A method for constructing geo-location service replies (e.g. “You are near Bob's Café”, or “Proceed one block north to Bob's Café”) based on landmark-related relevance factors (e.g. if the user's location is close to a known landmark or sponsored location) to serve to a client terminal (e.g. a user's a mobile telephone, a smart phone, a GPS terminal). The system receives a user's geo-location service request (e.g. “Where am I”), and proceeds to construct one or more response candidates to service the user's geo-location service request. Candidate replies are then scored based on relevance factors (e.g. does the candidate location relate to the user's recent geo-service queries, is there a sponsored landmark in general proximity, etc), and high scoring geo-service replies are sent to the user's client terminal. In some cases, more than one relevance factor is considered (e.g. proximity relevance, visibility relevance, familiarity relevance, etc).

The present invention is a method and system for continuously monitoring cardiac output. In a preferred embodiment, the method and system of the present invention comprises a pneumotachograph, differential pressure transducer, and a signal amplifier/conditioner interconnected to a programmed digital computer. A patient, preferably, inserts the pneumotachograph in his mouth or, alternatively, the pneumotachograph is connected to a patient's tracheal cannula. As the patient exhales and inhales the differential pressure transducer measures the drop in pressure as air flows through the pneumotachograph thereby producing a weak electrical signal non-linearly proportional to flow. Next, the weak signal is directed through the amplifier/signal conditioner which increases the amplitude and removes some of the noise contained in the transducer output. A digital computer is then utilized to convert the analog time varying electrical signal into a stream of digital data, store it on disk, display it in real time and processes the signal using an experimentally determined correlation factor and mathematical equations relating the fluctuations in air flow with stroke volume to obtain the cardiac output.
