摘要:
A system for automatic adjustment of at least one element provided with at least one actuator and provided inside or outside a vehicular cabin is provided. The system includes at least one microphone array for detecting utterances of at least one speaker and for obtaining microphone signals corresponding to the utterances. A localization detector is configured to determine the position of the speaker on the basis of the microphone signals. The localization detector outputs a localization signal to a controller. The controller is configured to receive the localization signal and automatically controls the actuator of the element on the basis of the localization signal. A method for automatically adjusting at least one element provided with at least one actuator and provided inside or outside a vehicular cabin is also provided. The method includes detecting utterances of a speaker by a microphone array and obtaining microphone signals corresponding to the utterances. The method further includes determining the position of the speaker on the basis of the microphone signals and automatically controlling the actuator of the element on the basis of the determined position of the speaker to adjust the element.

A semiconductor component (1) includes a substrate, an active area (2), formed in/on the substrate, and a passivation layer (5) which is provided at least above part of the active area (2). The passivation layer (5) at least partially comprises amorphous, hydrogen-doped carbon. The provision of a passivation layer of this type allows the semiconductor component (1) to be effectively protected against environmental influences.

The present invention relates to a method for improving acoustic noise attenuation, in which the method includes an adaptive control for partial-band echo compensation as well as global-band post-filtering for suppressing residual echo in hand-free devices. This method also uses a level balance as well as controllable frequency-selective echo compensation with partial-band processing. After the frequency-selective echo compensation, the signal is submitted to a post-filtering in another frequency-selective filter using a Wiener-equation adjustment algorithm (Wiener filtering). A single control value (increment vector) is used for controlling both the frequency-selective echo compensation and the other filter. This method can thus be implemented with a very reduced amount of calculations so that it can also be used in simple consumer-directed processors.

A method and apparatus for dehydrating sewage sludge is described. Sewage sludge is placed into a dehydration chamber. The sewage sludge is heated to convert moisture in the sewage sludge to steam and cause gasification. Steam and gases are drawn from the dehydration chamber into a condenser, where the steam is condensed to form hot water. Gases are drawn from the condenser to a burner.
