摘要:
A microphone array-based audio system that supports representations of auditory scenes using second-order (or higher) harmonic expansions based on the audio signals generated by the microphone array. In one embodiment, a plurality of audio sensors are mounted on the surface of an acoustically rigid sphere. The number and location of the audio sensors on the sphere are designed to enable the audio signals generated by those sensors to be decomposed into a set of eigenbeams having at least one eigenbeam of order two (or higher). Beamforming (e.g., steering, weighting, and summing) can then be applied to the resulting eigenbeam outputs to generate one or more channels of audio signals that can be utilized to accurately render an auditory scene. Alternative embodiments include using shapes other than spheres, using acoustically soft spheres and/or positioning audio sensors in two or more concentric patterns.

A method and an apparatus are provided for carrying out integrity tests of at least one filter element, arranged within a filter housing, with porous filter materials. Sensors are provided for measuring the sound generated by a test fluid when it flows through the filter element. The method includes applying a test fluid to a first side of the filter materials of the filter element while maintaining a constant fluid pressure, measuring the body-borne sound and/or the vibrations caused by test fluid flowing through the filter materials by sensors, and comparing the body-borne sound and/or the vibrations with the body-borne sound and/or the vibrations of an integral, identical filter element, measured under identical conditions.

A cleaning process is provided for a test apparatus that has a switch, external connections and internal volumes that can come into contact with a fluid from a filter to be tested or a container to be tested. The cleaning process includes selecting one or more internal volumes to be cleaned, cleaning the selected internal volumes with a cleaning fluid by a corresponding switching of the switch, at least partially draining the cleaning fluid left in the selected internal volumes after cleaning, and flushing the selected internal volumes with a flushing fluid different from the cleaning fluid. Also provided are a computer program product for performing the cleaning process, a cleaning apparatus, and a test apparatus for testing filters and containers.

An on-chip event timer apparatus including a hardware timer and a debug interface. The hardware timer includes at least an up-counter for counting clocks of a clock signal, a match register for storing a programmable count value, and a comparator for monitoring whether the up-counter's count value matches the count value of the match register. The debug interface includes enable control unit for enabling the up-counter's operation based on a pre-defined relationship between a state of an enabled signal supplied to said up-counter and an internal state of the hardware timer. Additionally, the debug interface may comprise a clock divider connected to the enable control unit to reduce the clock's frequency in accordance with a pre-programmed divider value. Based on the received clock with the reduced clock frequency, the enable control unit adapts the up-counter's processing speed to the reduced clock frequency.
