Abstract:
The present invention relates to a device and method for measuring a user's heart rate. In order to provide a reliable and inexpensive heart rate measuring technique, a device (1) and a method for measuring a user's heart rate is suggested in which the relative movement between a heart rate sensor (2) and the user is detected to generate a correction signal for removing motion artifacts caused by a user' s movement.

Furthermore the invention is related to a device (6) for positioning and/or alignment of at least two electrode patches (1) on parts of a human body with at least two positioning heads (7), which are spaced apart from each other by a coupling (8), the positioning heads (7) comprising at least one retainer (9), wherein at least one location pin (10) arranged on each electrode patch (1) meshes with the retainer (9) in order to align the patches (1) with each other.
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 device to carry out a bioelectrical interaction with an individual by means of electrodes 29, 29a whereby an on-demand verification of the integrity of the electrical contact of the electrodes is implemented. The device 20 comprises a control unit 22 arranged to determine an occurrence of the predefined event related to a quality of a measured signal. In case the predetermined event is detected, the control unit 22 actuates the testing means 24. The testing means is arranged to generate the test signals, I1,12 and to apply them via a coupling circuit 23, 23a to the electrodes. In case it is desired that cumulative information about the contact integrity is obtained, is it sufficient to apply a single test signal per electrode. In case it is required to determine which of the electrodes has lost its contact, a sequence of test signals is generated by the sequencer 24b. The response signal from the electrodes 29, 29a is forwarded to the input filter 26, which is preferably also used for a normal signal analysis. The signal from the input filter 26 is directed via the input impedance 25, 25a to the input amplifier 28. The amplified response signal is forwarded to the signal processing means 30 which is arranged to analyze the response signal. Preferably, an amplitude analysis is done. The signal from the signal processing means 30 is supplied to the analog-to-digital converter (ADC) 32 after which a digital processing of the response signal is carried out by means of a further processing unit 34. In case the further processing unit 34 determines that the integrity of the contact is below the allowable level, the lead-off indicator 36 is actuated.
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).
