Abstract:
The invention relates to a method and a device for suppressing transmission noise from automatic transmissions, in particular for motor vehicles, the transmission having at least two alternating multi-disk clutches that control a power flow via a gearing mechanism through which oil flows to cool the clutches and to reduce wear and tear on them. To create a method and a device that are of simple design and that can operate without wear and tear, it is proposed that under defined operating conditions of the transmission, the throughput amount of oil is increased in such a way that a defined drag torque occurs at the multi-disk clutch that is opened.

Abstract:
The invention relates to curable compositions which comprise epoxy resins, amino hardeners, and a phosphonate of the formula I. Addition of phosphonate of the formula I can give cured epoxy resins which have not only improved flame retardants but also an increased glass transition temperature when comparison is made with the corresponding resins without said addition.
Abstract:
A vehicle accelerometer system comprises an accelerometer (290) for installation in a vehicle (500), a processor (210) for selection of accelerometer output data items for inclusion in an accelerometer output data set representative of measurements by the accelerometer (290) at a plurality of different vehicle locations, each accelerometer output data item being representative of a respective measurement by the accelerometer (290), and a storage device (230) for storing the accelerometer output data set, wherein the processor (210) is configured to process the accelerometer output data set to determine an orientation output representative of the orientation of the accelerometer (290) with respect to the vehicle (500).
Abstract:
The invention relates to an arrangement and a method for the recording and display of images of a scene and/or an object. They are suitable especially for the spatially perceived display of the recorded images. The problem of finding a new way of recording, with the least possible effort, images of real scenes or objects and subsequently displaying them three-dimensionally in two or more views by autostereoscopy is solved, according to the invention, in such a way that at least one main camera of a first camera type and at least one satellite camera of a second camera type are provided for the recording of images, with an image conversion device and a 3D image display device being arranged downstream of the cameras. The two camera types differ in at least one parameter; and a total of at least three cameras are provided. The invention also comprises a method for the transmission of 3D information.
Abstract:
Chimeric human-bovine parainfluenza viruses (PIVs) are infectious and attenuated in humans and other mammals and useful individually or in combination in vaccine formulations for eliciting an immune response to PIV or other pathogens. Also provided are isolated polynucleotide molecules and vectors incorporating a chimeric PIV genome or antigenome which includes a partial or complete human or bovine PIV “background” genome or antigenome combined or integrated with one or more heterologous gene(s) or genome segment(s) of a different PIV. Chimeric human-bovine PIV of the invention include a partial or complete “background” PIV genome or antigenome derived from or patterned after a human or bovine PIV virus combined with one or more heterologous gene(s) or genome segment(s) of a different pathogen, including different PIV virus to form the human-bovine chimeric PIV genome or antigenome.
Abstract:
A method is described for determining the charge state of a secondary intercalation cell having an anode, a cathode, a separator, and an electrolyte phase, which saturates the anode, the cathode, and the separator, in which the charge state is back-calculated on the basis of measured variables, which are measured on the intercalation cell, with the aid of an electrochemical simulation model. In the fundamental simulation model, physical-chemical properties in the anode and the cathode are each considered in simplified form as being homogeneously distributed in the anode and in the cathode and Butler-Volmer reaction kinetics are calculated in each case for the anode and for the cathode. The Butler-Volmer reaction kinetics are expanded on the anode side by a potential component (Φ2) in the electrolyte phase of the anode.
Abstract:
A lithographic apparatus includes a radiation system including a radiation source for the production of a radiation beam, and a contaminant trap arranged in a path of the radiation beam. The contaminant trap includes a plurality of foils or plates defining channels which are arranged substantially parallel to the direction of propagation of said radiation beam. The foils or plates are oriented substantially radially with respect to an optical axis of the radiation beam. The contaminant trap is provided with a gas injector which is configured to inject gas at least at two different positions directly into at least one of the channels of the contaminant trap.
Abstract:
The invention relates to a method for the stereoscopic display of a scene on a grid of picture elements (pixels), based on several views that are combined according to a combination rule to form a combination image. The combination image contains only selected parts or pixels of each view. Furthermore, propagation directions are fixed, which make it possible for a viewer to see in the combination image a different selection of views with his left eye than with his right eye, which results in a visual impression of space.Starting from an original view, in which each pixel contains bits of color information and depth information, the other views are generated, with exclusively such bits of color information being determined that belong to pixels of the views which are displayed in the combination image. The determination of the bits of color information is performed with the aid of a relief card Z(x,y).
Abstract:
A method and electrical system for controlling the power supply of an electric motor, in particular the electric motor of a vehicle that can be electrically driven, includes a control device that controls the power supply of the electric motor by an energy store. The energy store comprises a plurality of modules that are exposed to stress due to repeated charging and/or discharging and undergo an aging process as a result of said stress. In order to decouple the service life of the energy store from the service life of a vehicle, for example, the control device controls the charging and/or discharging of at least two modules differently such that said modules exhibit a stress difference so as to selectively reduce the aging process of the module being exposed to less stress.
