International Classification:

US Classification:

455425, 455 6714, 370241, 370249

Abstract:

A method for measuring perceptual quality of voice signals, audio signals, audio-video signals, and multimedia signals in communication equipment in an operational embodiment communicates a processed test signal via a network from a first device to a second device. The processed test signal is then received by an equipment under test, which further processes the processed test signal to recover a representation of the test signal. The recovered test signal is then objectively analyzed to determine a measure of perceptual quality by comparing the recovered test signal to a pre-stored representation of the test signal. A quality measurement unit that conveniently attaches to equipment under test identifies and evaluates quality of recovered test signals communicated from a remote device, or a test signal communicated by the equipment under test. In the latter case, the quality measurement unit communicates with both the equipment under test and with the network, so that the quality measurement unit itself receives a representation of the communicated test signal by the equipment under test.

US Classification:

704216, 7042001, 379 102, 379 2703

Abstract:

A method for providing real-time perceptual quality measurements of an audio signal ( ) in which a quality test signal, including an audio test signal, is received by equipment under test. Playback of a pre-stored representation of the audio signal is coarsely synchronized ( ) to the received audio test signal, for example, utilizing a synchronizing pulse in a header of the quality test signal. The playback is then finely synchronized ( ) to the received audio signal, for example, by comparing data in a windowed portion of the received audio test signal and a windowed portion of the pre-stored representation of the audio test signal and by adjusting a windowed portion of the pre-stored representation of the audio test signal in accordance with results of the comparison. A window of the received audio test singal is then compared ( ) to a portion of the finely synchronized play back of the pre-stored representation of the audio test signal to output a quality measurement of the received audio test signal.

Abstract:

A wafer stage assembly is provided to be used in combination with a projection lens assembly, such as in a semiconductor wafer manufacturing process. The wafer stage assembly includes a wafer table supported and positioned by a wafer stage and a wafer stage base for carrying a semiconductor wafer. The wafer stage assembly also includes a plurality of sets of sensors to determine a position and a rotation of the wafer table in six degrees of freedom relative to the projection lens assembly. A first set of sensors determines a position and a rotation of the wafer table relative to the projection lens assembly in at least one of the six degrees of freedom, while a second set of sensors determines a position and a rotation of the wafer table relative to the wafer stage base in the remaining of the six degrees of freedom.
