Abstract: A method and a system for noise discrimination, the method comprising measuring noise levels of a noise source, measuring noise levels at a target location positioned at a distance from the noise source, measuring wind speed and direction in an area comprising the noise source and the target location, filtering transient short-duration events from the noise levels measured at the noise source, yielding filtered noise levels of the noise source, filtering transient short-duration events from the noise levels measured at the target location, yielding filtered noise levels of the target location, measuring a sound transfer function between the noise source and the target location using the filtered noise levels, comparing the measured sound transfer function with a reference transfer function; and when the difference between the measured transfer function and the reference transfer function is above a predetermined threshold, determining a probability that noise at the location originates from the noise source.

Abstract: A modular laboratory furniture assembly having a work surface with front legs and back leg members, each of the back leg members being configured for coupling to corresponding back leg members of a second work surface positioned in a back to back position to the back leg members and each being securable to two back leg members of the second work surface forming a combined vertical elongated service cavity therein.

Abstract: Digital-type hands-free telephone apparatus is provided including a microcontroller, an audio board and a COFIDEC circuit, in which the microcontroller permanently calculates the average values of 16 successive samples on each one of the send and receive channels and deduces therefrom which channel is to be enabled while attenuating the other using tables provided in ROM memory.

Abstract: The telephone station has a first attenuator inserted in a transmission channel, and a second attenuator inserted in a reception channel. Each attenuator has a variable impedance mounted in shunt on the corresponding channel. A circuit controls the attenuators as a function of the relative levels of signals collected respectively from the transmission and reception channels. A bridge circuit introduces a difference between the levels of the signals collected respectively from the two channels. The bridge circuit includes a resistor bridge formed by two fixed resistors inserted in each channel upstream of the attenuator which is associated with said channel, and by a variable impedance which constitutes the attenuator. The common node of the two fixed resistors is the point of collection of the signal from each channel.

Abstract: A method of treating insufficiencies in hematosis, such as hypoxemia, cardiac insufficiency, and polyglobulia, involving treatment of a patient suffering from such insufficiency with the compound almitrine or a pharmaceutically-acceptable salt thereof in extremely low daily dosages, between 0.5 and 3 mg/kg orally or 0.05 to 0.3 mg/kg intravenously, an oral unit dosage form of the said active ingredient, containing between 20 and 70 mg of active ingredient together with a pharmaceutically-acceptable carrier or diluent, preferably about 50 mg of the active ingredient.
