dielektrische Barriere, die sich entlang des Schnittes uber die Offnung des Antennenwellenleiterelements zum nichtleitenden Trennen des Antennenwellenleiterelements von dem Messschaltkreis erstreckt, – wobei die dielektrische Barriere eine erste Seite aufweist, die in einer Richtung zu dem Antennenwellenleiterelement zu dem Wellenleiter zeigt, und – wobei die dielektrische Barriere eine zweite Seite aufweist, die in einer Richtung im Wesentlichen weg...

Garteur AD/AG-52: Surrogate-Based Global Optimization Methods in Preliminary Aerodynamic Design

Abstract: This work presents a summary of the results obtained during the activities developed within the GARTEUR AD/AG-52 group GARTEUR stands for “Group for Aeronautical Research and Technology in Europe” and is a multinational organization that performs high quality, collaborative, precompetitive research in the field of aeronautics to improve technological competence of the European Aerospace Industry The aim of the AG52 group was to make an evaluation and assessment of surrogate-based global optimization methods for aerodynamic shape design of aeronautical configurations The structure of the paper is as follows: Sect “Introduction” will introduce the state-of-the-art in surrogate-based optimization for aerodynamic design and Sect “Definition of Common Test Cases and Methods” will detail the test cases selected in the AG52 group Optimization results will be then showed in Sect “Optimization Results”, and conclusions will be provided in the last section

Method and apparatus for improving measurement precision in the area of travelling time differences of signals

Abstract: The invention provides a method and an apparatus for measuring the travelling time difference of a bandlimited signal that is transmitted from one emitter over at least two channels having different delays to at least two receivers. The emitter and the receivers may be stationary or moving. Basically the channels are undisturbed channels, but in general the channels may be disturbed by reflections of stationary or moving reflectors and multipath effects. The received signals are sampled and interpolated in a suitable way. The cross-correlation function of each two sampled and interpolated signals is calculated. The disturbing effects of movement, reflections and multipath effects are removed from the cross-correlation function, and a cleaned up cross-correlation function is provided that only represents the undisturbed channel. A continuous smooth curve is fitted to the maximum values of the cleaned up cross-correlation function. The maximum of the smooth curve provides an improved value for the travelling time difference.
