Abstract: Methods and systems consistent with the present invention provide an improved sample-rate converter that overcomes the limitations of conventional sample-rate converters. The improved system comprises a simple asynchronous sample-rate converter and synchronous sample-rate converter. The output of the simple asynchronous sample-rate converter is connected to the input of the synchronous sample-rate converter. In an alternative embodiment, the output of the synchronous sample-rate converter is connected to the input of the simple asynchronous sample-rate converter.

Abstract: A system and method for predicting and limiting distortion of an amplified signal is described. The system includes a variable total harmonic distortion (“THD”) clipping predictor, a comparator in communication with the variable THD clipping predictor and a distortion limiter in communication with the comparator. As for the method, a reference power supply value, a maximum desired total harmonic distortion value and a preamplified signal value is provided. A THD output threshold value is calculated based on the reference power supply value and the maximum desired THD value and is then compared to the preamplified signal value. Depending on if the preamplified signal value is greater than or less than the THD output threshold value, the amplitude of the preamplified signal may be increased or decreased.

Abstract: A humidifier in which the temperature of the humidified gases leaving the humidifying chamber of the humidifier is measured. The measured temperature is compared with a predetermined temperature required for a minimum humidity level for humidified gases supplied to a patient and if the measured temperature is less from the predetermined temperature a warning is provided. The humidifier also has a securing device for securing the humidifying chamber to the heater plate of the humidifier. The securing device comprises a sprung gate member which is biased in an upward position to prevent the humidifying chamber from being removed but may be pressed downwardly by a user in order to engage or remove the chamber.

Abstract: A method and means for delivering the liquid generated by a coreflood experiment to test tubes and the gas so generated to a gas outlet. A mixture of gas and liquid is fed through an axially rotating tube extending through the central portion of a sealed chamber in which the test tubes are arranged in a circular path. The tube has a transversely extending delivery portion which deposits liquid into the test tubes, while gas is collected through a conduit leading from the chamber. The tube is incrementally rotated through a mechanism which allows fluid from the core sample to flow into the tube at the same back pressure under which the experiment takes place.
