摘要： Single hand supportable and operable apparatus for providing an output signal characteristic of the morphology of a respiratory tract includes an acoustic pipe for exchanging acoustical energy with the tract. The pipe has an open first end in communication with an opening in the respiratory tract. A transducer, such as a loudspeaker, is coupled to the pipe for launching acoustical energy into the pipe, producing an incident wave towards the opening in the tract and a reflected wave to form a transient wave field in the pipe representative of the morphology of the tract. Preferably, first and second pressure wave sensing transducers, such as microphones, mounted along the length of the pipe in spaced relationship provide first and second transduced signals representative of the transient wave field. A processor processes the first and second transduced signals to provide an output signal characteristic of the morphology of the tract, such as the cross-sectional area as a function of the distance from the opening in the tract.

摘要： A signal power control device comprises two amplification channels. A first amplification channel comprises a first transconductance amplifier and a second amplification channel comprises an attenuator mounted in series with a second transconductance amplifier. Gain adjustment means allow the respective gains of the first and the second amplifier to be controlled independently, according to laws, ensuring optimum output dynamics across the entire gain range of the power control device.

摘要： A filtering device based on an active transconductance filter includes auto-calibration means, the principle of calibration consisting in slaving the power supply current for the filter as a function of the phase shift between a second signal shifted by a first predetermined phase shift with respect to a periodic reference signal, and the output signal of the filter in response to a first signal shifted by a second predetermined phase shift with respect to the periodic reference signal, the slaving tending to minimize the phase shift between the output signal of the filter and the second signal.

摘要： Apparatus provides an output signal characteristic of the geometry of a confined volume. There is a conduit with an open first end for exchanging acoustical energy with the confined volume. An electroacoustical transducer is coupled to the conduit for launching acoustical energy into the conduit towards the opening in the confined volume producing an incident wave and a reflected wave to form a wave field representative of the geometry of the confined volume. In one embodiment, the acoustical energy is launched into a sidewall of the tube. At least first and second pressure-wave-sensing transducers are mounted along the length of the conduit in spaced relationship for providing first and second transduced signals representative of the wave field at spaced locations in the conduit. A processor processes the first and second transduced signals to provide an output signal characteristic of the geometry of the confined volume. In one embodiment, the processor provides high-pass filtering of the impulse response.
