Abstract:
An apparatus is described to measure pulse wave velocity, PWV, along a pathway in the cardiovascular system of a subject and comprising a first sensor coupled to a processor, a second sensor coupled to the processor, the processor arranged to calculate the PWV from measured and calculated values of the sensors. At least one sensor is a transducer arranged to emit electromagnetic signals at a certain frequency and detect doppler shifted reflected electromagnetic signals representative of a pulsatile motion occurring at the respective position in the cardiovascular system. The transducer can be applied directly to the skin, or can be applied to clothing covering skin, and allows the calculation of pulse wave velocity, PWV, without the use of acoustic gel.
Abstract:
A system (6) arranged to route a dialog between an operator of a call center and a customer. Said system comprising a communication script (44) arranged to follow a scenario corresponding to a customer's case by means of presenting a plurality of messages to the operator. Said system further comprising means (3,7) for determining a type of the scenario, means (11) for determining a current state of the scenario and a generator (9) of the communication script (44). Said generator being arranged to select a plurality of messages (44a, 44b, 44c) from a database of messages (10) in compliance with said type and said current state in order to obtain a plurality of selected messages. Ranking means (14b) are arranged to rank the selected messages, wherein the message with a higher relevance to the current state of the scenario being ranked higher. A user interface (8) arranged to present the selected messages together with their rank (46a, 46b, 46c) to the operator in a list (18).
