Patent CA-2426622-A1 (CA)
Inventor: PINTO LISA
IPC: A61B5/025
Filed: 2003-04-25
Abstract: A method and a device for measuring systolic and diastolic blood pressure and heart rate in an environment comprising extreme levels of noise and vibrations is disclosed. Blood pressure signals corresponding to the Korotkotf sounds are detected using a first acoustic sensor or array of sensors, placed on the patient's skin over the brachial artery. A second acoustic trmsducer is placed on the outside of a pressure cuff the patient away for detecting noise and vibrations. Pressure is applied to the artery using the pressure cuff forcing the artery to close. The pressure is them reduced and while reducing the pressure the acoustic signals detected by the first and second acoustic sensor as well as a signal indicative of the pressure applied to the artery are provided to a processor. The signal of the first acoustic sensor is then processed using an adaptive interferes canceller algorithm with the signal of the second acoustic sensor as interferer. From the processed signal heart beat pulses are determined and relating the heart beat pulses to the pressure signal provides the systolic and diastolic blood pressure. Use of the adaptive interferes canceller provides goad results for measurements performed under extreme levels of noise and vibrations such as aboard a helicopter, naval vessels, ambulances and noisy emergency rooms.

Abstract: A process for liquefying natural gas in conjunction with processing natural gas to recover natural gas liquids (NGL) is disclosed. In the process, the natural gas stream to be liquefied is taken from one of the streams in the NGL  recovery plant and cooled under pressure to condense it. A distillation stream is withdrawn from the NGL recovery plant to provide some of the cooling required to condense the natural gas stream. The condensed natural gas stream is expanded (14) to an intermediate pressure and supplied to a mid-column feed point on a distillation column (17). The bottom product (41) from this distillation column (17) preferentially contains the majority of any hydrocarbons heavier than methane that would otherwise reduce the purity of the liquefied natural gas, and is routed to the NGL recovery plant so that these heavier hydrocarbons can be recovered in the NGL product.
