摘要： The calibration cuvette apparatus for storing and calibrating a chemical sensor in a tonometered solution includes an upper cuvette section and a lower cylindrical valve section for alternately sealing the cuvette section and admitting a gas mixture to the cuvette section. The upper cuvette section has relatively narrow diameter upper and lower ends on either side of a wide diameter middle portion. The cuvette section is adapted to receive the sensor and retain the sensor in a fluid bath in the cuvette section so that the chemical sensor portion is disposed approximately in the center of the wide middle portion of the cuvette section. The chamber formed within the cuvette section is thus shaped so as to maintain the sensor in a position in the fluid bath so that any gas bubbles within the chamber will not dry the sensor. A lower end portion of the cuvette section includes a gas communication inlet for introducing gas into said chamber to equilibrate the tonometered buffer solution.

摘要： A signalling tone detector for use in a communications network carrying voice traffic incorporating single frequency and dual frequency signalling tones comprises a first output path, a second output path, and a switch arranged to selectively couple an input signal to one or other of the output paths. The detector is used for the selective disablement of an echo canceller in the presence of signalling tones.

摘要： A received OFDM signal is demodulated by sampling the OFDM signal at successive time instants and computing a Fourier transform of the samples for a block of time instants. In addition, a sliding Fourier transform is computed at every new one of the same input samples, to extract a pilot frequency tone. From results of the sliding Fourier transform a frequency error signal is detected. This signal is fed back the in a frequency synchronization feedback loop. The frequency synchronization feedback loop may be used to track the pilot tone by adjusting a phase correction signal and/or to track sample clock frequency variations.
