Publication number: 20120232420Abstract: (EN) Respiration of a patient can be monitored by means of a device (ASD) that has the following characteristics. An inlet (IL) receives a pressurized airflow of breathable air from an airflow source. An outlet (OL) applies the pressurized airflow to a mask worn by the patient. An airflow path (AFP) is arranged between the inlet (IL) and the outlet (OL). The airflow path (AFP) has an axis (AX) and exhibits a decrease (??D) in diameter followed by an increase (+?D) in diameter in a direction from the inlet (IL) to the outlet (OL). The increase (+?D) in diameter comprises an initial portion (WI) in which the diameter increases according to a slope (?) of less than 10° with respect to the axis (AX). A pressure measurement arrangement (PS1, PS2) provides an indication (SO) of a pressure difference in the pressurized airflow between two sections (IN, T) of the airflow path that have different diameters.Type: ApplicationFiled: December 1, 2010Publication date: September 13, 2012Applicant: SRETTInventor: Philippe Salamitou

Patent number: 7602668Abstract: Sensors located in the vicinity of a hydrocarbon-producing well receive power and communicate with one or more hubs located in the well or at the outer surface of a casing by means of elastodynamic waves. Each hub incorporates a plurality of transducers which permit focusing of the emitted elastodynamic waves. In order to concentrate the energy on a single sensor, or a group of sensors arranged in a cluster. Hubs and sensors communicate by exchanging, modulated elastodynamic waves. Sensors belonging to a cluster may transmit, properly time-shifted elastodynamic waves, in order to collectively focus their energy in the direction of a hub. Time synchronization between the sensors within a cluster may be accomplished by means of electromagnetic fields which travel much faster than elastodynamic waves, but can only propagate over short distances in typical formations.Type: GrantFiled: November 3, 2006Date of Patent: October 13, 2009Assignee: Schlumberger Technology CorporationInventors: Kenneth Kin-nam Liang, Jacques Jundt, Philippe Salamitou
